Target lemma: visible
Target surface form: visible
Context:
The story of tumor-suppressor genes goes back to the 1970s, when a pediatrician named Alfred G. Knudson Jr. proposed that retinoblastoma stemmed from two separate genetic defects. He theorized that in the eye cancer, an infant inherited a damaged copy of a gene from one parent and a normal copy from the other. The tumor, he suggested, developed when the second, normal copy also was damaged. But there was no way to prove Dr. Knudson's "two-hit "theory. Back then, scientists had no way of ferreting out specific genes, but under a microscope they could see the 23 pairs of chromosomes in the cells that contain the genes. Occasionally, gross chromosome damage was <t>visible</t>. Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease.

The context describes scientists observing chromosome damage under a microscope. The word "visible" here means the damage was "capable of being seen" - it could be perceived by sight through the microscope. This matches sense 1's definition of "capable of being seen; or open to easy view." Sense 3 about availability is clearly inapplicable, and while sense 2 (obvious to the eye) has some contextual plausibility, sense 1 is the primary, most direct meaning in this scientific observation context.

reasoning_content:
Let me analyze the context and the three candidate senses for the word "visible".

The sentence is: "Occasionally, gross chromosome damage was visible."

This is discussing that under a microscope, scientists could occasionally see gross (obvious, noticeable) chromosome damage. The word "visible" here means that the damage could be seen/perceived with the eye.

Let me examine each sense:

1. sense_key=visible%3:00:00:: | definition=capable of being seen; or open to easy view | synonyms=seeable | examples=a visible object; visible stars
   - This sense means something can be seen, is perceivable by sight. This fits the context well - the chromosome damage could be seen under the microscope.

2. sense_key=visible%5:00:00:overt:00 | definition=obvious to the eye | examples=a visible change of expression
   - This sense emphasizes that something is obvious/apparent to the eye. The context mentions "gross chromosome damage" which is also obvious, so this could fit.

3. sense_key=visible%5:00:00:available:00 | definition=present and easily available | examples=the cash on hand is adequate for current needs; emergency police were on hand in case of trouble
   - This sense is about something being available or present. The examples don't match the context well - they're about availability, not about being able to see something.

The context is specifically about scientists being able to SEE chromosome damage under a microscope. Sense 3 is clearly wrong because it's about availability, not visibility.

Between sense 1 and 2:
- Sense 1: "capable of being seen; or open to easy view" - basic meaning of visibility
- Sense 2: "obvious to the eye" - emphasizes the obviousness/conspicuousness

The word "gross" in "gross chromosome damage" suggests it was obvious/conspicuous.

The phrase emphasizes that when damage appeared, it was conspicuous enough to detect. Sense 1 captures the fundamental meaning—something perceivable by sight—which aligns with the scientific observation of chromosome damage under magnification. While sense 2 adds an emphasis on obviousness, sense 1 provides the core definition that best fits this context.

The context describes Dr. Knudson establishing a finding through scientific investigation and study of chromosomes in children with eye cancer. He investigated the chromosomal data and determined (established) that certain children had inherited a damaged chromosome. This directly matches sense 4: "establish after a calculation, investigation, experiment, survey, or study," which is exemplified by "The physicist who found the elusive particle won the Nobel Prize"—a parallel situation of discovering something through systematic scientific study.

reasoning_content:
Let me analyze the context to determine the correct sense of "found" in this passage.

The context is about Dr. Knudson studying eye cancer and chromosomes. The sentence reads: "Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease."

Let me examine what "found" means here:
- He investigated/studied the data
- Through this investigation, he determined/discovered that some children had inherited a damaged chromosome
- The result of his investigation/experiment was this finding

This is clearly about discovering or determining something through investigation/study. Let me look at the candidate senses:

1. "come upon, as if by accident" - No, this wasn't accidental
2. "discover or determine the existence, presence, or fact of" - This could work, but it's about detecting something
3. "come upon after searching" - This is searching for a lost item, not applicable
4. "establish after a calculation, investigation, experiment, survey, or study" - This fits perfectly! He established through his study that children inherited this damaged chromosome
5. "come to believe on the basis of emotion" - No, not about emotions
6. "perceive or be contemporaneous with" - Not about witness/seeing
7. "get something for a specific purpose" - No
8. "make a discovery, make a new finding" - This could work
9. "make a discovery" - This could work
10. "obtain through effort" - Not quite right
11. "decide on and make a declaration" - Not a ruling situation
12. "receive a specified treatment" - No
13. "perceive oneself to be in a condition" - No
14. "get or find back" - No
15. "succeed in reaching" - No
16. "find oneself" - No

The best match is sense 4: "establish after a calculation, investigation, experiment, survey, or study" with the example "The physicist who found the elusive particle won the Nobel Prize" - this directly parallels Dr. Knudson's discovery through scientific investigation.
Senses 8 and 9 both capture the idea of making a discovery, but sense 4 is more precise here because it specifically emphasizes the methodical investigation and study that led to the finding, rather than just the act of discovery itself.

The context describes children with eye cancer (retinoblastoma) in a medical/genetic research setting. The passage begins by mentioning "an infant inherited" the damaged gene, establishing that the discussion concerns young people. The word "children" here refers to young persons of either sex who developed the disease, making sense 1 ("a young person of either sex") the most appropriate choice. Sense 2, while possible grammatically, typically refers to offspring of any age including adults, which doesn't fit the medical context of young cancer patients. Senses 3 and 4 are clearly inappropriate.

reasoning_content:
Let me analyze the context to determine which sense of "children" is being used.

The context is about Dr. Knudson's research on eye cancer (retinoblastoma). The sentence states: "Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease."

The passage is discussing medical research on infants and young people who developed eye cancer. The "children" in this context refers to young human beings who inherited genetic material from their parents and developed the disease.

Let me evaluate each sense:

1. Sense 1: "a young person of either sex" - This would apply to young children, minors. The examples given are "she writes books for children; they're just kids" - these suggest young people.

2. Sense 2: "a human offspring (son or daughter) of any age" - This could mean offspring of any age, including adults. Examples: "they had three children; they were able to send their kids to college" - these can refer to adult offspring.

3. Sense 3: "an immature childish person" - This refers to behavioral immaturity, not age. The examples are "he remained a child in practical matters as long as he lived; stop being a baby!"

4. Sense 4: "a member of a clan or tribe" - This is a cultural/genealogical meaning, as in "the children of Israel."

In the medical context, the passage mentions "an infant inherited" at the beginning, suggesting young children. The research is specifically about children with eye cancer. This is clearly about young people (sense 1) rather than offspring of any age (sense 2), behavioral immaturity (sense 3), or tribal membership (sense 4).

Sense 1 is the best fit because the context is about young people with a specific disease.

The context clearly refers to eye cancer as a disease affecting the biological organ of sight. The passage discusses how infants inherit damaged genes that lead to tumors in this organ, and mentions visible chromosome damage. This is unambiguously referring to the eye as the anatomical organ of vision, not as a metaphorical sense of perception, attention, or any other meaning.

reasoning_content:
Let me analyze the context to determine which sense of "eye" is being used.

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

The context is clearly discussing medical/biological terminology related to cancer. "Eye cancer" is referring to a cancer of the eye organ - specifically the context mentions "in the eye cancer, an infant inherited a damaged copy of a gene" which is about retinoblastoma, a cancer of the retina (part of the eye organ).

Let me evaluate each sense:

1. sense_key=eye%1:08:00:: | definition=the organ of sight | synonyms=oculus, optic
   - This is the anatomical organ of sight
   - This fits perfectly with "eye cancer" which is a cancer of this organ

2. sense_key=eye%1:09:00:: | definition=good discernment (either visually or as if visually)
   - This is about having good judgment or skill in perception
   - Does not fit the medical context

3. sense_key=eye%1:09:01:: | definition=attention to what is seen
   - This is about visual attention
   - Does not fit the medical context

4. sense_key=eye%1:15:00:: | definition=an area that is approximately central within some larger region
   - This is about the center of something
   - Does not fit the medical context

5. sense_key=eye%1:06:00:: | definition=a small hole or loop (as in a needle)
   - This is about a physical hole or opening
   - Does not fit the medical context

The answer is clearly sense 1 - the organ of sight. The text is discussing eye cancer, which is a disease of the eye organ.

Looking at the context, the passage is discussing a medical/scientific topic about eye cancer - specifically about inherited genes, tumors, and chromosome damage. This is clearly referring to cancer as a disease.

Let me examine the candidate senses:

1. sense_key=cancer%1:26:00:: - "any malignant growth or tumor caused by abnormal and uncontrolled cell division" - This is the medical definition of cancer as a disease.

2. sense_key=cancer%1:18:00:: - A person born while the sun is in Cancer (astrology)

5. sense_key=cancer%1:05:00:: - Type genus of the family Cancridae (biological genus, likely referring to crabs)

The context clearly indicates this is about cancer as a medical condition - a malignant tumor. The text discusses:
- "the eye cancer"
- "an infant inherited a damaged copy of a gene"
- "the tumor"
- "chromosome damage"
- "children with the eye cancer"

This is absolutely referring to sense 1: cancer as a malignant growth/tumor caused by abnormal cell division. This is the only sense that makes sense in this medical/scientific context.

The sense index for sense 1 would be 1.

Let me analyze the context to determine the correct sense of "inherited" in this passage.

The context is about genetics and eye cancer. The passage discusses:
- An infant inherited a damaged copy of a gene from one parent
- Children with eye cancer inherited a damaged copy of chromosome No. 13 from a parent

This is clearly about genetic transmission - receiving traits or genetic material from parents through biological inheritance.

Let me examine the three candidate senses:

1. sense_key=inherit%2:40:00:: - "obtain from someone after their death" (examples: inherited a castle from grandparents)
   - This is about inheriting property/material goods after death
   - NOT the correct sense

2. sense_key=inherit%2:40:02:: - "receive from a predecessor" (examples: inherited problems from previous chair)
   - This is about inheriting responsibilities or conditions from someone in a predecessor role
   - NOT the correct sense

3. sense_key=inherit%2:40:01:: - "receive by genetic transmission" (examples: inherited good eyesight from mother)
   - This is specifically about genetic/biological inheritance
   - This MATCHES the context perfectly - the passage is about inheriting genetic material (damaged genes/chromosomes) from parents

The answer is clearly sense 3 - "receive by genetic transmission" since the entire context is about genetic inheritance in the medical/scientific context of eye cancer transmission through genes.

The context describes a chromosome with a physical defect—specifically, missing genetic material that is visible under a microscope. The word "damaged" refers to the chromosome being physically harmed or structurally compromised, which matches the first sense ("harmed or injured or spoiled"). The second sense relates to reputational damage, which is irrelevant to this medical/genetic discussion.

reasoning_content:
Let me analyze the context to determine the correct sense of "damaged" in this passage.

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

The context is about:
- Eye cancer in infants
- Inherited genes and chromosomes
- A theory about how tumors develop when genes are damaged
- Physical observation of chromosome damage under a microscope

The two candidate senses are:
1. "harmed or injured or spoiled" - examples include "damaged goods" and "badly damaged buildings"
2. "being unjustly brought into disrepute" - as in "discredited politician" or "damaged reputation"

In this medical/genetic context, "damaged" refers to a chromosome that has a physical defect - specifically, a bit of chromosome 13 is missing. This is clearly a case of the chromosome being physically harmed or spoiled, not a case of reputation being damaged or discredited.

The word "damaged" in the context refers to the biological/physical damage to the chromosome structure. This corresponds to sense 1: "harmed or injured or spoiled."

Sense 2 is about reputational damage (discredited, damaged reputation), which is clearly not what's meant here.

The answer should be: sense index 1

The target word "copy" in this genetic context refers to an instance or version of a gene or chromosome that is similar or identical to another instance of the same genetic material. The passage describes how an infant inherited one copy of a gene from each parent, and later how children inherited copies of chromosomes. This matches sense 2, which defines copy as "a thing made to be similar or identical to another thing," perfectly capturing the biological usage where organisms carry multiple copies of genetic elements.

reasoning_content:
Let me analyze the context to understand which sense of "copy" is being used.

In the context, we have:
"He theorized that in the eye cancer, an infant inherited a damaged copy of a gene from one parent and a normal copy from the other."

And later:
"Dr. Knudson found that some children with the eye cancer had inherited a damaged <t>copy</t> of chromosome No. 13 from a parent who had had the disease."

The word "copy" is being used here in the biological/genetic sense to mean an instance or version of a genetic material (a gene or chromosome). The infant inherited one copy of a gene from each parent.

Let me evaluate each sense:

1. sense_key=copy%1:10:00:: - "a reproduction of a written record (e.g. of a legal or school record)" - This is about written records/transcripts. Not applicable.

2. sense_key=copy%1:06:00:: - "a thing made to be similar or identical to another thing" with examples like "she made a copy of the designer dress; the clone was a copy of its ancestor" - This is about making something similar/identical to something else. In the genetic context, a "copy" of a gene or chromosome is indeed something similar/identical to another instance of that genetic material. This seems like the best fit.

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

4. sense_key=copy%1:10:02:: - "material suitable for a journalistic account" - This is about material for news articles. Not applicable.

Sense 2 is clearly the best choice. It describes a "thing made to be similar or identical to another thing," which is exactly what a genetic copy is - an instance that is similar/identical to the original.
The answer is sense_key=copy%1:06:00:: (index 2), as this definition captures how genetic material exists in multiple instances that are essentially identical to one another.

reasoning_content:
Let me analyze the context to determine which sense of "parent" is being used.

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

Context analysis:
- We're talking about a genetic disease (eye cancer)
- A child inherited a damaged chromosome from a "parent"
- The parent also had the disease
- This is about biological inheritance

Now let me look at the two candidate senses:

1. sense_key=parent%1:18:00:: - "a father or mother; one who begets or one who gives birth to or nurtures and raises a child; a relative who plays the role of guardian"
   - This is the human/family sense of parent
   - Definition focuses on biological parenthood and familial role

2. sense_key=parent%1:03:00:: - "an organism (plant or animal) from which younger ones are obtained"
   - This is a more general biological sense
   - Could apply to any organism, not just humans

In the context, we're clearly talking about a human parent who had eye cancer and passed on a damaged chromosome to their child. The passage is discussing human inheritance and a specific genetic disease in humans.

The first sense (parent%1:18:00::) is specifically about "a father or mother" and someone who "begets or gives birth to a child" - this perfectly fits the human context of the sentence where someone inherited a chromosome from a parent.

The second sense is more general and could apply to plants or animals, which is not what we're talking about here.

Therefore, sense 1 is the best fit.

The use of "actually" in this context means "in actual fact" or "really." Dr. Knudson could truly observe the visible chromosome damage under a microscope, as opposed to merely theorizing or assuming it. This aligns with sense 1's definition and the synonym "really," which captures the meaning that he could genuinely see the missing piece of chromosome 13 as a factual matter.

reasoning_content:
Let me analyze the context in which "actually" is used.

The sentence is: "Under a microscope he could <t>actually</t> see that a bit of chromosome 13 was missing."

The context is about Dr. Knudson's scientific observations. He could "actually" see the chromosome damage under a microscope - meaning he could really, in fact, see it visually.

Let me look at each candidate sense:

1. sense_key=actually%4:02:01:: | definition=in actual fact | synonyms=really | examples=to be nominally but not actually independent; no one actually saw the shark
   - This means "in reality" or "really" - indicating actual fact rather than appearance or assumption.

2. sense_key=actually%4:02:00:: | definition=used to imply that one would expect the fact to be the opposite of that stated; surprisingly | synonyms=in reality | examples=you may actually be doing the right thing by walking out; she actually spoke Latin
   - This implies surprise or contradiction to expectations.

3. sense_key=actually%4:02:03:: | definition=at the present moment | examples=the transmission screen shows the picture that is actually on the air
   - This is about something happening right now.

4. sense_key=actually%4:02:02:: | definition=as a sentence modifier to add slight emphasis | examples=actually, we all help clear up after a meal; actually, I haven't seen the film
   - This is used as an emphasizing particle in sentences.

In the given sentence, "he could actually see" means he could really/truly see (versus just theorizing or assuming). This is sense 1 - "in actual fact" with synonym "really". This fits the example "no one actually saw the shark" - meaning they really did or didn't see it, in fact.

The answer is sense 1.

Looking at the context, the sentence is:

"Under a microscope he could actually <t>see</t> that a bit of chromosome 13 was missing."

The key phrase is "Under a microscope he could actually see that a bit of chromosome 13 was missing."

The doctor is looking through a microscope at chromosome samples and is able to perceive visually that a portion of chromosome 13 is missing. This is about visual perception/sight.

Looking at the candidate senses:

1. "perceive by sight or have the power to perceive by sight" - This is the most direct sense of "see" as in visual perception. The examples are "You have to be a good observer to see all the details; Can you see the bird in that tree?" This matches the context perfectly - he's using a microscope to see (visually perceive) the missing chromosome piece.

2. "perceive (an idea or situation) mentally" - This is about understanding, not visual perception.

3. "perceive or be contemporaneous with" - This is more about witnessing/observing events as they happen.

4. "imagine; conceive of; see in one's mind" - This is about mental visualization, not actual visual perception.

5. "deem to be" - This is about considering/regarding something.

6. "get to know or become aware of, usually accidentally" - This is about learning/awareness.

7. "see or watch" - This is about watching/observing, similar to sense 1 but with a focus on watching.

20. "observe, check out, and look over carefully or inspect" - This could work as it involves examining carefully.

The most straightforward interpretation is sense 1: "perceive by sight or have the power to perceive by sight" - the doctor is using a microscope to visually perceive that a portion of chromosome 13 is missing. This is basic visual perception.

The phrase "a bit of chromosome 13 was missing" refers to a small piece or portion of the chromosome that is no longer visible under the microscope. Sense 1 ("a small piece or quantity of something") best captures this meaning in the medical/scientific context, where "a bit of" is used to describe an indefinite small portion of a larger structure. The example "a bit of paper" parallels the use here of describing a small piece of a physical object.

reasoning_content:
The context is about a microscope view of chromosome 13, where "a bit of chromosome 13 was missing." This is describing a small piece or portion of the chromosome that is no longer there.

Let me consider the candidate senses:

1. "a small piece or quantity of something" - This fits well. A "bit" of chromosome refers to a small piece.

2. "a small fragment of something broken off from the whole" - This also fits. A missing piece of chromosome could be described as a fragment.

3. "an indefinitely short time" - Doesn't fit. This is about time, not about a physical piece.

4. "an instance of some kind" - Could fit but less precise than option 1.

5. "piece of metal held in horse's mouth" - Clearly doesn't fit.

6. "unit of measurement of information" - Doesn't fit.

7. "a small amount of solid food; a mouthful" - Doesn't fit.

8. "a small fragment" - Similar to option 2, this could fit.

9. "a short theatrical performance" - Doesn't fit.

10. "part of a key" - Doesn't fit.

11. "cutting part of a drill" - Doesn't fit.

The most relevant senses are 1, 2, and 8.

Looking at the context more carefully: "a bit of chromosome 13 was missing" - this is referring to a small piece of the chromosome that is no longer visible, that has been lost.

Sense 1: "a small piece or quantity of something" with synonyms "spot" and examples "a spot of tea; a bit of paper"
Sense 2: "a small fragment of something broken off from the whole" with synonyms "chip, flake, fleck, scrap" and examples "a bit of rock caught him in the eye"
Sense 8: "a small fragment" with synonyms "snatch" and examples "overheard snatches of their conversation"
Sense 1 seems most fitting here—it's the broadest definition covering any small portion or piece, which applies directly to the missing chromosomal segment without requiring the additional implication of something being broken off.

In this context, Dr. Knudson is making an inference or supposition about the missing chromosome piece based on the visual evidence he observed. He is taking something to be true—that the missing piece contained critical genes—without having complete verification or proof at that point in time. This matches sense 1: "take to be the case or to be true; accept without verification or proof" with synonyms "presume, take for granted."

reasoning_content:
Let me analyze the context to understand which sense of "assumed" is being used.

From the context: "He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer."

This is Dr. Knudson making a conclusion or supposition based on the evidence he observed (a missing piece of chromosome 13). He's taking something to be true without having full verification or proof yet - he can see the missing chromosome piece, but doesn't yet know which specific genes disappeared.

Let me review the candidate senses:

1. "take to be the case or to be true; accept without verification or proof" - This matches perfectly. He is assuming/presuming that the missing piece contains a gene without having absolute proof yet.

2. "take on titles, offices, duties, responsibilities" - This doesn't fit. He's not taking on a role or duty.

3. "take on a certain form, attribute, or aspect" - This doesn't fit. He's not acquiring or taking on a physical form or attribute.

4. "take on as one's own the expenses or debts of another person" - This doesn't fit. Nothing about financial responsibility.

5. "occupy or take on" (as in assume a position) - This doesn't fit. He's not occupying a physical position.

6. "seize and take control without authority" - This doesn't fit. No forceful seizure involved.

7. "make a pretence of" - This doesn't fit. He's not pretending or simulating.

8. "take up someone's soul into heaven" - This is religious and doesn't fit.

9. "put clothing on one's body" - This doesn't fit. No clothing involved.

The best match is sense 1: "take to be the case or to be true; accept without verification or proof" with synonyms "presume, take for granted". The examples given "I assume his train was late" is very similar in structure to the context - making an assumption based on incomplete information.

The word "piece" refers to a portion of a natural object (the chromosome). In the context, Dr. Knudson observed that "a bit of chromosome 13 was missing" and "assumed the missing piece contained a gene or genes." This is describing a portion of a naturally occurring biological structure, which aligns precisely with sense 3's definition of "a portion of a natural object" and its example "he needed a piece of granite."

reasoning_content:
Let me analyze the context for the target word "piece":

"Under a microscope he could actually see that a bit of chromosome 13 was missing. He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer."

The context is about a missing part of chromosome 13. The sentence structure and meaning indicate that "piece" refers to a portion or part of something larger - the chromosome.

Let me examine the candidate senses:

1. sense_key=piece%1:06:00:: - "a separate part of a whole" - This seems relevant as a missing piece of chromosome is a part of a whole
2. sense_key=piece%1:06:05:: - "an item that is an instance of some type" - Not as relevant
3. sense_key=piece%1:17:00:: - "a portion of a natural object" - This could fit well. It's about a piece of chromosome (a natural object), and the synonym is "part"
4. sense_key=piece%1:10:01:: - "a musical work" - Not relevant
5. sense_key=piece%1:11:00:: - "an instance of some kind" - Not specific enough
6. sense_key=piece%1:10:02:: - "an artistic or literary composition" - Not relevant
7. sense_key=piece%1:06:03:: - "a portable gun" - Not relevant
8. sense_key=piece%1:13:00:: - "a serving that has been cut from a larger portion" - Not quite right context
9. sense_key=piece%1:07:00:: - "a distance" - Not relevant
10. sense_key=piece%1:06:04:: - "a work of art" - Not relevant
11. sense_key=piece%1:28:00:: - "a period of indeterminate length" - Not relevant
12. sense_key=piece%1:21:00:: - "a share of something" - Not the best fit
13. sense_key=piece%1:06:02:: - "game equipment" - Not relevant

The most fitting sense is #3: "a portion of a natural object." Since a chromosome is a biological entity and the missing piece represents a segment of it, this definition aligns with the passage's meaning. The examples given—analyzing a river into parts or needing a piece of granite—parallel the scenario of identifying a missing chromosomal segment.

While sense 1 ("a separate part of a whole") could apply, sense 3 is more precise because it specifically addresses portions extracted from natural objects rather than just any component of something larger.

The target word "contained" is used in the context of the missing chromosome piece having genes as components/parts. The scientist assumes the missing piece of chromosome 13 included genes as its constituent parts. This matches sense 1 ("include or contain; have as a component"), which is synonymous with "comprise" and fits the biological context where genes are understood as components of chromosomes.

reasoning_content:
Let me analyze the sentence to determine the correct sense of "contained" in this context:

"He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer."

The context is about a piece of chromosome 13 that is missing. The scientist is hypothesizing that this missing piece (which he's discussing) contained a gene or genes.

Let me examine each sense:

1. "include or contain; have as a component" - This means the piece includes genes as components. This fits well - the missing piece would have genes as its components.

2. "contain or hold; have within" - Similar meaning to sense 1, but emphasizes physical holding/bearing. This could work too.

3. "lessen the intensity of; temper; hold in restraint" - This is about control/moderation. This doesn't fit.

4. "be divisible by" - Mathematical sense. Doesn't fit.

5. "be capable of holding or containing" - This is about capacity/capability. The sentence is talking about what the piece actually contained, not its capability.

6. "hold back, as of a danger or an enemy" - This is about restraining or checking. Doesn't fit.

Between senses 1 and 2:
- Sense 1: "include or contain; have as a component" - emphasizes that genes are components
- Sense 2: "contain or hold; have within" - emphasizes physical holding

In this genetic context, the missing piece of chromosome is understood to have genes as components/parts. The scientist assumes the genes are part of/components of the chromosome piece. Sense 1 seems more appropriate because it specifically mentions "have as a component."

Actually, both 1 and 2 seem similar. Let me look at the examples:
- Sense 1: "The record contains many old songs from the 1930's" - this is about having things as components
- Sense 2: "The jar carries wine" - this is more about physical holding
In a genetic context, we're talking about structural composition rather than physical containment. The chromosome piece has genes as integral parts of its structure, which aligns with sense 1's emphasis on components rather than sense 2's focus on holding.

The context describes how the absence of specific genes (due to missing chromosome material) contributes to cancer development. The phrase "whose loss had a critical role in setting off the cancer" emphasizes the **disadvantage** or **negative consequence** resulting from the missing genetic material. This aligns with sense 4, which defines loss as "the disadvantage that results from losing something," with the example "his loss of credibility led to his resignation" showing a similar pattern where the absence of something causes an important effect.

reasoning_content:
Let me analyze the context to determine the best sense for "loss" in this passage.

The context is about Dr. Knudson observing that a bit of chromosome 13 was missing in children with eye cancer. He assumed that the missing piece contained a gene or genes whose "loss" had a critical role in setting off the cancer.

In this context, "loss" refers to the disappearance or absence of genetic material (genes) that would normally be present. The missing genes are the thing that is "lost."

Let me examine each sense:

1. "something that is lost" - This could fit, but it's very general.
2. "gradual decline in amount or activity" - This doesn't fit well; there's no gradual aspect mentioned.
3. "the act of losing someone or something" - This could fit, referring to the act of losing the genes.
4. "the disadvantage that results from losing something" - This fits well; the loss of genes is what leads to cancer.
5. "the experience of losing a loved one" - This doesn't fit; it's not about a loved one.
6. "the amount by which the cost of a business exceeds its revenue" - This doesn't fit; it's not about business.
7. "military personnel lost by death or capture" - This doesn't fit; it's not about military.
8. "euphemistic expressions for death" - This doesn't fit; it's not a euphemism.

Looking more carefully:
- Sense 1 (something that is lost) - "the car was a total loss" - this focuses on the thing itself that is lost
- Sense 3 (the act of losing someone or something) - "everyone expected him to win so his loss was a shock" - this focuses on the event/process of losing
- Sense 4 (the disadvantage that results from losing something) - "his loss of credibility led to his resignation" - this focuses on the consequence or negative effect

The passage describes how the absence of genes produces a harmful outcome—cancer develops as a result. This consequence-focused meaning aligns best with sense 4, where the loss itself becomes the causal factor in the disease.

In this context, "critical role" refers to something that is absolutely necessary or essential. The passage explains that Dr. Knudson hypothesized that the missing genes on chromosome 13 had an essential role in causing cancer—without them, the cancer could develop. This matches sense 4: "urgently needed; absolutely necessary," which is synonymous with "vital" and exemplified by phrases like "critical element of the plan."

reasoning_content:
Let me analyze the context to determine which sense of "critical" is being used.

The sentence is: "He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer."

In this context, "critical" is describing the role that the missing genes have in initiating cancer. Let me consider each sense:

1. "marked by a tendency to find and call attention to errors and flaws" - This doesn't fit. It's about having a critical attitude, not about a role being critical.

2. "at or of a point at which a property or phenomenon suffers an abrupt change" - This could fit in a scientific context, but it's more about critical mass/critical temperature situations.

3. "characterized by careful evaluation and judgment" - This refers to criticism or careful analysis, doesn't fit here.

4. "urgently needed; absolutely necessary" - This could fit. The genes whose loss is critical could mean their presence is absolutely necessary.

5. "forming or having the nature of a turning point or crisis" - This could fit. The loss of these genes could be the turning point in cancer development.

6. "being in or verging on a state of crisis or emergency" - This is about a state of crisis, which doesn't match the usage here.

7. "of or involving or characteristic of critics or criticism" - Doesn't fit.

The key phrase is "critical role in setting off the cancer." This suggests something that is essential/necessary (sense 4) or a turning point/crucial element (sense 5).

Between senses 4 and 5:
- Sense 4: "urgently needed; absolutely necessary" with example "critical element of the plan"
- Sense 5: "forming or having the nature of a turning point or crisis" with example "critical point in the campaign"

The context is about genes whose loss has a "critical role in setting off the cancer." This is about something that is essential/necessary for cancer development. It's describing an essential element. Sense 4 seems like the best fit - it's about something being absolutely necessary.
Both senses 4 and 5 are plausible, but the phrase "critical role in setting off" emphasizes something vital and essential to the process rather than a turning point. Sense 4 captures this better—the genes are absolutely necessary for cancer development.

The answer is: {"sense_index": 4}

The word "role" in this context refers to the **function or purpose** that the missing genes have in the biological process of cancer development. The sentence states the genes "had a critical role in setting off the cancer," which describes their functional contribution to the disease mechanism. This matches sense 3 (what something is used for), which covers function and purpose more broadly than the other senses. The other senses refer to personal/social roles (senses 1 and 4) or theatrical performance (sense 2), which are not applicable in this scientific/genetic context.

reasoning_content:
Let me analyze the context to determine the best sense of "role" in this sentence:

"He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer."

The context is about genetics and the biological process of cancer development. The word "role" is describing the function or purpose that the missing genes have in causing (or setting off) the cancer.

Let me examine each sense:

1. sense 1 (role%1:04:00::): "the actions and activities assigned to or required or expected of a person or group" - This is about personal/group responsibilities, like a teacher's function or government's part. Not fitting here.

2. sense 2 (role%1:09:00::): "an actor's portrayal of someone in a play" - This is clearly about theatrical performance. Not fitting here.

3. sense 3 (role%1:07:00::): "what something is used for" - This is about function and purpose. The definition says "what something is used for" with synonyms: function, purpose, use. Examples include "the function of an auger is to bore holes" and "ballet is beautiful but what use is it?"

4. sense 4 (role%1:04:01::): "normal or customary activity of a person in a particular social setting" - This is also about personal activity in social contexts. Not fitting here.

In the context, the genes have a "critical role in setting off the cancer" - this is clearly about their function or purpose in the biological process. This is not about personal or social roles, nor about theatrical performance.

Between sense 1 and sense 3, sense 3 seems more appropriate because it's about the function/purpose of something (genes in this case), whereas sense 1 is about activities assigned to persons or groups.

Actually, looking more carefully:
- Sense 1: "the actions and activities assigned to or required or expected of a person or group" - This could work in a metaphorical sense for genes having an assigned function
- Sense 3: "what something is used for" - This is broader and includes non-personal entities

Since the passage discusses genes in a scientific context, sense 3 best captures their function in the biological process of cancer development. The answer is sense 3.

The context describes how a missing gene could have a role in initiating cancer development. The verb "setting off" here means to trigger or activate the disease process. This matches sense 1 ("put in motion or move to act") with its synonyms "trigger, actuate, activate, spark off" and examples like "trigger a reaction." The biological sense of causing cancer to begin is most naturally expressed through the "trigger" meaning.

reasoning_content:
Let me analyze the context for "setting off" in the sentence: "He assumed the missing piece contained a gene or genes whose loss had a critical role in <t>setting off</t> the cancer."

The context is about how a missing gene could have a role in causing or initiating cancer. The word "setting off" here means "causing to begin" or "initiating" or "triggering" the development of cancer.

Let me look at each candidate sense:

1. "put in motion or move to act" - synonyms: trip, actuate, trigger, activate, spark off, spark. This is about initiating action or motion. The examples "trigger a reaction; actuate the circuits" fit well with "setting off the cancer" meaning causing it to start.

2. "leave" - This doesn't fit the context at all.

3. "direct attention to, as if by means of contrast" - This doesn't fit.

4. "cause to burst with a violent release of energy" - This is about explosions, not relevant here.

5. "make up for" - This doesn't fit.

6. "set in motion or cause to begin" - This fits well. "The guide set the tour off to a good start" - similar to how the missing gene sets off the cancer.

7. "provoke or stir up" - synonyms: incite, instigate, stir up. This could work but is more about causing unrest/disturbance.

Between senses 1 and 6, both seem relevant. Sense 1 emphasizes "trigger, activate, spark" which are good synonyms. Sense 6 emphasizes "set in motion or cause to begin" which is also very fitting.

Looking more carefully:
- Sense 1: "put in motion or move to act" with "trigger" as a synonym
- Sense 6: "set in motion or cause to begin"

In the context of cancer, "setting off the cancer" means initiating its development.

Sense 1 appears most fitting since "trigger" is explicitly listed as a synonym and the parallel example "trigger a reaction" closely mirrors how a gene loss would trigger cancer development.

Occasionally, gross chromosome damage was visible. Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease. Under a microscope he could actually see that a bit of chromosome 13 was missing. He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the <t>cancer</t>. But he did not know which gene or genes had disappeared.

Let me analyze the context to determine which sense of "cancer" is being used.

The passage discusses:
- Dr. Knudson's "two-hit" theory about cancer
- Children with eye cancer
- Inherited damaged chromosome copies
- Gene mutations related to cancer development
- The missing chromosome piece being related to setting off cancer

This is clearly a medical/biological context about disease. The word "cancer" refers to a malignant tumor or disease caused by abnormal cell division.

Looking at the candidate senses:
1. "any malignant growth or tumor caused by abnormal and uncontrolled cell division" - This matches the medical context perfectly
2. A person born under Cancer zodiac sign - Not relevant
3. A zodiacal constellation - Not relevant
4. The zodiac sign - Not relevant
5. A genus of crabs - Not relevant

The answer is clearly sense 1, which is the medical definition of cancer as a malignant disease/tumor caused by abnormal cell division.
