Target lemma: shake
Target surface form: shaking
Context:
I decided to brave the storm. There was a horrible smell of gas as I passed the Chevron refinery before crossing the Richmond-San Rafael Bridge. I could also see the clouds across the bay from the horrible fire in the Marina District of San Francisco. I have felt many aftershocks. My back is still in knots and my hands are still shaking. I think a few of the aftershocks might just be my body <t>shaking</t>. 1:11 a.m.

reasoning_content:
We need perform WSD for target word "shaking" form of lemma shake. Context: "I have felt many aftershocks. My back is still in knots and my hands are still shaking. I think a few of the aftershocks might just be my body <t>shaking</t>." Need select one best indexed sense from listed senses. The target surface form is "shaking" but token used as noun? Actually "my body shaking" is gerund; it refers to body moving/vibrating, likely from earthquake aftershocks or nervousness. The sentence says hands are shaking, and aftershocks might be body shaking. So sense "move back and forth" (sense 1) definition=move or cause to move back and forth, synonyms=agitate, examples include My hands were shaking. That fits well: body shaking. But there is sense 2: move with or as if with a tremor; synonyms=didder; examples his hands shook. This also fits trembling. How to choose between 1 and 2? They differ by synset? Let's examine glosses carefully.

Sense 1: sense_key=shake%2:38:00:: definition=move or cause to move back and forth; synonyms=agitate; examples The chemist shook the flask vigorously; My hands were shaking. Frames likely transitive/intransitive? Sense 2: sense_key=shake%2:29:00:: definition=move with or as if with a tremor; synonyms=didder; examples his hands shook. Verb frames maybe intransitive "didder" = "shake with nervousness or thrill". It might be specific to trembling as from cold, fear, excitement. But context: aftershocks cause body shaking? i.e. earthquake tremors. The person mentions aftershocks, hands shaking. "a few of the aftershocks might just be my body shaking" suggests ambiguity between actual earthquake and bodily shaking. Body shaking could be a tremor (trembling) due to aftershocks? It's not specified nervousness but because of aftershocks. Both senses plausible.

We must use context examples synonyms etc. Distinguish: sense 1 "My hands were shaking" example exactly matches. Sense 2 "his hands shook" also matches but synset maybe separate? Need be precise. In WordNet, "shake.v.01" probably = "move or cause to move back and forth"; "shake.v.02" maybe = "move with or as if with a tremor" (tremble). But examples: v.01 examples: "The chemist shook the bottle"; "My hands were shaking". v.02 examples: "his hands shook". Why both include hands shaking? WN semantics subtle: v.01 includes move back and forth (oscillate) generally; v.02 more specific tremor like from cold/fear. In this context, body shaking after aftershocks; is it voluntary/oscillatory or trembling due to stress? The phrase "my body shaking" is probably due to actual earthquake ground shaking? Wait narrative of earthquake survivor: "I have felt many aftershocks. My back is still in knots and my hands are still shaking. I think a few of the aftershocks might just be my body shaking." The speaker can't tell whether tremors are aftershocks or own body shaking. So "body shaking" = whole body vibrating, likely caused by stress/aftershocks? It's literally the body moving back and forth (trembling). Which sense covers "body shaking"? The examples for sense 1 include "The chemist shook the flask vigorously; My hands were shaking". That covers body parts moving back and forth. Sense 2 examples "his hands shook" and synonyms didder (tremble, shiver, shudder?), definition "move with or as if with a tremor"—more about pathological/nervous trembling. The context: "My hands are still shaking" and "my body <t>shaking</t>". The target is "shaking" gerund but WSD for word "shake" in that context.

Need choose single best indexed sense. Which index corresponds? 1: sense1 etc. We need output JSON {"sense_index"}. Best index likely 1 because definition "move or cause to move back and forth", examples explicit My hands were shaking. But sense 2 also explicit his hands shook. Hmm. Let's examine mapping: sense 1's example "My hands were shaking" exactly context. Sense 2 includes tremor, as if (trembling) due to aftershocks? The phrase "a few of the aftershocks might just be my body shaking" uses "shaking" as event, not "shook". It could be general motion. If earthquake creates ground shaking, word form "shaking" usually sense 1 (the earthquake made the building shake). When person says "my body is shaking," it is a body part shaking (trembling) due to fear. The previous "my hands are still shaking" relates to nervousness, aftershocks. Hands shaking from aftershocks—could be "trembling" (sense 2). But WordNet sense 2 definition is "move with or as if with a tremor". In the example "his hands shook", didder. That is likely what is meant. However the first instance "My hands are still shaking" could also map to sense 2 not 1. The target specifically "my body shaking" the gerund; but instructions: target surface form "shaking"; target lemma "shake"; context includes it in "my body <t>shaking</t>" and earlier "my hands are still shaking". The best indexed sense for target maybe same as earlier instance? We need not distinguish occurrence? Well target token highlighted is "shaking" in "my body shaking". For WSD, highlighted token is the one to disambiguate. The phrase "my body shaking" could be an aftershock (earthquake aftershock) vs body (person) shaking. Is it body shaking as in trembling or as in the person's body quivering due to aftershocks? Yes.

Let's see all candidate definitions:
1 move or cause to move back and forth [agitate; flask, hands]
2 move with or as if with a tremor [didder; his hands shook]
3 shake or vibrate rapidly and intensively [judder; old engine]
4 move back and forth or sideways [rock, sway; ship, building]
5 undermine/cause to waver
6 stir feelings
7 get rid of
8 bring to specified condition by shaking
9 shake a body part to communicate greeting/feeling/cognitive state

Since it's body (or building? no, body) not a vehicle/engine or building. Not communication. Not transitive. Between 1,2,4 maybe "my body" like tall building swayed? Body isn't an inanimate object but a person. However an earthquake causes building to shake (move back and forth) = sense 4? Definition says move back and forth or sideways, synonyms rock/sway, examples: the ship was rocking; the tall building swayed. "My body shaking" due to aftershocks could be like a building shaken by earthquake? Maybe. But "body" is human body, so not rock/sway.

Sense 2 exact "tremor". Given earthquake aftershocks, body shaking after shocks, sense 2 seems very close: trembling/tremor. But sense 1 includes general oscillating (move or cause to move back and forth), and the example "My hands were shaking" maybe the prototypical example for using shake.v.01 intransitively. Let's check WordNet indices:

WordNet 3.1: shake.v.01: (move or cause to move back and forth) "The chemist shook the flask vigorously"; "My hands were shaking". This synset likely includes both transitive and intransitive, has hypernym move. verb frames: something --s, somebody --s something. In PWN, "agitate" as cause to move, but "shake.v.01" has agitate? Actually WordNet for "shake" has "agitate" as derivationally related form? Hmm.

shake.v.02: (move with or as if with a tremor) "his hands shook". Hypernym maybe "move"? Synset includes "tremble, didder"? Wait n. didder vs v. didder. Let's think: "tremor.v.01"? In WN, "tremble" is separate but "shake" sense 2 maybe "shake or vibrate rapidly and ..."? Actually ordering by frequency maybe different.

Regardless, we must decide. Let's parse candidate senses. They gave indexes 1-9 with keys. We can inspect sense_key. Lexical file numbers:
1: shake%2:38:00:: (2: change by reversible?) Actually 2:38 = "move"? In WN verb frames, lexicographer files: 02= stative? Hmm no, sense key lex numbers for verbs: 00 unknown. 2:38 is "Contact"? Not sure. Actually 02:29 = "Perception"? No.

Sense_key format: lemma%lexical_filenum:lex_id:head? Let's recall. For verbs, lexical_filenum range 00-45: 35=contact, 38=motion? 29=perception? 44=weather? Let me recall WordNet verb file numbers: 13=verb.competition, 29=verb.perception? Actually verb frame numbers: 29 = 'verb.perception' maybe. 30 = 'verb.contact'? 35= 'verb.motion'? Hm.

Let's check: WordNet verb file numbers: 01,11,13,14,15,17,18,19,20,21,22,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43. Known: 29 = verb.perception? e.g. "look" 29? Wait WordNet noun file 09 = noun.perception. For verbs: 29 = verb.perception? 35 = verb.contact; 36 = verb.competition; 38 = verb.motion? 09 not relevant. Senses here:
- 2:38:00 = verb.motion likely (move back and forth)
- 2:29:00 = verb.perception? Maybe "trembling" perceived?
- 2:38:01 another verb.motion
- 2:38:02 another verb.motion
- 2:30 = verb.contact? "undermine" contact? no maybe verb.emotion?
- 2:37 = verb.communication? Hm.

The basic "move" senses are 38. So sense 1 is primary verb.motion generic. Sense 2 is 29 maybe verb.perception? It has a special nuance of "tremor". Does body shaking from earthquake最好用 sense 1? It is "my body moving back and forth" (from aftershocks). The body is an object being moved or moving; an external force (aftershocks) might cause it to move. In "my body shaking", syntactically intransitive with progressive. Definition of sense1 covers intransitive "My hands were shaking". So sense1 likely primary correct sense.

But the context contains "I think a few of the aftershocks might just be my body <t>shaking</t>." The target is conception of action: body shaking. The reader might think aftershocks are their body trembling. "My body shaking" is intransitive but caused not by their agency. Sense1 allows "move or cause to move back and forth" regardless agency? It can be either transitive or intransitive: e.g., "My hands were shaking" hands moved back and forth involuntary. Sense2 "move with or as if with a tremor" specifically involuntary trembling. Which is more appropriate for bodily trembling? In dictionaries, "shake" (v.) sense 2 often means "to move irregularly to and fro" while "tremble" is "to shake with short, quick movements". In WordNet, the sense 2 might specifically be trembling, mapping to "didder" and includes "his hands shook". But why separate from sense1? Let's look at examples: sense1 includes trans and intrans. Sense2 only intrans "his hands shook". The sense 2 synset may include "tremor"? The synonyms are from semantically related list? Note "didder" as noun maybe? Did the LDC WSD? Wait the candidate list uses synonyms like "agitate" for sense1, "didder" for sense2. The list may not be synonyms in synset but "similar" terms? They used "synonyms=agitate" for sense1, but agitate isn't direct synonym? Actually wordnet includes "agitate" as list to "shake.v.09"? No.

Possible dataset: Could be OntoNotes/WordNet WSD. For "shake" with these glosses, the answer should be the sense that best matches the specific meaning: "my body shaking" aftershocks—earthquake ground motion vs person's trembling.

We need output JSON rather than explanations.

Let's analyze further with semantic roles. "My hands are still shaking." Shaking like trembling. Then "I think a few of the aftershocks might just be my body <t>shaking</t>." Here they worry that perceived aftershocks may actually be their own body quivering because of fright. That's trembling again. "Body shaking" due to fear. That aligns with sense 2 (move with tremor) / maybe sense 1 (hands shaking). Which gloss better? The phrase "my body shaking" is essentially the same as "my hands were shaking" in previous sentence. If we decide sense for "My hands were shaking" using examples, both senses 1 and 2 have that. However example of sense1 says "My hands were shaking" explicitly. Example of sense2 says "his hands shook" explicitly. In training corpora, "hands shaking" might map to either. Which one does WordNet assign? Let's see actual WordNet mapping for "My hands were shaking". I can try to infer from semantic. In WordNet, the primary sense 1 of shake is definitely "The convict's hands were shaking"; that is prototypical. But WordNet gloss v.02 "shake.v.02: move or cause to move with short jerky or vibrating motions" maybe with examples: "He shook with fright"; "his hands shook"? Let me think of actual WordNet entries for 'shake':

From memory:
- shake (v.) — move or cause to move back and forth; "The chemist shook the flask vigorously"; "My hands were shaking".
- shake (v.) — move with or as if with a tremor; "his hands shook".
- shake (v.) — shake or vibrate rapidly and intensively; "The old engine was juddering".
- shake (v.) — move back and forth or sideways; "the ship was rocking"; "the tall building swayed" (synset: rock, sway, shake)?? Actually rock and sway synset includes 'sway', 'rock'. 'shake' maybe not. Wait "move back and forth or sideways" is probably the synset for "rock, sway, shake". It includes "the ship was rocking" and "The baby was rocking".
- shake (v.) — undermine or cause to waver.
- shake (v.) — stir the feelings.
- shake (v.) — get rid of.
- shake (v.) — bring to specified condition.
- shake (v.) — shake (body part) to communicate.

So sense1 vs sense2: Both "hands shaking" but sense1 generic move back and forth; sense2 specifically trembling. Which one would a person say "my hands are still shaking" after an earthquake? If intent fear, they'd tremble => sense2. If intent the ground was shaking their hands => sense1? Actually if you are in an earthquake, your body and hands can shake due to ground motion; so it's "the ground caused my hands to shake" (move back and forth) => sense1. But author mentions "horrible fire", aftershocks, back in knots, hands shaking—likely from stress/nerves not the earthquake physically moving hands at that moment. "My back is still in knots" is tension/stress symptom. "My hands are still shaking" could be stress tremor. So sense 2 more appropriate. But sense 2's adverb phrase "with a tremor" maps to fear/trembling. However the target is "body shaking" as possible cause of felt aftershocks; is it more like body shaking due to aftershocks (not voluntary)? It is trembling/shuddering.

Let's consider the list order: It seems sense 1 is main sense, sense 2 is tremble. The task: choose best indexed sense. We should not hedge. Need final JSON only. Need pick one. Let's use definitions examples.

Sense 1 examples cover "My hands were shaking" exactly and definition "move or cause to move back and forth". This is likely the sense for a body part moving (trembling too). The synonym "agitate" suggests transitive and physical. Definition "move or cause to move back and forth" covers both cause and caused. "My body shaking" intransitively can be: body moves back and forth. This matches better because the body is an object being moved by aftershocks or internal tremor.

Sense 2 definition "move with or as if with a tremor" and examples "his hands shook" is very close. Synonym didder = tremble. "Tremor" suggests involuntary shaking e.g., from fear. Body shaking from stress = tremble. The previous "my hands are still shaking" and "back in knots" suggests stress/tension. So sense 2 arguably best. But the first sentence already said "my hands are still shaking", and then "aftershocks might just be my body shaking" conceptually: Are the aftershocks real or my own trembling? The WSD target is "shaking" in the second thought, referring to bodily trembling rather than perceived aftershocks. So sense 2.

But WN specificity analysis: Does a person say "my body is shaking" due to cold/fear usually map to "didder" or "tremble"? In WordNet, "didder" may mean "tremble, throb"? Hmm. The second sense definition given is "move with or as if with a tremor"; examples his hands shook. It seems to capture Parkinson's/"his hands shook" as from illness/old age. In context, aftershocks and stress, it is likely a tremor. But the author's "hands are still shaking" more likely due to physical exertion/stress; but "tremor" exactly.

Could sense 4 apply? "the ship was rocking; the tall building swayed"—if "my body" as an object experiencing earthquake, it could "shake" (sway). But body is not a building/ship. Not appropriate.

Sense 3 (judder) old engine = rapid vibration. Not body.

Sense 5 not possible.

So between 1 and 2. Let's think about corpus annotation likely. The data appears generated from WordNet, perhaps from supervised WSD benchmark. Which sense would gold annotation choose for "hands are shaking" or "body shaking"? Let's simulate WordNet gloss mapping. When a word has two related senses, annotators use examples. Example in sense1 exactly: "My hands were shaking." The target phrase "my hands are still shaking" matches sense1 example exactly. The target phrase "my body <t>shaking</t>" matches "my hands were shaking" semantically. Therefore likely gold = sense1. But sense2 example "his hands shook" also matches. What's distinction? Maybe the expected sense for "shaking" as a state: "My hands were shaking" in sense1 because it is a generic shake (like container); sense2 for "his hands shook" generic statement? It's rare to distinguish. However WordNet sense 1 is the parent of sense2? Maybe sense2 is a troponym/hyponym of sense1? In WordNet hierarchies, "shake.v.02" might be under "tremble" not under "shake.v.01". Let's check hypernyms. If sense2 is a special kind of "shake" (move with tremor), its hypernyms could include "shake.v.01"? Let's try to recall WordNet net: Senses of "shake" verb:
01 (verb.motion) move or cause to move back and forth
  hypernym: move
02 (verb.motion) move with or as if with a tremor
  hypernym: shake (v.01)? Actually similar to "agitate"?
Maybe it inherits from 01. If so, it's more specific; fine-grained WSD selects the most specific applicable sense, so sense2 if body is trembling due to stress. This is "tremor".
But examples: The first example sense1 "The chemist shook the flask vigorously" = transitive; "My hands were shaking" attached to same sense = intransitive. In WordNet, sense 1 likely polysemous between factitive and inchoative, including when an object/person oscillates due to internal/external force. The phrase "My hands were shaking" can also mean nervous tremor, but maybe WordNet placed that example with sense1 because it is a general movement. Then sense2 with "his hands shook" might be a slight variation? Wait WordNet would not have two nearly identical senses with interchangeable examples. There must be subtle difference. Let's search memory: In WN, one sense is "shake with short, quick movements" (v.01). The other is "tremble or quake" (v.02). I'm uncertain.

Let's look up approximate WordNet data mentally:

Verb "shake" definitions (maybe from WN 3.0):
1. (3) shake, agitate — (move or cause to move back and forth; "The chemist shook the flask vigorously"; "My hands were shaking")
2. (3) didder, shudder, flop, shiver — (move with or as if with a tremor; "his hands shook")? Wait synonyms for sense2 might include "didder, shiver, shudder", not just didder. But user gave synonyms=didder. Actually maybe WordNet sense "shake.v.02": "didder, shiver, shudder" (?) The verb "didder" = "shake with nervousness or thrill".
3. (2) judder — (shake or vibrate rapidly and intensively; "The old engine was juddering")
4. (1) rock, sway, shake — (move back and forth or sideways; "the ship was rocking"; "the tall building swayed")
5. (3) weaken, undermine, etc.
6. stimulate, shake, shake up, excite, stir — (stir the feelings)
7. shake, shake off, throw off, escape from — (get rid of)
8. (1) shaken — (bring to a specified condition...)
9. nod, shake — (shake a body part...)

So senses 1 and 2 are distinct but somewhat overlapping. The second synset likely has words "didder", "shiver", "shudder", indicating a special kind of shaking due to cold/fear/nervousness. The author mentions back in knots and hands shaking—fear from aftershocks? Could be.

Now consider the syntactic structure: "my body <t>shaking</t>" as gerund within noun phrase: "a few of the aftershocks might just be my body shaking" i.e., an existential clause "might just be [my body shaking]" equivalent to "[that] my body is shaking". This gerund denotes the event of body shaking. The event is a physical movement, not emotional-effect-as-action. Compare sense 1 "The chemist shook the flask vigorously" is a physical action causing movement; "My hands were shaking" event. That likely.

If we interpret WSD with semantic types: "body" is animate object, "shaking" (intransitive) as a physical reaction to stress. The possible sense 2 "move with or as if with a tremor". The tremor can be due to cold/fear/excitement. Here due to aftershocks/nervousness. So sense 2 may be more fitting. But sense 1 also has example "My hands were shaking". Why is that exactly same context but in sense1? Let's examine the example under sense1: "My hands were shaking". When is that used? It can be from nervousness, cold, injury. In WordNet, that single example doesn't disambiguate; it just shows transitive/intransitive. The presence of that example under sense1 suggests WordNet treats "hands shaking" as a generic movement, not specifically nervous tremor. Then sense2 uses "his hands shook". Hmm. Why would WordNet split? It may use sense1 when the subject is animate/object without clear trembling semantics, and sense2 when subject is an abstract 'his hands' with trembling? Not clear. Let's look at synonyms: sense1 "agitate" is a near-synonym/acomp? "Agitate a liquid" not nervous. I think sense1 is the right generic. The task says "WordNet glosses are schematic; use context, examples, and synonyms." The context of aftershocks, fire, "knots" (stress). The synonym for sense2 "didder" has connotation of tremble/shake with nervousness or cold, e.g., "didder with delight/terror". That fits fear/stress. The examples for sense2 "his hands shook" is general though. But synonym is didder. "Move with a tremor" specifically from fear. So the emotion context (horrible smell of gas, fire, aftershocks) makes sense2 fit. But sense6 "stir feelings" no.

However "body shaking" as gerund refers to the action of the body, not to the person's emotion. The person is experiencing an event: body shaking. The cause is aftershocks, may just be body. This is not "shake" as transitive communication. It is physical movement. Sense1.

Let's see if synonyms examples support sense 1: "The chemist shook the flask vigorously" describes an external agent causing something to move back and forth. "My hands were shaking" describes a body part moving back and forth. These examples closely map. The sense1 definition includes cause to move as well as move by itself, so can fit aftershocks causing body to move. The participant says "a few of the aftershocks might just be my body shaking"; i.e., perhaps their body is what's being shaken (by internal tremors). Sense1 fits.

Sense2: examples "his hands shook" = similar but no specific cause. The context says "My back is still in knots and my hands are still shaking." Then "might just be my body shaking." The antecedent "my hands are still shaking" makes us think the highlighted target extends this: body shaking. If the first instance mapped to sense1 example "My hands were shaking", likely sense1. Is the first instance the same target? The target surface form is "shaking" in "body shaking". The previous "shaking" is not target but provides context. Fine-grained WSD judges each occurrence; context can determine.

I think the gold answer for such tasks in past may be sense index 1, because all "body/hands shaking" physically map to primary sense. But potential for sense 2.

Let's examine senses numeric mapping in relation to WordNet IDs. Candidate senses provided as key and gloss. If this is a specific NLP exercise, often the expected answer is the first sense for literal shaking. The phrase "my body shaking" likely aligns with "My hands were shaking" example in sense 1 (literal move back and forth). There is also sense4 with "rock/sway" but examples are buildings. Body in earthquake could "sway" but not "sway" unless losing balance; "my body" not tagged. Should we not choose sense4 because "body" can sway? Actually if the ground shakes, a person may sway; but "my body shaking" not "swaying". Definition says "move back and forth or sideways"—synonyms rock, sway. That could apply to body if instable. But "my body" being an inanimate structure? Could be compared to a tall building; but body is flexible and can tremble. Sense4 may include 'recoil, stagger, totter' maybe? No.

Probably answer = 1. But we need be confident. Let's explore actual WordNet sense assignment for phrase "my body is shaking" from WSD corpora. Could search memory? Not possible offline, but model may have training data. The target context is from a diary or blog describing Loma Prieta earthquake? "Chevron refinery ... Richmond-San Rafael Bridge ... Marina District fire" — yes Loma Prieta quake. The person writes they have felt many aftershocks, hands shaking. The phrase "I think a few of the aftershocks might just be my body shaking" means they are not sure if ground is shaking (external) or if their body is trembling (internal/nervous). This is "body shaking" from nervousness/stress. If I say "my body is shaking" due to fear, I'd use the verb 'tremble' or generic 'shake'. In WordNet, 'tremble' is not "shake.v.02"? Let's recall: "tremble" v. = shake with short jerky movements. Is "shake" sense 2 "move with or as if with a tremor" essentially same as tremble. Then yes.

But the task says "Use sentence context, examples, synonyms to choose best indexed sense". We should examine all candidate gloss examples. Candidate 2's examples: "his hands shook" — exactly close. Candidate 1's examples: "My hands were shaking" — even closer surface form (progressive). Thus candidate 1 has example matching target form "shaking". Candidate 2 uses past "shook" (regular?). The target is present participle "shaking" used in progressive/gerund, which maps to "My hands were shaking" example (progressive). That syntax matches sense 1 better.

Also sense2's synonym "didder" is obscure; "didder with nervousness or thrill". Does context indicate "nervousness or thrill"? The author is frightened, but not necessarily delight. The phrase "My back is still in knots" indicates stress. So didder (tremble) fits. But didder specifically "shake nervously; vibrate with fear". Actually "didder" verb in WordNet? Let's recall: didder v.1 = "shake with fear"? maybe.

Let's think about subsumption. If sense2 is more specific (tremor), and if sense1 is general and includes these cases, choosing too-general would be wrong for fine-grained WSD. But definition of sense1 is "move or cause to move back and forth" not specifically trembling; but examples include hands shaking. It implies a deliberate or generic back-and-forth. The context of aftershocks (external shaking) maybe generic. If body shaking due to stress, it is more specific tremor. Fine-grained wants specific, so sense2.

But is "the ground/earthquake is shaking" sense1? Yes. If "the aftershocks might be my body shaking", they confuse one specific physical movement (earthquake) with another (tremble). Wait they compare categories: aftershocks vs body shaking. Are aftershocks "move or cause to move back and forth" (ground shaking) or body? Actually they think some aftershocks (sensed tremors) are actually their own body shaking. So the "body shaking" is analogous to earthquake shaking (rapid back-and-forth). An aftershock is a ground shake, likely sense1? Hmm.

Let's parse sentence: "I think a few of the aftershocks might just be my body <t>shaking</t>." This means: some instances where they perceived an aftershock, maybe the ground wasn't actually shaking; it was just their own body shaking due to nerves. So "body shaking" is a possible alternative explanation for the felt tremors. If aftershocks are "ground shaking" (move back and forth), body shaking is also "body moving back and forth" (same manner). The author explicitly says hands are still shaking. That's a physical observable. Could be generic.

Let's see whether "my body <t>shaking</t>" could be an attributive complement? "be my body <t>shaking</t>"—cleft? It shows gerund, not progressive. The word itself is neutral. Since there are two very close senses, but examples differ by "his hands shook" vs "My hands were shaking". I'm leaning sense 1 due to direct example and broad definition. However sense 2's specific tremor matches probable cause (fear). How to choose without hedging? Need final just JSON.

Let's also check whether sense 2 in sentence "his hands shook" — if context aftershocks/hands, maybe a person being cold? WordNet probably annotates examples that compare "his hands were shaking" to "his hands shook"? Since WNDS from WordNet examples, both exist. Which sense does WordNet put "My hands were shaking" into? I can try to recall exact WordNet entry output for "shake.v.01": Examples: "The chemist shook the flask vigorously"; "My hands were shaking". For "shake.v.02": examples: "his hands shook"; "The soprano's voice was trembling". Wait that's maybe "tremble" synset not shake. Actually "didder" = "tremble".

Let's consider actual WN synset names (not glosses):
1. `shake.v.01`: "agitate" maybe `didder`? Wait no, the synset for `shake` v.01 includes words: `do the shimmy`, `rattle`, etc.? Hmm.

From VerbNet: shake-22.3? e.g., "shiver", "tremble" are body-movement verbs.

Another angle: The target form is "shaking" as gerund inside nominal complement. For gerund senses, a dictionary might classify under noun? But data is verb senses only. The gerund denotes the activity. The activity "of my body shaking" is a physical change event. Candidate 1 (move/caused to move) is the action of moving back and forth. Candidate 2 (tremor) is also activity. The phrase "shaking body" could be like "a shaking building" = vibration.

If I had to make final call, I think the most natural/closest semantic match to the phrase "my body shaking" in this earthquake context is sense 1 "move or cause to move back and forth", because it is exactly analogous to examples "My hands were shaking". The author says "hands are still shaking" (same content as sense1 example), then generalizes to body. Also the synonyms "agitate" align with force/movement. Since definitions are schematic, the examples should weigh heavily: sense1 has progressive "My hands were shaking" matching. So choose index 1.

But I must be careful: If the correct answer were 2, I'd be wrong. Let's do deeper lexical semantics.

"Shake" with body shaking due to stress: If you look up "My hands were shaking" meaning nervousness in a thesaurus, primary sense is "tremble/shiver/shudder/didder". In WordNet, sense 2 of "shake" likely groups these. The example "My hands were shaking" in sense1 may refer to an actual earthquake physically moving hands, not nervousness. Wait sense 1 examples: "The chemist shook the flask vigorously; My hands were shaking". They are paired to show transitive and intransitive forms of same sense. Here "My hands were shaking" could be due to cold, fear, or just unrestrained. It doesn't specify. Sense 2 example "his hands shook" also doesn't specify. So identical.

Let's see if in WordNet sense 1 has hyponym `rattle` etc. and sense 2 has synonyms `shiver`, `shudder`, `didder`. Since those hyponyms indicate a subclass of shaking (from cold/fear), the synset itself ('move with or as if with a tremor') is the broader category that includes shiver/shudder. "Tremor" suggests involuntary, repeated small movements. Body shaking due to stress is a tremor. Thus sense2. In contrast, sense1 "move or cause to move back and forth" might include larger deliberate movements like shaking a bottle, head, salt shaker (not in sense1? sense8), etc. It might not specifically imply small involuntary tremor. However its example "My hands were shaking" is generic oscillation.

For fine-grained WSD, in a sentence where the body shakes due to stress/nervousness, the correct sense is likely 'tremble' class (sense2) because there is a more specific sense available. But is there a more specific sense 9? "shake (body part) to communicate a greeting..." no. Sense 2 is the appropriate specific intransitive.

The preceding "My back is still in knots" is definitely stress. "My hands are still shaking" likely stress. The target "my body shaking" is the same cause (overreaction to aftershocks). Therefore the best sense is sense 2: move with or as if with a tremor.

But definition "move with or as if with a tremor" - is a tremor (like Parkinson's) constant small rhythmic. Nervous shaking of hands after a fright may be called trembling/tremor. Yes.

However, note this text describes actual physical aftershocks. "I have felt many aftershocks. My back is still in knots..." Could be the shaking is physiological, not just hands. "My back in knots" is tension. "My hands still shaking" is part of panic response. Trembling. So sense 2.

But then the phrase "aftershocks might just be my body shaking" maybe they felt the ground shake when it was actually their body. That is their body trembling. The cause is internal physiological arousal, not external seismic. Therefore tremor.

Alternatively, the author might mean their body was physically being shaken by the aftershocks. In that case, "body shaking" = being moved back and forth by aftershocks (sense 1). But the phrase "just be my body <t>shaking</t>" after "I have felt many aftershocks" suggests: some 'aftershocks' are actually body. The body is shaking, not the ground. That's a trembling body. The body is the agent? No, body moves involuntarily. It is trembling.

Which sense handles involuntary body trembling? Candidate 2. Candidate 1 might also but it includes cause to move, and the examples are more about physical shaking (of a flask/hands). Since fine-grained, choose specific.

Let's look at the broad definition of sense1 vs sense2 again:
1. "move or cause to move back and forth" - This is ambiguous: a) intransitive subject (hands) moves back and forth; b) transitive agent moves object. It seems to emphasize repeated back-and-forth motion (one-dimension). Could be external force.
2. "move with or as if with a tremor" - A tremor is an involuntary quivering or shaking, e.g., from cold/fear/disease. This specifically fits someone in post-earthquake shock.

The synonym for sense1 given is "agitate". "Agitate" when used literally means to shake/stir up; not relevant to body. "Agitate" when mentally means disturb. That suggests sense1 may not fit body shaking due to stress (which would be mental agitation? no). The synonym for sense2 is "didder" = tremble due to cold/fear/excitement. The context is "horrible smell of gas", fire, aftershocks, back in knots: all distressing, fear, panic. So sense2 matches.

The first instance "My hands are still shaking" in this distressing context leans to sense2. But it also might literally be aftershocks moving hands. How to know? If the writer was currently experiencing aftershocks, "my hands are still shaking" could be due to ground. But then "my back is still in knots" is irrelevant to ground. Tension not ground. So the bodily reactions are internal stress. Thus sense2.

Now ensure output only JSON. The question asks return only JSON exactly like {"sense_index": 3}. So final should be {"sense_index": 2} if choosing sense 2, or {"sense_index" if sense 1}. Need final decide.

Let's see if any possibility of sense 9: "shake a body part to communicate a greeting, feeling, or cognitive state; examples: shake one's head; She shook her finger at the naughty students". Here "my body shaking" is not a deliberate body-part action for communication. So not.

Sense8: bring to a specified condition by or as if by shaking; example He was shaken from his dreams; body being shaken? "He was shaken from his dreams" means shaking someone awake. Not body shaking due to fear. "shake the salt..." no.

Sense6: stir the feelings; examples These stories shook the country. Not here.

So 2 beats 1.

Wait, but target says "aftershocks might just be my body shaking". This could be parsed as "a few of the aftershocks might just be [my body shaking]"; the gerund is an event. The event of the body "move or cause to move back and forth" maybe used because the body is an inanimate objectsubject. But if the body subject literally moves due to aftershocks? But they were actual aftershocks? If they are "actually my body shaking", the event is the body quivering. The verb's subject (body) is the thing doing the quivering. Sense2's definition "move with or as if with a tremor" has subject moving; fine.

Now, if we recall WordNet's sense 2 of shake is actually "didder; shiver; shudder" but the provided definition says "move with or as if with a tremor" synonyms=didder. This is exactly a "tremor" of hands/body. The previous instance "my hands are still shaking" can also be "shaking" as sense 1? If fine-grained WSD wants highest sense, and many corpora might mark literal shaking of body after trauma as sense1? Hmm.

Let's examine the order sense indices. The numbers assigned may correspond to wordnet instances: sense1 is `shake.v.1`, sense2 `shake.v.2`. In WordNet, `shake.v.1` frequency tag (3) and `shake.v.2` frequency tag (3?) Both common. Which is more common? Not helpful.

Maybe we can infer from hypernym hierarchy by lexical file numbers: sense1 is 2:38:00 (verb.contact? or verb.motion) and sense2 2:29:00 (verb.body? or verb.emotion?) Let's see lexical file 29 maybe "verb.perception"? I need accurate mapping to decide if sense2 relates to body-states. WordNet verb file numbers:
- 13: verb.competition
- 15: verb.contact? Actually 15 might be verb.contact
- 17: verb.change? no
- 18: verb.communication?
- 19: verb.competition? Hmm.

Let me reconstruct: WN verb lexicographer files (old numbers):
01 = A:#Not
11 = verb.body
13 = verb.change? I'm not sure.
I think I cannot rely on file numbers.

Maybe we can use examples: sense4 examples "the tall building swayed". They present candidates 1-9 in probably wordnet order but not exactly: after sense1 (2:38:00) sense2 (2:29:00) then sense3 (2:38:01) sense4 (2:38:02) sense5 (2:30:00) etc. So official WordNet order may be: shake.v.01 = 2:29? Wait PWN lines in data file: The first sense might be `%2:29:00` not `%2:38:00`. Actually the order in input might not reflect wordnet order. They list sense_key starting with 2:38:00 likely because common sense first? Hmm.

Let's search from internal knowledge: WordNet 3.1 release for verb "shake" (raw entries maybe):

sense 1:
word: shake
lexical_id: 1
synset: shake%2:29:00 (verb.perception?) definition: move or cause to move back and forth
sense 2: shake%2:38:00 (verb.contact?) move with or as if with a tremor
...

But the problem's first sense key = shake%2:38:00; second = shake%2:29:00. That suggests the ordering has been shuffled by user? Actually they are candidates listed as 1..9, but keys could be not sorted. The first candidate key 2:38:00 might correspond to WordNet sense 01. WordNet ID: In PWN 3.0, `shake.v.01` sense key `%2:29:00`? or `%2:38:00`? Let's check by memory of verb file numbers:
- WordNet verb file 09? no.
- `undergo` maybe 42?
- `move` verbs like "shake" likely in file 38 (verb.motion) or 29 (verb.contact?). "Contact" includes touch; "motion" includes move. Example "My hands were shaking" involves motion, so file 38. Sense1 `%2:38:00`. That matches. So sense1 is motion (move back and forth).
- Sense2 `%2:29:00`: file 29 maybe "verb.emotion"? Actually 29 = verb.weather? Let's see: "drizzle" file? It includes verbs of emitting light/sound maybe? Hmm.
Maybe file 29 is "verb.competition"? No.

Let's try actual WordNet file number mapping for verbs (from Wikipedia):
1 = verb.body, 2 = verb.change, 3 = verb.cognition, 4 = verb.communication, 5 = verb.competition, 6 = verb.consumption, 7 = verb.contact, 8 = verb.creation, 9 = verb.emotion, 10 = verb.motion? Wait these are file IDs? Actually WN lex files have two-digit numbers: 00, 01-44. There's mapping 11 = verb.body, 13 = verb.change, 15 = verb.contact, 17 = verb.communication, 19 = verb.competition? But I recall noun file IDs like 01=body, 04=animal, etc. For verbs: 11=body, 13=change, 15=contact, 17=communication, 19=competition, 21=consumption, 24=contact? no.

Hmm. The second digit after `%2` is file number within POS. For verbs files:
11 verb.body
13 verb.change
15 verb.contact
17 verb.communication
19 verb.competition
21 verb.consumption
24 verb.contact? Wait.
25 verb.cognition?
27 verb.communication?
28 verb.competition?
29 verb.creation?
30 verb.emotion?
31 verb.contact?
32 verb.motion?
34 verb.perception?
35 verb.contact?
36 verb.competition?
37 verb.stative?
38 verb.motion?
...

I'm not precise. But `%2:29` might be verb.contact? Didder might be body contact? Not helpful.

However, note sense3 and sense4 also 2:38 (motion). sense2 is 2:29 maybe verb.contact? "didder" maybe contact?

Given direct example mapping, sense1 is likely annotated. The instructions say "Do not hedge. Choose single best indexed sense." My decision should maximize fit.

Let's maybe consider sense1 vs sense2 from WSD official answers in a human-labeled corpus. If I can guess humans would choose sense 2 because of the emotional/earthquake context of trembling. But would they? For sentence "My hands were shaking", if nervousness, label "shake.v.02 (tremble)"? If due to earthquake vibration, label "shake.v.01 (move back and forth)"? Hmm. Since the sentence says cause unknown ("might just be my body shaking") it could be either. But in context, they mention "back in knots" stress, suggesting own body nervous trembling. Human annotator might choose the more general sense? Let's consider the OntoNotes/FrameNet mapping: In FrameNet, "shake" verb in the context of hands/ground has frame "Change_position_on_a_scale"? No, "Cause_to_move_in_place" vs "Moving_in_place"? "Trembling" is a different frame "Body_movement"? "My hands were shaking" due to nerves could be "Trembling" frame. WN sense2 corresponds to that.

But the task not FrameNet; choose WordNet senses. Fine-grained. The synonyms should help: "didder" is a more fitting synonym for nervous body vibration than "agitate". The examples for sense2 are "his hands shook", which fits "my hands are still shaking" (same content). The context of "aftershocks" as a possible excuse for body shaking due to stress: Trembling/didder. The best indexed sense is 2.

But wait, the definition of sense1 uses example "My hands were shaking" — if they intended the WordNet sense of "My hands were shaking" to be sense1, then annotation for these instances would be sense1. So if using examples as gold, sense1. Why would WordNet include same example in sense1 if sense2 is more appropriate? It shows sense1 covers intransitive "hands shaking" and transitive "shake flask". It seems WordNet uses "My hands were shaking" as indicative of the most basic sense. The phrase "his hands shook" in sense2 might be due to some aspect not clear (maybe impersonal 'tremble'?). The user of WSD, however, should not override WordNet's own sense assignment if available. They gave examples as part of sense; if sense1 explicitly includes same phrase, that is a strong tie. But what about sense3 "shake or vibrate rapidly and intensively (judder)". Examples: old engine juddering. Body aftershocks rapidly? Could be. But body isn't engine. Not best.

The task likely expects us to use the sentence context plus examples/synonyms to determine. If both senses include hands shaking examples, synonyms decide. Synonyms: sense1 = agitate, sense2 = didder. The context of stress aligns with didder. But maybe agitate (in the mental sense) also aligns with stress? Wait sense1 synonym "agitate" includes mental disturb: "The bad news agitated him". That is cause to move back and forth? Actually "shake" can mean "upset, agitate (emotionally": 'He was badly shaken by the news' is sense6? Wait "agitate" as synonym sense1 is physical? Actually agitate v. = move or cause to move with violence, or to disturb. The mental sense is a different verb. But given context stress, "agitate" could be a near-synonym for emotions. Hmm no.

Let's also consider candidate 6: "stir the feelings, emotions, or peace of" synonyms stimulate, excite, stir, examples These stories shook the community. This is the emotional/mental "I was shaken" but not for body shaking. "My body shaking" literally not "the community". Not.

Candidate 5 "undermine or cause to waver" examples faith/hopes shaken; bad news shook hopes. Also emotional. Not.

Synonyms are not strict WordNet synonyms but a provided set. "agitate" given for sense1 maybe comes from user, not WordNet. Could just be hint. They might have selected synonyms to help disambiguate.

What about gloss difference: "move or cause to move back and forth" vs "move with or as if with a tremor". If the subject is an inanimate object like a flask, sense1. If subject is body/hands, sense2. The phrase "my body shaking" subject body, fits sense2. Because "tremor" is involuntary shaking. Also the examples for sense2 > "his hands shook" (hands body part) while sense1 example includes "The chemist shook the flask" (transitive, inanimate) and "My hands were shaking" (body part). But the second example in sense1 might also refer to shaking hands like flasks, not necessarily nervousness.

Actually WordNet uses one example pair to illustrate sense1's causative/inchoative alternation. It is not specifically body part/nervous. The second example includes "My hands were shaking" perhaps to show intransitive. It might not represent a tremor. Yet real usage of "My hands were shaking" frequently means nervous. Hmm.

Maybe the answer is 1 because the target phrase "my body shaking" is parallel to "the ground/bridge/building shaking" (caused by aftershocks). The body is being "moved or caused to move back and forth" by the aftershocks. In a phrase "few of the aftershocks might just be my body shaking", the aftershocks are experiences of shaking; the body is the thing moving. The sense of "building/ground shaking" is usually sense1 (move or cause to move back and forth) maybe sense4 (rock/sway). For body, sense1. The emotional/str component is secondary; the phrase is literally body in motion. I think final answer likely 1, but I'm now less sure.

Let's reread surrounding: "I decided to brave the storm. There was a horrible smell ... fire ... I have felt many aftershocks. My back is still in knots and my hands are still shaking. I think a few of the aftershocks might just be my body <t>shaking</t>." There are actual aftershocks (earthquake). They explicitly say they have felt many aftershocks. Their hands were shaking. They suspect some aftershocks may actually be their body. So the target refers to the possibility that the perceived shakes are just their own body shaking. The body is shaking in a way that mimics an aftershock — i.e., moving back and forth. This is literal physical movement. That's sense1 maybe. But also it could be trembling. The text doesn't say "from fear" but the back in knots suggests tension.

Let's see if "hands are still shaking" is intransitive literal caused by lingering small quakes or by nervousness. At that moment, aftershocks were real and ongoing. The writer has felt many aftershocks, so their body may have been jolted. They think some aftershocks may just be body. The body shaking could actually be from aftershocks (external) or internal. If the body itself is moving, it is because of a tremor (sense2) or because it's being jostled (sense1). If internal, you'd call it trembling. If external, ground causing back-and-forth movement = sense1 (or 4). Since they compare it to an aftershock (ground moving), they'd conceptualize it as body moving back and forth (sense1). So sense1 seems apt because it's the same generic movement as an earthquake.

When someone says "I can't stop shaking" after a traumatic event, dictionary: "tremble, quiver; to shake or move with a slight trembling motion". WordNet sense2. So I lean 2.

However, the target is "body shaking" not "I am shaking". If someone says "my body is shaking", that may sound clinical, like actual body moving. Could be either.

Potential constraint: WSD tasks often choose the most common sense if ambiguous. Most common sense for "shake" is primary sense1 (move/caused move). So probably answer 1.

But the instructions explicitly say use context and examples. This is not to default to most common; fine-grained.

Let's decide by examining the definition's genus words and whether superordinate or subordinate specific. Sense1 definition: "move or cause to move back and forth." It is coherent with "my body shaking" as movement. Sense2: "move with or as if with a tremor." This is a special kind oflove; if body shakes due to tension, it is a tremor. There is a more specific applicable sense (2). In WSD, choose the subordinate sense if context supports. The context of "back in knots", "horrible smell", "fire", "aftershocks", supports involuntary trembling. So index 2.

But there is also possible sense with external cause: aftershocks (earthquake) literally cause the body to move. But person says body shaking could *be* aftershocks. It can be both. Which interpretation is more plausible in a first-person earthquake account? The physical risk and trauma cause nervous trembling; attributing aftershocks to own body is a known phenomenon: earthquake survivors feel phantom aftershocks from their own trembling. That is body trembling. Yes phantom aftershocks are often due to one's own body shaking from anxiety. That fits sense2.

Hence I'll choose index 2.

Wait but I need to be careful to output only JSON. No explanation. So final answer {"sense_index": 2}. I should be confident. Let me finalize.

Before final, consider one more nuance: WordNet sense 2's examples: "his hands shook" likely past not progressive. The target is present participle gerund in a NP. WSD doesn't consider tense necessarily, but a gerund as a noun-ish event can map to sense1 if generic action. Hmm.

The candidate example for sense1 uses "My hands were shaking" progressive, matching "shaking" surface. Candidate 2 uses "shook" past, matching "shake" not "shaking". Since we choose by meaning not form but surface form could help. The user prompt: target surface form shaking. The task includes last token <t>shaking</t>. There is also earlier "shaking" not target. The examples in candidate1 include "My hands were shaking" same surface. Candidate2 includes "his hands shook" different inflection. Might indicate grouping by surface form for sense1. However this is superficial; tense doesn't determine sense. But yes.

Also phrase "my body shaking" can be seen as "my body is in the state of shaking". A body can "shake" due to being cold/fear (tremble). If you say "My body was shaking from the cold", you'd use sense2 didder. If you say "My body was shaking during the earthquake", it could be sense1 (earthquake moved body) or sense2 (fear). In this context, both cold/fear and earthquake. Fine-grained could go 2.

Need decide final. I think sense 2 is a safer answer because it's more specific and the examples/synonyms line up: "didder" implies trembling; his hands shook. The context of the person's body trembling from anxiety after aftershocks fits a tremor. Also the note "My back in knots" (physiological stress) supports. So 2.

But if this is from a WSD dataset like Senseval for "shake" maybe the gold label for "body shaking" might be 1 due to being literal physical movement. How would I know? Let me try to think of possible official answer. If I were annotating WordNet: The phrase "my body shaking" refers to dynamic physical movement, not specifically tremor. WordNet definitions: sense1 = "move or cause to move back and forth". Since body is moving with short, quick, irregular movements? Hmm. "Tremor" is irregular but small. Which gloss covers "body shaking due to cold"? In dictionaries, that is one sub-sense of "shake" (v.i.): "to move or sway with short, quick, irregular vibrations from weakness, fear, or cold" (specific). WordNet has separate sense for that? Probably sense2. So if dictionary sub-sense maps to WN sense2, then body from stress = sense2.

However, in WordNet the example for sense1 includes "My hands were shaking" which is the same phrase as in our context. If WN places that exact phrase under sense1, a test using that example would expect sense1. But dictionary sub-sense might be collapsed into sense1 with generic examples. Hmm. The user candidate gloss gives sense1 examples "The chemist shook the flask vigorously; My hands were shaking". If I'm using examples together, I see "My hands were shaking" in sense1 and "his hands shook" in sense2. If I perceive the target as basically same as first example, I'd choose 1. But if I think the specific cause (fear/stress) makes it a tremor, I'd choose 2.

Which one would a linguist performing fine-grained WSD choose? They would consider semantic domain (animate body+involuntary trembling vs. object+move). The phrase "my body shaking" is an animate part (whole body) + involuntary due to stress. The synset with synonyms "didder" and definition "move with or as if with a tremor" specifically means body trembling. So 2.

I decide index 2.

One final consideration: The instruction says "WordNet glosses are schematic. Use the sentence context, the examples, and the synonyms to choose the best indexed sense. Do not hedge. Choose the single best indexed sense." We need return JSON exactly. I will answer {"sense_index":2}.

 The user wants me to perform Word Sense Disambiguation on the target word "see" in the given context.

Context: "I could see the flames from San Francisco from my house across the bay."

The sentence describes a visual perception: the speaker could perceive flames (from San Francisco) visually from their house across the bay.

Let me look at the candidate senses:

1. sense_key=see%2:39:00:: - "perceive by sight or have the power to perceive by sight" - examples mention seeing details, seeing a bird in a tree. This fits visual perception of flames.

2. sense_key=see%2:31:01:: - "perceive (an idea or situation) mentally" - This is mental understanding, like "Now I see!" Not visual.

3. sense_key=see%2:39:02:: - "perceive or be contemporaneous with" - synonyms: witness, find. Example "We found Republicans winning the offices." This implies witnessing an event, but the context is simply visual perception.

4. sense_key=see%2:36:00:: - "imagine; conceive of; see in one's mind" - Not visual actual perception.

5. sense_key=see%2:31:00:: - "deem to be" - consider, regard. Not fitting.

6. sense_key=see%2:31:02:: - "get to know or become aware of" - Usually accidentally. Example "I see that you have been promoted" - becoming aware through information. Not visual.

7. sense_key=see%2:39:03:: - "see or watch" - synonyms watch, view, catch, take in. Examples: view a show on television. This is more active watching, not just perceive by sight.

8. sense_key=see%2:38:00:: - "come together" - meet. Not fitting.

9-24: Various other meanings (find out, be careful, visit, date, receive, deliberate, examine, experience, escort, match, interpret). None fit as well as sense 1.

The best sense is 1: "perceive by sight or have the power to perceive by sight". The speaker physically perceives the flames with their eyes from across the bay.

I should return only JSON object exactly like {"sense_index": 3}, but with index 1.

The user wants me to perform Word Sense Disambiguation for the word "house" in a specific context. I need to analyze the context and choose the best sense from the given candidates.

Context: "I could see the flames from San Francisco from my <t>house</t> across the bay."

The speaker is talking about seeing flames from San Francisco from their "house across the bay." This clearly refers to a physical dwelling/residence where someone lives.

Looking at the candidate senses:
1. sense_key=house%1:06:00:: | definition=a dwelling that serves as living quarters for one or more families — This is the physical house where someone lives.
2. business organization — no
3. religious community — no
4. theatre audience — no
5. legislative assembly — no
6. aristocratic family line — no
7. children playing house — no
8. astrology house — no
9. gambling house management — no
10. social unit living together (family/household) — This is about people, not the physical building.
11. theatre building — no
12. a building in which something is sheltered or located — This is more general, like "carriage house."

The context "my house across the bay" refers to the speaker's dwelling/residence. The phrase "from my house across the bay" indicates a physical location/building where the speaker lives.

Sense 1 is the best fit: "a dwelling that serves as living quarters for one or more families." This is the prototypical sense of "house" as a place where someone lives.

Sense 10 (social unit living together) could potentially be ambiguous, but "from my house across the bay" spatially locates the speaker at a building/place, not a family unit. Also, "my house" with the physical location "across the bay" strongly suggests the physical dwelling.

Sense 12 is too general and refers to buildings sheltering things, not residences.

Sense 1 is the correct answer.

reasoning_content:
Let me analyze the context carefully.

The context is about someone across from San Francisco seeing flames. San Francisco is a city located on the San Francisco Bay. The sentence says "from my house across the bay" - this refers to a body of water separating the speaker's house from San Francisco.

Looking at the candidate senses:
1. bay = an indentation of a shoreline larger than a cove but smaller than a gulf - this is the geographic body of water sense. This fits "San Francisco Bay" perfectly.
2. sound of a hound - doesn't fit
3. Mediterranean evergreen tree (laurel) - doesn't fit
4. compartment on a ship - doesn't fit
5. compartment in aircraft - doesn't fit
6. small recess opening off larger room - doesn't fit
7. horse color - doesn't fit

The context clearly refers to the San Francisco Bay, which is a body of water - an indentation of a shoreline. This is sense 1 (bay%1:17:00::).

The instruction says return only JSON exactly like {"sense_index": 3}. But I need to choose the correct index. Let me map the candidate senses to their listed indexes. The candidates are numbered 1-7, and I should use the number shown in the candidate list.

The correct sense is candidate #1: bay%1:17:00:: - an indentation of a shoreline.

So I should return {"sense_index":1}.

reasoning_content:
The user wants me to perform Word Sense Disambiguation for the word "believe" in context.

Context: "It's hard to believe this really is happening."

The target is "believe" as in "It's hard to believe this really is happening."

Let me analyze the candidate senses:

1. accept as true; take to be true - examples: "I believed his report; We didn't believe his stories from the War"
2. judge or regard; look upon; judge - synonyms: think, consider, conceive - examples: "I think he is very smart; I believe her to be very smart"
3. be confident about something - synonyms: trust - examples: "I believe that he will come back from the war"
4. follow a credo; have a faith; be a believer - examples: "When you hear his sermons, you will be able to believe, too"
5. credit with veracity - examples: "You cannot believe this man; Should we believe a publication like the National Enquirer?"

In the context "It's hard to believe this really is happening", the speaker is finding it difficult to accept that the event (seeing flames from San Francisco across the bay, aftershocks) is actually happening. The phrase "believe this really is happening" means accepting as true/real that the events are occurring.

This most closely matches sense 1: accept as true; take to be true.

However, sense 5 "credit with veracity" is about believing a person/source. Here the object is "this really is happening" - a proposition/clause, not a person/source.

Sense 2 is about judging/regarding, like "I believe her to be very smart" - an evaluation/opinion about someone.

Sense 3 is about being confident that something will happen - "I believe that he will come back from the war."

Sense 4 is religious faith.

The example for sense 1 "I believed his report" - accepting something as true. "It's hard to believe this really is happening" is about accepting the proposition "this really is happening" as true.

So sense 1 is the best fit.

Wait, let me reconsider. "believe this really is happening" - "believe" here takes a clause. Sense 1 examples take objects (his report, his stories). But the gloss "accept as true; take to be true" can apply to propositions/clauses too.

Sense 5's examples are about believing a person/publication. The target context has "this" as a clause/proposition, not a person.

Actually, in WSD, "believe" in "believe X is Y" or "believe that S" can sometimes be sense 2 (think/judge) or sense 1 or 3 or 5 depending on meaning.

Here "It's hard to believe this really is happening" - this is an expression of difficulty accepting reality. The speaker is witnessing something shocking (flames from San Francisco across the bay during aftershocks). "Hard to believe" = hard to accept as true/real.

This is definitely sense 1: accept as true; take to be true.

Sense 5 "credit with veracity" is close but specifically about believing/trusting a person or source's truthfulness. The National Enquirer example is about whether to believe what a publication says. The target is "this really is happening" not a person/source.

I'll go with sense1.

4. happen%2:30:01:: come into being; become reality; materialize. Could be 'this is really happening' meaning becoming reality. But sense 1 'come to pass' better for an event currently happening. WordNet 'come to pass' includes ongoing? Example 'What is happening?' directly. This fits.
5. happen%2:40:12:: come upon; not here.
Thus index 1. Need return JSON {"sense_index": 1}. Ensure no hedging.

We need choose single best indexed sense among 11. Need return JSON object {"sense_index": <number>}. Do not answer with sense key. Use context. Let's analyze.

Candidate senses:

1. corner%1:15:02:: a place off to the side of an area. examples: rightfield corner, southeastern corner of the Mediterranean. Geographic area side, not building intersection.
2. corner%1:15:00:: point where two lines meet or intersect; examples corners of a rectangle.
3. corner%1:06:02:: interior angle formed by two meeting walls; synonyms=nook; examples a piano was in one corner of the room. Indoor corner.
4. corner%1:06:00:: intersection of two streets; synonyms street corner, turning point; examples standing on the corner. Building on the corner likely means building located at the intersection of two streets. That fits "Building on the corner severely damaged". It is a building positioned at a street corner. So best sense index 4.
5. point where three areas meet (cube corner).
6. small concavity.
7. monopoly.
8. predicament.
9. projecting part where two sides/edges meet (physical object).
10. remote area.
11. architecture solid exterior angle.

The phrase "Building on the corner" strongly indicates a building at the intersection of two streets. That matches sense 4. Could sense 11? "Building on the corner" as exterior angle? Possibly but "solid exterior angle of a building; especially one formed by a cornerstone" is architectural quoin. That seems not used in common phrase. "Building on the corner" means located at the street corner. So index 4.

Need output only JSON. Ensure exact.

It clearly means an elderly woman, having lived a relatively long time. The construction "an old lady" is a person. The definition sense 1 = (used especially of persons) having lived for a relatively long time or attained a specific age. Example: "his mother is very old; a ripe old age". Yes. Sense 2 is long duration; not new (object). Sense 4 experienced. The "old lady" could be wife? No. It refers to age. The other "very old mother" confirms age. Therefore index 1. Need return exactly JSON object {"sense_index": 1}. Ensure no other text.

The user wants me to perform WSD for the word "lady" in a given context.

Context: "Building on the corner severely damaged, so an old lady and her very old mother are in the guest room."

Candidate senses:
1. lady%1:18:02:: | definition=a polite name for any woman | examples="a nice lady at the library helped me"
2. lady%1:18:01:: | definition=a woman of refinement | synonyms=dame, madam, ma'am, gentlewoman | examples="a chauffeur opened the door of the limousine for the grand lady"
3. lady%1:18:00:: | definition=a woman of the peerage in Britain | synonyms=noblewoman, peeress

Analyzing the context: "an old lady and her very old mother" - this is referring to an elderly woman and her mother. There's no indication she's of refinement or nobility. The phrase "old lady" commonly refers to an elderly woman in a general, polite sense. This matches sense 1: "a polite name for any woman" with the example "a nice lady at the library helped me."

Sense 2 (woman of refinement) would imply some social refinement, not typically used in the colloquial "old lady" referring to an elderly woman displaced by a disaster. Sense 3 (peerage/ noblewoman) is clearly inapplicable as there's no indication of British nobility.

The best answer is sense 1.
