The context describes genetic abnormalities in chromosome 13 found in cancer cells. The passage explicitly mentions analyzing chromosomal material for imperfections in a biological system. This aligns with sense 1 ("an imperfection in a bodily system"), which covers genetic and cellular abnormalities, similar to the cited examples of "visual defects" and "defects in the lungs." The other senses refer to physical object flaws, cosmetic blemishes, or abstract deficiencies—none of which fit the medical/genetic context.

reasoning_content:
Let me analyze the context and the candidate senses for "defects" in this passage.

Context: The passage is about genetic analysis of cancer cells. Specifically, it mentions:
- A missing piece of chromosome 13
- A gene or genes whose loss is related to cancer
- Using gene probes to track genes in cells
- Finding "defects in the second copy of chromosome 13"

This is clearly a biological/medical context. The "defects" refer to abnormalities in the chromosome structure - specifically, genetic imperfections or abnormalities in the chromosomal material.

Let me evaluate each sense:

1. **sense_key=defect%1:26:01::** "an imperfection in a bodily system" - Examples: visual defects, detection of defects in the lungs. This is medical/bodily defects.

2. **sense_key=defect%1:07:01::** "a failing or deficiency" - Example about interpretation. This is more abstract.

3. **sense_key=defect%1:26:00::** "an imperfection in an object or machine" - Examples: flaw in crystal, manufacturer defects. This is about physical objects.

4. **sense_key=defect%1:07:00::** "a mark or flaw that spoils appearance" - About facial blemishes. This is about cosmetic/appearance defects.

The context is about defects in chromosome 13, which is part of the bodily/genetic system. This is clearly within a medical/biological context about bodily systems, not about physical objects or appearance marks.

Sense 1 "an imperfection in a bodily system" with examples of "visual defects" and "defects in the lungs" seems to be the best fit. These are medical defects in bodily systems, similar to genetic defects in chromosomes.

The answer should be sense_index: 1

The target word "second" in the phrase "the second copy of chromosome 13" is used as an ordinal number indicating position or sequence. It refers to the copy that comes after the first copy, which is precisely the definition of sense 1 (coming next after the first in position). Sense 2, relating to musical subordinate parts, is completely inapplicable in this medical/genetic context.

reasoning_content:
The target word is "second" in the context of discussing chromosome 13 in a cancer research narrative.

The sentence is: "By analyzing cells extracted from eye tumors, they found defects in the second copy of chromosome 13 in the exact area as in the first copy of the chromosome."

Let me analyze the two candidate senses:

1. sense_key=second%5:00:00:ordinal:00 | definition=coming next after the first in position in space or time or degree or magnitude | synonyms=2nd, 2d
   - This is the ordinal sense meaning "second" as in 1st, 2nd, 3rd, etc.
   - In the context "the second copy of chromosome 13," this clearly refers to the ordinal position - the second occurrence or instance of chromosome 13.
   - Synonyms 2nd, 2d fit perfectly here.

2. sense_key=second%3:00:00:: | definition=a part or voice or instrument or orchestra section lower in pitch than or subordinate to the first | examples=second flute; the second violins
   - This refers to musical instruments/sections that are subordinate to the first.
   - This doesn't fit the context at all - we're talking about chromosomes, not music.

The context is clearly scientific/medical, talking about two copies of a chromosome. "The second copy" is referring to the ordinal position - the copy that comes second after the first. This is definitely sense 1, the ordinal sense.

The context is describing chromosome 13 in genetic analysis. The "second copy of chromosome 13" refers to one of the two similar/identical versions of that chromosome present in cells (humans typically have two copies of each chromosome, one from each parent). This matches sense 2: "a thing made to be similar or identical to another thing," which directly applies to the biological concept of duplicate genetic material.

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

The sentence is: "By analyzing cells extracted from eye tumors, they found defects in the second copy of chromosome 13 in the exact area as in the first copy of the chromosome."

The context is about genetics and chromosomes. The text is discussing chromosome 13 - the cell has two copies of it. This is referring to the fact that humans have two copies of each chromosome (one from each parent).

Let me examine each candidate sense:

1. sense_key=copy%1:10:00:: | definition=a reproduction of a written record (e.g. of a legal or school record) | synonyms=transcript
   - This is about written records, not chromosomes. Not the right sense.

2. sense_key=copy%1:06:00:: | definition=a thing made to be similar or identical to another thing | examples=she made a copy of the designer dress; the clone was a copy of its ancestor
   - This definition fits! In genetics, each person has two copies of each chromosome - they are similar/identical versions. One is from the mother and one from the father. This is about "a thing made to be similar or identical to another thing" - in this case, the second copy of chromosome 13 is similar to the first copy.

3. sense_key=copy%1:10:01:: | definition=matter to be printed; exclusive of graphical materials | synonyms=written matter
   - This is about printed materials, not chromosomes. Not the right sense.

4. sense_key=copy%1:10:02:: | definition=material suitable for a journalistic account | examples=catastrophes make good copy
   - This is about journalistic material, not chromosomes. Not the right sense.

The answer is clearly sense 2 (sense_key=copy%1:06:00::), which refers to "a thing made to be similar or identical to another thing." In biological/genetic context, the second copy of a chromosome is indeed similar/identical to the first copy (both are copies of the chromosome).
The sense index is 2.

In this context, "exact" modifies "area" to describe the precise, corresponding location in the chromosome where defects were found in the second copy as in the first copy. This aligns with sense 1, which emphasizes "strict and particular and complete accordance with fact" - the defects appear in the same, precisely matching area. The phrase "exact area" functions similarly to the example "exact copy" - both convey a complete, point-for-point correspondence.

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

The sentence is: "By analyzing cells extracted from eye tumors, they found defects in the second copy of chromosome 13 in the exact area as in the first copy of the chromosome."

Here, "exact" is being used to describe the area - it means that the defects were found in the same specific location/area in the second copy as in the first copy. The word is describing a precise correspondence or match.

Now let me look at the two candidate senses:

1. Sense 1: "marked by strict and particular and complete accordance with fact" with examples like "an exact mind; an exact copy"
   - This sense emphasizes strict adherence to fact and completeness
   - "exact copy" is a perfect example - something that matches completely

2. Sense 2: "(of ideas, images, representations, expressions) characterized by perfect conformity to fact or truth; strictly correct" with synonyms "accurate, precise"
   - This sense is about conformity to fact or truth
   - The examples are "precise image" and "precise measurement"

In the context, "exact area" means the same, specific area - it's about precision and correspondence. The word is modifying "area" to indicate it's the specific/same location.

Both senses seem relevant, but Sense 1 seems to be the better fit because:
- It directly describes something (an area) that matches or corresponds exactly
- "exact copy" is a direct parallel - the defects appear in the exact (same) area
- The sense emphasizes "complete accordance" which fits the meaning of "the same area"

Sense 2 focuses more on representations and expressions being correct, which seems less directly applicable here.

I believe Sense 1 is the best choice.

The context describes comparing defects found in "the second copy of chromosome 13" with "the first copy." Here, "first" is functioning as an ordinal number indicating the initial unit in a series (first vs. second). This is the ordinal sense that corresponds to "1st" in a numbered sequence.

reasoning_content:
Let me analyze the context carefully. The sentence is:

"By analyzing cells extracted from eye tumors, they found defects in the second copy of chromosome 13 in the exact area as in the <t>first</t> copy of the chromosome."

The word "first" is being used here to distinguish between two copies of chromosome 13 - the "first copy" and the "second copy" mentioned in the previous part of the sentence.

Let me look at each candidate sense:

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
   - This is about preceding in time, space, or degree. It's the general temporal/spatial sense.

2. sense_key=first%5:00:00:ordinal:00 | definition=indicating the beginning unit in a series | synonyms=1st
   - This is the ordinal number sense - it indicates position in a series (1st, 2nd, 3rd, etc.)

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
   - This is about something that initiates or opens

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
   - This is about something that begins

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
   - This is about ranking highest

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
   - This is about music/hierarchical rank in orchestral terms

In this context, "first" functions as an ordinal number distinguishing one chromosome copy from another in a paired set. Sense 2 captures this precisely—it's the ordinal sense that marks position in a sequence, which is exactly how the word operates when contrasting the first copy with the second copy.

The target word "copy" in this genetic context refers to one of the two instances of chromosome 13. This matches sense 2: "a thing made to be similar or identical to another thing." In cellular biology, organisms typically have two copies of each chromosome (one from each parent), and they are essentially identical or very similar to each other. The context explicitly compares "the second copy of chromosome 13" to "the first copy," indicating that "copy" means one instance or version that is identical or near-identical to another.

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

The sentence is: "By analyzing cells extracted from eye tumors, they found defects in the second copy of chromosome 13 in the exact area as in the first copy of the chromosome."

In this context, "copy" refers to one of two versions of chromosome 13. Humans have two copies of each chromosome (diploid organisms). Here, the word "copy" is being used to mean "one instance" or "one version" of a chromosome.

Let me examine 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 documents/records, not chromosomes. Not appropriate.

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 talks about something made to be similar to another thing. In the context of chromosomes, the second copy is indeed similar/identical to the first copy. This seems fitting.

3. **sense_key=copy%1:10:01::** - "matter to be printed; exclusive of graphical materials" - This is about printing/publishing, not relevant.

4. **sense_key=copy%1:10:02::** - "material suitable for a journalistic account" - This is about journalism, not relevant.

The best fit is sense 2, which is about "a thing made to be similar or identical to another thing." In the biological context, one chromosome copy is essentially identical to another copy of the same chromosome (though they may have different mutations). This matches the definition of sense 2.

The answer should be: {"sense_index": 2}

The word "finding" in this context refers to the discovery or result of the scientific research—specifically, the defects found in chromosome 13 and the conclusions drawn from them. This is a concrete discovery that "riveted medicine," not the abstract process of determining properties or a legal decision. Sense 3, "something that is found," matches perfectly with the usage here as a significant scientific discovery.

reasoning_content:
Let me analyze the target word "finding" in the given context.

The sentence is: "The finding riveted medicine. It was the first time anyone had showed that the loss of both copies of the same gene could lead to the eruption of a cancer."

Context clues:
1. The "finding" refers to a discovery made by the scientific team
2. They "found defects in the second copy of chromosome 13"
3. The finding is described as something that "riveted medicine" - meaning it captured attention and was significant
4. It's being presented as a discovery/result of scientific research

Now let me look at the three senses:

1. Sense 1: "the act of determining the properties of something, usually by research or calculation" with synonyms "determination". Examples: "the determination of molecular structures"
   - This refers to the ACT of determining/finding, not the result itself

2. Sense 2: "the decision of a court on issues of fact or law"
   - This is clearly a legal definition, doesn't fit this scientific context

3. Sense 3: "something that is found" with examples about findings in gastrointestinal tract and archaeological findings
   - This refers to the RESULT or DISCOVERY itself, not the act
   - This fits perfectly - it's describing the discovery/result that was found

In the context, "finding" is used as a noun referring to the actual discovery or result of the research - the fact that they found defects in chromosome 13. It's not referring to the act of finding, but to what was found (the discovery itself).

Therefore, the best sense is sense 3.

"The finding riveted medicine."

This is in a scientific context discussing a major breakthrough in understanding cancer genetics. The team discovered something fundamental about how genes relate to cancer development, and this discovery "riveted medicine" - meaning it captured the attention and interest of the field of medicine.

The context uses "first time" to indicate that this was the earliest/earliest instance in time when anyone had demonstrated this discovery about cancer genes. This matches sense 1, which defines "first" as "preceding all others in time or space or degree," with the example "the first day of spring" showing the same temporal meaning.

reasoning_content:
Let me analyze the context for the word "first" in the sentence:

"It was the <t>first</t> time anyone had showed that the loss of both copies of the same gene could lead to the eruption of a cancer."

The context is saying that this was the first time (the earliest time, the initial instance) that anyone had demonstrated something. It's referring to it being the earliest occurrence of this discovery.

Let me examine each sense:

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
   - This fits: "the first day of spring" is similar to "the first time" - it's talking about something preceding all others in time

2. sense_key=first%5:00:00:ordinal:00 | definition=indicating the beginning unit in a series | synonyms=1st
   - This could work, but it's more about ordinal position

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
   - This is about something that initiates or sets in motion

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
   - This is about serving to begin

5. sense_key=first%5:00:00:best:00 | definition=ranking above all others | synonyms=foremost, world-class
   - This is about quality/rank, not about time

6. sense_key=first%5:00:03:: | definition=highest in pitch or chief among parts or voices or instruments or orchestra sections
   - This is about music, not applicable

The most appropriate sense is #1, which says "preceding all others in time or space or degree" and gives "the first day of spring" as an example. This directly parallels "the first time" in the context.
While the ordinal sense could technically apply, sense 1 more precisely captures the temporal precedence at play here. The answer is sense 1.

The phrase "It was the first time anyone had showed..." uses "time" to mean "an instance or single occasion for some event." The context is describing the first occasion when this particular discovery was made, which directly matches sense 1's definition and examples like "this time he succeeded."

reasoning_content:
Let me analyze the context and find the best sense for "time" in this sentence:

"It was the first time anyone had showed that the loss of both copies of the same gene could lead to the eruption of a cancer."

The sentence is saying "It was the first [instance/occasion] when anyone had showed..."

Looking at the candidate senses:

1. sense_key=time%1:11:00:: | definition=an instance or single occasion for some event | synonyms=clip | examples=this time he succeeded; he called four times
   - This fits perfectly. It's talking about a specific occasion/instance when something happened.

2. sense_key=time%1:28:05:: | definition=a period of time considered as a resource under your control and sufficient to accomplish something
   - Doesn't fit. The sentence isn't about time as a resource.

3. sense_key=time%1:28:00:: | definition=an indefinite period (usually marked by specific attributes or activities)
   - Doesn't fit well. It's not talking about a period with specific attributes.

4. sense_key=time%1:28:06:: | definition=a suitable moment
   - Doesn't fit. It's not about a suitable moment.

5. sense_key=time%1:03:00:: | definition=the continuum of experience in which events pass from the future through the present to the past
   - Too abstract and philosophical. Doesn't fit.

6. sense_key=time%1:11:01:: | definition=a person's experience on a particular occasion
   - Could fit, but less precise than sense 1.

The remaining senses—clock readings, physics coordinates, rhythmic divisions, and imprisonment duration—all lack relevance to this context. The first sense clearly captures what's intended: a discrete moment when a particular discovery occurred.

The context describes a scientific discovery where researchers demonstrated/proved a causal relationship through experimental evidence. The phrase "showed that the loss of both copies of the same gene could lead to the eruption of a cancer" is establishing the validity of a scientific principle through experimental analysis. This matches sense 2: "establish the validity of something, as by an example, explanation or experiment," with synonyms like "prove" and "demonstrate" that perfectly fit the scientific context.

reasoning_content:
Let me analyze the context and find the best sense for "showed" in this sentence.

The sentence is: "It was the first time anyone had showed that the loss of both copies of the same gene could lead to the eruption of a cancer."

The structure is: "showed that [something could lead to something else]"

This is being used in a scientific context where the researchers demonstrated/proved a causal relationship through their findings.

Let me go through the candidate senses:

1. "give an exhibition of to an interested audience" - Not quite, this isn't about exhibiting something.

2. "establish the validity of something, as by an example, explanation or experiment" - This fits well. The team showed/proved that this genetic loss could lead to cancer. The synonyms include "prove, demonstrate, establish" which all fit.

3. "provide evidence for" - This also could fit, but it's more about providing evidence than establishing validity.

4. "make visible or noticeable" - Too general and not quite right for this scientific context.

5. "show in, or as in, a picture" - Not relevant.

6. "give expression to" - Not relevant.

7. "indicate a place, direction, person, or thing" - Not relevant.

8. "be or become visible or noticeable" - Not relevant.

9. "indicate a certain reading; of gauges and instruments" - Not relevant.

10. "give evidence of, as of records" - Could work, but less specific than sense 2.

11. "take (someone) to their seats" - Not relevant.

12. "finish third or better in a horse or dog race" - Not relevant.

Between sense 2 and sense 3, sense 2 ("establish the validity of something, as by an example, explanation or experiment") seems more precise. The team demonstrated the validity of the hypothesis that loss of both gene copies could lead to cancer through their experimental findings.
Sense 2 is the best fit here.

Let me analyze the context carefully. The target word is "loss" in this sentence:

"It was the first time anyone had showed that the loss of both copies of the same gene could lead to the eruption of a cancer."

The context is about a genetic discovery where researchers found that the loss (disappearance/absence) of both copies of the same gene could lead to cancer development.

Let me evaluate each sense:

1. "something that is lost" - This could fit, but the examples are about concrete objects like "the car" or "livestock"
2. "gradual decline in amount or activity" - The examples mention "weight loss" and "loss of business" - this is about a gradual decrease
3. "the act of losing someone or something" - This is about the action/event of losing something. The examples show "loss was a shock"
4. "the disadvantage that results from losing something" - About deprivation/disadvantage
5. "the experience of losing a loved one" - About losing a person, death-related
6. "the amount by which cost exceeds revenue" - Business/accounting term
7. "military personnel lost by death or capture" - Military context
8. "euphemistic expressions for death" - Death-related

In the genetic context, "loss of both copies of the same gene" refers to the situation where both copies are missing or non-existent. This is about the act or event of the genes disappearing/being lost, or the state of them being absent.

Sense 3 "the act of losing someone or something" seems most appropriate - it's referring to the event/act of the genes being lost (disappearing). The definition "the act of losing someone or something" fits well with genes being lost.

Sense 2 is about gradual decline, which doesn't quite fit - this is about the genes being gone, not a gradual process.

Sense 1 "something that is lost" is close but the examples are about concrete objects.

I think sense 3 is the best fit - it's about the act of losing (the genes being lost/disappeared).

The word "copies" in this context refers to instances or units of a chromosome. In genetics, organisms typically have multiple copies of each chromosome (humans have two - one from each parent). This sense aligns with "a thing made to be similar or identical to another thing," where each copy of chromosome 13 is structurally similar or identical to the other copy of that same chromosome.

reasoning_content:
Let me analyze the context to understand what "copies" means in this sentence.

The context is about genetics and chromosome analysis. The key sentence is: "By analyzing cells extracted from eye tumors, they found defects in the second copy of chromosome 13 in the exact area as in the first copy of the chromosome."

Here, "copy" is referring to one instance of a chromosome. In genetics, humans typically have two copies of each chromosome - one from each parent. So "copy" here refers to one instance or unit of a chromosome.

Now let's evaluate the candidate senses:

1. sense_key=copy%1:10:00:: | definition=a reproduction of a written record (e.g. of a legal or school record) | synonyms=transcript
   - This is about reproductions of written records. Not applicable here.

2. sense_key=copy%1:06:00:: | definition=a thing made to be similar or identical to another thing | examples=she made a copy of the designer dress; the clone was a copy of its ancestor
   - This refers to something made to be similar or identical to another thing. In genetics, one copy of a chromosome is indeed similar/identical to another copy of that chromosome. This seems like the best fit.

3. sense_key=copy%1:10:01:: | definition=matter to be printed; exclusive of graphical materials | synonyms=written matter
   - This is about printing/written matter. Not applicable here.

4. sense_key=copy%1:10:02:: | definition=material suitable for a journalistic account | examples=catastrophes make good copy
   - This is about journalistic material. Not applicable here.

The best sense is clearly sense 2 (copy%1:06:00::), which refers to "a thing made to be similar or identical to another thing." A chromosome copy is indeed one of multiple similar/identical instances of the same chromosome.

The context refers to "both copies of the same gene" - indicating the identical gene appearing in both chromosome 13 copies. This is a reference to identity (the exact same gene in both locations), not merely similarity, equality of value, or lack of change. Sense 1 ("same in identity") with its examples like "the same man I saw yesterday" best captures this usage.

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

In the sentence: "It was the first time anyone had showed that the loss of both copies of the same gene could lead to the eruption of a cancer."

The word "same" is referring to the gene mentioned earlier in the passage - specifically, both copies of chromosome 13 contained defects in "the exact area." The text is saying that both copies have defects in the identical/same gene.

Let me examine each sense:

1. "same in identity" - the exact same object/entity. This would mean it's literally the identical gene (by identity). Examples like "the same man I saw yesterday" suggest exact identity.

2. "closely similar or comparable in kind or quality or quantity or degree" - suggests similarity but not necessarily identity. The examples show comparable things (curtains the same color, girls the same age).

3. "equal in amount or value" - suggests equivalence in quantity/value. Examples show amounts being equal.

4. "unchanged in character or nature" - suggests something hasn't changed over time. Examples show persistence of a quality.

In context: "both copies of the same gene" - this refers to the same gene appearing in both copies of chromosome 13. It's the identical gene in both cases, not just similar ones. This is about identity, not about similarity, equality of amount, or unchangeability.

Sense 1 fits best: "same in identity" - it's the exact same gene (not just a similar one) in both chromosome copies.

Let me analyze the context and find the best sense for "lead" in this sentence:

"It was the first time anyone had showed that the loss of both copies of the same gene could <t>lead</t> to the eruption of a cancer."

The sentence is talking about the consequence or result of losing both gene copies - it leads to (causes/results in) cancer eruption.

Let me look at the candidate senses:

1. sense_key=lead%2:38:01:: - take somebody somewhere - NOT relevant
2. sense_key=lead%2:42:04:: - have as a result or residue - this is about leaving a physical mark/residue
3. sense_key=lead%2:42:12:: - tend to or result in - This looks like a good match. Example: "This remark lead to further arguments among the guests" - similar structure
4. sense_key=lead%2:38:00:: - travel in front of - NOT relevant
5. sense_key=lead%2:32:00:: - cause to undertake a certain action - about causing someone to do something
6. sense_key=lead%2:42:00:: - stretch out over a distance - NOT relevant
7. sense_key=lead%2:41:00:: - be in charge of - NOT relevant (though earlier in the text "led by molecular geneticist" uses a different sense)
8. sense_key=lead%2:42:01:: - be ahead of others - NOT relevant
9. sense_key=lead%2:41:12:: - be conducive to - Definition: "be conducive to" means to contribute to or lead to as a result. Example: "The use of computers in the classroom lead to better writing" - this is very similar!
10-14. Other senses not relevant

Sense 9 ("be conducive to") appears most fitting here. While both sense 3 and sense 9 convey causality, sense 9's framing of one thing being a contributing factor to an outcome aligns better with how genetic loss functions as a condition that promotes cancer development.

The context discusses how the loss of both copies of a gene leads to the "eruption" of cancer. In this medical/genetic context, "eruption" is used metaphorically to describe the sudden, violent occurrence of an undesirable condition (cancer), which directly matches sense 4: "a sudden violent spontaneous occurrence (usually of some undesirable condition)" with the synonym "outbreak." This is distinct from literal volcanic eruptions (senses 1, 3) and other unrelated senses (2, 5, 6).

reasoning_content:
Let me analyze the context to determine the correct sense of "eruption."

The context is about cancer development. The passage discusses how the loss of both copies of the same gene (specifically on chromosome 13) could lead to the "eruption" of cancer.

Let me consider each sense:

1. "the sudden occurrence of a violent discharge of steam and volcanic material" - This is clearly about volcanic eruptions. Not applicable here.

2. "symptom consisting of a breaking out and becoming visible" - This refers to skin rashes or similar medical symptoms appearing visibly.

3. "(of volcanos) pouring out fumes or lava" - Again volcanic, not applicable.

4. "a sudden violent spontaneous occurrence (usually of some undesirable condition)" - This refers to a sudden occurrence of something undesirable, like an outbreak. The example is "outbreak of hostilities."

5. "a sudden very loud noise" - Not applicable to cancer development.

6. "the emergence of a tooth as it breaks through the gum" - About teeth, not applicable.

In the context of cancer development, the word "eruption" is used metaphorically to mean the sudden occurrence or outbreak of cancer - an undesirable condition. This matches sense 4 best: "a sudden violent spontaneous occurrence (usually of some undesirable condition)" with synonyms like "outbreak, irruption."

The passage is saying that the loss of both gene copies led to the sudden emergence/outbreak of cancer, which fits sense 4 perfectly.

The context is clearly about medical genetics and tumor research. The passage discusses gene defects leading to "the eruption of a cancer," in the context of analyzing cells from eye tumors and molecular biology research. This is unambiguously referring to malignant tumors caused by abnormal cell division, which is sense 1. The other senses refer to astrological/astronomical concepts (zodiacs) or a genus of crabs, which are entirely inappropriate for this medical/scientific context.

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

The context is discussing:
- Gene research and tumor analysis
- A scientific team finding defects in chromosomes
- "The loss of both copies of the same gene could lead to the eruption of a cancer"
- This is about malignant growths/tumors

Looking at the candidate senses:
1. "any malignant growth or tumor caused by abnormal and uncontrolled cell division" - This is about the medical condition
2. "a person who is born while the sun is in Cancer" - Astrology sense
3. "a small zodiacal constellation" - Astronomy sense
4. "the fourth sign of the zodiac" - Astrology sense
5. "type genus of the family Cancridae" - Biological genus (genus of crabs)

Given the context is clearly about molecular genetics, tumors, gene defects, and medical research (mentioning "Fox Chase Cancer Research Center"), the target word "cancer" refers to the medical condition - a malignant growth or tumor.

This is clearly sense 1, which defines cancer as "any malignant growth or tumor caused by abnormal and uncontrolled cell division."

The answer should be {"sense_index": 1}

The context describes Dr. Knudson's emotional response to a major scientific breakthrough—the discovery that loss of both gene copies could cause cancer. His use of "extraordinarily satisfying" refers to the emotional gratification and relief from finally having found the answer to a puzzling medical question. This aligns with sense 2's definition of "providing freedom from worry," where the worry of the unknown has been resolved. Sense 1 about nourishment is inapplicable here.

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

The context is a scientist (Dr. Knudson) describing his reaction to a major scientific discovery. He found that the loss of both copies of the same gene could lead to cancer. The sentence is: "It was extraordinarily satisfying," says Dr. Knudson.

Let me look at the two candidate senses:

1. Sense 1: "providing abundant nourishment" with synonyms like hearty, solid, square, substantial and examples about meals and food. This is clearly about food/nutrition.

2. Sense 2: "providing freedom from worry" with synonyms comforting, cheering. This relates to emotional satisfaction and comfort.

In the context, Dr. Knudson is talking about his emotional reaction to making a scientific breakthrough - finding the answer to a major medical puzzle. He's expressing satisfaction in the sense of fulfillment, contentment, and emotional satisfaction from achieving something meaningful. This is NOT about food or nourishment.

Sense 2 ("providing freedom from worry") is more appropriate. When someone describes something as "satisfying" in the context of a major scientific discovery, they mean it was emotionally gratifying and comforting to finally have the answer. This aligns with the definition "providing freedom from worry" - the worry about not knowing the answer has been resolved.

The answer should be sense 2.

The context shows Dr. Knudson directly expressing his opinion in quoted speech: "It was extraordinarily satisfying." This is a straightforward case of expressing something in words, which matches the definition "express in words" with synonyms "state, tell." The examples provided for this sense (like "He said that he wanted to marry her") are structurally and functionally similar to the target usage.

reasoning_content:
Let me analyze the context and the target word "says" to determine the best sense.

The context is: "It was extraordinarily satisfying," says Dr. Knudson, now at Fox Chase Cancer Research Center in Philadelphia.

This is a direct quotation attribution - Dr. Knudson is speaking and expressing his opinion about the satisfaction of the discovery. He is expressing in words what he thinks/feels.

Let me review the candidate senses:

1. sense_key=say%2:32:00:: | definition=express in words | synonyms=state, tell | examples=He said that he wanted to marry her; tell me what is bothering you
   - This is "express in words" - general definition of saying something verbally

2. sense_key=say%2:32:01:: | definition=report or maintain | synonyms=allege, aver
   - This is more about claiming or alleging something, often with doubt

3. sense_key=say%2:32:03:: | definition=express a supposition | synonyms=suppose
   - This is for hypothetical statements

4. sense_key=say%2:42:00:: | definition=have or contain a certain wording or form | synonyms=read
   - This is about what text says, not about speaking

5. sense_key=say%2:32:04:: | definition=give instructions to or direct somebody to do something with authority | synonyms=order, tell, enjoin
   - This is about giving orders

6. sense_key=say%2:32:02:: | definition=speak, pronounce, or utter in a certain way | synonyms=pronounce, articulate, enounce, sound out, enunciate
   - This is about how something is said, pronunciation

7. sense_key=say%2:32:07:: | definition=communicate or express nonverbally
   - This is for non-verbal communication

8. sense_key=say%2:32:15:: | definition=utter aloud
   - This is just uttering something aloud

9. sense_key=say%2:32:13:: | definition=state as one's opinion or judgement; declare
   - This is stating one's opinion or judgment

10. sense_key=say%2:32:08:: | definition=recite or repeat a fixed text
    - This is about reciting memorized text

11. sense_key=say%2:32:09:: | definition=indicate
    - This is about indicating something

The most fitting sense is sense_key=say%2:32:13:: because Dr. Knudson is declaring his personal judgment about the satisfaction of the discovery. While sense_key=say%2:32:00:: (express in words) is also plausible, sense 13 better captures that he's specifically stating his opinion or assessment rather than just conveying information neutrally.

The word "now" in this context means "at the present moment," indicating Dr. Knudson's current position. The phrase "now at Fox Chase Cancer Research Center" describes where he is currently located, which aligns with the definition "at the present moment" and the example "the now-aging dictator" that similarly describes a current state or condition.

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

The sentence is: "It was extraordinarily satisfying," says Dr. Knudson, <t>now</t> at Fox Chase Cancer Research Center in Philadelphia.

In this context, "now" is describing Dr. Knudson's current location/position at the time of writing or speaking. The structure "says Dr. Knudson, now at Fox Chase Cancer Research Center" indicates that at present/currently, Dr. Knudson is at Fox Chase Cancer Research Center. This is describing his current state or position.

Let me review the candidate senses:

1. sense_key=now%4:02:05:: - "in the historical present; at this point in the narration of a series of past events" - This is about narrative present tense, doesn't fit.

2. sense_key=now%4:02:00:: - "in these times; nowadays, today" - This refers to contemporary times in general, but the usage here is more specific about the present moment/current state.

3. sense_key=now%4:02:02:: - "used to preface a command or reproof or request" - Doesn't fit, there's no command here.

4. sense_key=now%4:02:04:: - "at the present moment" - This fits well. "now at Fox Chase Cancer Research Center" means he is currently/at the present moment at that location.

5. sense_key=now%4:02:01:: - "without delay or hesitation; with no time intervening" - Doesn't fit, there's no urgency implied.

6. sense_key=now%4:02:07:: - "(prefatory or transitional) indicates a change of subject or activity" - This is used transitionally to change topics, doesn't fit.

7. sense_key=now%4:02:06:: - "in the immediate past" - Doesn't fit, we're talking about the present position, not the immediate past.
The most appropriate sense is #4, which captures the meaning of "at the present moment." Dr. Knudson's current affiliation with Fox Chase Cancer Research Center is what's being conveyed here.

The word "true" in this context means "consistent with fact or reality; not false." Dr. Knudson is asserting that the genetic principle he discovered in retinoblastoma—that loss of both copies of a gene leads to cancer—would be factually/actually applicable to all cancers. This is the basic epistemic sense of "true" referring to statements or propositions that accord with reality.

Let me analyze the context to determine the best sense for "true" in this sentence:

"I was convinced that what was <t>true</t> of retinoblastoma would be true for all cancers."

The context is about Dr. Knudson's research findings regarding cancer genetics. He found that loss of both copies of the same gene could lead to cancer in retinoblastoma cases, and he was convinced this principle would apply to all cancers.

The word "true" here is being used in the sense of "applicable" or "correct/accurate" - he's saying that what is correct/applicable about retinoblastoma would be correct/applicable for all cancers.

Let me examine the candidate senses:

1. "consistent with fact or reality; not false" - This seems to fit. The statement "what was true of retinoblastoma" means "what is factually/actually the case with retinoblastoma"

2. "accurately placed or thrown" - Not relevant here

3. "devoted to a cause or concept or truth" - Not the usage here

4. "expressing or given to expressing the truth" - Not quite right; we're not talking about the doctor expressing truth, but about a fact being true

5. "conforming to definitive criteria" - Not the main sense here

6. "worthy of being depended on" - Not relevant

7. "not pretended; sincerely felt or expressed" - Not relevant

8. "rightly so called" - Not quite right

9. "determined with reference to the earth's axis" - Not relevant

10. "having a legally established claim" - Not relevant

11. "in tune; accurate in pitch" - Not relevant

12. "accurately fitted; level" - Not relevant

The best sense is clearly sense 1: "consistent with fact or reality; not false" - because Dr. Knudson is saying that the principles discovered about retinoblastoma (that loss of both gene copies leads to cancer) would be true (factually correct) for all cancers.
