Target lemma: copy
Target surface form: copy
Context:
He theorized that in the eye cancer, an infant inherited a damaged copy of a gene from one parent and a normal copy from the other. The tumor, he suggested, developed when the second, normal copy also was damaged. But there was no way to prove Dr. Knudson's "two-hit "theory. Back then, scientists had no way of ferreting out specific genes, but under a microscope they could see the 23 pairs of chromosomes in the cells that contain the genes. Occasionally, gross chromosome damage was visible. Dr. Knudson 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. Under a microscope he could actually see that a bit of chromosome 13 was missing.

reasoning_content:
The target word is "copy" in the context: "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 talks about a damaged copy of a gene or chromosome.
Let's look at the candidate senses:
1. a reproduction of a written record (e.g. of a legal or school record)
2. a thing made to be similar or identical to another thing (e.g., she made a copy of the designer dress; the clone was a copy of its ancestor)
3. matter to be printed; exclusive of graphical materials
4. material suitable for a journalistic account

In the context, "copy" refers to a thing made to be similar or identical to another thing (a copy of a gene, a copy of a chromosome). A chromosome is a thing, and a copy of it is a thing made to be similar or identical to another thing.
Sense 2 fits best.
Let's double check.
"an infant inherited a damaged copy of a gene from one parent and a normal copy from the other."
"copy" here means a duplicate or a version of a thing (gene/chromosome).
Sense 2: "a thing made to be similar or identical to another thing"
This perfectly matches the biological context of a gene or chromosome copy.
Sense 1 is for written records.
Sense 3 is for printed matter.
Sense 4 is for journalistic material.
Therefore, sense 2 is the correct choice.
The output format must be exactly {"sense_index": 2}.
I will output {"sense_index": 2}.

The target word is "parent".
Context: "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 talks about a child inheriting a damaged copy of a chromosome from a parent.
Sense 1: 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.
Sense 2: an organism (plant or animal) from which younger ones are obtained.

In this context, "parent" refers to a human father or mother from whom a child inherits genes.
Sense 1 is the best fit.
Let's double check. "a father or mother; one who begets or one who gives birth to or nurtures and raises a child"
Yes, "parent" in the context of human genetics and inheritance of a disease from a parent to a child.
Sense 1 is the correct sense.

The target word is "bit" in the context: "Under a microscope he could actually see that a bit of chromosome 13 was missing."
The context refers to a small piece or fragment of a chromosome.
Let's evaluate the candidate senses:
1. sense_key=bit%1:23:01:: | definition=a small piece or quantity of something | synonyms=spot | examples=a spot of tea; a bit of paper
2. sense_key=bit%1:17:00:: | definition=a small fragment of something broken off from the whole | synonyms=chip, flake, fleck, scrap | examples=a bit of rock caught him in the eye

Wait, "a bit of chromosome 13 was missing" - is it a small piece or quantity of something (1) or a small fragment of something broken off from the whole (2)?
Let's check the examples. "a bit of paper" (1) vs "a bit of rock caught him in the eye" (2).
A chromosome is a physical structure, and a piece of it is missing. "a small piece or quantity of something" (1) seems very fitting for "a bit of chromosome 13".
Wait, sense 1 is "a small piece or quantity of something".
Sense 2 is "a small fragment of something broken off from the whole".
Is a missing piece of a chromosome a fragment broken off? Yes, but "a bit of chromosome 13" is more like "a bit of paper" (a small piece).
Let's look at similar examples in WordNet. "a bit of paper" is sense 1. "a bit of rock" is sense 2.
Is "a bit of chromosome" more like "a bit of paper" or "a bit of rock"?
Actually, "a small piece or quantity of something" (1) is often used for "a bit of [mass noun or singular noun]".
Let's consider "a bit of chromosome 13". Chromosome is a countable noun, but here it's treated as a mass or a piece of it.
Wait, let's look at sense 1: "a small piece or quantity of something".
Sense 2: "a small fragment of something broken off from the whole".
In the text: "a bit of chromosome 13 was missing."
Could it be sense 1? Yes.
Let's check if there is a more specific sense.
What about sense 1 vs sense 2?
"a bit of chromosome 13" -> a small piece of chromosome 13.
I will choose sense 1.
Wait, let's re-read the context: "a bit of chromosome 13 was missing."
Is it a fragment broken off? "missing piece" is used in the next sentence: "He assumed the missing piece contained a gene..."
"missing piece" aligns with "small piece or quantity of something" (sense 1) or "small fragment" (sense 2).
But "a bit of paper" is sense 1. "a bit of chromosome" is a small piece.
Let's choose sense 1.
Wait, let's look at the synonyms for sense 1: spot.
Synonyms for sense 2: chip, flake, fleck, scrap.
A piece of a chromosome is not really a chip, flake, fleck, or scrap. It's just a small piece. So sense 1 is better.
Let's double check.
"a bit of chromosome 13" -> a small piece or quantity of something.
I'll go with 1.
Wait, could it be 1? Yes.
Let's review the options.
1. a small piece or quantity of something
2. a small fragment of something broken off from the whole
I will select 1.
Let's consider if "bit" here means "small piece". Yes.
I'll output 1.

The target word is "piece" in the context: "Under a microscope he could actually see that a bit of chromosome 13 was missing. He assumed the missing <t>piece</t> contained a gene or genes whose loss had a critical role in setting off the cancer."
The context refers to a physical part of a chromosome, a natural object.
Let's look at the candidate senses:
1. a separate part of a whole (evidence)
2. an item that is an instance of some type (equipment, china)
3. a portion of a natural object (part, river, granite)
4. a musical work
5. an instance of some kind (bit, piece of work)
6. an artistic or literary composition
7. a portable gun
8. a serving that has been cut from a larger portion (pie, bread)
9. a distance
10. a work of art
11. a period of indeterminate length
12. a share of something (revenue)
13. game equipment

Sense 3: "a portion of a natural object" with synonyms "part" and examples "they analyzed the river into three parts; he needed a piece of granite". A chromosome is a natural object, and a missing piece of it is a portion of a natural object.
Wait, let's consider Sense 1: "a separate part of a whole". But Sense 3 specifically mentions "natural object". A chromosome is a natural object.
Let's re-read Sense 3: "a portion of a natural object".
Is a chromosome a natural object? Yes.
Is it Sense 3? Let's check Sense 1: "a separate part of a whole".
Let's check the examples for Sense 3: "they analyzed the river into three parts; he needed a piece of granite".
What about Sense 1: "an important piece of the evidence".
In the context: "a bit of chromosome 13 was missing. He assumed the missing piece contained a gene..."
"bit" is used in the previous sentence: "a bit of chromosome 13".
Sense 3 has "part" as a synonym.
Let's consider "piece of granite" -> natural object. Chromosome is a natural object.
Therefore, Sense 3 is the best fit.
Let's double check if there's any other sense.
Sense 5: "an instance of some kind" (bit). "a bit of good luck". Not physical.
Sense 3 is "a portion of a natural object".
I will choose 3.
Wait, let's look at Sense 1 again. "a separate part of a whole".
Is chromosome a natural object? Yes.
I'll go with 3.
Let's review the exact text: "a bit of chromosome 13 was missing. He assumed the missing piece contained a gene..."
"piece" here means a physical portion of the chromosome.
Sense 3: "a portion of a natural object".
Yes, 3 is the most specific and accurate.

reasoning_content:
The target word is "contained" in the context: "He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer."
The missing piece (of chromosome 13) included or had as a component a gene or genes.
Let's look at the candidate senses:
1. include or contain; have as a component (incorporate, comprise) - "The record contains many old songs from the 1930's"
2. contain or hold; have within (hold, bear, carry) - "The jar carries wine; The canteen holds fresh water"
3. lessen the intensity of; temper; hold in restraint
4. be divisible by
5. be capable of holding or containing
6. hold back, as of a danger or an enemy

Sense 1: "include or contain; have as a component". A piece of chromosome contains a gene. This fits "have as a component".
Sense 2: "contain or hold; have within". This is more about physical containers (jar, canteen).
Sense 1 is the best fit for a part containing a component (a gene).

Let's double check.
"the missing piece contained a gene or genes" -> the piece has the gene as a component.
Sense 1: include or contain; have as a component.
Sense 2: contain or hold; have within.

Is a chromosome piece a container? No, it's a part that has a component.
Sense 1 is the most appropriate.
Let's review the examples for Sense 1: "A totally new idea is comprised in this paper; The record contains many old songs from the 1930's".
This matches "the missing piece contained a gene or genes".

Therefore, sense 1.
End of thought.

reasoning_content:
The target word is "loss" in the 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 missing piece of a chromosome, which means a gene or genes are lost.
Sense 1: something that is lost. Examples: the car was a total loss; loss of livestock left the rancher bankrupt.
Sense 2: gradual decline in amount or activity.
Sense 3: the act of losing someone or something.
Sense 4: the disadvantage that results from losing something.
Sense 5: the experience of losing a loved one.
Sense 6: the amount by which the cost of a business exceeds its revenue.
Sense 7: military personnel lost by death or capture.
Sense 8: euphemistic expressions for death.

In the context, "whose loss had a critical role" refers to the missing piece (the gene or genes) being lost. It is "something that is lost".
Wait, let's look at Sense 1: "something that is lost". The missing piece contained a gene whose loss (the thing that is lost, i.e., the gene itself, or the state of being lost).
Wait, "whose loss" -> the loss of the gene. Is it the act of losing (Sense 3) or something that is lost (Sense 1)?
"loss of livestock" -> livestock is lost.
"loss of a gene" -> the gene is lost.
Let's check Sense 1: "something that is lost".
Let's check Sense 3: "the act of losing someone or something".
"whose loss had a critical role" -> the fact that it was lost, or the thing that was lost?
"loss of livestock" is Sense 1. "loss of a gene" is similar to "loss of livestock". The gene is the thing that is lost.
Wait, "loss" in "whose loss had a critical role" could be the state of being lost or the thing that is lost.
Let's consider "loss of livestock" (Sense 1). The livestock is the thing that is lost.
"loss of a gene" -> the gene is the thing that is lost.
Let's look at Sense 1: "something that is lost".
Is it Sense 1? Yes, "loss of livestock" is Sense 1. "loss of a gene" is analogous.
Let's double check Sense 1 vs Sense 3.
Sense 3: "the act of losing someone or something". Example: "everyone expected him to win so his loss was a shock".
Sense 1: "something that is lost". Example: "loss of livestock left the rancher bankrupt".
In "whose loss had a critical role", it refers to the missing piece/gene. The gene is the thing that is lost.
Therefore, Sense 1 is the best fit.
Let's review the context: "He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer."
The gene is the thing that is lost.
So Sense 1.
Let's confirm.
"loss of livestock" -> livestock is lost.
"loss of a gene" -> gene is lost.
Sense 1 is "something that is lost".
I will output 1.

reasoning_content:
The target word is "critical" in the context: "He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer."
The phrase is "critical role".
Let's look at the candidate senses:
1. tendency to find errors (critical attitude)
2. abrupt change, chain reaction (critical temperature, critical mass)
3. careful evaluation (critical reading)
4. urgently needed; absolutely necessary (vital, critical element of the plan)
5. forming or having the nature of a turning point or crisis (decisive, critical point in the campaign, critical test)
6. state of crisis or emergency (critical shortage, critical illness)
7. involving critics or criticism (critical acclaim)

"critical role" means a crucial, decisive, or absolutely necessary role.
Wait, let's distinguish between 4 and 5.
Sense 4: "urgently needed; absolutely necessary" (synonyms: vital, examples: a critical element of the plan)
Sense 5: "forming or having the nature of a turning point or crisis" (synonyms: decisive, examples: a critical point in the campaign, the critical test)

"critical role" is very similar to "critical element of the plan" (sense 4).
Let's check the examples for sense 4: "a critical element of the plan".
"critical role" -> "vital role" or "crucial role".
Is it sense 4 or 5?
"whose loss had a critical role in setting off the cancer."
Wait, "critical role" means it was essential or vital.
Let's see: "critical element of the plan" is sense 4.
"critical role" is often synonymous with "vital role" or "crucial role".
Sense 4: "urgently needed; absolutely necessary" (vital).
Sense 5: "forming or having the nature of a turning point or crisis" (decisive).
A "critical role" in setting off the cancer means it was an essential/vital part of the process.
Let's look at sense 4: "urgently needed; absolutely necessary".
Let's look at sense 5: "forming or having the nature of a turning point or crisis".
"critical role" -> "vital role".
I will choose sense 4.
Wait, let's re-read the context: "whose loss had a critical role in setting off the cancer."
Could it be sense 5? "decisive role"?
"critical role" is a very common collocation.
In WordNet, "critical" as "vital" is sense 4.
Let's check WordNet for "critical role".
Actually, "critical" meaning "vital" or "crucial" is often sense 4 or 5.
Sense 4: "urgently needed; absolutely necessary" (vital). Example: "a critical element of the plan".
Sense 5: "forming or having the nature of a turning point or crisis" (decisive). Example: "a critical point in the campaign".
"critical role" is closer to "critical element" (sense 4).
Let's choose 4.
Wait, "critical role" could be "decisive role". But "vital" is a synonym for sense 4. "vital role" is a very common phrase.
Let's go with 4.
Let's double check. "critical role" -> "vital role".
Yes, sense 4.
"urgently needed; absolutely necessary" -> "vital".
I'll output 4.

Sense 3: "what something is used for" (function, purpose, use).
Let's check the examples: "the function of an auger is to bore holes; ballet is beautiful but what use is it?"
Is it sense 3? Yes, "role" here means "function" or "purpose".
Let's re-read sense 1: "the actions and activities assigned to or required or expected of a person or group". This is for people or groups.
Sense 3 is for "what something is used for" or "function, purpose, use". The loss of a gene has a critical function/purpose/use in setting off the cancer.
Therefore, sense 3 is the best fit.
Let's double check. "critical role" -> "critical function".
Yes, sense 3.

reasoning_content:
The target word is "setting off" (lemma: set_off).
Context: "He assumed the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer."
Meaning: causing the cancer to begin, triggering the cancer.
Let's look at the candidate senses:
1. put in motion or move to act (trip, actuate, trigger, activate, spark off, spark) - "trigger a reaction"
2. leave (depart, part, start, start out, set forth, set out)
3. direct attention to, as if by means of contrast (bring out)
4. cause to burst with a violent release of energy (explode, detonate, blow up)
5. make up for (cancel, offset)
6. set in motion or cause to begin (The guide set the tour off to a good start)
7. provoke or stir up (incite, instigate, stir up)

Wait, "setting off the cancer" means triggering or causing it to begin.
Sense 1: put in motion or move to act (trigger, spark off). "trigger a reaction" -> "setting off the cancer" (triggering the cancer).
Sense 6: set in motion or cause to begin. "The guide set the tour off to a good start".
Sense 7: provoke or stir up.

Let's look at Sense 1: "put in motion or move to act" synonyms: trip, actuate, trigger, activate, spark off, spark. "trigger a reaction".
"setting off the cancer" is like triggering a reaction or a process.
Is it sense 1 or sense 6?
Sense 1: set_off%2:36:00:: put in motion or move to act.
Sense 6: set_off%2:30:01:: set in motion or cause to begin.
Wait, "setting off" in "setting off the cancer" is more like "triggering" or "sparking off".
Let's check the examples for sense 1: "trigger a reaction; actuate the circuits".
"setting off the cancer" -> triggering the cancer.
Sense 1 is "put in motion or move to act".
Sense 6 is "set in motion or cause to begin".
Let's consider "spark off" or "trigger". "trigger a reaction" is very close to "setting off the cancer".
Wait, sense 1 has "spark off", "trigger".
Let's see: "setting off" the cancer.
Is it sense 1? Yes, "trigger" is a synonym.
Let's check sense 1: set_off%2:36:00::
Let's check sense 6: set_off%2:30:01::
"set in motion or cause to begin"
Actually, "set off" meaning "trigger" is sense 1.
"set off" meaning "cause to begin" is sense 6.
But "setting off the cancer" is like triggering a reaction.
Let's look at the synonyms for sense 1: trip, actuate, trigger, activate, spark off, spark.
"spark off" is a very close synonym to "set off" in this context.
"trigger a reaction" -> "setting off the cancer".
I will choose sense 1.
Wait, let's re-read sense 1: "put in motion or move to act".
Sense 6: "set in motion or cause to begin".
Is "setting off the cancer" causing it to begin? Yes.
But "trigger" is explicitly in sense 1. "spark off" is in sense 1.
"setting off" = "triggering".
I'll go with 1.
Let's double check. "setting off the cancer" -> triggering the cancer.
Sense 1: put in motion or move to act.
Synonyms: trip, actuate, trigger, activate, spark off, spark.
Examples: trigger a reaction; actuate the circuits.
This perfectly matches "setting off the cancer" (triggering a reaction/disease).
I will output 1.

Context:
Back then, scientists had no way of ferreting out specific genes, but under a microscope they could see the 23 pairs of chromosomes in the cells that contain the genes. Occasionally, gross chromosome damage was visible. Dr. Knudson 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 cancer. But he did not <t>know</t> which gene or genes had disappeared. Then, a scientific team led by molecular geneticist Webster Cavenee, then at the University of Utah, found the answer.

reasoning_content:
The target word is "know" in the context: "But he did not <t>know</t> which gene or genes had disappeared."
The context is about possessing knowledge or information about a specific fact (which gene or genes had disappeared).
Sense 1: be cognizant or aware of a fact or a specific piece of information; possess knowledge or information about. Examples: I know that the President lied to the people; I want to know who is winning the game!
Sense 3: be aware of the truth of something; have a belief or faith in something; regard as true beyond any doubt.
Sense 1 fits perfectly: "he did not know which gene or genes had disappeared" -> he did not possess knowledge or information about which gene had disappeared.
Let's double check Sense 1 vs Sense 3.
Sense 1: "be cognizant or aware of a fact or a specific piece of information; possess knowledge or information about"
Sense 3: "be aware of the truth of something; have a belief or faith in something; regard as true beyond any doubt"
"know which gene or genes had disappeared" is about possessing information about a specific piece of information (which gene).
Therefore, Sense 1 is the best fit.
Let's review the examples for Sense 1: "I want to know who is winning the game!" -> "know which gene or genes had disappeared". This matches the structure "know + wh-clause".
Sense 1 is the correct choice.

The target word is "scientific" in the context: "Then, a scientific team led by molecular geneticist Webster Cavenee, then at the University of Utah, found the answer."
The phrase is "scientific team".
Sense 1: of or relating to the practice of science (e.g., scientific journals)
Sense 2: conforming with the principles or methods used in science (e.g., a scientific approach)

A "scientific team" is a team of scientists, or a team relating to the practice of science.
Wait, "scientific team" means a team of scientists, or a team engaged in the practice of science.
Sense 1: "of or relating to the practice of science" -> scientific journals, scientific team.
Sense 2: "conforming with the principles or methods used in science" -> scientific approach, scientific method.

Let's look at the context: "a scientific team led by molecular geneticist Webster Cavenee". This means a team of scientists, or a team that practices science.
Sense 1 fits "of or relating to the practice of science".
Sense 2 fits "conforming with the principles or methods used in science".
A team is not "conforming with the principles or methods used in science" as much as it is "of or relating to the practice of science" (i.e., a team of scientists).
Let's check WordNet for "scientific".
Sense 1: of or relating to the practice of science. "scientific journals"
Sense 2: conforming with the principles or methods used in science. "a scientific approach"

"scientific team" -> a team of scientists. This is "of or relating to the practice of science".
Therefore, sense 1 is the best fit.
Let's double check.
"scientific team" = a team that does science.
Sense 1: of or relating to the practice of science.
Sense 2: conforming with the principles or methods used in science.
I will choose 1.
Wait, let's consider if "scientific team" could be sense 1. Yes, "scientific" modifying "team" means the team is involved in the practice of science.
I'll output 1.

Let's check sense 8: "make a discovery, make a new finding". Examples: "Roentgen discovered X-rays; Physicists believe they found a new elementary particle".
Let's check sense 4 again. "establish after a calculation, investigation, experiment, survey, or study". The team used a battery of newly developed "gene probes" to track a gene's presence. This is an experiment/investigation. They established the answer.
Is it sense 4? "The physicist who found the elusive particle won the Nobel Prize" is an example for sense 4.
Wait, "found the answer" -> "determine, find out, ascertain".
Let's see: "Then, a scientific team led by molecular geneticist Webster Cavenee, then at the University of Utah, found the answer."
"found the answer" = determined the answer, ascertained the answer.
Sense 4: establish after a calculation, investigation, experiment, survey, or study.

4. sense_key=find%2:32:00:: | definition=establish after a calculation, investigation, experiment, survey, or study | synonyms=determine, find out, ascertain | examples=find the product of two numbers; The physicist who found the elusive particle won the Nobel Prize

Is there any other sense?
"discover or determine the existence, presence, or fact of" (sense 2)
"make a discovery, make a new finding" (sense 8)
"make a discovery" (sense 9)

"found the answer" -> "determine, find out, ascertain".
"find out the answer" is a very common collocation.
Sense 4 has "determine, find out, ascertain".
I will go with sense 4.
Let's double check.
"Then, a scientific team led by molecular geneticist Webster Cavenee, then at the University of Utah, found the answer."
They established the answer after an investigation/experiment.
Yes, sense 4 is the best fit.
Another option: sense 8 "make a discovery, make a new finding". But "found the answer" is more about ascertaining/determining.
Sense 4 is "establish after a calculation, investigation, experiment, survey, or study".
I am confident in 4.
Let's check if "find the answer" is typically sense 4.
Yes, "find out" or "ascertain" the answer.
I will output 4.

Context:
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 cancer. But he did not know which gene or genes had disappeared. Then, a scientific team led by molecular geneticist Webster Cavenee, then at the University of Utah, found the <t>answer</t>. The team used a battery of the newly developed "gene probes, "snippets of genetic material that can track a gene's presence in a cell.

Candidate senses:

Context: "Then, a scientific team led by molecular geneticist Webster Cavenee, then at the University of Utah, found the answer. The team used a battery of the newly developed "gene probes, "snippets of genetic material that can track a gene's presence in a cell."
The context is about finding a solution to a problem (which gene or genes had disappeared).
Sense 1: a statement made to reply to a question or request.
Sense 2: a statement that solves a problem or explains how to solve the problem. Synonyms: solution, result, resolution, solvent. Examples: they were trying to find a peaceful solution; the answers were in the back of the book.
Sense 3: the speech act of replying to a question.
Sense 4: legal pleading.
Sense 5: a nonverbal reaction.

The team "found the answer" to the problem of which gene had disappeared. This matches Sense 2: a statement that solves a problem or explains how to solve the problem (solution).

Let's check Sense 2.
"found the answer" -> found the solution.
Yes, Sense 2 is the best fit.
Context: "But he did not know which gene or genes had disappeared. Then, a scientific team ... found the answer."
This is a solution to a problem.
Sense 2 is the correct choice.
