Context:
In recent months, researchers have come to believe the two types of cancer genes work in concert: An oncogene may turn proliferating cells malignant only after the tumor-suppressor gene has been damaged. Like all genes, tumor-suppressor genes are inherited in two copies, one from each parent. Either copy can make the proteins needed to control cell growth, so for cancer to arise, both copies must be impaired. A person who is born with one defective copy of a suppressor gene, or in whom one copy is damaged early in life, is especially prone to cancer because he need only lose the other copy for a cancer to develop. Emerging genetic tests will be able to spot such cancer-susceptible individuals, ushering in what some scientists believe is a new age of predictive cancer diagnosis. Bill and Bonnie Quinlan are among the <t>first</t> beneficiaries of the new findings. The Dedham, Mass., couple knew even before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance of being at risk for retinoblastoma, an eye cancer that occurs about once every 20,000 births.

Target word: first

Candidate senses:
1. sense_key=first%3:00:00:: | definition=preceding all others in time or space or degree | examples=the first house on the right; the first day of spring (General ordinal/temporal)
2. sense_key=first%5:00:00:ordinal:00 | definition=indicating the beginning unit in a series | synonyms=1st (Specific ordinal)
3. sense_key=first%5:00:02:opening:00 | definition=serving to set in motion | synonyms=inaugural, initiative, initiatory, maiden | examples=the magazine's inaugural issue; the initiative phase in the negotiations (Initiating/Pioneering)
4. sense_key=first%5:00:01:opening:00 | definition=serving to begin | synonyms=beginning | examples=the beginning canto of the poem; the first verse (Starting point)
5. sense_key=first%5:00:00:best:00 | definition=ranking above all others | synonyms=foremost, world-class | examples=was first in her class; the foremost figure among marine artists (Superiority)
6. sense_key=first%3:00:03:: | definition=highest in pitch or chief among parts or voices or instruments or orchestra sections | examples=first soprano; the first violin section (Musical/Rank)

Analysis of the context:
"Bill and Bonnie Quinlan are among the first beneficiaries of the new findings."

"Beneficiaries" refers to people who receive benefits. "First beneficiaries" means they are among the initial group to receive these benefits, or they are among the earliest recipients.

Evaluating the senses:
1. sense_key=first%3:00:00:: (preceding all others in time or space or degree): This fits well. Being the "first" beneficiary implies preceding others in time.
2. sense_key=first%5:00:00:ordinal:00 (indicating the beginning unit in a series): This is also a strong fit, as beneficiaries are part of a series/group.
3. sense_key=first%5:00:02:opening:00 (serving to set in motion): This implies they *caused* the findings or the process, which is not the case. They *received* them. (Incorrect)
4. sense_key=first%5:00:01:opening:00 (serving to begin): Similar to 3, this relates to starting something, not being the first recipient. (Incorrect)
5. sense_key=first%5:00:00:best:00 (ranking above all others): While they might be considered the "best" beneficiaries, the context strongly suggests temporal priority (being among the initial group), not necessarily superior quality. (Less likely)
6. sense_key=first%3:00:03:: (highest in pitch or chief among parts): Irrelevant. (Incorrect)

Comparing 1 and 2:
Sense 1 (preceding all others in time or space or degree) is a broad definition covering temporal precedence.
Sense 2 (indicating the beginning unit in a series) is specific to ordinal numbering.

In the phrase "among the first beneficiaries," the meaning is clearly temporal/ordinal—they were among the initial group. Both 1 and 2 capture this. However, Sense 1's definition ("preceding all others in time or space or degree") is the most comprehensive and accurate description of being an early recipient. Sense 2 is very specific to numerical ordering (1st, 2nd, etc.), whereas "among the first" implies inclusion in the initial cohort.

Let's re-examine the provided sense keys and definitions.
Sense 1: "preceding all others in time or space or degree" -> Fits "early recipients."
Sense 2: "indicating the beginning unit in a series" -> Fits "initial members of a group."

Since the context is about being among the initial group to receive something (temporal/sequential), Sense 1 is the most robust fit for the concept of temporal precedence.

I will choose Sense 1.

1.  **Analyze the target word and context:**
    *   Target word: `beneficiaries` (plural of `beneficiary`).
    *   Context sentence: "Bill and Bonnie Quinlan are among the first <t>beneficiaries</t> of the new findings."
    *   Surrounding text discusses new genetic tests and predictive cancer diagnosis ("ushering in what some scientists believe is a new age of predictive cancer diagnosis").

2.  **Analyze the candidate senses:**

    *   **Sense 1:** `sense_key=beneficiary%1:18:00`
        *   Definition: "the recipient of funds or other benefits"
        *   Synonyms: "donee"
        *   *Application to context:* The "new findings" (predictive cancer diagnosis) are a benefit. Bill and Bonnie are the recipients of this benefit (the ability to know their risk). This fits well.

    *   **Sense 2:** `sense_key=beneficiary%1:10:00`
        *   Definition: "the semantic role of the intended recipient who benefits from the happening denoted by the verb in the clause"
        *   Synonyms: "benefactive role"
        *   *Application to context:* This is a grammatical/linguistic role (a semantic function), not a person receiving a benefit. The context refers to people (Bill and Bonnie). This sense is incorrect.

3.  **Compare and select the best sense:**
    *   Sense 1 refers to a person who receives a benefit (the new diagnostic knowledge). This perfectly matches the context where the "new findings" are the benefit.
    *   Sense 2 is a technical linguistic term and does not apply to the people mentioned.

4.  **Final decision:** Sense 1 is the best fit.

1.  **Analyze the context:** The sentence is: "Bill and Bonnie Quinlan are among the first beneficiaries of the <t>new</t> findings."
2.  **Determine the meaning of 'new' in this context:** 'New' modifies 'findings'. 'Findings' refers to scientific discoveries or results mentioned earlier in the text (about cancer genes and predictive diagnosis).

The Dedham, Mass., couple knew even before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance of being at risk for retinoblastoma, an eye cancer that occurs about once every 20,000 births."

3. sense_key=finding%1:17:00:: | definition=something that is found | examples=the findings in the gastrointestinal tract indicate that he died several hours after dinner; an area rich in archaeological findings

Analysis of the context:
The preceding text discusses "Emerging genetic tests" and "predictive cancer diagnosis."
The sentence containing the target word is: "Bill and Bonnie Quinlan are among the first beneficiaries of the new findings."
Since the context is about new genetic tests and predictive diagnosis, the "findings" must refer to the results or discoveries made by these tests/research.

Evaluation of senses:
1. sense_key=finding%1:04:00: "the act of determining the properties of something, usually by research or calculation." This definition focuses on the *act* (determination). While related, the context suggests the *results* of the determination.
2. sense_key=finding%1:04:01: "the decision of a court..." This is clearly incorrect as the context is medical/genetic research, not legal.
3. sense_key=finding%1:17:00: "something that is found." This refers to the results or discoveries themselves. In the context of genetic tests and diagnosis, the "new findings" are the results discovered by the tests (e.g., the discovery that they are at risk). This aligns perfectly with the context.

Conclusion: Sense 3, "something that is found," is the best fit, referring to the results or discoveries from the genetic tests.

5. sense_key=couple%1:17:00:: | definition=(physics) something joined by two equal and opposite forces that act along parallel lines

Analysis:
The context refers to "Bill and Bonnie Quinlan" and then says, "The Dedham, Mass., couple knew...". Bill and Bonnie are people, and the context discusses their family planning and genetic risk for their child. The word "couple" here refers to Bill and Bonnie as a unit.

Let's evaluate the senses:
1. sense_key=couple%1:14:00 (a pair who associate with one another): This fits. Bill and Bonnie are a pair who associate.
2. sense_key=couple%1:14:01 (a pair of people who live together): This also fits, as they are a couple (likely married or partners) living together, and the context implies a family unit.
3. sense_key=couple%1:23:01 (a small indefinite number): Incorrect. It refers to two specific people.
4. sense_key=couple%1:23:00 (two items of the same kind): Incorrect. It refers to people, not generic items.
5. sense_key=couple%1:17:00 (physics): Incorrect.

Distinguishing between Sense 1 and Sense 2:
Sense 1: "a pair who associate with one another" (General association/relationship).
Sense 2: "a pair of people who live together" (Specific residential/marital relationship).

In common usage, when referring to two people who are parents and discussing their family life (pregnancy, risk to their child), "a couple" usually implies a committed, often cohabiting or married, unit (Sense 2). However, Sense 1 is broader and perfectly accurate ("a pair who associate").

Let's look at the examples provided for Sense 1 and Sense 2.
Sense 1 examples: "the engaged couple; an inseparable twosome" (Engaged implies association).
Sense 2 examples: "a married couple from Chicago" (Married implies living together/committed relationship).

Since the context is about a family unit (Bill and Bonnie, pregnancy, child risk), Sense 2 ("a pair of people who live together") captures the typical social and familial implication of "a couple" in this setting more precisely than the general association in Sense 1. They are presented as a unit making decisions about their shared child.

However, if I must choose the *single best* indexed sense, and both 1 and 2 are very close, I should check if there is a subtle difference in how they are indexed. Often, Sense 2 (married/cohabiting pair) is the most common usage when referring to a family unit.

Let's re-read the context: "The Dedham, Mass., couple knew even before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance..." This strongly suggests a committed partnership.

I will select Sense 2 as it is the most specific and contextually appropriate definition for a pair of people discussing their shared child.

Sense 2: a pair of people who live together.

The user wants me to perform Word Sense Disambiguation for the word "knew" (past tense of "know") based on the provided context.

Context: "The Dedham, Mass., couple <t>knew</t> even before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance of being at risk for retinoblastoma, an eye cancer that occurs about once every 20,000 births."

The word "knew" is followed by the clause "that any child of theirs had a 50% chance of being at risk for retinoblastoma". This indicates that the couple possessed information or awareness about a specific fact (the 50% risk).

Let's examine the candidate senses:

1. **sense_key=know%2:31:01::** definition=be cognizant or aware of a fact or a specific piece of information; possess knowledge or information about. Synonyms=cognize, cognise.
   * *Fit:* The couple was aware of a specific fact (the 50% risk). This is a very strong match.

2. **sense_key=know%2:31:03::** definition=know how to do or perform something.
   * *Fit:* No. They didn't know *how* to do something.

3. **sense_key=know%2:31:02::** definition=be aware of the truth of something; have a belief or faith in something; regard as true beyond any doubt.
   * *Fit:* They were aware of the truth of the risk probability. This is also a strong match, perhaps slightly more focused on belief/certainty than just possessing information, but it overlaps heavily with sense 1.

4. **sense_key=know%2:31:00::** definition=be familiar or acquainted with a person or an object.
   * *Fit:* No. They weren't familiar with the risk in a social sense.

5. **sense_key=know%2:31:04::** definition=have firsthand knowledge of states, situations, emotions, or sensations.
   * *Fit:* No. This is about personal experience, not statistical risk knowledge.

6. **sense_key=know%2:31:06::** definition=accept (someone) to be what is claimed or accept his power and authority.
   * *Fit:* No.

7. **sense_key=know%2:31:15::** definition=have fixed in the mind.
   * *Fit:* This relates to memorization (e.g., knowing Latin), which is not the primary meaning here.

8. **sense_key=know%2:35:00::** definition=have sexual intercourse with.
   * *Fit:* No.

9. **sense_key=know%2:31:11::** definition=know the nature or character of.
   * *Fit:* No.

10. **sense_key=know%2:31:12::** definition=be able to distinguish, recognize as being different.
   * *Fit:* No.

11. **sense_key=know%2:31:14::** definition=perceive as familiar.
   * *Fit:* No.

Comparing Sense 1 and Sense 3:
Sense 1 (31:01): "be cognizant or aware of a fact or a specific piece of information; possess knowledge or information about."
Sense 3 (31:02): "be aware of the truth of something; have a belief or faith in something; regard as true beyond any doubt."

The context states they "knew... that any child of theirs had a 50% chance of being at risk." This is a factual piece of information they were made aware of. Sense 1, focusing on possessing knowledge/information about a fact, is the most direct and accurate description of this situation. While Sense 3 is close, Sense 1 captures the informational aspect perfectly.

I select Sense 1.

Target lemma: even
Target surface form: even
Context:
Like all genes, tumor-suppressor genes are inherited in two copies, one from each parent. Either copy can make the proteins needed to control cell growth, so for cancer to arise, both copies must be impaired. A person who is born with one defective copy of a suppressor gene, or in whom one copy is damaged early in life, is especially prone to cancer because he need only lose the other copy for a cancer to develop. Emerging genetic tests will be able to spot such cancer-susceptible individuals, ushering in what some scientists believe is a new age of predictive cancer diagnosis. Bill and Bonnie Quinlan are among the first beneficiaries of the new findings. The Dedham, Mass., couple knew <t>even</t> before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance of being at risk for retinoblastoma, an eye cancer that occurs about once every 20,000 births. Mr. Quinlan, 30 years old, knew he carried a damaged gene, having lost an eye to the rare tumor when he was only two months old -- after his mother had suffered the same fate when she was a baby.

The user wants me to perform Word Sense Disambiguation for the target word "even" in the given context.
The context sentence is: "The Dedham, Mass., couple knew <t>even</t> before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance of being at risk for retinoblastoma, an eye cancer that occurs about once every 20,000 births."

Target word: even
Contextual usage: "knew even before Bonnie became pregnant"

Let's analyze the candidate senses:

1. **sense_key=even%4:02:00:** used as an intensive especially to indicate something unexpected. (e.g., "even an idiot knows that"). This sense often emphasizes surprise or extremity.
2. **sense_key=even%4:02:03:** in spite of; notwithstanding. (e.g., "even when he is sick, he works"). This is concessive.
3. **sense_key=even%4:02:01:** to a greater degree or extent; used with comparisons. (e.g., "looked sick and felt even worse"). This is comparative.
4. **sense_key=even%4:02:04:** to the full extent. (e.g., "loyal even unto death").

In the sentence "knew even before Bonnie became pregnant," "even" is modifying the time phrase "before Bonnie became pregnant." It emphasizes that the knowledge existed *at that earlier point in time* (or earlier than expected/at least as early as possible).

Let's test the senses:

*   **Sense 1 (Intensive/Unexpected):** Does it mean the knowledge was surprising or unexpected? Yes, knowing the risk before conception might be considered a strong or unexpected piece of information, but the primary function here is temporal emphasis.
*   **Sense 2 (In spite of):** Does it mean "despite" the fact that Bonnie hadn't become pregnant? No.
*   **Sense 3 (To a greater degree/extent):** This sense is usually used with comparisons (e.g., "even more"). While "even" can function as an intensifier, the structure here ("knew even before X") is more about emphasizing the timing/degree of earliness rather than a comparative degree.
*   **Sense 4 (To the full extent):** This doesn't fit the temporal context.

Revisiting Sense 1: "used as an intensive especially to indicate something unexpected." When used temporally, "even" often functions as an intensifier meaning "so early that it is noteworthy" or "even at that point." For example, "He knew even then." This fits the function of emphasizing the earliness of the knowledge.

Let's look closely at the typical usage of "even" as an intensifier/emphasizer (Sense 1). It highlights a surprising or noteworthy fact. Knowing the risk *before* conception is a noteworthy fact regarding the timing.

If we consider the function of "even" here, it is functioning as an emphatic adverb, stressing the point in time. This aligns best with the function described in Sense 1, where it acts as an intensive to highlight a specific point or condition.

Comparing Sense 1 and Sense 3:
Sense 3 is explicitly comparative ("even worse").
Sense 1 is generally intensive/emphatic ("even an idiot").

In "knew even before...", "even" is intensifying the temporal boundary ("before Bonnie became pregnant"). This is a strong intensive usage, fitting Sense 1 better than the comparative structure of Sense 3.

Therefore, Sense 1 is the best fit.

Analysis:
The phrase is "knew even before Bonnie became pregnant in 1987".
This structure indicates a temporal relationship. The knowledge existed at a time that preceded the event of Bonnie becoming pregnant in 1987.

Sense 1: "earlier in time; previously". This matches the temporal relationship in the context.
Sense 2: "at or in the front". This refers to spatial location and does not fit the context.

Conclusion: Sense 1 is the correct sense.

    *   **Sense 1 (become%2:30:00):** definition=enter or assume a certain state or condition | synonyms=go, get | examples=He became annoyed...
        *   *Fit check:* Becoming pregnant is entering a specific state/condition. This is a strong candidate.

        *   *Fit check:* While pregnancy is a change, this sense often implies a transformation from one physical state to another (like water to ice, or friend to enemy). Sense 1 seems more precise for the state of pregnancy.

    *   **Sense 3 (become%2:42:00):** definition=come into existence | examples=What becomes has duration.
        *   *Fit check:* Pregnancy is a process leading to existence, but the verb *became* here refers to the *onset* of the state of pregnancy, not the creation of the concept or object itself. This sense is too abstract/ontological for this specific usage.

    *   **Sense 4 (become%2:42:03):** definition=enhance the appearance of | synonyms=suit | examples=Mourning becomes Electra; This behavior doesn't suit you!
        *   *Fit check:* Completely irrelevant.

3.  **Compare the best candidates (Sense 1 vs. Sense 2):**
    *   The context is "Bonnie became pregnant."
    *   Sense 1: "enter or assume a certain state or condition." (State = pregnant). This is a perfect match.
    *   Sense 2: "undergo a change or development." (Change = pregnancy). This is also plausible, but Sense 1 captures the specific meaning of transitioning into the *state* of being pregnant more accurately than the general concept of "undergoing a change."

4.  **Conclusion:** Sense 1 is the most precise fit for "became pregnant."

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

Analysis:
The context states that Bonnie became "pregnant" in 1987, and immediately follows this with information about the risk of cancer in "any child of theirs." This strongly relates to the state of carrying a developing offspring.

Sense 1: "carrying developing offspring within the body or being about to produce new life." This perfectly matches the context of a couple discussing the risk to their future child after one partner becomes pregnant.

Sense 2: "rich in significance or implication." This is metaphorical and does not fit the biological context.
Sense 3: "filled with or attended with." This is also metaphorical (e.g., "a pregnant pause") and does not fit the context of reproduction.

Conclusion: Sense 1 is the correct sense.

Analysis:
The phrase "any child of theirs" clearly refers to the offspring of the couple (the parents mentioned).

Sense 1: "a young person of either sex". This is too broad. While offspring are young people, the context specifically relates to them being the *offspring* of the couple, and the definition doesn't emphasize the parent-child relationship as strongly as Sense 2.
Sense 2: "a human offspring (son or daughter) of any age". This perfectly matches the usage "child of theirs" (meaning their offspring).
Sense 3: "an immature childish person". This refers to immaturity or youthfulness in a behavioral sense, which is incorrect here.
Sense 4: "a member of a clan or tribe". This is incorrect.

Sense 2 is the best fit.

Target word: chance

Analysis of the context:
The phrase is "had a 50% chance of being at risk". The presence of "50%" strongly suggests a quantitative measure of likelihood or probability.

Analysis of candidate senses:
1. sense_key=chance%1:26:00:: | definition=a possibility due to a favorable combination of circumstances | synonyms=opportunity | (Focuses on opportunity/favorable circumstances) - Less likely given the percentage.
2. sense_key=chance%1:19:00:: | definition=an unknown and unpredictable phenomenon that causes an event to result one way rather than another | synonyms=luck, fortune, hazard | (Focuses on unpredictable events/luck) - Less likely given the percentage.
3. sense_key=chance%1:04:00:: | definition=a risk involving danger | examples=you take a chance when you let her drive | (Focuses on risk/danger) - While being at risk is dangerous, the structure "50% chance" points to a measure, not just the concept of risk itself.
4. sense_key=chance%1:07:00:: | definition=a measure of how likely it is that some event will occur; a number expressing the ratio of favorable cases to the whole number of cases possible | synonyms=probability | (Focuses on likelihood/ratio/probability) - This perfectly matches the structure "50% chance".

Target lemma: eye
Target surface form: eye
Context:
Like all genes, tumor-suppressor genes are inherited in two copies, one from each parent. Either copy can make the proteins needed to control cell growth, so for cancer to arise, both copies must be impaired. A person who is born with one defective copy of a suppressor gene, or in whom one copy is damaged early in life, is especially prone to cancer because he need only lose the other copy for a cancer to develop. Emerging genetic tests will be able to spot such cancer-susceptible individuals, ushering in what some scientists believe is a new age of predictive cancer diagnosis. Bill and Bonnie Quinlan are among the first beneficiaries of the new findings. The Dedham, Mass., couple knew even before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance of being at risk for retinoblastoma, an <t>eye</t> cancer that occurs about once every 20,000 births. Mr. Quinlan, 30 years old, knew he carried a damaged gene, having lost an eye to the rare tumor when he was only two months old -- after his mother had suffered the same fate when she was a baby.

Candidate senses:
1. sense_key=eye%1:08:00:: | definition=the organ of sight | synonyms=oculus, optic
2. sense_key=eye%1:09:00:: | definition=good discernment (either visually or as if visually) | examples=she has an eye for fresh talent; he has an artist's eye

reasoning_content:
1.  **Analyze the context:** The sentence is: "The Dedham, Mass., couple knew even before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance of being at risk for retinoblastoma, an <t>eye</t> cancer that occurs about once every 20,000 births."
2.  **Identify the target word and its role:** The target word is "eye," used as an adjective modifying "cancer" (retinoblastoma, an *eye* cancer).
3.  **Analyze the surrounding information:** The context discusses genetic predisposition, cancer (retinoblastoma), and the physical consequences of the disease (Mr. Quinlan "lost an eye to the rare tumor").
4.  **Evaluate the candidate senses:**
    *   **sense_key=eye%1:08:00:: | definition=the organ of sight | synonyms=oculus, optic:** This refers to the physical organ. Retinoblastoma is a cancer of the eye organ. This fits perfectly.
    *   **sense_key=eye%1:09:00:: | definition=good discernment...:** This is figurative (e.g., "an eye for talent"). Does not fit a physical cancer.
    *   **sense_key=eye%1:09:01:: | definition=attention to what is seen:** This is figurative (e.g., "catch her eye"). Does not fit a physical cancer.
    *   **sense_key=eye%1:15:00:: | definition=an area that is approximately central...:** This refers to a location or center. Does not fit a physical cancer.
    *   **sense_key=eye%1:06:00:: | definition=a small hole or loop...:** This refers to a physical opening (e.g., needle eye). Does not fit a physical cancer.
5.  **Select the best sense:** Sense 1 (the organ of sight) is the only sense that makes sense in the context of retinoblastoma, a known ocular cancer, and the subsequent mention of losing an eye.
6.  **Format the output:** The instruction requires returning only a JSON object with the sense index. Sense 1 corresponds to index 1. (Wait, the prompt asks for the index number, not the key. Let's re-check the numbering. The candidates are listed 1 through 5.)
    *   Candidate 1 -> sense_key=eye%1:08:00
    *   Candidate 2 -> sense_key=eye%1:09:00
    *   Candidate 3 -> sense_key=eye%1:09:01
    *   Candidate 4 -> sense_key=eye%1:15:00
    *   Candidate 5 -> sense_key=eye%1:06:00
7.  **Final choice:** Sense 1.

2. sense_key=occur%2:31:00:: | definition=come to one's mind; suggest itself | synonyms=come | examples=It occurred to me that we should hire another secretary; A great idea then came to her
3. sense_key=occur%2:42:03:: | definition=to be found to exist | examples=sexism occurs in many workplaces; precious stones occur in a large area in Brazil

Analysis of the context:
The sentence discusses retinoblastoma, an eye cancer. The phrase is "an eye cancer that occurs about once every 20,000 births."
This describes the frequency or incidence of the cancer.

Evaluation of senses:
1. sense_key=occur%2:30:00:: | definition=come to pass | synonyms=happen, hap, go on, pass off, pass, fall out. This sense relates to events happening or coming into existence. "Occurs about once every 20,000 births" fits perfectly with the meaning of "happens" or "comes to pass" (i.e., the cancer happens/is found in that frequency).
2. sense_key=occur%2:31:00:: | definition=come to one's mind; suggest itself. This is clearly incorrect. The cancer is not suggesting itself to the couple.
3. sense_key=occur%2:42:03:: | definition=to be found to exist. This sense relates to existence (e.g., stones existing in an area). While cancer exists, the context specifies a rate ("about once every 20,000 births"), making the sense of "happening" or "coming to pass" (Sense 1) a much better fit for frequency/incidence.

Conclusion: Sense 1, meaning "come to pass" or "happen," is the best fit for describing the incidence rate of the cancer.

The required output format is a JSON object with the sense index. Sense 1 corresponds to index 1.

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

Context: "The Dedham, Mass., couple knew even before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance of being at risk for retinoblastoma, an eye cancer that occurs <t>about</t> once every 20,000 births."

Target word: "about"

The phrase is "occurs about once every 20,000 births."
Here, "about" modifies the frequency ("once every 20,000 births"). It indicates that the frequency is approximately that amount, but not necessarily exactly.

Let's examine the candidate senses:

1. sense_key=about%4:02:00:: | definition=(of quantities) imprecise but fairly close to correct | synonyms=approximately, close to, just about, some, roughly, more or less | examples=lasted approximately an hour; in just about a minute
    * This sense relates to approximation of quantity/time/frequency. This fits perfectly with "about once every 20,000 births."

2. sense_key=about%4:02:06:: | definition=all around or on all sides | synonyms=around | examples=dirty clothes lying around (or about); let's look about for help
    * This is spatial/locational. Incorrect.

3. sense_key=about%4:02:01:: | definition=in the area or vicinity | synonyms=around | examples=a few spectators standing about; hanging around
    * This is spatial/locational. Incorrect.

4. sense_key=about%4:02:04:: | definition=used of movement to or among many different places or in no particular direction | synonyms=around | examples=wandering about with no place to go; people were rushing about
    * This is movement. Incorrect.

5. sense_key=about%4:02:02:: | definition=in or to a reversed position or direction | synonyms=around | examples=about face; suddenly she turned around
    * This is directional/positional. Incorrect.

6. sense_key=about%4:02:03:: | definition=in rotation or succession | examples=turn about is fair play
    * This is related to rotation/sequence. Incorrect.

7. sense_key=about%4:02:05:: | definition=(of actions or states) slightly short of or not quite accomplished; all but | synonyms=almost, most, nearly, near, nigh, virtually | examples=the job is (just) about done; the baby was almost asleep when the alarm sounded
    * This means "nearly" or "almost." While related to approximation, sense 1 specifically covers approximation of quantities/frequency ("approximately," "roughly"), which is the function here. Sense 7 is more about completion or state (e.g., "about finished").

Conclusion: Sense 1, defined as "(of quantities) imprecise but fairly close to correct" and synonymous with "approximately" or "roughly," is the best fit for "about once every 20,000 births."

Analysis of the context:
"...an eye cancer that occurs about once every 20,000 births."
Here, "once" modifies the frequency of occurrence ("every 20,000 births"). It means it happens one time within that specified interval.

Evaluation of senses:
1. sense_key=once%4:02:00 (on one occasion): This fits perfectly. "Once every 20,000 births" means it happens on one occasion within that group of births.
2. sense_key=once%4:02:02 (as soon as): This is temporal sequencing (e.g., "Once I finish, I will call"). This does not fit the frequency context.
3. sense_key=once%4:02:01 (at a previous time): This refers to a past state or period (e.g., "Once upon a time"). This does not fit the frequency context.

Conclusion: Sense 1 is the best fit.

Target word: births

Candidate senses:
1. sense_key=birth%1:28:00:: | definition=the time when something begins (especially life) | examples=they divorced after the birth of the child; his election signaled the birth of a new age
2. sense_key=birth%1:11:00:: | definition=the event of being born | synonyms=nativity, nascency, nascence | examples=they celebrated the birth of their first child

5. sense_key=birth%1:18:00:: | definition=a baby born; an offspring | examples=the overall rate of incidence of Down's syndrome is one in every 800 births

Analysis of the context:
The phrase is "an eye cancer that occurs about once every 20,000 births."
This phrase is used to describe the frequency or incidence rate of a disease (retinoblastoma).
When discussing incidence rates (e.g., "one in every X births"), "births" refers to the total number of live births or the event of a child being born, used as a unit of measurement for population statistics.

Evaluation of senses:
1. sense_key=birth%1:28:00 (time when something begins): Not applicable. It's a count/unit, not a temporal marker of beginning.
2. sense_key=birth%1:11:00 (the event of being born): This refers to the event itself. In statistical contexts like "one in every X births," this sense is often used to denote the occurrence of a birth event.
3. sense_key=birth%1:22:00 (the process of giving birth): This refers to the action (parturition). Not applicable here.
4. sense_key=birth%1:24:00 (kinship relation): Not applicable.
5. sense_key=birth%1:18:00 (a baby born; an offspring): This sense defines the *result* (the baby). However, the example provided for this sense is "the overall rate of incidence of Down's syndrome is one in every 800 births." This example uses "births" in the exact statistical context as the target sentence. Furthermore, the definition "a baby born; an offspring" is slightly misleading when used as a countable unit in a rate (it refers to the event/unit, not the individual baby itself, though they are related).

Comparing 2 and 5:
Sense 2: "the event of being born." This is a general definition for the occurrence.
Sense 5: "a baby born; an offspring." The provided example ("one in every 800 births") strongly aligns with the usage in the target sentence. In statistical epidemiology, "births" is used as a count of the event/unit, which aligns well with the concept of an offspring/baby being born.

Given the strong alignment of the example provided for sense 5 ("one in every 800 births") with the target context ("one every 20,000 births"), sense 5 is the most precise fit for the statistical usage of the word.

Therefore, sense_key=birth%1:18:00 is the best choice.

Either copy can make the proteins needed to control cell growth, so for cancer to arise, both copies must be impaired. A person who is born with one defective copy of a suppressor gene, or in whom one copy is damaged early in life, is especially prone to cancer because he need only lose the other copy for a cancer to develop. Emerging genetic tests will be able to spot such cancer-susceptible individuals, ushering in what some scientists believe is a new age of predictive cancer diagnosis. Bill and Bonnie Quinlan are among the first beneficiaries of the new findings. The Dedham, Mass., couple knew even before Bonnie became pregnant in 1987 that any child of theirs had a 50% chance of being at risk for retinoblastoma, an eye cancer that occurs about once every 20,000 births. Mr. Quinlan, 30 years old, <t>knew</t> he carried a damaged gene, having lost an eye to the rare tumor when he was only two months old -- after his mother had suffered the same fate when she was a baby. Because of the isolation of the retinoblastoma tumor-suppressor gene, it became possible last January to find out what threat the Quinlan baby faced.

Context sentence: "Mr. Quinlan, 30 years old, <t>knew</t> he carried a damaged gene, having lost an eye to the rare tumor when he was only two months old -- after his mother had suffered the same fate when she was a baby."

Target word: knew (meaning 'knew' in this context).

Analysis of the context:
Mr. Quinlan is stated to have "knew he carried a damaged gene." This means he possessed the information or awareness that he had this gene. The subsequent clause explains *why* he knew: "having lost an eye to the rare tumor when he was only two months old." This loss of an eye due to the tumor is the evidence that led him to the knowledge.

Evaluation of candidate senses:

1. sense_key=know%2:31:01:: definition=be cognizant or aware of a fact or a specific piece of information; possess knowledge or information about. (Synonyms: cognize, cognise).
   * Fits perfectly. He was aware of the fact (carrying a damaged gene).

2. sense_key=know%2:31:03:: definition=know how to do or perform something.
   * Does not fit. He didn't know *how* to carry a gene.

3. sense_key=know%2:31:02:: definition=be aware of the truth of something; have a belief or faith in something; regard as true beyond any doubt.
   * This is close, as knowing a fact implies it is true. However, sense 31:01 (cognizance/awareness of a fact) is a more direct fit for possessing specific information ("he carried a damaged gene"). Sense 31:02 often implies a deeper conviction or belief in a general truth, whereas here it is a specific, verifiable piece of information.

4. sense_key=know%2:31:00:: definition=be familiar or acquainted with a person or an object.
   * Does not fit.

5. sense_key=know%2:31:04:: definition=have firsthand knowledge of states, situations, emotions, or sensations. (Synonyms: experience, live).
   * While the knowledge is derived from experience (losing an eye), the core meaning here is the *possession of the fact* ("he carried a damaged gene"), not the feeling or state itself. Sense 31:01 is better for factual knowledge.

6. sense_key=know%2:31:06:: definition=accept (someone) to be what is claimed or accept his power and authority.
   * Does not fit.

7. sense_key=know%2:31:15:: definition=have fixed in the mind.
   * This relates to memorization or retention, not the acquisition of factual awareness in this context.

8. sense_key=know%2:35:00:: definition=have sexual intercourse with.
   * Does not fit.

9. sense_key=know%2:31:11:: definition=know the nature or character of.
   * Does not fit.

10. sense_key=know%2:31:12:: definition=be able to distinguish, recognize as being different.
    * Does not fit.

11. sense_key=know%2:31:14:: definition=perceive as familiar.
    * Does not fit.

Conclusion: Sense 31:01 ("be cognizant or aware of a fact or a specific piece of information") is the most accurate description of Mr. Quinlan's state of mind.

The corresponding sense index is 1.
