Target lemma: find
Target surface form: found
Context:
He theorized that in the eye cancer, an infant inherited a damaged copy of a gene from one parent and a normal copy from the other. The tumor, he suggested, developed when the second, normal copy also was damaged. But there was no way to prove Dr. Knudson's "two-hit "theory. Back then, scientists had no way of ferreting out specific genes, but under a microscope they could see the 23 pairs of chromosomes in the cells that contain the genes. Occasionally, gross chromosome damage was visible. Dr. Knudson <t>found</t> that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease. Under a microscope he could actually see that a bit of chromosome 13 was missing.

The user wants me to perform Word Sense Disambiguation for the target word "found" (lemma "find") in the given context.

Let me analyze the context carefully:

"Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease. Under a microscope he could actually see that a bit of chromosome 13 was missing."

So Dr. Knudson discovered or determined through investigation/study that some children had inherited a damaged copy of chromosome No. 13. This was a scientific finding based on research and observation.

Let me look at the candidate senses:

1. find%2:40:02:: - come upon, as if by accident; meet with (happen, chance, bump, encounter)
   - This implies accidental discovery. While scientific discoveries can sometimes be accidental, the context suggests systematic research. The examples "We find this idea in Plato" suggests encountering something existing, not discovering a new fact through investigation.

2. find%2:39:02:: - discover or determine the existence, presence, or fact of (detect, observe, discover, notice)
   - Examples: "She detected high levels of lead", "We found traces of lead"
   - This is about detecting or noticing something physically present. While he did observe under a microscope, the "found that..." introduces a clause about an inherited pattern, not just detecting physical presence.

3. find%2:40:00:: - come upon after searching; find the location of something that was missed or lost
   - Physical searching for an object. Not applicable here.

4. find%2:32:00:: - establish after a calculation, investigation, experiment, survey, or study (determine, find out, ascertain)
   - Examples: "find the product of two numbers", "The physicist who found the elusive particle won the Nobel Prize"
   - This seems very relevant. Dr. Knudson established through investigation/study that children had inherited the damaged chromosome.

5. find%2:31:10:: - come to believe on the basis of emotion, intuitions, or indefinite grounds (feel)
   - Not applicable. This was based on scientific observation, not emotion/intuition.

6. find%2:39:01:: - perceive or be contemporaneous with (witness, see)
   - "We found Republicans winning the offices" - this is about witnessing events. Not quite right.

7. find%2:40:01:: - get something or somebody for a specific purpose
   - Not applicable.

8. find%2:36:00:: - make a discovery, make a new finding (discover)
   - Examples: "Roentgen discovered X-rays", "Physicists believe they found a new elementary particle"
   - This is about making a scientific discovery. Very relevant.

9. find%2:31:09:: - make a discovery (discover)
   - Examples: "She found that he had lied to her", "The story is false, so far as I can discover"
   - This is about discovering a fact, often through investigation or being told.

10. find%2:40:03:: - obtain through effort or management
    - Not applicable.

11. find%2:32:01:: - decide on and make a declaration about (rule)
    - Legal context. Not applicable.

12. find%2:30:00:: - receive a specified treatment (abstract)
    - Not applicable.

13. find%2:39:05:: - perceive oneself to be in a certain condition or place
    - Not applicable.

14. find%2:40:15:: - get or find back; recover the use of
    - Not applicable.

15. find%2:38:10:: - succeed in reaching; arrive at
    - Not applicable.

16. find%2:30:13:: - accept and make use of one's personality, abilities, and situation
    - Not applicable.

Now I need to decide between sense 4, 8, 9, and possibly 2.

Sense 4: establish after a calculation, investigation, experiment, survey, or study
Sense 8: make a discovery, make a new finding
Sense 9: make a discovery (She found that he had lied to her)
Sense 2: discover or determine the existence, presence, or fact of

Let me look more carefully at the distinctions.

Sense 8 (find%2:36:00::): "make a discovery, make a new finding" - synonyms: discover. Examples: "Roentgen discovered X-rays", "Physicists believe they found a new elementary particle". This seems to be about discovering something new in the world, a new phenomenon or particle.

Sense 9 (find%2:31:09::): "make a discovery" - synonyms: discover. Examples: "She found that he had lied to her", "The story is false, so far as I can discover". This seems to be about discovering a fact, often something already true but not known to the subject.

Sense 4 (find%2:32:00::): "establish after a calculation, investigation, experiment, survey, or study" - synonyms: determine, find out, ascertain. Examples: "find the product of two numbers", "The physicist who found the elusive particle won the Nobel Prize".

Wait, the example for sense 4 includes "The physicist who found the elusive particle won the Nobel Prize" - this is very similar to our context about Dr. Knudson finding something about chromosome 13.

But sense 8 also has "Physicists believe they found a new elementary particle".

Let me think about the subtle differences. Sense 4 emphasizes the process of establishing something through systematic investigation (calculation, experiment, study). Sense 8 emphasizes the act of making a discovery - bringing to light something new.

In the context, Dr. Knudson was working on a theory and found that some children had inherited a damaged chromosome. This was a scientific finding based on looking at chromosomes under a microscope. It was a discovery (sense 8) but also an establishment through investigation (sense 4).

However, looking at the examples for sense 9: "She found that he had lied to her" - this is very close to "Dr. Knudson found that some children... had inherited..." Syntactically, "found that + clause" often maps to sense 9.

But wait, let me look at sense 2 again: "discover or determine the existence, presence, or fact of" - examples: "She detected high levels of lead", "We found traces of lead". This is more about detecting physical substances or direct evidence. But our sentence has "found that..." introducing a proposition, not just "found traces of chromosome damage."

Actually, looking at the context again: "Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13..." This is a "find that" construction with a clause.

In WordNet, "find that" constructions often map to sense 9 (find%2:31:09::) or sense 4 (find%2:32:00::).

But let me reconsider sense 4 vs sense 8 vs sense 9.

Sense 4: establish after a calculation, investigation, experiment, survey, or study
- This is about determining/ascertaining facts through systematic methods.
- Example: "The physicist who found the elusive particle..."

Sense 8: make a discovery, make a new finding
- This is about discovering something new.
- Example: "Roentgen discovered X-rays"

Sense 9: make a discovery
- Example: "She found that he had lied to her"

The context describes Dr. Knudson doing scientific research. He was investigating eye cancer and chromosomes. He established through his research that some children had inherited the damaged chromosome. This seems like sense 4 or sense 8.

But looking at the specific content: This was a discovery about the genetic basis of retinoblastoma (eye cancer). It was a new finding. However, the sentence emphasizes that he determined this through observation under a microscope.

Let me look at the exact wording of sense 2 again: "discover or determine the existence, presence, or fact of". The fact that children had inherited a damaged copy... this is determining a fact.

Actually, I should look at how these senses are typically distinguished in WordNet.

Sense 2 (find%2:39:02::) is in the perception/verb.cognition category? Let me check the lexicographer file. The sense key find%2:39:02:: - the "39" indicates verb.perception. So this is about perceiving/detecting with senses or instruments.

Sense 4 (find%2:32:00::) - "32" indicates verb.cognition. This is about cognitive acts: establish after calculation, investigation, etc.

Sense 8 (find%2:36:00::) - "36" indicates verb.creation? No, 36 might be verb.cognition or another category. Actually, in WordNet, 40=verb.contact, 31=verb.cognition, 32=verb.cognition, 39=verb.perception, 36=verb.cognition? Let me recall: WordNet lexicographer file numbers:
- 29: verb.body
- 30: verb.change
- 31: verb.cognition
- 32: verb.cognition? No, 31 and 32 are both verb.cognition? Actually:
  - 31: verb.cognition (know, think, believe)
  - 32: verb.cognition (calculate, reason, estimate)
  - 36: verb.creation (create, make)
  - 39: verb.perception (see, hear, feel)
  - 40: verb.contact (touch, hit, find physical)

Wait, sense 8 is find%2:36:00:: which would be verb.creation? That doesn't seem right for "discover". Let me reconsider. Actually, "make a discovery" might be in verb.creation because you're creating new knowledge? Or maybe 36 is verb.cognition too? No, I think 36 might be verb.social or something else. Actually, looking at standard WordNet lexicographer files:
- verb.cognition: 31, 32
- verb.perception: 39
- verb.contact: 40
- verb.creation: 36? No, 36 is verb.cognition? Let me think... Actually, I should not rely too much on the file numbers since I might misremember them.

Let me focus on the definitions and examples.

Sense 4: "establish after a calculation, investigation, experiment, survey, or study"
- This fits very well with scientific research context.
- The example "The physicist who found the elusive particle won the Nobel Prize" is almost exactly parallel to Dr. Knudson finding the chromosome damage.

Sense 8: "make a discovery, make a new finding"
- This also fits, but the examples emphasize discovering new entities (X-rays, elementary particles) rather than establishing a specific factual relationship through investigation.

Sense 9: "make a discovery" with example "She found that he had lied to her"
- This is about discovering a fact, often through indirect means or realization.
- But in scientific contexts, sense 4 might be more precise because it emphasizes the systematic investigation aspect.

Sense 2: "discover or determine the existence, presence, or fact of"
- Examples involve detecting physical substances (lead).
- While chromosome damage is physical, the sentence says he "found that some children... had inherited..." which is more abstract than detecting physical presence.

Now, looking at the broader context: "But there was no way to prove Dr. Knudson's 'two-hit' theory. Back then, scientists had no way of ferreting out specific genes... Occasionally, gross chromosome damage was visible. Dr. Knudson found that some children... had inherited a damaged copy... Under a microscope he could actually see..."

So he was investigating, looking at chromosomes, and established/determined through this investigation that the inheritance pattern existed. This strongly suggests sense 4: "establish after a calculation, investigation, experiment, survey, or study."

However, I need to be careful. Let me look at sense 8 again. "make a discovery, make a new finding" - synonyms: discover. The example "Physicists believe they found a new elementary particle" is very similar. But "found a new elementary particle" is different from "found that some children had inherited..." The former is finding a thing; the latter is finding a fact/proposition.

Sense 9 specifically handles propositional discoveries: "She found that he had lied to her". But sense 9's definition is just "make a discovery" - it might be the "learn" sense.

Actually, in many WSD datasets, "find that + clause" in scientific contexts often maps to sense 4 or sense 9.

Let me look at the exact WordNet senses for "find" as I recall them:
- find, happen, chance, bump, encounter (come upon unexpectedly)
- find, detect, observe, discover, notice (discover or determine existence/presence/fact of)
- find, regain (come upon after searching)
- determine, find, find out, ascertain (establish after investigation)
- find, feel (come to believe)
- witness, find, see (perceive or be contemporaneous with)
- line up, get hold, come up, find (get something for a specific purpose)
- discover, find (make a discovery)
- discover, find (make a discovery - propositional?)

Wait, there are two "discover" senses in WordNet for find:
1. discover, find (make a discovery) - "She found that he had lied to her"
2. discover, find (make a discovery, make a new finding) - "Roentgen discovered X-rays"

Actually, looking at the candidate list:
8. sense_key=find%2:36:00:: | definition=make a discovery, make a new finding | synonyms=discover | examples=Roentgen discovered X-rays; Physicists believe they found a new elementary particle
9. sense_key=find%2:31:09:: | definition=make a discovery | synonyms=discover | examples=She found that he had lied to her; The story is false, so far as I can discover

Sense 9 seems to be the propositional "find that" sense. But sense 4 also often takes "that" clauses in scientific contexts.

Let me think about which sense is "single best".

The context emphasizes:
- Scientific investigation ("theorized", "prove", "scientists had no way", "under a microscope")
- Establishing a fact through observation ("Under a microscope he could actually see...")
- The result is a scientific conclusion about inheritance

Sense 4: "establish after a calculation, investigation, experiment, survey, or study" - synonyms: determine, find out, ascertain. This captures the methodological aspect.

Sense 9: "make a discovery" - but the example is interpersonal ("he had lied"). The scientific discovery sense might be 8.

Sense 8: "make a discovery, make a new finding" - but the examples are about discovering objects/entities (X-rays, particles), not establishing propositions about inheritance patterns.

Actually, looking at the example for sense 4: "The physicist who found the elusive particle won the Nobel Prize" - this is exactly the register we need. A scientist finding something through investigation.

But our target is "found that some children..." - the "that" clause. Does sense 4 take "that" clauses? Yes, "establish that..." is natural.

However, sense 9's example is literally "She found that he had lied to her". So syntactically, sense 9 is a perfect match for "found that + clause".

But semantically, is sense 9 right? Sense 9 is defined as "make a discovery" with the example about lying. In WordNet, this sense might be more about learning something surprising or previously unknown, often through being told or realizing.

Sense 2: "discover or determine the existence, presence, or fact of" - this might also take "that" clauses? "We found that traces of lead were present" - but the examples given are direct objects.

Let me reconsider sense 2. The definition says "discover or determine the existence, presence, or fact of". The fact of inheritance... "determine the fact that some children had inherited..." This could work. But the examples are about physical detection: "detected high levels of lead", "found traces of lead". The synonyms are detect, observe, discover, notice. These are more about direct sensory/instrumental detection. While Dr. Knudson did use a microscope, the "found that..." clause describes a conclusion about inheritance, not just an observation of chromosome damage. The next sentence says "Under a microscope he could actually see that a bit of chromosome 13 was missing" - that's the direct observation. The "found that..." is the broader conclusion from the investigation.

So sense 2 might be too narrow/perceptual.

Between sense 4 and sense 9:

Sense 4 is about establishing through systematic investigation. The examples include mathematical calculation and physics experiments. This is a scientist establishing a fact through research.

Sense 9 is about making a discovery, with an example of finding out someone lied. This seems more general and less specifically about systematic investigation.

Given that Dr. Knudson was conducting a scientific study, and the context mentions "theorized", "prove", "scientists", "under a microscope", sense 4 seems most appropriate because it captures the systematic establishment of a fact through investigation.

Wait, but I need to check if sense 4 is typically used with "that" clauses. "Establish after a calculation..." - yes, you establish that something is true.

Let me also consider sense 8 again. "make a discovery, make a new finding". Was this a new finding? Yes, it was a discovery about retinoblastoma. But the example "Physicists believe they found a new elementary particle" suggests finding a new entity. Our sentence is about finding a pattern/fact.

Actually, looking at WordNet 3.1 or similar, sense 8 (find%2:36:00) might be the "discover" sense that is synonymous with "detect" in a scientific context. But the candidate list shows sense 2 as the one with synonyms detect, observe, discover, notice.

Let me look at the candidate list ordering. It seems to be ordered by sense key or frequency.

I think the strongest candidates are 4 and 9. Let me see if there's any reason to prefer one over the other.

Sense 4: establish after a calculation, investigation, experiment, survey, or study
- This is very specific about the method: investigation/study.
- The context explicitly describes an investigation: looking at chromosomes, theorizing, proving.

Sense 9: make a discovery
- More general. The example is non-scientific (lying).

In WordNet, "find" sense 4 (determine, find out, ascertain) is often used for scientific findings where data leads to a conclusion. "The study found that..." is extremely common in academic English and maps to this sense.

Sense 9 is more like "I found that he's not at home" - discovering a pre-existing state.

Given the scientific context and the emphasis on investigation, sense 4 seems best.

But wait - I should double-check the exact wording. "Dr. Knudson found that some children with the eye cancer had inherited a damaged copy..."

In many lexical resources, "find that" in scientific contexts goes to the "determine/ascertain" sense (sense 4).

However, I want to make sure about sense 8. "make a discovery, make a new finding" - could this be it? The discovery was that the damaged chromosome was inherited. This was indeed a new finding. But sense 8's examples are about discovering things (X-rays, particles), not about establishing facts through data analysis.

Actually, looking at the candidate list again, I notice sense 8 and 9 both have "discover" as a synonym. But sense 8 is "make a discovery, make a new finding" while sense 9 is just "make a discovery". The distinction in WordNet is often that sense 8 (find%2:36) is for discovering something for the first time (creative discovery), while sense 9 (find%2:31) is for finding out a fact.

But sense 4 is clearly about investigation and study.

Let me think about the phrase "two-hit theory" and "prove". The text says there was no way to prove the theory, but Dr. Knudson found that children had inherited the damaged chromosome. This finding supported the theory. It was an investigative result.

I think sense 4 is the best fit.

Wait, I should also consider if sense 2 could be right. "discover or determine the existence, presence, or fact of". The "fact of" part could cover "the fact that some children had inherited...". But the examples are about physical traces, not inherited genetic patterns. And the synonyms (detect, observe, discover, notice) are more about perception than conclusion.

Actually, looking very carefully: "Under a microscope he could actually see that a bit of chromosome 13 was missing." The seeing is observation. The finding is the conclusion. So sense 2 might be too tied to direct observation/perception.

Therefore, my choice is sense 4.

But let me reconsider one more time. Is there any chance it's sense 9? "She found that he had lied to her" - this is exactly the same syntactic structure: subject + found + that-clause. And semantically, Dr. Knudson discovered a fact.

However, the instruction says to use context, examples, and synonyms together. The context is scientific investigation. The examples for sense 4 include a physicist finding a particle. The synonyms for sense 4 are determine, find out, ascertain - all very appropriate for scientific research. The examples for sense 9 are about interpersonal deception. The scientific context strongly favors sense 4.

Also, in WordNet, sense 4 (find%2:32:00) is the "ascertain" sense, which is exactly what scientists do when they find that something is true through research.

So I'll go with sense 4.

Wait, I need to be absolutely sure. Let me look at the sense key numbering again.
find%2:32:00:: - this is sense 4 in the candidate list.
find%2:31:09:: - this is sense 9.

In WordNet, the lexicographer file for 32 is "verb.cognition" (specifically, think, calculate, reason, estimate). The file for 31 is also verb.cognition (know, believe). The distinction between 31 and 32 is that 32 is more about cognitive actions leading to conclusions (determine, calculate), while 31 is about cognitive states (believe, think). So sense 4 (file 32) is about the cognitive act of establishing something, while sense 9 (file 31) is about the cognitive act of discovering a fact. Both are cognitive.

But sense 4 explicitly mentions "investigation, experiment, survey, or study" in its definition. That makes it the perfect match for a scientist studying chromosomes.

I will choose sense 4.

Actually, one last check: could it be sense 8 (find%2:36:00)? File 36 - what is that? If 36 is verb.creation, that would be odd. But I think 36 might be "verb.cognition" as well, or perhaps "verb.communication"? No, looking at standard WordNet lexicographer file numbers:
- 31: verb.cognition
- 32: verb.cognition
- 33: verb.competition
- 34: verb.consumption
- 35: verb.contact
- 36: verb.communication
- 37: verb.creation
- 38: verb.emotion
- 39: verb.perception
- 40: verb.contact

Wait, that doesn't seem right because 40 is listed as verb.contact in my memory but the candidate has find%2:40 which seems to be physical finding. Let me not get bogged down in file numbers.

The definition for sense 8 is "make a discovery, make a new finding". This is a creative act. Dr. Knudson's finding was indeed a new finding. But the context emphasizes the process: he was working on a theory, looking at chromosomes, and established this inheritance pattern. It's the result of investigation.

I think sense 4 is still better because the definition explicitly mentions "investigation" and "study".

Final decision: sense 4.

Wait, I want to look at the exact JSON format requested: {"sense_index": 4}

The user said "Return only a JSON object exactly like {"sense_index": 3}." and "Do not answer with a WordNet sense key."

So I should return {"sense_index": 4}.

But let me reconsider if it could be sense 9 one more time. The example "She found that he had lied to her" is propositional. Our sentence is propositional. In WordNet, sense 9 (find%2:31:09) is often the default for "find that". But sense 4 also can take "that" clauses.

Actually, looking at the definition of sense 9: "make a discovery". The example: "She found that he had lied to her; The story is false, so far as I can discover". This seems to be about learning something, often through indirect evidence or being told.

In contrast, sense 4: "establish after a calculation, investigation, experiment, survey, or study". This is active research.

Dr. Knudson was actively researching. He didn't just happen to learn this; he established it through his work with microscopes and chromosomes. So sense 4 is definitely better.

Yes, I'm confident. Sense 4.

3. sense_key=child%1:18:06:: | definition=an immature childish person | synonyms=baby | examples=he remained a child in practical matters as long as he lived; stop being a baby!
- This is about immaturity/childishness, not applicable here.

4. sense_key=child%1:18:07:: | definition=a member of a clan or tribe | examples=the children of Israel
- This is metaphorical/tribal, not applicable here.

Now between sense 1 and sense 2:
The context mentions "infant" earlier, and talks about "children with the eye cancer" inheriting damaged genes from parents. The key here is the parent-child relationship. The text says "inherited... from a parent" and "from a parent who had had the disease." This strongly emphasizes the filial relationship - these are offspring of parents.

However, the text also mentions "infant" and this is about eye cancer which typically affects young children (retinoblastoma). But the critical aspect in this specific sentence is the inheritance from parents - the parent-child genetic relationship.

Let me look more carefully. The sentence is: "Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease."

The word "children" here refers to offspring/human offspring. The examples for sense 2 include "they had three children" and "send their kids to college" - emphasizing the parent-offspring relationship. The examples for sense 1 include "she writes books for children" and "they're just kids" - emphasizing young people in general.

In this context, the children are specifically being discussed as offspring of parents (inheriting from a parent). This strongly points to sense 2. The fact that they have eye cancer (which affects the young) might suggest sense 1, but the inheritance context makes the parent-offspring relationship primary.

Wait, let me reconsider. Retinoblastoma is a cancer of the eye that primarily affects young children, usually under 5. The text mentions "infant" earlier. But the specific sentence is about inheritance from parents.

Actually, looking at WordNet sense distinctions:
- child%1:18:00:: = young person (emphasis on being young)
- child%1:18:01:: = human offspring of any age (emphasis on being offspring)

In the context: "some children with the eye cancer had inherited... from a parent"
The inheritance aspect strongly signals the "offspring" sense. Also, the earlier mention of "infant" suggests these are indeed young, but the disambiguation should focus on the immediate context.

However, I should check if there's any reason to prefer sense 1. If the text were emphasizing their youth, sense 1 might be better. But here, the key relationship is parent-to-child inheritance. The word "children" is used to mean "offspring" in a genetic/medical context.

Actually, looking at the examples again:
Sense 1: "she writes books for children" - children as young people
Sense 2: "they had three children" - children as offspring

The phrase "children with the eye cancer" could go either way, but "had inherited... from a parent" strongly pushes toward sense 2 (offspring). The parenthetical "(son or daughter) of any age" fits because even though they happen to be young (since it's retinoblastoma), the sense is about the filial relationship.

I think sense 2 is the best fit.

Wait, I need to be careful. Let me think about whether WordNet distinguishes these in practice. In many WSD datasets, "children" in medical contexts referring to pediatric patients often gets sense 1 (young person). But when the context explicitly mentions parents and inheritance, sense 2 (offspring) is often correct.

Let me look at the exact wording again: "Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease."

The parallel structure: parent who had had the disease → children who inherited...
This establishes the parent-offspring relationship as the key semantic element.

Also, earlier: "an infant inherited... from one parent" - infant is a young child, but the emphasis is on inheritance from parents.

I think sense 2 is correct.

But let me double-check. Could sense 1 be better because these are specifically young people (since eye cancer in this context is retinoblastoma, a childhood cancer)? The gloss for sense 1 is "a young person of either sex." The gloss for sense 2 is "a human offspring (son or daughter) of any age."

The phrase "children with the eye cancer" in a medical study could be referring to pediatric patients. However, the immediate context about inheritance from parents is very strong.

Actually, looking at typical WordNet sense distributions, sense 1 is the most common for general "children." Sense 2 is used when emphasizing the family relationship. Given "from a parent," this is clearly emphasizing family relationship.

I'll go with sense 2.

Wait, I need to make sure about the indexing. The user says "Choose the single best indexed sense" and "Return only a JSON object exactly like {"sense_index": 3}."

The candidates are numbered 1, 2, 3, 4. So I should return {"sense_index": 2}.

Let me reconsider one more time. Is there any chance it's sense 1?
- "children" as young people: would fit with "infant" mentioned earlier
- But the inheritance context is very strong for sense 2

In WordNet, sense 1 (child%1:18:00) is the "young person" sense, often used for "children" as a group of young people. Sense 2 (child%1:18:01) is the "offspring" sense.

Consider: "they had three children" (sense 2) vs "she writes books for children" (sense 1).
In our text: "some children... had inherited... from a parent" - this is much closer to "they had three children" (offspring) than to "books for children" (young people). The children are being discussed specifically in relation to their parents.

Yes, sense 2 is correct.

Actually, I want to check one more thing. The text says "an infant inherited... from one parent" and then later "some children with the eye cancer had inherited... from a parent." The shift from "infant" to "children" - both refer to the young, but "children" in the second case is again in the context of inheritance.

Also, if they meant just young people in general, they might have said "some patients" or "some young people." But "children" paired with "parent" strongly suggests offspring.

Final decision: sense_index 2.

The user wants me to perform Word Sense Disambiguation (WSD) on the word "eye" in the given context.

 Let me analyze the context:
 - The text is about eye cancer (specifically retinoblastoma, though not explicitly named)
 - It mentions "children with the eye cancer"
 - It discusses inheritance of damaged genes/chromosomes related to this cancer
 - The cancer affects the eye organ

 Now let's look at the candidate senses:

 1. sense_key=eye%1:08:00:: | definition=the organ of sight | synonyms=oculus, optic
    - This refers to the physical organ of vision.
    - In the context "eye cancer", this would mean cancer of the eye organ.

 2. sense_key=eye%1:09:00:: | definition=good discernment (either visually or as if visually) | examples=she has an eye for fresh talent; he has an artist's eye
    - This is a metaphorical sense about judgment or discernment.
    - Doesn't fit "eye cancer".

 3. sense_key=eye%1:09:01:: | definition=attention to what is seen | examples=he tried to catch her eye
    - This is about attention or gaze.
    - Doesn't fit "eye cancer".

 4. sense_key=eye%1:15:00:: | definition=an area that is approximately central within some larger region | synonyms=center, centre, middle, heart | examples=it is in the center of town; they ran forward into the heart of the struggle
    - This is about a central location (like the eye of a storm).
    - Doesn't fit "eye cancer".

 5. sense_key=eye%1:06:00:: | definition=a small hole or loop (as in a needle) | examples=the thread wouldn't go through the eye
    - This is about a physical hole (like in a needle).
    - Doesn't fit "eye cancer".

 The context clearly refers to "eye cancer" - cancer affecting the organ of sight. The text discusses:
 - "in the eye cancer"
 - "children with the eye cancer"
 - Looking at chromosomes under a microscope related to this cancer

 This is clearly referring to the anatomical organ, not a metaphorical sense.

 Therefore, the correct sense is sense 1: "the organ of sight".

 The user wants the output as: {"sense_index": 1}

 Wait, let me double-check the sense indices. The user lists:
 1. sense_key=eye%1:08:00:: ...
 2. sense_key=eye%1:09:00:: ...
 3. sense_key=eye%1:09:01:: ...
 4. sense_key=eye%1:15:00:: ...
 5. sense_key=eye%1:06:00:: ...

 So sense 1 is indeed the organ of sight.

 The context is clearly about retinoblastoma or similar eye cancer affecting the physical organ.

 Answer should be: {"sense_index": 1}

 Now let's look at the candidate senses:

 1. sense_key=inherit%2:40:00:: | definition=obtain from someone after their death | examples=I inherited a castle from my French grandparents

    - This is about genetic inheritance from parents. The example mentions inheriting eyesight from a mother, which is biological/genetic.

 The context clearly involves:
 - An infant inheriting from parents
 - Damaged copies of genes
 - Chromosome 13
 - Eye cancer (genetic disease)

 Analysis:
 - Sense 1 refers to physical harm, injury, or spoiling of objects or things. This fits the context of a chromosome being physically altered (missing a bit, harmed).
 - Sense 2 refers to reputation being harmed (disrepute, discredited). This is metaphorical/social damage, not physical damage to a biological structure.

 The context clearly describes physical damage to a chromosome (genetic material) - "a bit of chromosome 13 was missing." This is literal physical harm to the chromosome structure.

 Therefore, Sense 1 is the correct choice.

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

 Context analysis:
 The text is about genetics and cancer. Specifically, it discusses:
 - "an infant inherited a damaged copy of a gene from one parent and a normal copy from the other"
 - "inherited a damaged copy of chromosome No. 13"

 Here, "copy" refers to one of the two instances of a gene or chromosome that a person inherits (one from each parent). In genetics, we talk about having two "copies" of a gene - one maternal and one paternal.

 Looking at the candidate senses:

 1. sense_key=copy%1:10:00:: - "a reproduction of a written record" - This is about documents/transcripts. Not relevant here.

 2. sense_key=copy%1:06:00:: - "a thing made to be similar or identical to another thing" - Examples include "she made a copy of the designer dress" and "the clone was a copy of its ancestor". This seems close - a chromosome or gene copy is similar/identical to the original from the parent.

 3. sense_key=copy%1:10:01:: - "matter to be printed; exclusive of graphical materials" - This is about text/copywriting. Not relevant.

 4. sense_key=copy%1:10:02:: - "material suitable for a journalistic account" - Also about journalism/writing. Not relevant.

 Sense 2 seems to be the best fit. In genetics, when we say someone inherits a "copy" of a gene or chromosome, we mean they receive one instance/version of it from a parent, which is similar/identical to the parent's version. The word is being used to mean one of two similar items (the two alleles or homologous chromosomes).

 The definition "a thing made to be similar or identical to another thing" fits because the inherited chromosome/gene is similar/identical to the parent's chromosome/gene.

 While in biology we might think of this as "allele" or specific biological terminology, in the general language of the text, "copy" is being used in the sense of "duplicate" or "version" - one of a pair of similar things.

 Sense 2 is the only one that makes sense for physical objects (chromosomes/genes as things), while the others are clearly about written/textual material.

 Therefore, the answer should be sense_index 2.

 - It mentions "an infant inherited a damaged copy of a gene from one parent"
 - It mentions "inherited a damaged copy of chromosome No. 13 from a parent who had had the disease"
 - The context involves human genetics, inheritance from father or mother
 - The parent is described as "who had had the disease" - referring to a human who had eye cancer

 Now look at the candidate senses:
 1. sense_key=parent%1:18:00:: | definition=a father or mother; one who begets or one who gives birth to or nurtures and raises a child; a relative who plays the role of guardian
    - This is the human sense - father or mother
    - 1:18 refers to noun.person (people)

 2. sense_key=parent%1:03:00:: | definition=an organism (plant or animal) from which younger ones are obtained
    - This is the biological/organism sense
    - 1:03 refers to noun.animal or noun.plant? Actually 1:03 usually refers to noun.animal or noun.plant in WordNet, but let me check... actually looking at the format, %1:03:00 suggests noun.animal (03 is animal, 18 is person)

 The context clearly refers to a human parent (father or mother) who had the disease (eye cancer) and passed on a damaged chromosome to their child. This is clearly the human sense, not the general biological organism sense.

 Therefore, sense 1 is the correct choice.

 Wait, let me double-check the sense keys to make sure I understand the indexing correctly.
 - sense_key=parent%1:18:00:: is listed first, so it's index 1

The user wants me to perform Word Sense Disambiguation for the word "actually" in the given context.

Let me analyze the context:
"Under a microscope he could <t>actually</t> see that a bit of chromosome 13 was missing."

The sentence is saying that under a microscope, he could see (in actual fact/really) that a bit of chromosome 13 was missing. It's emphasizing that the observation was real and concrete, not theoretical.

Let me look at the candidate senses:

1. sense_key=actually%4:02:01:: | definition=in actual fact | synonyms=really | examples=to be nominally but not actually independent; no one actually saw the shark
   - This sense means "really" or "in fact". The example "no one actually saw the shark" fits with the idea of real vs. theoretical observation.
   - In our context: "he could actually see" = "he could really see" / "he could in fact see" (as opposed to just inferring or theorizing).

2. sense_key=actually%4:02:00:: | definition=used to imply that one would expect the fact to be the opposite of that stated; surprisingly | synonyms=in reality | examples=you may actually be doing the right thing by walking out; she actually spoke Latin
   - This sense conveys surprise or counter-expectation. The context doesn't suggest surprise or something unexpected. It's just stating a fact about what could be observed.

3. sense_key=actually%4:02:03:: | definition=at the present moment | examples=the transmission screen shows the picture that is actually on the air
   - This is about "currently" or "at the present moment". The context is about a past scientific observation, not about present moment.

4. sense_key=actually%4:02:02:: | definition=as a sentence modifier to add slight emphasis | examples=actually, we all help clear up after a meal; actually, I haven't seen the film
   - This is when "actually" modifies the whole sentence, often at the beginning or as a discourse marker. Here "actually" is modifying the verb "see" within the clause, not serving as a sentence-level discourse marker. Also, it's not at the beginning of the sentence.

So sense 1 seems best: "in actual fact" / "really". The contrast is between theoretical inference and actual visual observation. Before, there was "no way to prove" the theory, but under a microscope he could "actually" (really/in fact) see the missing bit.

Wait, let me double-check the WordNet sense numbering. The user lists:
1. sense_key=actually%4:02:01::
2. sense_key=actually%4:02:00::
3. sense_key=actually%4:02:03::
4. sense_key=actually%4:02:02::

The user asks to return {"sense_index": 3} format, where the index refers to the numbered list provided (1, 2, 3, 4), not the WordNet offset.

So the answer should be {"sense_index": 1}.

Let me verify:
- "he could actually see" - this is using "actually" to mean "really" or "in actual fact", distinguishing between theoretical knowledge and direct observation.
- The example for sense 1: "no one actually saw the shark" - this is exactly parallel: "actually saw" = "really saw".
- Sense 2 would be more like "surprisingly, he could see" which doesn't fit.
- Sense 3 would be "he could currently see" which doesn't fit.
- Sense 4 would require it to be more of a discourse marker, but here it's integrated into the VP.

Yes, sense_index: 1.

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

 First, let me analyze the context:
 - The text is about Dr. Knudson studying eye cancer and chromosomes.
 - Key sentence: "Under a microscope he could actually <t>see</t> that a bit of chromosome 13 was missing."
 - He's looking at chromosomes under a microscope.
 - He is physically observing something with his eyes - specifically seeing that part of chromosome 13 was missing.

 Now let's look at the candidate senses:

 1. sense_key=see%2:39:00:: | definition=perceive by sight or have the power to perceive by sight | examples=You have to be a good observer to see all the details; Can you see the bird in that tree?
 - This is about perceiving by sight. The context mentions "Under a microscope" and seeing missing genetic material. This seems physical/visual observation.

 2. sense_key=see%2:31:01:: | definition=perceive (an idea or situation) mentally | synonyms=understand, realize, realise | examples=Now I see!; I just can't see your point
 - This is mental understanding, not physical seeing. Doesn't fit.

 3. sense_key=see%2:39:02:: | definition=perceive or be contemporaneous with | synonyms=witness, find | examples=We found Republicans winning the offices; You'll see a lot of cheating in this school
 - This is more about witnessing events over time. Not quite right for looking through a microscope.

 4. sense_key=see%2:36:00:: | definition=imagine; conceive of; see in one's mind | synonyms=visualize, visualise, envision | examples=I can't see him on horseback!
 - This is imagination, not actual visual perception.

 5. sense_key=see%2:31:00:: | definition=deem to be | synonyms=consider, reckon, view, regard | examples=She views this quite differently from me
 - This is about opinion/judgment, not visual perception.

 6. sense_key=see%2:31:02:: | definition=get to know or become aware of, usually accidentally | synonyms=learn, hear | examples=I learned that she has two grown-up children
 - This is about learning information, not visual observation.

 7. sense_key=see%2:39:03:: | definition=see or watch | synonyms=watch, view, catch, take in | examples=view a show on television
 - This is viewing/entertainment watching.

 8. sense_key=see%2:38:00:: | definition=come together | synonyms=meet, run into
 - Social meeting.

 9. sense_key=see%2:32:00:: | definition=find out, learn, or determine with certainty | synonyms=determine, check
 - This is about verifying/investigating, though with a focus on results of inquiry.

 10. sense_key=see%2:31:03:: | definition=be careful or certain to do something
 - Making sure.

 11-16, 18, 21-24: Various other meanings (professional visits, dating, escorting, etc.) that clearly don't fit.

 17. sense_key=see%2:39:05:: | definition=see and understand, have a good eye | examples=The artist must first learn to see
 - This is about aesthetic perception or deep observation, but still physical.

 19. sense_key=see%2:39:11:: | definition=observe as if with an eye | examples=The camera saw the burglary and recorded it
 - Metaphorical seeing (camera).

 20. sense_key=see%2:39:13:: | definition=observe, check out, and look over carefully or inspect | synonyms=examine | examples=The customs agent examined the baggage; I must see your passport before you can enter the country
 - This is careful inspection/examination.

 Now, which sense best fits "Under a microscope he could actually see that a bit of chromosome 13 was missing"?

 It's between:
 1. perceive by sight (basic visual perception)
 20. observe, check out, and look over carefully or inspect (examine)

 The context mentions:
 - "under a microscope"
 - "actually see"
 - "a bit of chromosome 13 was missing"

 This is careful scientific observation. However, sense 1 is "perceive by sight or have the power to perceive by sight" which is the basic visual perception sense.

 Let me check the WordNet distinctions more carefully.

 Sense 1 (see%2:39:00::) is the most basic visual perception sense.
 Sense 20 (see%2:39:13::) is specifically about inspecting/examining carefully.

 The phrase "Under a microscope suggests careful examination, but the specific verb "see" here is being used to mean visually perceive the absence of something.

 Let me look at the examples for sense 20: "The customs agent examined the baggage; I must see your passport before you can enter the country"

 This implies "see" as in "inspect" or "check".

 In the context: "Under a microscope he could actually see that a bit of chromosome 13 was missing."

 This is visual detection/observation. He's looking through a microscope and visually detecting that genetic material is missing.

 However, looking at the previous sentence: "under a microscope they could see the 23 pairs of chromosomes"

 And then: "Under a microscope he could actually see that a bit of chromosome 13 was missing."

 This is basic visual perception - using a microscope to visually detect something.

 But wait, is there a sense specifically about detecting/perceiving?

 Actually, looking at sense 1 vs sense 20:

 Sense 1: perceive by sight or have the power to perceive by sight | examples=You have to be a good observer to see all the details; Can you see the bird in that tree?

 Sense 20: observe, check out, and look over carefully or inspect | synonyms=examine | examples=The customs agent examined the baggage; I must see your passport before you can enter the country

 The context suggests that "see" here is about visual perception through a microscope. The key is that he is observing a physical reality (missing bit of chromosome) using his eyes (assisted by microscope).

 However, "actually see" suggests that this is about direct visual perception - actually perceiving with the eyes rather than inferring.

 Given the context of looking through a microscope to view chromosomes, and the parallel construction with "under a microscope they could see the 23 pairs of chromosomes", this seems to be sense 1: basic visual perception.

 But let me reconsider sense 20. Is "see" here being used to mean "examine"? The direct object is "that a bit of chromosome 13 was missing" - a clause, not a physical object being inspected like a passport.

 Actually, looking at the syntax: "see that..." - this often introduces a mental perception or realization sense. But here it's "see that a bit of chromosome 13 was missing" where "that" introduces what was visually observed.

 Let me check sense 6: see%2:31:02:: = get to know or become aware of...
 Example: "I see that you have been promoted" - this is intellectual realization, often from visual cues but not necessarily.

 But the context explicitly says "Under a microscope" and "actually", which emphasizes the physical, visual nature.

 Sense 1 seems most appropriate: perceive by sight.

 However, let me look at sense 3: perceive or be contemporaneous with | witness | examples: "You'll see a lot of cheating in this school"
 This is about witnessing events.

 Sense 7: see or watch | view | examples: "view a show on television"
 This is entertainment viewing.

 Given that the subject is a scientist looking through a microscope at biological samples, and it's about detecting the absence of genetic material, and the contrast is with "no way to prove" (theoretical) vs "actually see" (observational), and the earlier mention of "visible" damage and "see the 23 pairs", this is clearly sense 1: the basic visual perception sense.

 The mention of "see" in the previous clause: "they could see the 23 pairs of chromosomes" - this is clearly visual perception (sense 1).
 Then: "Under a microscope he could actually see that a bit of chromosome 13 was missing" - this maintains the same sense.

 Actually, looking carefully at the numbering in the candidate list:
 1. sense_key=see%2:39:00::
 2. sense_key=see%2:31:01::
 ...

 So index 1 is see%2:39:00:: which is the basic visual perception sense.

 Index 20 is see%2:39:13:: which is inspect/examine.

 But given the context confirms physical observation ("Under a microscope", "actually see", "missing piece"), and the earlier parallel "could see the 23 pairs", sense 1 is the best fit.

 Wait, I should double-check if there's any other sense that might fit better.

 Sense 17: "see and understand, have a good eye" - The artist must first learn to see.
 This is about deep perception/understanding visually. Not quite right - the scientist isn't learning to see artistically.

 Sense 19: "observe as if with an eye" - The camera saw...
 This is metaphorical.

 So it's between 1 and 20.

 The key difference: sense 20 has synonym "examine" and examples involving checking documents/baggage - implying a closer look for validation purposes. Sense 1 is just "perceive by sight" - the basic ability to see.

 In the sentence: "he could actually see that a bit of chromosome 13 was missing" - this is reporting what was visually perceived. The focus is on the visual detection of the absence.

 Given the parallel with "see the 23 pairs" (definitely sense 1) and "visible damage" (relating to sight), sense 1 is most consistent.

 Therefore, the answer should be {"sense_index": 1}.

 But let me reconsider if "see that..." constructions might favor a different sense.

 "I see that..." often triggers sense 6 (learn/become aware) or sense 2 (understand mentally).

 But here: "Under a microscope he could actually see that..." - the microscope makes it clear this is physical vision. The "that" clause reports what was visually observed (the missing bit).

 So yes, sense 1.

 One final check: is there any chance this is sense 20 (inspect)?
 "I must see your passport" - could "Under a microscope he could actually see..." be similar to inspection?
 He is inspecting the chromosomes...

 However, WordNet sense 20 (= inspect) is typically used with direct objects like "see the passport", "see the baggage". With a "that" clause indicating what was observed, it's more likely the basic perception sense (1).

 Also, the example for sense 1 includes: "You have to be a good observer to see all the details" - this matches the scientific observation context.

 Final decision: sense_index 1.

The user wants me to perform Word Sense Disambiguation for the word "bit" in the given context.

Context analysis:
- The text is about genetics, chromosomes, and cancer.
- Specifically: "Under a microscope he could actually see that a bit of chromosome 13 was missing."
- This refers to a physical piece/portion of a chromosome that is missing.
- It's talking about a physical fragment or piece of something (chromosome).

Candidate senses analysis:
1. bit%1:23:01:: - a small piece or quantity of something | synonyms=spot | examples=a spot of tea; a bit of paper
   - This is a general "small piece or quantity". Could fit.
2. bit%1:17:00:: - a small fragment of something broken off from the whole | synonyms=chip, flake, fleck, scrap | examples=a bit of rock caught him in the eye
   - This implies something broken off. A chromosome missing a piece - the piece is broken off or missing from the whole. This seems very physical and concrete.
3. bit%1:28:00:: - time. Not relevant.
4. bit%1:11:00:: - an instance of some kind. Not relevant.
5. bit%1:06:01:: - horse bit. Not relevant.
6. bit%1:23:00:: - binary digit. Not relevant.
7. bit%1:13:00:: - food. Not relevant.
8. bit%1:10:01:: - a small fragment | synonyms=snatch | examples=overheard snatches of their conversation
   - This is for conversation/abstract fragments (snatches of conversation).
9. bit%1:10:00:: - theatrical performance. Not relevant.
10. bit%1:06:02:: - key part. Not relevant.
11. bit%1:06:00:: - drill bit. Not relevant.

So it's between sense 1 and sense 2 (and maybe 8, but 8 seems for speech/text).

Sense 1: bit%1:23:01:: - a small piece or quantity of something. This is a very general sense. Examples: "a spot of tea; a bit of paper". This is often used with uncountable nouns or general "some amount".

Sense 2: bit%1:17:00:: - a small fragment of something broken off from the whole. Synonyms: chip, flake, fleck, scrap. Example: "a bit of rock caught him in the eye". This implies a physical piece that has broken off from a larger whole.

In the context: "a bit of chromosome 13 was missing". A chromosome is a physical structure. A piece of it is missing. This piece is a fragment of the whole chromosome. The synonyms "chip, flake, fleck, scrap" and the definition "a small fragment of something broken off from the whole" strongly suggest this is the correct sense. The chromosome is a physical object, and a piece has broken off/been lost from it.

Sense 1 could also work ("a small piece or quantity"), but sense 2 is more specific to physical fragments broken off from a whole object. Given the biological context of a chromosome being a physical structure under a microscope, and a piece being missing (implying it was part of the whole and is now gone/broken off), sense 2 seems better.

Wait, the sense keys given are:
- bit%1:23:01:: -> if 23 is noun.state, that doesn't fit "a small piece or quantity".
- bit%1:17:00:: -> if 17 is noun.plant, that doesn't fit "fragment".

Hmm, maybe the lexfile numbering is different in different versions, or I'm misremembering. Let me not rely on the lexfile numbers and instead rely on the definitions and examples provided.

Sense 1: "a small piece or quantity of something" | spot | a spot of tea; a bit of paper
Sense 2: "a small fragment of something broken off from the whole" | chip, flake, fleck, scrap | a bit of rock caught him in the eye

The context: "a bit of chromosome 13 was missing". Chromosome 13 is a physical structure. A piece of it is missing. This is literally a fragment broken off (or deleted) from the whole chromosome.

Sense 2's example "a bit of rock caught him in the eye" is very analogous - a physical fragment of a larger object.

Sense 1's examples "a spot of tea; a bit of paper" - "a bit of paper" could be similar, but "paper" here might be uncountable (some paper) or a piece of paper. But sense 2 specifically emphasizes "broken off from the whole" which is exactly what happens when a piece of a chromosome is missing (deleted).

Also, in biological/genetic contexts, when describing chromosomal deletions, "a bit of chromosome was missing" uses "bit" to mean a physical fragment.

Sense 8: "a small fragment" | snatch | overheard snatches of their conversation. This is specifically for auditory/verbal fragments.

Therefore, sense 2 (bit%1:17:00::) is the best choice.

Wait, I need to make sure about the indexing. The user lists them 1-11. I need to return the index number from the list.

Candidate 1: sense_key=bit%1:23:01::
Candidate 2: sense_key=bit%1:17:00::
Candidate 3: sense_key=bit%1:28:00::
Candidate 4: sense_key=bit%1:11:00::
Candidate 5: sense_key=bit%1:06:01::
Candidate 6: sense_key=bit%1:23:00::
Candidate 7: sense_key=bit%1:13:00::
Candidate 8: sense_key=bit%1:10:01::
Candidate 9: sense_key=bit%1:10:00::
Candidate 10: sense_key=bit%1:06:02::
Candidate 11: sense_key=bit%1:06:00::

So sense 2 is index 2.

Let me reconsider if sense 1 could be better. "a small piece or quantity of something". Chromosome material could be considered a quantity? But "bit of chromosome 13" refers to a physical segment. The phrase "was missing" and "missing piece" strongly suggests a fragment broken off. Also, the synonym "scrap" and "chip" are very physical.

In WordNet, sense 2 (bit%1:17:00::) is likely the "chip, flake, fleck, scrap" sense under noun.object or similar. Sense 1 (bit%1:23:01::) might be under noun.quantity or noun.substance.

Actually, looking at the sense keys again:
- bit%1:23:01:: - if this is noun.quantity, "a small piece or quantity" fits quantity.
- bit%1:17:00:: - if 17 is noun.plant... no. Wait, maybe the numbers are:
  - 17 = noun.object? In some numbering? Let me check PWN lexfile numbers again carefully.

Actually, I found a reference:
noun.Tops: 00
noun.act: 01
noun.animal: 02
noun.artifact: 03
noun.attribute: 04
noun.body: 05
noun.cognition: 06
noun.communication: 07
noun.event: 08
noun.feeling: 09
noun.food: 10
noun.group: 11
noun.location: 12
noun.motive: 13
noun.object: 14
noun.person: 15
noun.phenomenon: 16
noun.plant: 17
noun.possession: 18
noun.process: 19
noun.quantity: 20
noun.relation: 21
noun.shape: 22
noun.state: 23
noun.substance: 24
noun.time: 25
noun.weather: 26? (maybe not used)

If 17 is noun.plant, then bit%1:17:00:: being "a small fragment of something broken off from the whole" doesn't fit noun.plant. Unless 17 is something else.

Wait, maybe the lexfile numbers in the sense key are different. Let me check WordNet 3.1 or 3.0 documentation.

Actually, in WordNet, the lexicographer file numbers might be:
00  adj.all
01  adj.pert
02  adv.all
03  noun.Tops
04  noun.act
05  noun.animal
06  noun.artifact
07  noun.attribute
08  noun.body
09  noun.cognition
10  noun.communication
11  noun.event
12  noun.feeling
13  noun.food
14  noun.group
15  noun.location
16  noun.motive
17  noun.object
18  noun.person
19  noun.phenomenon
20  noun.plant
21  noun.possession
22  noun.process
23  noun.quantity
24  noun.relation
25  noun.shape
26  noun.state
27  noun.substance
28  noun.time
29  noun.weather
30  verb.body
31  verb.change
32  verb.cognition
33  verb.communication
34  verb.competition
35  verb.consumption
36  verb.contact
37  verb.creation
38  verb.emotion
39  verb.motion
40  verb.perception
41  verb.possession
42  verb.social
43  verb.stative
44  verb.weather
45  adj.ppl

Ah! This is the correct mapping! I was off by a lot.
So:
- 03: noun.Tops
- 04: noun.act
- 05: noun.animal
- 06: noun.artifact
- 07: noun.attribute
- 08: noun.body
- 09: noun.cognition
- 10: noun.communication
- 11: noun.event
- 12: noun.feeling
- 13: noun.food
- 14: noun.group
- 15: noun.location
- 16: noun.motive
- 17: noun.object
- 18: noun.person
- 19: noun.phenomenon
- 20: noun.plant
- 21: noun.possession
- 22: noun.process
- 23: noun.quantity
- 24: noun.relation
- 25: noun.shape
- 26: noun.state
- 27: noun.substance
- 28: noun.time
- 29: noun.weather

This makes much more sense!
- bit%1:23:01:: -> noun.quantity: "a small piece or quantity of something"
- bit%1:17:00:: -> noun.object: "a small fragment of something broken off from the whole"
- bit%1:28:00:: -> noun.time: "an indefinitely short time"
- bit%1:11:00:: -> noun.event: "an instance of some kind"
- bit%1:06:01:: -> noun.artifact: "piece of metal held in horse's mouth"
- bit%1:23:00:: -> noun.quantity: "a unit of measurement of information" (binary digit)
- bit%1:13:00:: -> noun.food: "a small amount of solid food"
- bit%1:10:01:: -> noun.communication: "a small fragment" (snatches of conversation)
- bit%1:10:00:: -> noun.communication: "a short theatrical performance"
- bit%1:06:02:: -> noun.artifact: "the part of a key"
- bit%1:06:00:: -> noun.artifact: "the cutting part of a drill"

Yes! This is correct. So:
- Sense 2 (bit%1:17:00::) is noun.object: a small fragment of something broken off from the whole.
- Sense 1 (bit%1:23:01::) is noun.quantity: a small piece or quantity.

Given that a chromosome is a physical object (noun.object), and we're talking about a fragment broken off from it (missing piece), sense 2 is definitely the best fit. The definition explicitly mentions "broken off from the whole" which matches the idea of a chromosomal deletion where a piece is missing.

Sense 1 is more about quantity or indefinite amount (a bit of tea, a bit of paper). While "a bit of paper" could be physical, it's categorized under quantity. Sense 2 is the physical object sense.

Therefore, the answer is index 2.

I need to return only a JSON object: {"sense_index": 2}
