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

Context analysis:
- The text describes an earthquake scenario in San Francisco (Marina district)
- It mentions liquefaction of fill areas
- A woman in a three-story apartment was able to walk out the window of the third floor onto "street" level after the quake
- The house settled down into the ground

The key phrase is: "walk out the window of the third floor onto street level"

This suggests that due to the earthquake and liquefaction, the building sank or the ground level changed such that the third floor became level with the street.

Now let's look at the candidate senses:

1. street%1:06:00:: - a thoroughfare (usually including sidewalks) that is lined with buildings
   - Examples: "they walked the streets of the small town; he lives on Nassau Street"
   - This refers to the street as a thoroughfare/roadway in general

2. street%1:06:01:: - the part of a thoroughfare between the sidewalks; the part of the thoroughfare on which vehicles travel
   - Examples: "be careful crossing the street"
   - This refers specifically to the roadway/paved part where vehicles drive

3. street%1:26:00:: - the streets of a city viewed as a depressed environment...
   - This is a metaphorical/social sense about urban poverty/crime

4. street%1:26:01:: - a situation offering opportunities
   - Metaphorical: "worked both sides of the street"

5. street%1:14:00:: - people living or working on the same street
   - Collective noun for people

In the context "onto street level", the word "street" is being used to indicate the level/elevation of the street surface - i.e., the ground level where the street is located. This is closest to sense 1 or 2, but actually, looking carefully:

"Street level" typically refers to the level of the street surface - the ground level. In the context of buildings, "street level" means the level at which the street is, i.e., the ground floor level.

However, looking at the specific senses:
- Sense 1: the thoroughfare including sidewalks (the whole street as a public way)
- Sense 2: specifically the roadway between sidewalks (where vehicles travel)

In the phrase "street level", we're referring to the elevation/height of the street surface. This is most aligned with sense 1, which is the general thoroughfare concept. But actually, looking at the examples:

Sense 1 examples: "they walked the streets", "he lives on Nassau Street" - this treats street as a location/place
Sense 2 examples: "be careful crossing the street" - this treats street as the surface to be crossed

But "street level" refers to the height/elevation of the street surface. In WordNet, sense 1 (street%1:06:00::) is the general sense of a thoroughfare lined with buildings. Sense 2 is more specific to the vehicular travel portion.

Actually, looking at the context again: "walk out the window of the third floor onto street level" - this means the third floor became level with the street (the ground/surface level).

Between sense 1 and sense 2:
- Sense 1 is the broader sense of the thoroughfare/street as a whole
- Sense 2 is the specific paved part for vehicles

"Street level" typically corresponds to the level of the thoroughfare (sense 1), not specifically the vehicular portion (sense 2). However, in many contexts, they overlap.

But wait, looking at the specific wording in the context: "onto street level" - this is referring to the elevation of the street surface.

Actually, looking at WordNet's hierarchy:
- Sense 1: street as a thoroughfare (including sidewalks) - this is the road as a whole entity
- Sense 2: the specific part between sidewalks where vehicles travel

In "street level", we mean the level of the ground where the street is. This aligns with sense 1, the general thoroughfare.

However, I should reconsider. The phrase "street level" is an idiom meaning ground floor level, the level of the street surface.

Looking at the examples for sense 1: "they walked the streets of the small town" - this refers to the streets as pathways.
Sense 2: "be careful crossing the street" - refers to crossing the road surface.

In the context of an earthquake where a building sinks, "street level" refers to the normal ground level where the street is located. This is the thoroughfare level.

Between sense 1 and 2, sense 1 is the more general and appropriate sense for "street level" because it refers to the street as a reference point for elevation/height.

Sense 3, 4, and 5 are clearly wrong:
- 3 is about urban decay (metaphorical)
- 4 is about opportunities (metaphorical)
- 5 is about people (collective)

So it's between 1 and 2.

Sense 1: "a thoroughfare (usually including sidewalks) that is lined with buildings"
Sense 2: "the part of a thoroughfare between the sidewalks; the part of the thoroughfare on which vehicles travel"

"Street level" refers to the elevation of the street surface. While sense 2 describes the surface vehicles travel on, sense 1 describes the thoroughfare generally. However, "street level" is a common phrase referring to the level of the street (the ground).

Actually, looking at WordNet definitions carefully:
Sense 1 is the street as a whole thoroughfare (the road including sidewalks).
Sense 2 is specifically the roadway (the part for vehicles).

In the context: "walk out... onto street level" - this means the third floor window was now at the same height as the street (ground level).

I think sense 1 is the best fit because "street level" refers to the level of the thoroughfare/street surface generally, not specifically the vehicular portion (though they are at the same elevation).

But actually, looking at the hypernyms might help (though I don't have them here). Typically sense 1 is the main sense.

Given the context of an earthquake causing a building to settle into the ground, and a woman walking from the third floor window onto the street (which is now at the same level due to liquefaction/subsidence), the word "street" refers to the ground level thoroughfare.

I believe sense 1 (street%1:06:00::) is the correct choice.

Wait, let me reconsider if there's any chance it's sense 2. "Street level" could be interpreted as the level of the roadway. But sense 1 is the primary sense for "street" as a location/place.

Actually, looking at the phrase "street level" in dictionaries, it refers to the level of the street relative to a building - i.e., the ground floor level. This corresponds to the street as a thoroughfare (sense 1).

Therefore, the answer should be sense_index: 1.

But let me double-check: could it be sense 2? If the building sank into the ground, the third floor became level with the street (the road). Sense 2 specifically mentions "the part of the thoroughfare between the sidewalks" - the actual road surface.

However, "street level" is a fixed expression referring to the elevation of the street, and in WordNet, this would map to the general sense of street (sense 1) rather than the specific vehicular portion (sense 2).

Also, looking at the examples:
- Sense 1: "they walked the streets", "he lives on Nassau Street"
- Sense 2: "be careful crossing the street"

The context "onto street level" is about the elevation/height corresponding to where the street is. This is closer to sense 1.

I will go with sense 1.

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

 Context analysis:
 - The text is about an earthquake (liquefaction, quake, house settling)
 - Specific sentence: "A woman in a three-story apartment was able to walk out the window of the third floor onto street <t>level</t> after the quake."
 - This refers to walking from the third floor window down to the street level (ground level)
 - The phrase "street level" means the level/height of the street (ground)

 Looking at candidate senses:

 1. level%1:07:00:: - a position on a scale of intensity or amount or quality
    - This is about abstract scales/degrees, not physical height
    - Examples: "moderate grade of intelligence", "high level of care"
    - Not matching the physical ground/street context

 2. level%1:26:01:: - a relative position or degree of value in a graded group
    - This is about hierarchical grades/tiers (like lumber grades)
    - Not matching physical street height

 3. level%1:26:00:: - a specific identifiable position in a continuum or series or especially in a process
    - This is about stages in a process or continuum
    - Examples: "at what stage are the social sciences?"
    - Not the right sense for physical ground level

 4. level%1:07:01:: - height above ground
    - Examples: "the water reached ankle level", "the pictures were at the same level"
    - This seems relevant - "street level" refers to the height of the street (ground level)

 5. level%1:06:00:: - indicator that establishes the horizontal (spirit level)
    - This is a tool (carpenter's level), not the concept of ground height
    - Not matching

 6. level%1:06:03:: - a flat surface at right angles to a plumb line; horizontal surface
    - Examples: "park the car on the level"
    - This could work - "street level" could mean a horizontal surface
    - But the example shows "park the car on the level" meaning flat ground
    - The context is about height/floor: "walk out the window... onto street level" - this suggests going from third floor to ground level (height)

 7. level%1:09:00:: - an abstract place usually conceived as having depth
    - Examples: "communicates on several levels" - metaphorical
    - Not matching physical street

 8. level%1:06:01:: - a structure consisting of a room or set of rooms at a single position along a vertical scale
    - Synonyms: floor, storey, story
    - Examples: "what level is the office on?"
    - This refers to floors of a building (storey/story)
    - But "street level" is not typically called a "floor" or "storey" - it's the ground level, not a floor of a building
    - However, in some contexts "street level" can mean the ground floor
    - But looking at the example: "what level is the office on?" - this refers to which floor/story
    - The context says "walk out the window of the third floor onto street level" - this contrasts "third floor" with "street level"
    - So "street level" is not a floor/story of the building, but rather the height/elevation of the street

 Comparing sense 4 and sense 6:
 - Sense 4: "height above ground" - "the water reached ankle level"
 - Sense 6: "a flat surface at right angles to a plumb line" - "park the car on the level"

 "Street level" in the context means the level/height of the street relative to the ground. The woman walked from the third floor (elevated) down to the street height. This is about vertical position/height.

 Sense 4 seems best: "height above ground"
 - The example "the water reached ankle level" shows it refers to a specific height
 - "Street level" = the height of the street

 Sense 8 is about floors/stories of a building. While related, "street level" specifically refers to the ground elevation, not a building floor level (though ground floor is sometimes called street level).

 Actually, looking more carefully at sense 8: "a structure consisting of a room or set of rooms at a single position along a vertical scale" with synonyms "floor, storey, story".
 - "Street level" is not a structure with rooms. It's the outdoor ground level.

 Sense 6: "a flat surface at right angles to a plumb line" - this is the horizontal plane. "Park the car on the level" means on flat ground.
 - "Street level" could mean the horizontal plane of the street.

 But sense 4: "height above ground" - this seems to capture "street level" as a height measurement. The woman walked out onto the street height (ground level).

 Let me check the WordNet definitions more carefully.

 In WordNet 3.1 (which these keys likely reference):
 - level%1:07:01:: - height above ground; "the water reached ankle level"; "the pictures were at the same level"
 - level%1:06:03:: - a flat surface at right angles to a plumb line; "park the car on the level"

 The phrase "street level" typically means ground level - the level of the street surface.

 In the sentence: "walk out the window... onto street level" - this means she stepped from the window (which was now at ground height because the building sank) onto the street surface.

 Wait, reading the context again: "The house just settled right down into the ground."
 So the house sank into the ground due to liquefaction. The third floor became level with the street (ground level).

 So "street level" here means the height/elevation of the street.

 Between sense 4 (height above ground) and sense 8 (floor/story):
 - Sense 8 would imply "street level" is a floor of a building, like "ground floor"
 - But here "street level" means the elevation of the street itself

 Sense 4 "height above ground" with example "the water reached ankle level" - this refers to a specific height relative to ground.
 "Street level" = the level of the street = ground level = a specific height.

 Actually, looking at sense 6: synonym "horizontal surface"
 "Street level" could be interpreted as the horizontal plane of the street.

 But sense 4 seems more specific to the vertical position. The woman walked from the third floor down to ground height.

 Let me reconsider sense 8. Could "street level" be considered a "level" meaning floor/story?
 - "What level is the office on?" - asking which floor
 - But "street level" is not asking which floor of a building. It's referring to the ground elevation.

 Actually, in many WordNet annotations, "ground level" and "street level" are often tagged with sense 4 or sense 6 depending on whether it's emphasizing the height or the surface.

 But looking at the specific example for sense 4: "the water reached ankle level" - this is clearly about height.
 Example for sense 6: "park the car on the level" - this is about a flat horizontal surface.

 In our context: "walk out the window... onto street level"
 This is about reaching the height of the street (ground). It's about the vertical position.

 I think sense 4 is the best fit.

 But let me double-check if sense 8 could fit. Sense 8 is "floor, storey, story".
 - "Street level" is not a storey/floor of the building. It's the ground outside.
 - The text contrasts "third floor" with "street level".
 - "Street level" here means the level of the street, i.e., ground level.

 I think sense 4 is correct.

 Wait, I should also consider sense 6 more carefully. "A flat surface at right angles to a plumb line" - this is the definition of a horizontal plane, i.e., "level" as in "finding level (horizontal)".
 "Street level" = the level of the street = the horizontal plane of the street.

 But the example "park the car on the level" suggests sense 6 means "the level" as a noun phrase referring to horizontal ground. But "street level" is attributive - it modifies an implied "ground" or it's used as a location.

 Actually, "onto street level" - "level" here is a noun meaning "the level of the street", i.e., the height/elevation.

 Comparing the examples:
 - Sense 4: "ankle level", "same level" - these refer to heights
 - Sense 6: "on the level" - this refers to a flat horizontal surface

 "Street level" in "walk onto street level" - is it "walk onto the level surface of the street" or "walk onto [the ground at] the height of the street"?

 Given that the house "settled right down into the ground," the third floor ended up at the same height as the street. So the woman walked out onto the street surface, which was now at the same height as her window.

 Both sense 4 (height) and sense 6 (horizontal surface) could work, but sense 4 emphasizes the vertical position (height above ground), which fits the narrative of the house sinking from third floor height to ground height.

 Also, note that "street level" is a common collocation for ground level, and in WordNet, "ground level" might be classified under height.

 Let me check if there's any other sense I missed.

 Sense 3: "stage" - no
 Sense 2: "grade, tier" - no
 Sense 1: "degree, grade" - abstract level - no

 So it's between 4, 6, and 8.

 Sense 8 (floor/story): This is specifically for levels of a building. The text explicitly contrasts "third floor" with "street level", implying street level is NOT a floor of the building but rather the outside ground level. So sense 8 is incorrect.

 Between 4 and 6:
 Sense 4: height above ground
 Sense 6: horizontal surface

 "Street level" as a height: "The water is rising to street level" - this would be sense 4.
 "Street level" as a horizontal plane: "The laser creates a plane at street level" - this would be sense 6.

 In the walking context: "walk out onto street level" - she walked out onto the surface of the street (which is horizontal). But she walked out because the house sank to that height.

 Actually, looking at the WordNet hierarchy:
 Sense 4 (level%1:07:01) is under "attribute" -> "measure" -> "dimension" -> "elevation" -> "height"
 Sense 6 (level%1:06:03) is under "artifact" -> "surface" -> "horizontal surface"
 Sense 8 (level%1:06:01) is under "artifact" -> "structure" -> "construction" -> "building" -> "floor" etc.

 Given the context of liquefaction and the house settling into the ground, the key semantic component is the vertical positioning/height. The house moved from its original elevation to "street level" (ground level).

 I choose sense 4.

 Wait, I want to verify the sense keys. The format is level%1:XX:YY::
 1:07:00 - noun.attribute
 1:26:01 - noun.group
 1:26:00 - noun.state
 1:07:01 - noun.attribute (height)
 1:06:00 - noun.artifact (tool)
 1:06:03 - noun.artifact (horizontal surface)
 1:09:00 - noun.location (abstract)
 1:06:01 - noun.artifact (floor/story)

 Actually, looking up WordNet 3.0/3.1:
 - level%1:07:01:: is indeed "height above ground"
 - level%1:06:03:: is "a flat surface at right angles to a plumb line; 'park the car on the level'"

 In the sentence "walk out the window... onto street level", this is similar to "the water reached ankle level". It indicates a specific height.

 Also, "street level" is often synonymous with "ground level", and ground level is about elevation/height.

 Therefore, sense 4 (index 4 in the list, which corresponds to sense_key level%1:07:01::).

 Wait, the question asks for the "single best indexed sense" and the candidates are numbered 1-8. I need to return the index number.

 The candidates are:
 1. sense_key=level%1:07:00::
 2. sense_key=level%1:26:01::
 3. sense_key=level%1:26:00::
 4. sense_key=level%1:07:01::
 5. sense_key=level%1:06:00::
 6. sense_key=level%1:06:03::
 7. sense_key=level%1:09:00::
 8. sense_key=level%1:06:01::

 So sense 4 is the fourth one in the list.

 But I want to reconsider sense 6 one more time. "Park the car on the level" - here "the level" means level ground, a horizontal surface.
 "Onto street level" - could mean onto the flat surface of the street.

 However, given the context of the earthquake and liquefaction, the narrative focuses on the vertical displacement - the house sank so the third floor was at ground height. The "height" sense captures this better than the "horizontal surface" sense.

 Also, "ankle level" from sense 4's examples is analogous to "street level" - both specify a height relative to the ground.

 So I will go with index 4.

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

Context analysis:
- The text describes an earthquake scenario in San Francisco (Marina district)
- It mentions a "three-story apartment" and then "The house just settled right down into the ground"
- This is describing a physical building that settled into the ground due to liquefaction during an earthquake
- The "house" here refers to the physical dwelling/building

Looking at the candidate senses:

1. house%1:06:00:: - a dwelling that serves as living quarters for one or more families (examples: he has a house on Cape Cod; she felt she had to get out of the house)
   - This fits well. It's a physical dwelling where people live. The context mentions it settled into the ground, which applies to a physical building used as living quarters.

2. house%1:14:01:: - business organization (brokerage house) - doesn't fit

3. house%1:14:04:: - religious community - doesn't fit

4. house%1:14:03:: - theatre audience - doesn't fit

5. house%1:14:02:: - legislative assembly - doesn't fit

6. house%1:14:00:: - aristocratic family line - doesn't fit

7. house%1:04:00:: - children's play - doesn't fit

8. house%1:15:00:: - astrology - doesn't fit

9. house%1:14:06:: - gambling management - doesn't fit

10. house%1:14:05:: - social unit/family (synonyms: family, household) - while related, the context emphasizes the physical structure settling into the ground, not the social unit. The phrase "settled right down into the ground" strongly suggests the physical building.

11. house%1:06:02:: - theatre building - doesn't fit (though it's a building, the context is residential)

12. house%1:06:01:: - a building in which something is sheltered or located (examples: carriage house) - this is more general, but sense 1 is more specific for a dwelling.

Between sense 1 and sense 12:
- Sense 1: dwelling for families (residential house)
- Sense 12: general building for sheltering something

The context mentions "apartment" earlier and describes a residential scenario ("A woman in a three-story apartment"), so sense 1 (dwelling for families) is the best fit. The word "house" here is being used to refer to the building/structure that settled into the ground due to the earthquake and liquefaction.

The index for sense 1 is: 1

Wait, looking at the list:
1. sense_key=house%1:06:00::
2. sense_key=house%1:14:01::
3. sense_key=house%1:14:04::
4. sense_key=house%1:14:03::
5. sense_key=house%1:14:02::
6. sense_key=house%1:14:00::
7. sense_key=house%1:04:00::
8. sense_key=house%1:15:00::
9. sense_key=house%1:14:06::
10. sense_key=house%1:14:05::
11. sense_key=house%1:06:02::
12. sense_key=house%1:06:01::

But let me double-check if it could be sense 12. Sense 12 is "a building in which something is sheltered or located" with example "carriage house". This is more general and typically used for outbuildings or specific types of buildings, not primary dwellings.

Sense 1 is clearly the best fit: "a dwelling that serves as living quarters for one or more families". The context describes a residential building (apartment/house) settling into the ground during an earthquake.

Therefore, the correct index is 1.

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

Context analysis:
- The text is about an earthquake in San Francisco (Marina district).
- "Areas that are made of 'fill' liquefy."
- "A woman in a three-story apartment was able to walk out the window of the third floor onto street level after the quake."
- "The house just settled right down into the <t>ground</t>."

So the house settled down into the ground. This refers to the solid surface of the earth, or the earth's surface. The house sank into the earth/ground.

Let's look at the candidate senses:

1. ground%1:17:00:: | definition=the solid part of the earth's surface | synonyms=land, dry land, earth, solid ground, terra firma | examples=the plane turned away from the sea and moved back over land; the earth shook for several minutes
- This seems like a strong candidate. The house settled into the solid part of the earth's surface. "solid ground" is a synonym.

2. ground%1:16:00:: | definition=a rational motive for a belief or action | synonyms=reason
- Not relevant.

3. ground%1:27:00:: | definition=the loose soft material that makes up a large part of the land surface | synonyms=earth | examples=they dug into the earth outside the church
- This refers to loose soft material (soil/dirt). The house settled into the ground. Could this work? Yes, but sense 1 seems more about the solid surface. However, in earthquakes, fill/liquefaction causes buildings to sink into the soil. But the phrase "settled right down into the ground" suggests sinking into the earth's surface.

4. ground%1:24:00:: | definition=a relation that provides the foundation for something | synonyms=footing, basis
- Abstract, not relevant.

5. ground%1:15:00:: | definition=a position to be won or defended in battle
- Not relevant.

6. ground%1:09:00:: | definition=the part of a scene (or picture) that lies behind objects in the foreground
- Not relevant.

7. ground%1:17:01:: | definition=material in the top layer of the surface of the earth in which plants can grow (especially with reference to its quality or use) | synonyms=land, soil
- This is specifically about soil for growing plants. The context is about a house sinking after an earthquake, not agricultural soil.

8. ground%1:09:01:: | definition=a relatively homogeneous percept extending back of the figure on which attention is focused
- Figure-ground, not relevant.

9. ground%1:06:02:: | definition=electrical ground
- Not relevant.

10. ground%1:06:01:: | definition=(art) the surface prepared to take the paint
- Not relevant.

11. ground%1:06:00:: | definition=the first or preliminary coat of paint
- Not relevant.

So it's between sense 1 and sense 3 (and maybe 7).

Sense 1: "the solid part of the earth's surface" - synonyms include land, dry land, earth, solid ground, terra firma. Examples: "the plane turned away from the sea and moved back over land", "the earth shook for several minutes". This is the earth as opposed to sea/air. The house settled into the ground (as opposed to being above it). This fits well.

Sense 3: "the loose soft material that makes up a large part of the land surface" - synonyms=earth. Examples: "they dug into the earth outside the church". This is more like dirt/soil. If a house settles into the ground, it could be sinking into the soil. But the phrase "solid ground" is often used. Also, the context mentions "fill" and liquefaction - where solid ground becomes fluid-like. But the sentence says "the house just settled right down into the ground." This is a common idiom/expression.

Let's check WordNet more carefully. In WordNet, sense 1 (ground%1:17:00::) is the solid part of the earth's surface. Sense 3 (ground%1:27:00::) is the loose soft material... which is basically soil/dirt. Sense 7 (ground%1:17:01::) is material in the top layer... in which plants can grow (soil/land).

In the context of a house settling "into the ground", we usually mean the earth's surface. "Ground" here is contrasted with the house being elevated. After the quake, it settled to ground level or into the ground. The example in sense 1 includes "the earth shook for several minutes" which is earthquake-related, making it very relevant. The synonyms "solid ground" and "earth" fit perfectly.

Sense 3's example "they dug into the earth" suggests excavation into loose material. While a house could sink into loose material, the more general and common sense for "settled into the ground" is sense 1. Also, the context mentions "street level" and "the house just settled right down into the ground" - this parallels "solid ground" (as in the building coming to rest on/sinking into the solid earth).

Wait, actually, if the ground liquefied, it's not solid. But the word "ground" itself in this context refers to the earth's surface. The fact that it liquefied is a property, but the word "ground" still denotes the earth's surface.

Let me reconsider sense 3. "the loose soft material that makes up a large part of the land surface". In the Marina district, the fill is loose soft material. The house settled into it. But WordNet sense 3 is hypernymed under "material, stuff" (1:27). Sense 1 is under "object, physical object" (1:17) - the solid part of the earth's surface.

Actually, looking at the sentence: "The house just settled right down into the ground." If I replace "ground" with synonyms:
- into the land / dry land / earth / solid ground / terra firma (sense 1) -> "settled into the earth" works, "settled into the land" works, "settled into solid ground" works.
- into the loose soft material (sense 3) -> "settled into the earth" (sense 3 synonym) also works.

But sense 1 has the earthquake example "the earth shook for several minutes". This strongly suggests sense 1 is the right domain. Also, "ground" in the sense of "earth's surface" is the most frequent sense.

Let me check if there's any subtlety. The woman walked out onto street level. The house settled into the ground. This means the ground level remained the same or the house sank. "Ground" here means the surface of the earth. That's sense 1.

Sense 7 is specifically about material for growing plants. Not right.

Therefore, the best sense is sense 1.

Wait, I need to make sure about the indexing. The user lists:
1. sense_key=ground%1:17:00::
2. sense_key=ground%1:16:00::
3. sense_key=ground%1:27:00::
4. sense_key=ground%1:24:00::
5. sense_key=ground%1:15:00::
6. sense_key=ground%1:09:00::
7. sense_key=ground%1:17:01::
8. sense_key=ground%1:09:01::
9. sense_key=ground%1:06:02::
10. sense_key=ground%1:06:01::
11. sense_key=ground%1:06:00::

So sense_index should be 1.

Double-check: Is there any chance it's sense 3? "the loose soft material that makes up a large part of the land surface". The house settled into the loose soft material (fill). But the definition says "loose soft material that makes up a large part of the land surface". That's basically soil. But when we say a house sinks into the ground, we don't typically conceptualize it as sinking into "loose soft material" unless specified. We conceptualize it as sinking into the earth/surface. The WordNet example for sense 1 includes "the earth shook for several minutes" which is directly earthquake-related. This is a strong indicator that sense 1 is the correct WordNet sense for this context.

Also, "solid ground" in the synonyms of sense 1 is antonymous with the liquefied ground in the context, but still the same lexical item.

I will go with sense_index: 1.

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

 Context analysis:
 - "I was driving my truck, stopped at a red light at the corner of Shattuck and Alcatraz at the Oakland-Berkeley border when it hit."
 - The speaker is operating/controlling a vehicle (truck).
 - They were stopped at a red light.
 - Later mentions "no way to drive away" which also relates to operating the vehicle.

 Candidate sense analysis:
 1. sense_key=drive%2:38:01:: | definition=operate or control a vehicle | examples=drive a car or bus; Can you drive this four-wheel truck?
    - This fits perfectly. The person is operating/controlling their truck.

 2. sense_key=drive%2:38:00:: | definition=travel or be transported in a vehicle | synonyms=motor | examples=We drove to the university every morning
    - This is about traveling/being transported, but the context emphasizes the act of operating the truck ("driving my truck") rather than just traveling.

 3. sense_key=drive%2:38:02:: | definition=cause someone or something to move by driving | examples=She drove me to school every day
    - This is about causing movement, but the context is about the speaker operating their own vehicle.

 4. sense_key=drive%2:35:00:: | definition=force into or from an action or state...
    - Not relevant here.

 5. sense_key=drive%2:41:02:: | definition=to compel or force...
    - Not relevant.

 6-22. Other senses are about hunting, golf, pushing, etc. - not relevant.

 The key distinction is between sense 1 (operate/control) and sense 2 (travel/transport).

 In the sentence "I was driving my truck", the focus is on the operation/control of the vehicle. The examples for sense 1 include "drive a car or bus" and "Can you drive this four-wheel truck?" which matches "driving my truck" perfectly.

 Sense 2 examples: "We drove to the university" - this focuses on the transportation aspect, not necessarily the operation aspect (though they overlap).

 Also, sense 13: "work as a driver" - this is about profession, not the specific act described.

 Sense 16: "proceed along in a vehicle" - "We drive the turnpike to work" - this is about traveling along a route.

 The most accurate sense is sense 1: operate or control a vehicle.

 Wait, let me check sense 2:38:00 vs 2:38:01 again.

 Sense 2:38:01: "operate or control a vehicle" - examples: "drive a car or bus; Can you drive this four-wheel truck?"
 Sense 2:38:00: "travel or be transported in a vehicle" - examples: "We drove to the university every morning"

 In the context: "I was driving my truck" - this clearly indicates operating/controlling the vehicle. The mention of "my truck" and being stopped at a red light indicates the person is in control of the vehicle.

 Therefore, sense 1 (index 1) is the correct choice.

 Wait, I need to check if there's any other sense that might fit better.

 Sense 14: "move by being propelled by a force" - "The car drove around the corner" - this is intransitive, but here we have transitive "driving my truck".

 Sense 12: "have certain properties when driven" - "This car rides smoothly" - not relevant.

 So yes, sense 1 is the best fit.

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

 Note: The sense keys are labeled with indices 1-22 in the list provided. So "sense_key=drive%2:38:01::" corresponds to index 1 in the list.

 Let me verify the mapping:
 1. sense_key=drive%2:38:01::
 2. sense_key=drive%2:38:00::
 3. sense_key=drive%2:38:02::
 ...

 Yes, so the answer is index 1.

Context analysis:
- The speaker is describing driving a vehicle: "I was driving my truck, stopped at a red light..."
- This indicates a motorized vehicle that can be driven on streets
- The context mentions driving, red lights, streets (Shattuck and Alcatraz), and the Oakland-Berkeley border
- This is clearly referring to an automotive vehicle

Candidate senses:
1. truck%1:06:00:: - an automotive vehicle suitable for hauling (motortruck)
2. truck%1:06:01:: - a handcart/hand truck with two low wheels, used to move crates

Evaluation:
- Sense 1 fits perfectly: The person was driving it, stopped at a red light, on a street. This is clearly a motorized truck (pickup truck, semi-truck, etc.).
- Sense 2 is a manual hand truck/dolly used for moving heavy objects - this cannot be "driven" in the sense of being operated on public roads at traffic lights.

Therefore, sense index 1 is the correct choice.

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

 Context analysis:
 - The sentence is: "I was driving my truck, stopped at a red light at the corner of Shattuck and Alcatraz at the Oakland-Berkeley border when it hit."
 - The subject is driving a truck and stopped at a red light.
 - This describes the action of bringing the vehicle to a halt because of a traffic light.

 Candidate sense analysis:
 1. sense_key=stop%2:38:00:: | definition=come to a halt, stop moving | synonyms=halt | examples=the car stopped; She stopped in front of a store window
    - This is an intransitive use: the subject stops moving.
    - The example "the car stopped" matches perfectly.
    - In the context, the truck (implied subject) stopped at a red light.

 2. sense_key=stop%2:42:00:: | definition=put an end to a state or an activity | synonyms=discontinue, cease, give up, quit, lay off
    - This is about ceasing an activity, not physically halting motion.

 3. sense_key=stop%2:41:00:: | definition=stop from happening or developing
    - This is transitive: preventing something from happening.

 4. sense_key=stop%2:38:02:: | definition=interrupt a trip | synonyms=stop over | examples=we stopped at Aunt Mary's house; they stopped for three days in Florence
    - This implies a temporary pause during a journey, often for a visit or stay.
    - While the truck did stop, this sense usually implies a longer duration or a visit, not just halting at a traffic light. The examples suggest stopping at a location for a purpose (visiting, staying).

 5. sense_key=stop%2:38:01:: | definition=cause to stop | examples=stop a car; stop the thief
    - This is transitive: causing something else to stop. Here the subject is the one stopping (intransitive).

 6. sense_key=stop%2:30:05:: | definition=prevent completion
    - Not relevant here.

 7. sense_key=stop%2:33:00:: | definition=hold back, as of a danger or an enemy
    - Not relevant.

 8. sense_key=stop%2:35:00:: | definition=seize on its way
    - Not relevant.

 9. sense_key=stop%2:42:13:: | definition=have an end, in a temporal, spatial, or quantitative sense
    - This is about termination/end points, not the act of halting motion.

 10. sense_key=stop%2:35:12:: | definition=render unsuitable for passage
    - This is about blocking/barricading.

 11. sense_key=stop%2:30:12:: | definition=stop and wait, as if awaiting further instructions
    - This could be close, but sense 1 is more specific to halting movement.

 The best fit is sense 1: "come to a halt, stop moving". The truck came to a halt at the red light. This is the intransitive sense of ceasing to move.

 The context "stopped at a red light" clearly indicates the vehicle ceased moving.

 Sense 4 (interrupt a trip) is possible but usually implies a deliberate stop for a purpose (visiting, resting), whereas stopping at a traffic light is a mandatory halt in traffic flow. The examples for sense 4 ("stopped at Aunt Mary's house", "stopped for three days") suggest a different kind of stopping than a traffic light.

 Therefore, sense 1 is the correct choice.

 The user wants me to perform Word Sense Disambiguation for the target lemma "red_light" with the surface form "red light" in the given context.

 Context analysis:
 - The sentence is: "I was driving my truck, stopped at a <t>red light</t> at the corner of Shattuck and Alcatraz at the Oakland-Berkeley border when it hit."
 - The speaker is describing driving a truck and stopping at a red light (traffic signal) when an earthquake hit.
 - The phrase "stopped at a red light" strongly suggests a traffic signal indicating when vehicles must stop.

 Candidate senses:
 1. sense_key=red_light%1:10:01:: | definition=a cautionary sign of danger | synonyms=warning light
 2. sense_key=red_light%1:10:00:: | definition=the signal to stop

 Analysis:
 - Sense 2 ("the signal to stop") fits the context of traffic lights where drivers stop at red lights. This is the standard meaning of a red traffic light.
 - Sense 1 ("a cautionary sign of danger") is more general and could apply to warning lights in various contexts, but the specific context of driving and stopping at an intersection points to the traffic signal meaning.
 - The phrase "stopped at a red light" is an extremely common collocation referring to traffic signals.
 - While an earthquake is dangerous (which might suggest sense 1), the immediate context is about the traffic control device that indicates when to stop.

 Therefore, sense 2 (red_light%1:10:00::) is the correct choice.

 The user wants the output as a JSON object: {"sense_index": 2}

 Wait, looking at the candidate senses:
 1. sense_key=red_light%1:10:01::
 2. sense_key=red_light%1:10:00::

 So sense_index should be 2 for the second one (the signal to stop).

 Let me double-check WordNet senses for red_light:
 - red_light%1:10:00:: usually refers to the traffic signal meaning "stop"
 - red_light%1:10:01:: usually refers to a warning light/danger sign

 Yes, in WordNet:
 - red_light#1: the signal to stop (traffic light)
 - red_light#2: a cautionary sign of danger

 The context clearly involves a traffic intersection ("corner of Shattuck and Alcatraz") and driving a truck, so it's definitely the traffic signal sense.

 Therefore: {"sense_index": 2}

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

 Context: "I was driving my truck, stopped at a red light at the <t>corner</t> of Shattuck and Alcatraz at the Oakland-Berkeley border when it hit."

 The target is referring to the intersection of two streets: Shattuck and Alcatraz.

 Let me look at the candidate senses:

 1. sense_key=corner%1:15:02:: - "a place off to the side of an area" - examples mention rightfield corner, southeastern corner of Mediterranean. This seems like a general area, not specifically streets.

 2. sense_key=corner%1:15:00:: - "the point where two lines meet or intersect" - geometric sense.

 3. sense_key=corner%1:06:02:: - "an interior angle formed by two meeting walls" - synonyms: nook. This is about rooms/buildings interior.

 4. sense_key=corner%1:06:00:: - "the intersection of two streets" - synonyms: street corner, turning point. Examples: "standing on the corner watching all the girls go by". This matches perfectly - Shattuck and Alcatraz are street names.

 5. sense_key=corner%1:15:01:: - "the point where three areas or surfaces meet or intersect" - like a cube corner.

 6. sense_key=corner%1:25:00:: - "a small concavity" - recess, niche.

 7. sense_key=corner%1:26:00:: - "a temporary monopoly on a kind of commercial trade" - financial sense.

 8. sense_key=corner%1:26:01:: - "a predicament from which a skillful or graceful escape is impossible" - metaphorical.

 9. sense_key=corner%1:17:00:: - "a projecting part where two sides or edges meet" - physical object corners.

 10. sense_key=corner%1:15:03:: - "a remote area" - distant places.

 11. sense_key=corner%1:06:01:: - "(architecture) solid exterior angle of a building; especially one formed by a cornerstone" - quoin.

 The context clearly describes an intersection of two specific streets: Shattuck and Alcatraz. The phrase "corner of Shattuck and Alcatraz" is a classic example of the street intersection sense.

 Sense 4 (index 4 in the list, but I need to check the indexing) is:
 sense_key=corner%1:06:00:: | definition=the intersection of two streets | synonyms=street corner, turning point | examples=standing on the corner watching all the girls go by

 This is clearly the best match. The user asks for the "sense_index" which appears to be the number in the list (1-indexed).

 So the answer should be: {"sense_index": 4}

 Wait, let me double-check the indexing. The candidates are numbered 1 through 11. So sense 4 is the one with "the intersection of two streets".

 Yes, index 4.

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

 Context analysis:
 - The text is describing an earthquake ("Areas that are made of 'fill' liquefy", "the quake", "power lines waving")
 - The specific sentence: "I was driving my truck, stopped at a red light at the corner of Shattuck and Alcatraz at the Oakland-Berkeley border when it hit."
 - "It" refers to the earthquake.
 - The meaning here is that the earthquake struck or occurred suddenly.

 Looking at the candidate senses:

 1. hit%2:35:03:: - cause to move by striking (e.g., hit a ball) - This doesn't fit. The earthquake isn't causing something else to move by striking in this context.

 2. hit%2:35:01:: - hit against; come into sudden contact with (synonyms: strike, impinge on, run into, collide with) - This could work. The earthquake "hit" meaning it struck or came into sudden contact with the area. But let's check others.

 3. hit%2:35:00:: - deal a blow to (with hand or instrument) - This implies a physical blow from a person, not quite right for an earthquake.

 4. hit%2:38:00:: - reach a destination - No, the earthquake isn't reaching a destination in this sense.

 5. hit%2:35:05:: - affect or afflict suddenly, usually adversely (synonyms: strike) - Examples: "We were hit by really bad weather", "He was stricken with cancer". This fits well. The earthquake "hit" meaning it affected/afflicted the area suddenly and adversely.

 6. hit%2:33:01:: - hit with a missile from a weapon - No.

 7. hit%2:40:05:: - encounter by chance - No.

 8. hit%2:33:02:: - gain points in a game - No.

 9. hit%2:39:00:: - cause to experience suddenly (synonyms: strike, come to) - Examples: "Panic struck me", "An interesting idea hit her". This is about ideas or feelings hitting someone. The earthquake is an external event, not an idea or feeling.

 10. hit%2:33:00:: - make a strategic offensive assault - No.

 11. hit%2:41:00:: - kill intentionally - No.

 12. hit%2:38:02:: - drive something violently into a location - No.

 13. hit%2:38:07:: - reach a point in time or state - No.

 14. hit%2:35:02:: - produce by manipulating keys/strings - No.

 15. hit%2:34:00:: - consume to excess - No.

 16. hit%2:33:03:: - hit the intended target - No.

 17. hit%2:32:12:: - pay unsolicited sexual attention - No.

 Now comparing sense 2 and sense 5:

 Sense 2: "hit against; come into sudden contact with" - This is more physical contact between objects. The car hit a tree. He struck the table.

 Sense 5: "affect or afflict suddenly, usually adversely" - This is about being affected by something bad. We were hit by bad weather. The area was hit by an earthquake.

 In the context of natural disasters like earthquakes, "hit" is typically used in the sense of "affect or afflict suddenly, usually adversely" (sense 5). The earthquake "hit" the area means it struck the area and affected it adversely.

 However, looking at the specific sentence: "when it hit" - "it" refers to the earthquake. The earthquake hit (struck) while the person was driving.

 Sense 2 could also work: "The earthquake hit" could mean it came into sudden contact with the ground/area.

 But sense 5 is more specific to adverse events affecting a location: "We were hit by really bad weather" is analogous to "we were hit by the earthquake" or "the earthquake hit."

 Actually, looking at WordNet examples for sense 2: "The car hit a tree" - physical collision.
 For sense 5: "We were hit by really bad weather" - being affected by something.

 In "when it hit", where "it" is the earthquake, both could potentially work, but sense 5 (affect or afflict suddenly, usually adversely) is the standard sense for disasters "hitting" a place.

 Wait, let me reconsider sense 9: "cause to experience suddenly" - "Panic struck me", "An interesting idea hit her". This is about the subject experiencing something. But here "it" (the earthquake) is the subject hitting, not the object of experience.

 Actually, looking at the structure: "when it hit" - the earthquake is doing the hitting. In sense 9, the structure is usually "an idea hit me" (where "me" experiences the idea). But for earthquakes, we say "the earthquake hit" meaning it struck/affected the area.

 Let me look at sense 2 again: "hit against; come into sudden contact with" - synonyms include "strike". "The earthquake struck" is common.

 But sense 5 specifically mentions "affect or afflict suddenly, usually adversely" with example "We were hit by really bad weather". This is the sense used when talking about disasters affecting areas.

 However, there's a subtle difference. In "when it hit", the earthquake itself is the agent. In "we were hit by...", people are the object.

 But "the earthquake hit" is intransitive or transitive? "When it hit" - intransitive use? Or "when it hit [the area]"?

 Actually, looking at the context: "I was driving... when it hit." This is similar to "when the earthquake struck."

 Between sense 2 (strike, collide) and sense 5 (affect adversely):

 Sense 2 is more about physical impact/collision.
 Sense 5 is more about being affected by something negative.

 For earthquakes, both senses could apply, but sense 5 is specifically for "affect or afflict suddenly, usually adversely" which matches natural disasters perfectly.

 But wait, looking at the WordNet sense keys:
 - hit%2:35:01:: is "hit against; come into sudden contact with"
 - hit%2:35:05:: is "affect or afflict suddenly, usually adversely"

 The example for sense 5 is "We were hit by really bad weather" - passive voice, emphasizing being affected.
 The examples for sense 2 are active: "The car hit a tree", "He struck the table".

 In "when it hit", "it" (earthquake) is the subject. Earthquakes can "hit" in the sense of physical striking (sense 2) or affecting adversely (sense 5).

 However, looking at standard WSD for "hit" in the context of earthquakes:
 - "The earthquake hit the city" - usually sense 5 (affect adversely) or sense 2 (strike).

 But let's look at the specific index numbers. The user lists them as:
 1. sense_key=hit%2:35:03::
 2. sense_key=hit%2:35:01::
 3. sense_key=hit%2:35:00::
 4. sense_key=hit%2:38:00::
 5. sense_key=hit%2:35:05::
 ...

 So sense 5 in the list corresponds to hit%2:35:05::.

 Actually, looking carefully at the list:
 1. hit%2:35:03::
 2. hit%2:35:01::
 3. hit%2:35:00::
 4. hit%2:38:00::
 5. hit%2:35:05::
 ...

 So index 5 is hit%2:35:05:: "affect or afflict suddenly, usually adversely".

 Index 2 is hit%2:35:01:: "hit against; come into sudden contact with".

 Which is better?

 In the context of the earthquake narrative, "when it hit" means when the earthquake struck/when it occurred and affected the area. The sense "affect or afflict suddenly, usually adversely" captures the meaning of a disaster hitting a location.

 However, "hit against; come into sudden contact with" (sense 2) is also plausible as it describes the physical event of the earthquake waves hitting the ground.

 But looking at the examples:
 - Sense 2: "The car hit a tree" - concrete physical objects colliding
 - Sense 5: "We were hit by really bad weather" - abstract or natural phenomena affecting people

 An earthquake is a natural phenomenon like weather. So sense 5 seems more appropriate.

 Also, sense 2 often implies a more direct physical collision between solid objects, while sense 5 is used for disasters, diseases, etc.

 Therefore, sense 5 (index 5) is the best choice.

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

 Sense 9: "cause to experience suddenly" - "An interesting idea hit her". This is for mental/emotional experiences, not physical events like earthquakes.

 Sense 10: "make a strategic offensive assault" - military context.

 So it's between 2 and 5.

 Given the context of a natural disaster (earthquake) affecting an area, and the parallel with "We were hit by really bad weather", sense 5 is the best fit.

 Final check: The sentence is "when it hit" referring to the earthquake. In common parlance, we say "the earthquake hit" meaning it struck the area and caused damage/effects. This is sense 5.

 Answer: {"sense_index": 5}

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

 Context analysis:
 The sentence is: "Worst <t>part</t> was watching power lines waving above my head and no way to drive away."

 This is describing the experience of being in an earthquake. The speaker says the "worst part" was watching power lines waving above their head with no way to drive away.

 This seems to refer to a segment, section, or aspect of the overall experience. It's referring to one portion of the earthquake experience that was particularly bad.

 Let's look at the candidate senses:

 1. part%1:24:00:: - something determined in relation to something that includes it (portion, component part)
    - Example: "he wanted to feel a part of something bigger than himself"
    - This is about being a component of a larger whole.

 2. part%1:06:00:: - something less than the whole of a human artifact
    - Example: "the rear part of the house"
    - Physical part of an object.

 3. part%1:17:00:: - a portion of a natural object
    - Example: "they analyzed the river into three parts"
    - Physical part of a natural thing.

 4. part%1:09:02:: - that which concerns a person with regard to a particular role or situation
    - Example: "it requires vigilance on our part"
    - This is about one's responsibility or involvement.

 5. part%1:15:00:: - the extended spatial location of something
    - Example: "religions in all parts of the world"
    - Geographic/spatial region.

 6. part%1:04:01:: - the actions and activities assigned to or required or expected of a person or group
    - Example: "the function of a teacher"
    - Role/duty.

 7. part%1:09:01:: - an actor's portrayal of someone in a play
    - Example: "she played the part of Desdemona"
    - Acting role.

 8. part%1:21:00:: - assets belonging to or due to or contributed by an individual person or group
    - Example: "he wanted his share in cash"
    - Financial share.

 9. part%1:09:00:: - one of the portions into which something is regarded as divided and which together constitute a whole
    - Example: "the written part of the exam"
    - Section/division of a whole (abstract or concrete).

 10. part%1:08:01:: - a line of scalp...
     - Hair parting.

 11. part%1:10:00:: - musical part/voice.
     - Music.

 12. part%1:04:03:: - the part played by a person in bringing about a result
     - Example: "I am proud of my contribution"
     - Contribution to an outcome.

 Now, analyzing "Worst part was watching power lines...":

 This is referring to a segment or aspect of the earthquake experience. It's describing one component of the whole event that was particularly bad.

 Sense 9 (part%1:09:00::) seems most appropriate: "one of the portions into which something is regarded as divided and which together constitute a whole" with examples like "the written part of the exam."

 The "worst part" refers to the worst aspect/segment/portion of the experience.

 Sense 1 is also close: "something determined in relation to something that includes it" - but this seems more about being a constituent element in a physical or structural sense.

 Sense 9 specifically mentions "one of the portions into which something is regarded as divided" which fits well with "the worst part [of the experience]".

 Actually, looking at sense 1 again: "something determined in relation to something that includes it" - examples include "he wanted to feel a part of something bigger" and "I read a portion of the manuscript".

 But sense 9: "one of the portions into which something is regarded as divided and which together constitute a whole" - examples: "the written part of the exam; the finance section of the company".

 The phrase "worst part" is idiomatically referring to the most unpleasant aspect or segment of an experience. This aligns with sense 9, which deals with portions into which something is divided.

 However, let me check sense 1 more carefully. The definition is "something determined in relation to something that includes it". The examples are "he wanted to feel a part of something bigger than himself" and "I read a portion of the manuscript".

 Sense 9: "one of the portions into which something is regarded as divided and which together constitute a whole". Examples: "the written part of the exam; the finance section of the company".

 "Worst part" is referring to a segment of the earthquake experience. It's the worst section/aspect of it.

 Actually, looking at WordNet structure, sense 9 (part%1:09:00::) is often used for "part" meaning a section or division of a whole (like part 1 of a movie, the hard part of a task, etc.).

 Sense 1 (part%1:24:00::) is more about being a component or constituent of something.

 In "the worst part", we're talking about a segment of the experience. This is sense 9.

 Let me verify with similar constructions:
 - "the funny part is..."
 - "the best part of the movie"
 - "the hard part"

 These typically map to sense 9 in WordNet: "one of the portions into which something is regarded as divided..."

 Actually, looking at the examples for sense 9: "the written part of the exam; the finance section of the company" - these are clearly divisions of a whole.

 For sense 1: "he wanted to feel a part of something bigger than himself; I read a portion of the manuscript" - these are about being a piece of something larger.

 In "worst part was watching...", "part" refers to an aspect or segment of the earthquake experience. This is definitely sense 9.

 Wait, I should check if sense 4 applies: "that which concerns a person with regard to a particular role or situation" - example "it requires vigilance on our part". This is about personal involvement/responsibility. Not fitting.

 Sense 12: "the part played by a person in bringing about a result" - about contribution. Not fitting.

 So it's between 1 and 9 mostly.

 Sense 1: subsenses include component, constituent, portion, part of a whole (physical or abstract).
 Sense 9: section, division - a portion that is one of several making up a whole.

 "Worst part" = the worst section/aspect. This is sense 9.

 In WordNet, sense 9 is the abstract division sense, while sense 1 is the more general relation-to-whole sense. But sense 9 is specifically: "one of the portions into which something is regarded as divided and which together constitute a whole".

 Yes, "the worst part of the earthquake" = the worst segment/division of the whole event.

 Therefore, the answer is sense_index: 9.

 Wait, I need to be careful. The sense_key for sense 9 is part%1:09:00::, so the index would be 9.

 But let me double-check the indexing. The user lists:
 1. sense_key=part%1:24:00::
 2. sense_key=part%1:06:00::
 3. sense_key=part%1:17:00::
 4. sense_key=part%1:09:02::
 5. sense_key=part%1:15:00::
 6. sense_key=part%1:04:01::
 7. sense_key=part%1:09:01::
 8. sense_key=part%1:21:00::
 9. sense_key=part%1:09:00::
 10. sense_key=part%1:08:01::
 11. sense_key=part%1:10:00::
 12. sense_key=part%1:04:03::

 So index 9 corresponds to sense_key part%1:09:00::.

 Definition: "one of the portions into which something is regarded as divided and which together constitute a whole"

 This is correct for "the worst part [of the experience]".

 I should confirm that this isn't sense 1. Sense 1 is "something determined in relation to something that includes it". This is very general. But sense 9 is more specific to being a division/section of a whole.

 In WSD for "part", "the worst part" usually maps to the "section/division" sense (sense 9 here) rather than the "component/constituent" sense (sense 1).

 Example: "the best part of the trip" = the best section/portion of the trip.

 Yes, I'm confident it's sense 9.
