The user wants me to perform Word Sense Disambiguation for the target word "lost" (past participle of "lose") based on the provided context.

Context: "For months the Johns Hopkins researchers, using gene probes, experimentally crawled down the length of chromosome 17, looking for the smallest common bit of genetic material <t>lost</t> in all tumor cells. Such a piece of DNA would probably constitute a gene."

Target word: lost (in the phrase "genetic material lost in all tumor cells")

Analysis of the context:
The context is highly scientific, dealing with genetics, chromosomes, and tumor cells. The researchers are looking for a specific piece of genetic material (DNA) that is missing or absent in all tumor cells compared to a baseline (implied, likely normal cells).

Let's examine the candidate senses:

1. sense_key=lose%2:40:02:: | definition=fail to keep or to maintain; cease to have, either physically or in an abstract sense | Examples: She lost her purse... (Relates to possession/existence)
2. sense_key=lose%2:33:00:: | definition=fail to win | (Irrelevant - competition)
3. sense_key=lose%2:37:00:: | definition=suffer the loss of a person through death or removal | (Irrelevant - people)
4. sense_key=lose%2:35:00:: | definition=place (something) where one cannot find it again | synonyms=misplace, mislay | (Relates to misplacement, not biological absence)
5. sense_key=lose%2:40:01:: | definition=miss from one's possessions; lose sight of | (Relates to physical objects/sight)
6. sense_key=lose%2:39:00:: | definition=allow to go out of sight | (Irrelevant - allowing movement)
7. sense_key=lose%2:40:06:: | definition=fail to make money in a business; make a loss or fail to profit | (Irrelevant - finance)
8. sense_key=lose%2:40:00:: | definition=fail to get or obtain | (Relates to acquisition, but the context implies absence/deletion, not failure to obtain)
9. sense_key=lose%2:33:01:: | definition=retreat | (Irrelevant - movement)
10. sense_key=lose%2:39:01:: | definition=fail to perceive or to catch with the senses or the mind | synonyms=miss | (Relates to perception, not biological presence/absence)
11. sense_key=lose%2:30:03:: | definition=be set at a disadvantage | (Irrelevant - disadvantage)

The phrase "genetic material lost in all tumor cells" means that this specific piece of DNA is absent or has been deleted/removed from the tumor cells.

Sense 1: "fail to keep or to maintain; cease to have, either physically or in an abstract sense." This perfectly captures the idea of genetic material ceasing to exist or being absent from the cells.

Sense 8: "fail to get or obtain." While related to absence, Sense 1 is broader and better fits the biological concept of something being missing or no longer present (ceasing to have).

Sense 1 is the most appropriate fit for the biological context of genetic deletion/absence.

Final check:
Context: "genetic material lost in all tumor cells."
Sense 1: "cease to have, either physically or in an abstract sense."
This matches the concept of a piece of DNA being physically absent from the cells.

Matching the context:
The context explicitly links "cells" to "tumor," "gene losses," "colon cancer," and "genetic material." This strongly points to the biological definition of a cell.

Sense 2: "(biology) the basic structural and functional unit of all organisms..." perfectly matches the context of cancer research and tumor biology.

Conclusion: Sense 2 is the best fit.

The word "piece" refers to a small segment of DNA.

13. sense_key=piece%1:06:02:: | definition=game equipment consisting of an object used in playing certain board games | synonyms=man

The context describes finding "the smallest common bit of genetic material" and refers to this material as "Such a piece of DNA".

This refers to a small, defined segment or portion of a larger natural object (DNA/chromosome).

Let's compare the relevant senses:

*   Sense 1 (a separate part of a whole): Fits generally, but is broad.
*   Sense 3 (a portion of a natural object): This is highly specific and accurate. DNA is a natural object (biological material), and the "piece" is a portion of it. Synonyms include 'part'.
*   Sense 5 (an instance of some kind): Synonyms include 'bit'. This is also very close, as DNA segment is a 'bit' of genetic material.
*   Sense 11 (a period of indeterminate length): Irrelevant.
*   Sense 12 (a share of something): Usually implies division among people or resources, not a segment of a molecule.

Comparing Sense 3 and Sense 5:
Sense 3: "a portion of a natural object" (e.g., piece of granite, piece of river). DNA fits this description perfectly.
Sense 5: "an instance of some kind" (synonyms: bit). The context explicitly mentions looking for the "smallest common bit of genetic material."

While Sense 5 uses the synonym 'bit', Sense 3 captures the physical nature of the object (DNA segment) as a 'portion of a natural object' more precisely than the abstract concept of 'instance'. Since DNA is a physical, natural structure, Sense 3 is the most precise fit for a segment of DNA.

Let's re-examine the phrasing: "Such a piece of DNA". This is a physical segment.

Sense 3: "a portion of a natural object" -> DNA is a natural object. This is the best fit.

I will select sense 3.

Analysis:
The sentence discusses a piece of DNA found by researchers. The researchers are trying to identify a gene. The statement is: "Such a piece of DNA would probably constitute a gene."

This statement is a prediction or a high probability assessment based on the scientific evidence they have gathered (it's a small, common bit of genetic material lost in all tumor cells).

Let's evaluate the senses:

Sense 1: "with considerable certainty; without much doubt" (synonyms: likely, in all likelihood).
If the researchers found a piece of DNA that fits the criteria for a gene (small, common, critical to the tumor), stating that it "would probably constitute a gene" means they are highly confident that this is what it is. This fits the meaning of "likely" or "with considerable certainty."

Sense 2: "easy to believe on the basis of available evidence" (synonyms: credibly, believably, plausibly).
While the finding is plausible, the context suggests a strong scientific conclusion based on the evidence ("Such a piece of DNA would... constitute a gene"). Sense 1 captures the degree of certainty inherent in a scientific hypothesis being strongly supported by data, which is closer to "likely" than merely "plausible."

Conclusion: Sense 1, meaning "likely" or "with considerable certainty," is the best fit for the context of scientific deduction and high probability.

I need to return the result in the specified JSON format, using the index of the chosen sense.
Sense 1 corresponds to index 1.

Analysis:
The sentence is: "Such a piece of DNA would probably constitute a gene."
The relationship is between "a piece of DNA" (the part) and "a gene" (the whole/entity).
The meaning here is that the piece of DNA *is* or *forms* the gene.

Let's evaluate the senses:
1. sense_key=constitute%2:42:00: Definition is "form or compose". Synonyms include "make up, comprise, be". This fits well. A piece of DNA makes up a gene.
2. sense_key=constitute%2:41:00: Definition is "create and charge with a task or function". This is about appointing people/roles, which is irrelevant here. (e.g., constitute a judge).
3. sense_key=constitute%2:42:03: Definition is "to compose or represent". Synonyms include "form, make". This also fits well. The piece of DNA forms the gene.
4. sense_key=constitute%2:36:00: Definition is "set up or lay the groundwork for". This implies establishment or foundation, which is too strong and doesn't fit the physical composition relationship.

Comparing Sense 1 and Sense 3:
Sense 1: "form or compose" (synonyms: make up, comprise, be).
Sense 3: "to compose or represent" (synonyms: form, make).

Both are very close. However, the context "Such a piece of DNA would probably constitute a gene" strongly suggests that the piece *is* the gene, or *is part of* the definition of the gene.
Sense 1's inclusion of "comprise" and "be" aligns perfectly with the idea of composition or identity (A comprises B, or A is B).
Sense 3 is also good, but Sense 1's definition ("form or compose") and synonyms ("make up, comprise") are slightly more precise for describing how a physical part (DNA piece) makes up a biological entity (gene).

Let's re-examine the provided indices.
Sense 1: 42:00 (form or compose)
Sense 3: 42:03 (to compose or represent)

Since both are highly relevant, I must choose the *single best* indexed sense. In biological/scientific contexts, when a part defines a whole, "comprise" (Sense 1) is often the most accurate term.

I will select Sense 1.

Context:
"It was the confirming evidence we all needed that gene losses were critical to the development of a common tumor, "says Ray White at Howard Hughes Medical Institute in Salt Lake City. But Dr. Vogelstein had yet to nail the identity of the gene that, if damaged, flipped a colon cell into full-blown malignancy. They focused on chromosome 17.

Target word: "found" (in the sentence: "When they found it last winter...")

Analysis of the context surrounding "found":
The researchers were "looking for the smallest common bit of genetic material lost in all tumor cells." This material is described as a piece of DNA, which would constitute a gene. The sentence states: "When they found it last winter, Dr. Vogelstein was dubious that the search was over."

The action of "finding" here refers to successfully locating or identifying the specific piece of genetic material (the gene/DNA segment) they were searching for.

Let's evaluate the candidate senses:

1. sense_key=find%2:40:02:: | definition=come upon, as if by accident; meet with | (Accidental encounter) - Unlikely, this was a targeted search.
2. sense_key=find%2:39:02:: | definition=discover or determine the existence, presence, or fact of | (Detect/Observe/Discover) - Plausible. They discovered the existence/presence of the gene segment.
3. sense_key=find%2:40:00:: | definition=come upon after searching; find the location of something that was missed or lost | (Regain/Locate after searching) - Very strong fit. They were actively searching ("looking for") the gene, and they "found it."
4. sense_key=find%2:32:00:: | definition=establish after a calculation, investigation, experiment, survey, or study | (Determine/Ascertain) - Plausible, but sense 3 focuses more on the physical/locational success of the search, which fits the context of finding a specific piece of DNA.
5. sense_key=find%2:31:10:: | definition=come to believe on the basis of emotion, intuitions, or indefinite grounds | (Feel) - Incorrect.
6. sense_key=find%2:39:01:: | definition=perceive or be contemporaneous with | (Witness/See) - Incorrect.
7. sense_key=find%2:40:01:: | definition=get something or somebody for a specific purpose | (Obtain/Line up) - Less precise than locating/discovering.
8. sense_key=find%2:36:00:: | definition=make a discovery, make a new finding | (Discover) - Plausible, but sense 3 is more specific to the process of locating something sought after.
9. sense_key=find%2:31:09:: | definition=make a discovery | (Discover) - Similar to 8.
10. sense_key=find%2:40:03:: | definition=obtain through effort or management | (Obtain) - Too broad.
11. sense_key=find%2:32:01:: | definition=decide on and make a declaration about | (Rule) - Incorrect.
12. sense_key=find%2:30:00:: | definition=receive a specified treatment (abstract) | (Receive/Incur) - Incorrect.
13. sense_key=find%2:39:05:: | definition=perceive oneself to be in a certain condition or place | (Find oneself) - Incorrect.
14. sense_key=find%2:40:15:: | definition=get or find back; recover the use of | (Recover/Regain) - Incorrect (not about recovering something lost, but locating something sought).
15. sense_key=find%2:38:10:: | definition=succeed in reaching; arrive at | (Arrive at) - Incorrect (not about reaching a physical target).
16. sense_key=find%2:30:13:: | definition=accept and make use of one's personality, abilities, and situation | (Find oneself) - Incorrect.

Comparing 2, 3, and 8/9:
Sense 2 (discover existence/presence): They discovered the gene.
Sense 3 (come upon after searching; find location): They found the location/identity of the gene they were searching for.
Sense 8/9 (make a discovery): They made a discovery.

Since the context explicitly details a search process ("looking for the smallest common bit of genetic material") and the successful outcome is the identification/location of that specific piece of DNA ("When they found it"), Sense 3, which emphasizes finding something *after searching* and locating it, is the most precise fit.

Sense 3: definition=come upon after searching; find the location of something that was missed or lost | synonyms=regain | examples=Did you find your glasses?; I cannot find my gloves!

This perfectly matches the scientific context of locating a specific genetic marker.

Evaluation:
The phrase "last winter" clearly refers to the winter immediately preceding the current time of narration.

Sense 1: "immediately past" (examples: last Thursday). This fits perfectly with "last winter."
Sense 2: "coming after all others in time or space or degree or being the only one remaining" (examples: the last time I saw Paris). While "last winter" is a specific time, Sense 1 is more precise for the temporal meaning of "last" when referring to a specific past period (like a month, year, or day).
Sense 3, 5, 6, 7, 8, 9 relate to finality, conclusion, degree, or rank, which are irrelevant here.
Sense 4 is about unlikelihood, also irrelevant.

Sense 1 is the best fit for "last winter."

3. sense_key=dubious%5:00:00:unconvinced:00 | definition=not convinced | examples=they admitted the force of my argument but remained dubious

Analysis of the context:
"Dr. Vogelstein was dubious that the search was over."
The structure "was dubious that [clause]" indicates a state of mind regarding the truth or certainty of the following clause. He had doubts about the conclusion (that the search was over).

Analysis of the candidates:
1. **uncertain/doubtful**: "fraught with uncertainty or doubt." This fits the idea of having doubts about the conclusion.
2. **questionable/suspicious**: "open to doubt or suspicion." This usually describes a *thing* (e.g., a dubious claim, a dubious record), not a state of being of a person regarding a fact. While related, the context describes his internal state of not being certain.
3. **unconvinced**: "not convinced." This perfectly captures the meaning of having doubts about a claim or conclusion.

Comparing 1 and 3:
Sense 1 (uncertain/doubtful) is very general.
Sense 3 (unconvinced) is highly specific to the context of evaluating a claim ("that the search was over").

The sentence structure "was dubious that..." strongly aligns with the meaning of being unconvinced or having reservations about the statement.

Therefore, sense 3 is the best fit.

Target word: "search" (in "the search was over").

Analysis of the context surrounding "search":
The preceding text describes researchers "experimentally crawled down the length of chromosome 17, looking for the smallest common bit of genetic material lost in all tumor cells." This is a scientific investigation aimed at finding a specific piece of genetic material (a gene).
The phrase "the search was over" refers to the completion of this investigative process.

Evaluation of candidate senses:

1. sense_key=search%1:04:00:: | definition=the activity of looking thoroughly in order to find something or someone | synonyms=hunt, hunting
    * This fits the idea of looking for a specific piece of DNA/gene. The researchers were actively looking for something.

2. sense_key=search%1:04:02:: | definition=an investigation seeking answers | examples=a thorough search of the ledgers revealed nothing; the outcome justified the search
    * This is a broader definition of an investigation. The entire process of finding the gene is an investigation seeking answers. This seems highly relevant, perhaps even more encompassing than sense 1, as the goal was not just to "find" but to identify the gene/material.

3. sense_key=search%1:22:00:: | definition=an operation that determines whether one or more of a set of items has a specified property | synonyms=lookup | examples=they wrote a program to do a table lookup
    * This refers to computational/database searching (lookup). Not applicable here.

4. sense_key=search%1:09:00:: | definition=the examination of alternative hypotheses | examples=his search for a move that would avoid checkmate was unsuccessful
    * This relates to theoretical/strategic testing (like in chess). While scientific research involves hypotheses, the context focuses on the physical act of finding the material ("crawled down... looking for the smallest common bit"). Sense 2 or 1 is better.

5. sense_key=search%1:04:01:: | definition=boarding and inspecting a ship on the high seas | examples=right of search
    * This is maritime/legal. Not applicable.

Comparison between Sense 1 and Sense 2:
Sense 1: "the activity of looking thoroughly in order to find something or someone" (Focus on the action/process of finding).
Sense 2: "an investigation seeking answers" (Focus on the overall goal/scope of the activity).

The context describes a complex scientific endeavor: "experimentally crawled down the length of chromosome 17, looking for the smallest common bit of genetic material lost in all tumor cells." This entire endeavor is fundamentally an *investigation seeking answers* (Sense 2). While it involves "looking thoroughly" (Sense 1), Sense 2 captures the high-level nature of the scientific project described (identifying the gene/cause of malignancy).

Given the scientific context (gene identification, tumor development), "an investigation seeking answers" (Sense 2) is the most precise and encompassing description of the activity that Dr. Vogelstein is referring to when he says "the search was over."

Therefore, Sense 2 is the best fit.

The target lemma is "doubt".
The context is: "When they found it last winter, Dr. Vogelstein was dubious that the search was over. His <t>doubts</t> stemmed from the fact that several years earlier a Princeton University researcher, Arnold Levine, had found in experiments with mice that a gene called p53 could transform normal cells into cancerous ones.

2. sense_key=doubt%1:07:00:: | definition=uncertainty about the truth or factuality or existence of something | synonyms=dubiousness, doubtfulness, question | examples=the dubiousness of his claim; there is no question about the validity of the enterprise

Analysis of the context:
Dr. Vogelstein found a specific deletion (a gene) in tumor cells. He was "dubious that the search was over." His "doubts stemmed from the fact that several years earlier a Princeton University researcher, Arnold Levine, had found... a gene called p53 could transform normal cells into cancerous ones. The deletion Dr. Vogelstein found was in exactly the same spot as p53."

The context indicates that Dr. Vogelstein's uncertainty (doubts) is related to the *implication* or *significance* of his finding—specifically, whether his finding was a new discovery or merely a confirmation of previous work (p53). He is questioning the completeness or novelty of his search.

Comparing the senses:
Sense 1: "the state of being unsure of something" (General uncertainty).
Sense 2: "uncertainty about the truth or factuality or existence of something" (Specific uncertainty regarding truth/fact/existence).

In this context, the doubts are not just general uncertainty, but specifically about the *fact* that his search was complete, given the prior knowledge of p53. He is questioning the *completeness* or *novelty* (a factual claim about the research process).

Sense 2, which focuses on uncertainty regarding "truth or factuality," seems slightly more precise for this scientific context where he is comparing his finding to established facts (Levine's p53 discovery).

However, Sense 1 ("the state of being unsure of something") is a very broad definition that encompasses the situation perfectly. The doubts are about the state of the search being "over."

Let's re-examine the relationship between the senses. Sense 2 is a specific type of uncertainty (about truth/fact). Sense 1 is the general state of uncertainty. Since the context is about questioning the *status* of the search (a factual claim), Sense 2 is a strong fit.

Let's check the synonyms and examples.
Sense 1 synonyms: uncertainty, incertitude, dubiety, doubtfulness, dubiousness.
Sense 2 synonyms: dubiousness, doubtfulness, question.

The context is: "His doubts stemmed from the fact that..." This implies his doubts were based on a factual conflict or comparison.

If I must choose the *single best* indexed sense, Sense 2 captures the intellectual nature of the doubt (questioning the established facts/completeness of the search) better than the general state described in Sense 1.

Therefore, Sense 2 is the best fit.

    *   The structure is "His doubts stemmed from the fact...". This indicates a causal relationship.

2.  **Analyze the candidate senses:**

    *   **Sense 1 (stem%2:42:00):** Definition: grow out of, have roots in, originate in. Example: "The increase in the national debt stems from the last war."
        *   *Match check:* "Doubts stemmed from the fact" perfectly matches the meaning of "originate in" or "have roots in." This is a strong candidate.

    *   **Sense 2 (stem%2:42:03):** Definition: cause to point inward. Example: "stem your skis."
        *   *Match check:* Irrelevant to doubts or causation.

    *   **Sense 3 (stem%2:30:00):** Definition: stop the flow of a liquid. Synonyms: stanch, staunch, halt. Example: "staunch the blood flow; stem the tide."
        *   *Match check:* This relates to stopping movement or flow. While "stemming doubts" could metaphorically mean stopping them, the context clearly uses "stemmed from" to mean *originating* from, not *stopping*.

    *   **Sense 4 (stem%2:30:01):** Definition: remove the stem from. Example: "for automatic natural language processing, the words must be stemmed."
        *   *Match check:* This is the linguistic/morphological sense (reducing words to their root form). It is completely unrelated to the context of scientific doubts and causation.

3.  **Compare the best candidates (Sense 1 vs. Sense 3):**
    *   Sense 1 (Originate in): "Doubts originated from the fact." (Perfect fit)
    *   Sense 3 (Stop flow): "Doubts stopped the fact." (Nonsensical)

4.  **Conclusion:** Sense 1 is the definitive best fit.

5.  **Format the output:** The instruction requires returning only a JSON object with the sense index. Sense 1 corresponds to index 1 in the provided list. (Wait, the instructions ask to return the index corresponding to the *chosen* sense, not the list order. Let's re-check the numbering provided in the prompt.)

    *   Candidate 1 -> Index 1
    *   Candidate 2 -> Index 2

Target word: fact

Candidate senses:
1. sense_key=fact%1:09:01:: | definition=a piece of information about circumstances that exist or events that have occurred | examples=first you must collect all the facts of the case
2. sense_key=fact%1:10:01:: | definition=a statement or assertion of verified information about something that is the case or has happened | examples=he supported his argument with an impressive array of facts

4. sense_key=fact%1:09:02:: | definition=a concept whose truth can be proved | examples=scientific hypotheses are not facts

Analysis of the context:
The sentence structure is: "His doubts stemmed from the fact that [subordinate clause describing a past event/finding]."
The subordinate clause is: "several years earlier a Princeton University researcher, Arnold Levine, had found in experiments with mice that a gene called p53 could transform normal cells into cancerous ones."

The "fact" here refers to the existence of this prior finding (the discovery by Levine). It is a piece of established knowledge or a known event.

Comparing with candidate senses:
1. sense_key=fact%1:09:01: "a piece of information about circumstances that exist or events that have occurred." This fits well. The finding is a piece of information about an event (the discovery).
2. sense_key=fact%1:10:01: "a statement or assertion of verified information..." This is also plausible, as the finding is verified information.
3. sense_key=fact%1:26:01: "an event known to have happened or something known to have existed." This is perhaps the closest fit. The finding (the transformation capability of p53) is a known event/existence established by the prior research. The examples ("your fears have no basis in fact") also suggest this sense relates to established reality.
4. sense_key=fact%1:09:02: "a concept whose truth can be proved." This is too abstract and philosophical for this context, which refers to a specific scientific finding.

Distinguishing between 1, 2, and 3:
Sense 1 focuses on "a piece of information."
Sense 2 focuses on "a statement or assertion of verified information."
Sense 3 focuses on "an event known to have happened or something known to have existed."

In the context "His doubts stemmed from the fact that [X happened]", 'fact' functions as a nominalization of a known reality or event. Sense 3, emphasizing "an event known to have happened or something known to have existed," captures the nature of the scientific finding (the existence of the p53 effect) most accurately. The finding itself is the known existence/event that causes the doubt.

Therefore, sense_key=fact%1:26:01 is the best fit.

Target word: several

Candidate senses:
1. sense_key=several%5:00:00:some:00 | definition=(used with count nouns) of an indefinite number more than 2 or 3 but not many | examples=several letters came in the mail; several people were injured in the accident

3. sense_key=several%5:00:00:different:00 | definition=distinct and individual | examples=three several times

Analysis:
The word "several" modifies "years" (a count noun).
The phrase is "several years earlier".
This usage indicates an indefinite quantity of time, more than two or three, but not a precise number.

Let's check the senses:
1. sense_key=several%5:00:00:some:00: Definition is "of an indefinite number more than 2 or 3 but not many (used with count nouns)". This perfectly matches "several years".
2. sense_key=several%5:00:00:individual:00: Definition is "considered individually". This is not the meaning here.
3. sense_key=several%5:00:00:different:00: Definition is "distinct and individual". While related to individuality, the primary meaning here is quantity, not distinction.

Conclusion: Sense 1 is the best fit.

Analysis:
The phrase is "several years earlier". This construction refers to a duration of time in the past.

1. sense_key=year%1:28:01: This sense defines a standard period of time (365/366 days). This fits the meaning of a duration of time ("several years earlier").
2. sense_key=year%1:28:02: This refers to a specific segment of a calendar year (e.g., academic year). This does not fit the context of a historical duration.
3. sense_key=year%1:28:00: This refers to astronomical orbital periods. This is irrelevant to the context.
4. sense_key=year%1:14:00: This refers to a cohort of students. This is irrelevant to the context.

Conclusion: Sense 1 is the best fit, as "several years earlier" refers to a span of time measured in standard calendar years.

Analysis:
The phrase is "several years earlier". This phrase indicates a point in time preceding the current narrative time (when Dr. Vogelstein found the gene).

Let's evaluate the senses:
1. **earlier in time; previously**: This perfectly matches the usage "several years earlier," indicating a time before the main event. Synonyms include "before."
2. **comparatives of `soon' or `early'**: This sense relates to comparison (e.g., "This happened earlier than that"). While "earlier" is a comparative form, the context uses it as an absolute temporal marker ("several years earlier"), not necessarily in a direct comparison structure, although it implies a temporal difference. However, sense 1 is a more direct fit for the meaning of "in the past."
3. **before now / in the first place**: This sense relates to initial state or origin (e.g., "in the first place"). This does not fit the temporal sequence described ("several years earlier").

Conclusion: Sense 1, defined as "earlier in time; previously," is the most accurate fit for "several years earlier."

Wait, let me re-examine the provided sense keys and definitions carefully, as sometimes the provided keys might be slightly misleading or overlapping.

Sense 1: definition=earlier in time; previously. (Matches "several years earlier")
Sense 2: definition=comparatives of `soon' or `early'. (Matches the grammatical form, but Sense 1 captures the semantic meaning better in this context.)
Sense 3: definition=before now. (Matches "in the first place," which is different from "several years ago.")

The usage "several years earlier" clearly means "at an earlier time in the past." This aligns perfectly with Sense 1.

I must choose the single best indexed sense.

Best fit: Sense 1.

Target word: "found" (in the phrase "had found in experiments with mice")

Analysis of the context surrounding the target word:
"...Arnold Levine, had found in experiments with mice that a gene called p53 could transform normal cells into cancerous ones."

The action described is a scientific finding/discovery made during experiments. Levine didn't just stumble upon it (chance), nor did he merely locate a lost item. He established a fact or a relationship (that p53 transforms cells) through investigation.

Reviewing the candidate senses:

1. sense_key=find%2:40:02:: | definition=come upon, as if by accident; meet with | (Accidental encounter - unlikely for a scientific finding.)
2. sense_key=find%2:39:02:: | definition=discover or determine the existence, presence, or fact of | (Detecting a fact/existence - highly relevant.)
3. sense_key=find%2:40:00:: | definition=come upon after searching; find the location of something that was missed or lost | (Locating a lost item - irrelevant.)
4. sense_key=find%2:32:00:: | definition=establish after a calculation, investigation, experiment, survey, or study | (Establishing a fact through investigation/experiment - highly relevant.)
5. sense_key=find%2:31:10:: | definition=come to believe on the basis of emotion, intuitions, or indefinite grounds | (Believing/feeling - irrelevant.)
6. sense_key=find%2:39:01:: | definition=perceive or be contemporaneous with | (Seeing/witnessing - irrelevant.)
7. sense_key=find%2:40:01:: | definition=get something or somebody for a specific purpose | (Acquiring/obtaining - less precise than discovery.)
8. sense_key=find%2:36:00:: | definition=make a discovery, make a new finding | (Making a discovery - highly relevant.)
9. sense_key=find%2:31:09:: | definition=make a discovery | (Making a discovery - highly relevant.)
10. sense_key=find%2:40:03:: | definition=obtain through effort or management | (Obtaining resources/time - irrelevant.)
11. sense_key=find%2:32:01:: | definition=decide on and make a declaration about | (Ruling/judging - irrelevant.)
12. sense_key=find%2:30:00:: | definition=receive a specified treatment (abstract) | (Receiving treatment - irrelevant.)
13. sense_key=find%2:39:05:: | definition=perceive oneself to be in a certain condition or place | (Finding oneself - irrelevant.)
14. sense_key=find%2:40:15:: | definition=get or find back; recover the use of | (Recovering/retrieving - irrelevant.)
15. sense_key=find%2:38:10:: | definition=succeed in reaching; arrive at | (Reaching a target - irrelevant.)
16. sense_key=find%2:30:13:: | definition=accept and make use of one's personality, abilities, and situation | (Finding oneself - irrelevant.)

Comparing the best candidates (2, 4, 8, 9):

*   Sense 2 (discover or determine the existence, presence, or fact of): This fits well. Levine determined the fact that p53 transforms cells.
*   Sense 4 (establish after a calculation, investigation, experiment, survey, or study): This is extremely specific and perfectly matches the context ("in experiments with mice").
*   Sense 8 (make a discovery, make a new finding): This is a general term for scientific breakthrough.
*   Sense 9 (make a discovery): Similar to 8, but slightly more general.

Sense 4 is the most precise fit because it explicitly links the finding to the methodology used ("in experiments with mice"). The context is clearly about the result of a scientific investigation.

Therefore, sense_key=find%2:32:00 is the best choice.

reasoning_content:
1.  **Analyze the target word and context:**
    *   Target surface form: "experiments"
    *   Target lemma: "experiment"
    *   Context sentence: "His doubts stemmed from the fact that several years earlier a Princeton University researcher, Arnold Levine, had found in <t>experiments</t> with mice that a gene called p53 could transform normal cells into cancerous ones."
    *   The context describes scientific research (Dr. Vogelstein, Johns Hopkins researchers, gene probes, chromosome 17, tumor cells, gene p53). Arnold Levine "found in experiments with mice" that a gene could cause cancer.

2.  **Analyze the candidate senses:**
    *   **Sense 1 (experiment%1:04:00):** definition=the act of conducting a controlled test or investigation | synonyms=experimentation. This aligns perfectly with scientific research ("experiments with mice").
    *   **Sense 2 (experiment%1:09:00):** definition=the testing of an idea | synonyms=experimentation | examples=it was an experiment in living; not all experimentation is done in laboratories. This is broader, but still relates to testing.
    *   **Sense 3 (experiment%1:04:01):** definition=a venture at something new or different | examples=as an experiment he decided to grow a beard. This refers to a trial or attempt, often personal or non-scientific (like a fashion choice).

3.  **Determine the best fit:**
    *   The context is highly scientific and involves controlled biological testing ("experiments with mice," finding a gene that transforms cells).
    *   Sense 1 ("the act of conducting a controlled test or investigation") is the most precise fit for scientific research conducted on mice.
    *   Sense 3 is clearly incorrect (it's not about growing a beard or a personal venture).
    *   Sense 2 is plausible, but Sense 1 is more specific and accurate for the context of biological research.

4.  **Select the final sense:** Sense 1.

5.  **Format the output:** JSON object with the sense index. (Sense 1 corresponds to index 1 in the list provided).

Target lemma: mouse
Target surface form: mice
Context:
But Dr. Vogelstein had yet to nail the identity of the gene that, if damaged, flipped a colon cell into full-blown malignancy. They focused on chromosome 17. For months the Johns Hopkins researchers, using gene probes, experimentally crawled down the length of chromosome 17, looking for the smallest common bit of genetic material lost in all tumor cells. Such a piece of DNA would probably constitute a gene. When they found it last winter, Dr. Vogelstein was dubious that the search was over. His doubts stemmed from the fact that several years earlier a Princeton University researcher, Arnold Levine, had found in experiments with <t>mice</t> that a gene called p53 could transform normal cells into cancerous ones. The deletion Dr. Vogelstein found was in exactly the same spot as p53.

Candidate senses:
1. sense_key=mouse%1:05:00:: | definition=any of numerous small rodents typically resembling diminutive rats having pointed snouts and small ears on elongated bodies with slender usually hairless tails
2. sense_key=mouse%1:26:00:: | definition=a swollen bruise caused by a blow to the eye | synonyms=shiner, black eye
3. sense_key=mouse%1:18:00:: | definition=person who is quiet or timid
4. sense_key=mouse%1:06:00:: | definition=a hand-operated electronic device that controls the coordinates of a cursor on your computer screen as you move it around on a pad; on the bottom of the device is a ball that rolls on the surface of the pad | synonyms=computer mouse | examples=a mouse takes much more room than a trackball

The user wants me to perform Word Sense Disambiguation (WSD) on the word "mice" (plural of "mouse") based on the provided context.

Context: "His doubts stemmed from the fact that several years earlier a Princeton University researcher, Arnold Levine, had found in experiments with <t>mice</t> that a gene called p53 could transform normal cells into cancerous ones. The deletion Dr. Vogelstein found was in exactly the same spot as p53."

Target word: mice (plural of mouse)

Candidate senses:
1. sense_key=mouse%1:05:00:: | definition=any of numerous small rodents typically resembling diminutive rats having pointed snouts and small ears on elongated bodies with slender usually hairless tails (Rodent)
2. sense_key=mouse%1:26:00:: | definition=a swollen bruise caused by a blow to the eye (Bruise)
3. sense_key=mouse%1:18:00:: | definition=person who is quiet or timid (Timid person)
4. sense_key=mouse%1:06:00:: | definition=a hand-operated electronic device that controls the coordinates of a cursor on your computer screen as you move it around on a pad; on the bottom of the device is a ball that rolls on the surface of the pad (Computer device)

Analysis:
The context mentions "experiments with mice" related to a gene (p53) that transforms normal cells into cancerous ones. This is a biological/genetic research context.

1. Rodent: Mice are commonly used laboratory animals in genetic and cancer research. This fits perfectly.
2. Bruise: A bruise cannot be used in experiments to study gene transformation. (Incorrect)
3. Timid person: A person cannot be used in experiments with genes in this manner. (Incorrect)
4. Computer device: A computer mouse cannot be used in biological experiments to study p53 gene function. (Incorrect)

The best fit is sense 1, referring to the small rodents used in the experiment.

The instructions require returning only a JSON object with the sense index.
Sense 1 corresponds to the rodent definition.
