**Analyzing the Context of "Team"**

Okay, here's what I'm thinking. The text mentions a "scientific team" led by Webster Cavenee. My initial focus is on the word "team." Given my expertise, I immediately consider the possible senses of that word. The system presented two options, and it's quite obvious to me that the relevant sense here is "a cooperative unit" (sense 1). This is because the context specifically refers to scientists working together, which clearly aligns with the concept of a collaborative group engaged in a scientific endeavor, like a team in a laboratory setting, rather than a group of draft animals. No need to overthink that one.

**Analyzing the Usage of "Used"**

Okay, the target word is "used" in the phrase "The team used a battery of..." and my goal is to pinpoint the most accurate sense. I've got a list of potential senses to consider, let's see:

*   **use%2:34:01::** Ah, this one – "put into service; make work or employ for a particular purpose." This looks promising. It includes words like "utilize" and "apply," which seem relevant to a team working with tools.
*   **use%2:34:02::** This is about taking or consuming something regularly. Doesn't quite fit the context.
*   **use%2:34:00::** "Use up, consume fully." This isn't the meaning here either.
*   **use%2:41:14::** This is about exploiting something to one's advantage, which is not applicable.
*   **use%2:41:04::** "Avail oneself to," or "apply" a principle or practice. Close, but not quite the intended sense in this specific context.
*   **use%2:41:03::** This is the "used to" sense, which is irrelevant.

Looking at the sentence, "The team used a battery of the newly developed 'gene probes,'" it's clear the team is *employing* or *utilizing* the tools, "gene probes." The phrase "put into service" is also appropriate. Therefore, sense 1, "put into service; make work or employ for a particular purpose" is the best fit. I'm confident in selecting this interpretation.

**Analyzing the Nuance of "Battery"**

Okay, so the text used "battery" in the phrase "a battery of the newly developed 'gene probes.'" My initial thought, even before considering the dictionary definitions, is that it's *not* referring to an electrical power source or any of the more literal senses. It's almost certainly a figurative usage.

Let's dissect this. I have to look at the candidate senses to ensure I get this right, so let's rule them out one by one. Sense 1, a group of guns or missile launchers, is obviously wrong. Sense 2, the electricity producing device, that's not it either. Sense 4, the pitcher and catcher? No. Sense 5, the series of stamps for crushing ores? Nah, that's not it. Sense 6, the heavy fire of artillery? Nope. Sense 7, an assault with physical contact? Definitely not.

Ah, here we go. Sense 3, a *collection of related things intended for use together*, that fits perfectly. Examples given in the text include "took a battery of achievement tests," which is spot on. "Gene probes" are being used in a collection, a group, together, and it's describing the *set* of those probes, just as you might say "a battery of tests." It's definitely sense index 3.

**Analyzing the Usage of "Developed"**

Okay, so the target is "developed" in the phrase "newly developed gene probes." Immediately, my mind jumps to the context: "gene probes." I know those – they're tools, products, techniques created within the scientific or biotechnology sphere.

Now, let's consider the possible senses. I quickly run through the likely candidates, checking against my mental dictionary of word senses.

Sense 1: "make something new, such as a product or a mental or artistic creation." This feels promising. The examples, like "Her company developed a new kind of building material," and "They developed a new technique," resonate. A gene probe is precisely that – a biotechnological tool, a created product. "Newly developed gene probes" seems to be a perfect fit for this definition.

Sense 2, "work out," doesn’t seem quite right. We use 'work out' in the context of a theory.

Let's also eliminate sense 12. Although it refers to creating something new, it describes breeding/cultivation rather than synthesis/engineering. "He developed a new kind of apple" is about growing something, but a gene probe is engineered, not grown naturally.

Therefore, after a quick comparison, sense 1 is definitely the best fit.

**My Analysis of "Genetic" in Context**

Okay, the target word is "genetic," and the context is "snippets of *genetic* material that can track a gene's presence in a cell." My mind immediately jumps to the possible senses. Let's see... I've got a few candidates.

First, there's the straightforward, broad sense – essentially meaning "inheritable" or "hereditary." Then, I have to consider the more specific options. Candidate #2 looks promising: it's "of or relating to or produced by or being a gene." The synonyms like "genic" and "genetical" are helpful, and the examples, like "genetic code," resonate.

Candidate #3 is "pertaining to or referring to origin," which feels less direct in this case. Finally, there's Candidate #4, "of or relating to the science of genetics" – while relevant, it seems a little too broad for the phrase.

Now, focusing on "snippets of *genetic* material"... "genetic material" *clearly* implies material that is composed of or pertains to genes – DNA, essentially. Thinking about it, it is a very concrete definition, not a metaphor.

So, when I consider the options, the meaning defined in sense 2 ("of or relating to or produced by or being a gene") fits perfectly. The phrase "genetic material" is material *relating to* genes, *being* genes, or *produced by* genes. It's the most precise and appropriate fit, with supporting examples like "genetic code" solidifying the association. I'm confident that sense 2 is the correct interpretation.

**My Analysis of "Material" in a Biological Context**

Okay, the target word is "material," and the context is *"...snippets of genetic material that can track a gene's presence in a cell."* My brain immediately jumps to the various senses of "material," and I'm quickly sorting through them to find the best fit. I've got to make sure I'm precise here.

First up, sense 1: *material%1:27:00:: - the tangible substance that goes into the makeup of a physical object.* Hmmm, that's promising. This seems to align with the idea of DNA, RNA, or whatever form the genetic information takes. It's *stuff* – the physical building blocks.

Next, I'm considering sense 2: *material%1:10:00:: - information (data or ideas or observations) that can be used or reworked into a finished form.* Could work, but it feels less direct. While DNA *contains* information, the phrase "genetic material" focuses on its physical substance, not the data it carries. It's almost too abstract.

Sense 3: *material%1:06:00:: - artifact made by weaving or felting or knitting or crocheting natural or synthetic fibers (fabric, cloth, textile).* That's obviously incorrect. Definitely not talking about fabric here. That’s an easy one to dismiss.

Sense 4: *material%1:06:01:: - things needed for doing or making something.* This is getting closer to the essence of biology but still doesn’t quite click. This is more of a general sense of “stuff you need.” DNA is definitely *needed*, but it’s more fundamental than just "things needed".

Finally, sense 5: *material%1:18:00:: - a person judged suitable for admission or employment.* Now, that's just absurd in this context. Clearly, not a person.

So, after reviewing all the candidate senses, the choice is clear. Sense 1, the "tangible substance that goes into the makeup of a physical object," is the correct interpretation. "Genetic material" refers to the physical matter itself – DNA, RNA, the molecular components that are, in this case, tracking the gene's presence. That's the core of the phrase's meaning.

**Analyzing "Presence" in the Context of Genetic Material**

Okay, the target word is "presence", and the context is "snippets of genetic material that can track a gene's presence in a cell." My immediate task is to identify the most fitting sense of "presence" here. Let's run through the candidates.

I see several options, but most can be quickly discounted. Sense 2, the "immediate proximity of someone or something," is clearly off. And I can rule out the spiritual connotations of senses 3 and 4, the "invisible spiritual being" and the "impression that something is present," as well as the more abstract definitions like sense 5, "dignified manner or conduct," and sense 6, "the act of being present."

Now, sense 1, "the state of being present; current existence," is the most likely candidate. The example given, "he tested for the presence of radon," immediately clicks. It's about detecting or verifying that something exists in a given environment. "Track a gene's presence" functions in the same way, implying detection or identification of the gene's existence within the cell.

Sense 1 is the best fit.

My initial thought is pretty clear – this is almost certainly referring to a biological cell, the building block of life. The mention of "gene probes" and genetic material points directly in that direction.

Now, let's confirm this by running through the senses from my mental lexicon. I've got a few options: a small compartment, which is option 1. We also have, crucially, the biological definition, which is candidate 2. Then there's an electric cell (candidate 3), a "cadre" of people (candidate 4), mobile phone (candidate 5), a monastic cell (candidate 6), and a prison cell (candidate 7).

Scanning those, the biological sense, `cell%1:03:00::`, is the perfect fit. The context is perfectly aligned.

Alright, that settles it. I'm confident in assigning the index value of 2 to the word "cell" in this context. It's a textbook biological usage, and there's no ambiguity.

**My Analysis of "Analyzing" in Context**

Okay, so the target word is "analyzing," and the context is about work with cells extracted from eye tumors. My initial instinct is to run through the possible senses of the word. Let's see... I'm immediately thinking of a few potential meanings. There's the general "consider in detail" sense, like analyzing a poem or a complex case. Then there's the more scientific, "break down into components" sense, which seems more relevant here. We also have that sense related to financial analysis, and then there's the psychoanalytic meaning, which clearly doesn't apply here!

Given that we're dealing with "cells extracted from eye tumors," I'm leaning heavily towards the "break down into components" meaning. The text is describing a scientific investigation, where the team is likely using gene probes to look for defects. This fits perfectly with that second sense: breaking down a biological specimen – in this case, cells – to understand its essential features, or in this case, its genetic defects. The example "analyze a specimen" seals the deal for me. Sense 2 is definitely the most appropriate.

**Analyzing the Best Sense of "Extracted"**

Okay, so the target word is "extracted," and I need to figure out the best meaning in this context: "By analyzing cells extracted from eye tumors..." Let's see, eight candidate senses are listed. My initial thought is that it's about *removing* cells from tumors, but let's break this down systematically.

First, I need to look at the definitions. Sense 1 is: "remove, usually with some force or effort; also used in an abstract sense," with synonyms like "pull out, take out." Sense 6 is: "obtain from a substance, as by mechanical action," with synonyms like "press out, express." Sense 1 seems like a good starting point, as this sounds more like a physical removal process.

Okay, let me consider the core operation: Are we pulling cells out, like removing a weed or extracting a tooth? Or are we *expressing* something from the tumor, as in squeezing juice from fruit or oil from seeds? It feels like the context implies *removing* the cells, likely through a biopsy or similar method.

Now, checking the hypernyms helps solidify my choice. Sense 1's hypernym is "remove, take, take away, withdraw". Sense 6's hypernym is "separate". Sense 1 uses the synonyms "pull out, pull, pull up, take out, draw out". These synonyms and the definition "remove...with some force or effort" really resonate with the idea of taking a sample from a biological structure.

Considering this, I lean towards Sense 1. The tumor is the source, and cells are obtained from it, not 'expressed' from it. This suggests the application of force or effort, in the form of a biopsy or tissue removal. The other senses just don't seem like a fit. Therefore, I'm confident that Sense 1 ("remove, usually with some force or effort; also used in an abstract sense") is the correct interpretation.

**My Analysis of "Eye" in Context**

Okay, so I need to pinpoint the exact meaning of "eye" in this sentence: "By analyzing cells extracted from <t>eye</t> tumors, they found defects in the second copy of chromosome 13 in the exact area as in the first copy of the chromosome." Let's break this down systematically.

First, I need to consider the candidate senses provided. I have:

1.  "the organ of sight" – the classic meaning, the oculus.
2.  "good discernment" – could be metaphorical, relating to observation.
3.  "attention to what is seen" – similar to the above, focused observation.
4.  "an area that is approximately central within some larger region" – Hmm, this feels less likely, I'm already skeptical.
5.  "a small hole or loop (as in a needle)" – Definitely not this one.

Now, let's look at the context: "eye tumors". The phrase immediately suggests a medical context, specifically something like retinoblastoma, a disease I'm very familiar with and which is related to defects in chromosome 13. The connection is clear.

"Eye tumors" are tumors *of* the eye. They are occurring in the physical organ, the part associated with sight. Therefore, based on this phrase, "eye tumors" are of the organ of sight.

Given that, sense 1, "the organ of sight", is the only sensical fit. The other senses are completely incongruent, there's no way "good discernment," "attention," or the "central area" fits this context. The needle "eye" is a nonstarter. Sense 1 is the correct one.

**Analyzing the Semantics of "Found"**

Okay, so I'm looking at the word "found" in this sentence about chromosomal defects: "By analyzing cells extracted from eye tumors, they <t>found</t> defects in the second copy of chromosome 13..." My goal is to pinpoint the most accurate sense of "found" here. Let's break it down.

First, I quickly reviewed a few candidate senses from my mental lexicon. I have to consider: "come upon," "discover the existence of," "find something lost," "establish after study," and the general sense of "making a discovery." Right away, the "come upon" and "find something lost" senses seem irrelevant.

Then I considered Sense 2 ("discover or determine the existence, presence, or fact of") versus Sense 4 ("establish after a calculation, investigation, experiment, survey, or study"). I'm drawn to Sense 2, thinking about words like "detect," "observe," "discover," "notice" as synonyms. The example of "We found traces of lead in the paint" really clicks for me as a parallel structure and meaning to "they found defects in the second copy of chromosome 13."

I paused to check the structure of Sense 4. I was second-guessing myself; does "establish after study" take a direct object, or does it take a proposition or a value? I quickly reviewed the WordNet examples. The key question I was asking: is this about finding a *fact* or about the act of *perceiving*? The example "The physicist who found the elusive particle won the Nobel Prize" seemed to fit both, but I needed to be precise.

I went back to WordNet to double-check. I drilled into find%2:39:02::, which aligns with my Sense 2. It's a hypernym of "perceive." The definition reinforces my initial thought: "discover or determine the existence, presence, or fact of." The provided synonyms (detect, observe, discover, notice) felt very appropriate.

I then went to look at find%2:32:00:: which would correspond to sense 4 from my initial review. The hypernym there is "determine". It's all about establishing something through calculation, experimentation, etc. And I re-read the examples, which had me re-evaluating, specifically "The physicist who found the elusive particle won the Nobel Prize."

I checked the prompts, which lists that example under sense 4! But I am still thinking about sense 2: "discover or determine the existence, presence, or fact of".

I then asked myself, can defects be "detected" or "observed"? Absolutely, yes. "By analyzing cells... they *detected* defects". The semantic parallel of "detecting defects" to "finding traces of lead" is what clinched it. I'm confident now.

Finally, I carefully compared senses 2 and 4. Sense 2 is about perceiving, observing, and detecting the physical presence. Sense 4 is about establishing a fact through a process. In this context, with the use of "gene probes" and the analysis of cells, it's the direct *detection* or *observation* of a defect that's being described, not the *establishment* of a fact *about* the defect after an investigation. Therefore, the best fit is definitely Sense 2, the sense of "discover or determine the existence, presence, or fact of." The team is detecting the existence of a physical anomaly.

**Analyzing the Best Sense of "Defects"**

Okay, so I'm trying to figure out the best meaning of "defects" in this text about eye tumors and chromosome 13. My initial thought is that it's probably related to a biological issue, but I need to be precise. Let's see, I've got a few options:

1.  "an imperfection in a bodily system" - this sounds promising, but is a chromosome *part* of a bodily system, or is a defect *within* the chromosome an imperfection in a bodily system? It's a subtle distinction, and one that is important to get right.
2.  "a failing or deficiency" - This could work, it is quite general, and I am not a fan.
3.  "an imperfection in an object or machine" - Now, a chromosome *could* be thought of as a physical entity, an "object," but that feels like a stretch, or too generic.
4.  "a mark or flaw that spoils the appearance of something" - Again, seems less relevant to genetic material.

Right, back to sense 1. Let's dig deeper, as a more detailed analysis is important. My immediate thought is to check if WordNet has anything specific on *genetic* or *chromosomal* defects. I have to find a good sense for my context. Does WordNet include genetic or chromosomal defect under sense 1, "an imperfection in a bodily system"? Let's verify. This sense has examples like "visual defects" and "defects in the lungs." Does "genetic defect" fit into that category? What about "congenital defect," "birth defect," or "congenital disorder"? Let's make sure that WordNet's sense 1 does not exclude the usage that I am trying to use.

Okay, let's see. In WordNet, sense 1 is, again, "an imperfection in a bodily system" - and the examples seem to align, I see words such as: "congenital defect, birth defect, congenital disorder". Now, this looks more and more like the correct fit. Let's check the hypernyms of sense 1 - physiological condition, physiological state, and those seem relevant, especially given the biological context. Sense 1 also has hyponyms that are more specific, such as functional defects, organic defects, and ocular defects.

Wait, looking at "organic defect" -- a defect of bodily structure -- a chromosomal deletion would be a defect of bodily structure! That clinches it. A defect in chromosome 13 *is* a defect in the bodily structure and is clearly sense 1, "an imperfection in a bodily system".

Let's do a double check on sense 3, "an imperfection in an object or machine." A chromosome is *definitely* a biological entity, not a manufactured one. So, I am pretty certain that sense 1 is correct. A chromosome is biological/bodily and not a manufactured object or machine. This is absolutely the best fit, making the biological/medical sense ("an imperfection in a bodily system") the most accurate.

**Analyzing the Chromosome Data**

Okay, so I'm digging into this cell analysis from the eye tumors. The key here is this phrase "second copy of chromosome 13." My immediate instinct is to parse that, to make sure I'm on the right track. I've got two main senses for "second" popping into my head. One is the ordinal - the one that comes *after* the first. The other, less likely, is the one related to a subordinate part in a group or system, like a "second violin" in an orchestra.

Thinking about it in context, "second copy of chromosome 13" has to be that ordinal sense. It's referring to the *subsequent* copy, as opposed to the *initial* copy. It’s a comparison, and the first "copy" must exist for a "second copy" to be defined. That's the clear meaning we need here, contrasting it with the "first copy." So, sense 1 is definitely the correct one to apply.

**My Analysis of "Copy" in the Chromosome Context**

Okay, so the target word is "copy," and we're dealing with chromosome 13 here. My expert instinct immediately kicks in to consider the likely biological context. I need to figure out which sense of "copy" is most appropriate.

Let's look at the options. Sense 1, a transcript of a record, is a definite no-go – it doesn’t fit the biological framework at all. Sense 3, written matter, and Sense 4, journalistic material, are equally irrelevant to this situation involving chromosomes.

That leaves Sense 2: "a thing made to be similar or identical to another thing." The definition, specifically the example of a clone being a copy of its ancestor, makes the connection in biology. We're talking about something essentially *replicated*, an entity which, in this case, is a chromosome or gene that is similar or identical to another. Makes perfect sense. Therefore, Sense 2 is the clear winner here.

**Analyzing the Best Sense for "exact"**

Okay, so I need to pinpoint the most appropriate indexed sense of "exact" within this sentence: "By analyzing cells extracted from eye tumors, they found defects in the second copy of chromosome 13 in the <t>exact</t> area as in the first copy of the chromosome."

My initial candidates are:
1.  **exact%3:00:00::**: *marked by strict and particular and complete accordance with fact* (e.g., "an exact copy")
2.  **exact%5:00:00:correct:00**: *(of ideas, images, representations, expressions) characterized by perfect conformity to fact or truth; strictly correct* (e.g., "a precise measurement")

Right, let's dive into WordNet. I need to make sure I am fully evaluating each sense. Looking specifically at the first sense: **exact(a)** (marked by strict and particular and complete accordance with fact). Hmmm... I recall an example for sense one, "hit the exact center of the target."

A check confirms that the example sentence "hit the exact center of the target" is indeed in WordNet 3.0. Let's make sure I'm not mixing up WordNet versions.

Now, let's re-examine Sense 2: **accurate, exact, precise**. The definition is: *(of ideas, images, representations, expressions) characterized by perfect conformity to fact or truth.* I see the examples are: "a precise image", "a precise measurement".

Back to the context: "in the exact area as in the first copy of the chromosome." The key here is that "exact area" is referring to the *precise, identical* location or spot.

Considering the nuances:
*   Sense 1, *marked by strict and particular and complete accordance with fact*, aligns with the idea of a specific, identical area.
*   Sense 2 is really talking about the accuracy of *ideas, images, representations, or expressions*. The key here is that an "area" is not such a thing.

Therefore, the best fit is definitely **Sense 1 (exact%3:00:00::)**. This sense best captures the meaning of an *identical* or *particular* location, just like "hit the exact center of the target."

**Analyzing the Nuances of "First"**

Okay, so I'm looking at the word "first" in this context: "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." My initial instinct is to pin down the precise meaning. Clearly, it's not the "preceding all others" sense, nor any of the other more abstract definitions. My focus is on the contrast with "second copy."

I'm thinking this is clearly an instance of "first" as an ordinal number, right? Like the beginning unit in a series. Let me check the candidate senses to confirm:

1.  "Preceding all others in time or space or degree" - Nope, not applicable here.
2.  "Indicating the beginning unit in a series" (synonym: 1st) - This looks promising.
3.  "Serving to set in motion" - Nah.
4.  "Serving to begin" - No.
5.  "Ranking above all others" - Doesn't fit.
6.  "Highest in pitch or chief among parts" - Definitely not relevant.

I see a clear contrast between "first copy" and "second copy." They constitute an ordered set, a series. This screams "ordinal" to me.

WordNet's `first%5:00:00:ordinal:00` sense, with its "indicating the beginning unit in a series" definition and `1st` synonym, nails it. Also, comparing that sense to `first%3:00:00::`, it is quite obvious, with the examples.

So, yeah, it's sense 2. Case closed. The authors are using "first" in its ordinal sense to refer to the initial copy in a series, contrasting directly with "second". It's a straightforward application of ordinal numbering in a scientific context.

**Deciphering "Copy" in a Biological Context**

Alright, the target word is "copy," and it's in the context of chromosomes. My initial thought process involves a quick mental scan of potential senses. "Transcript" comes to mind first, as that's a common term for a reproduction of information. But, is it applicable here? Then, "copy" as a duplicate object leaps out, that's sense #2: “a thing made to be similar or identical to another thing”. That definition feels immediately correct. Then there's the distraction of the other senses, "written matter", and "material for a journalistic account". Nope, those aren't it.

In biology, "copy" almost always refers to a replica, a duplicate entity. Think about the way we discuss chromosome pairs or gene replication. The "copy" *is* the duplicate, the identical or nearly identical version. Therefore, sense #2, *the* thing made to be similar or identical to another thing", is the perfect fit. Case closed.

**Deconstructing the Meaning of "Finding"**

Alright, let's break this down. The target word is "finding," and the context is a groundbreaking discovery in medicine. My initial thought process is to consider the possible senses of "finding" within WordNet. I immediately pull up the candidate senses: the act of determining something, a legal decision, and then, crucially, "something that is found." This last one immediately resonates because it aligns with the medical context of a scientific discovery.

I'm initially tempted to consider "act" because research is part of the process, but the sentence "The finding riveted medicine" suggests something more concrete, a *result*. Is it an action, or is it an entity? Let me think... "It was the first time anyone had showed that..." This points towards the thing that was shown, the thing that was discovered, and that's the "something that is found" sense. I then started to think about where this sense is categorized in WordNet, but I realized that the sense key is already provided, so I should trust that sense. I realize I have a tendency to go off on tangents, so I need to maintain focus on the sense keys provided.

Okay, let's re-evaluate. It seems quite clear that "The finding riveted medicine" is not about the *act* of finding, but the discovery itself. It is a scientific result. The examples provided—"the findings in the gastrointestinal tract"—make this even more apparent. The "findings" are observations, conclusions, discoveries.

So, I'm confident that the correct sense of "finding" here is "something that is found". The discovery, the result, the fact. It’s a noun signifying the outcome of the research, not the research itself. It perfectly aligns with the context of a new discovery revolutionizing medical understanding.

**Analyzing the Context of "Medicine"**

Okay, the target word is "medicine" and the sentence is "The finding riveted medicine." Let's break this down systematically. I know the nuances here, so I'll consider the most likely senses and eliminate the implausible ones.

First, I need to look at the candidate senses. I see four possibilities: "medical specialty", "medication", "the medical profession" and "punishment". The context is key. "The finding riveted medicine." Now, which sense fits best? Let's rule out "medication" and "punishment" immediately; those don't make sense in this scenario. "Medical specialty" (Sense 1) is a possibility, referring to the branches of medical science, but "medical profession" (Sense 3), which represents the learned practice and the medical community as a whole, is a better fit. The finding didn't just rivet a specific branch, but the entire field. The idea of punishment, while a possible figurative interpretation, is clearly incorrect. The most logical interpretation is that the finding captured the attention of the medical field or profession. So, I'm confident that sense 3 is the correct one.

**Analyzing the Sense of "First"**

Okay, so I'm looking at 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." My goal here is to determine the correct sense of "first" in this context.

I'm presented with several candidate senses. Let's walk through them methodically:

*   **Sense 1 (`first%3:00:00::`)**: "preceding all others in time or space or degree". That immediately resonates. It seems like the most obvious fit, considering the phrase "first time." The example "the first day of spring" is particularly illustrative. It's about an event happening before any other event of its kind, the beginning of a series. I also note the antonym, "last," solidifying this temporal aspect.

*   **Sense 2 (`first%5:00:00:ordinal:00`)**: "indicating the beginning unit in a series," like "1st." It's tempting, given the word "first," but this implies a sequence or ranking, like "first place." This doesn't seem to capture the core meaning of the sentence. While related to time, it's more about position within a list or order, which doesn't quite fit "the first time."

*   **Senses 3, 4, and 6 (`first%5:00:02:opening:00`, `first%5:00:01:opening:00`, and `first%3:00:03::`)**: These senses, dealing with "opening," "beginning," or being "highest in pitch," are clearly irrelevant in this context. "Opening" is too broad and can only refer to the opening of something, but not necessarily the "first" time something has occurred.

*   **Sense 5 (`first%5:00:00:best:00`)**: "ranking above all others." This is about being the best or foremost. This is incorrect.

So, let's go back to Sense 1 and solidify my decision. "The first time anyone had shown..." definitely implies that this event happened before any similar event. "First" here means the initial instance or occurrence. I'm seeing it as a starting point. It's the first in a chronological series of demonstrations. The "the first time anyone had showed..." is absolutely a temporal expression.

To check this interpretation, I'm checking WordNet. I specifically look for how WordNet describes `first%3:00:00::`. Good, I see the definition aligns perfectly. The examples, such as "the first house on the right" and importantly, "the first time I saw Paris," seal the deal. WordNet's own example with "first time" confirms the temporal sense.

Therefore, unequivocally, **Sense 1: `first%3:00:00::` ("preceding all others in time or space or degree")** is the correct interpretation in this context.

**Analyzing the Semantic Ambiguity of "Time"**

Okay, so the target word is "time," and the context is crucial: "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." I need to determine the precise sense of "time" here. Let's see... the candidate senses offered are:

*   **time%1:11:00::** An instance or single occasion for some event. Right, something like "this *time* he succeeded."
*   **time%1:28:05::** A period of time as a resource. No, doesn't fit the context.
*   **time%1:28:00::** An indefinite period. Doesn't quite feel right, not what "the first time" refers to.
*   **time%1:28:06::** A suitable moment. Doesn't feel correct either.
*   **time%1:03:00::** The continuum of experience. Nope, not relevant here.
*   **time%1:11:01::** A person's experience on a particular occasion. Could fit, but the first one sounds better.
*   **time%1:28:03::** A reading of a point in time. Clearly not.
*   **time%1:28:04::** The fourth coordinate. Ridiculous.
*   **time%1:07:01::** Rhythm. Also irrelevant.
*   **time%1:28:01::** Prison term. No way.

Ah, "the first *time*." That's the key. That phrase signifies a specific occurrence, a single instance. Sense 1, "an instance or single occasion for some event," fits absolutely perfectly with the context of something happening for the first time. "This time he succeeded." The example clarifies my thinking perfectly. Therefore, sense 1 (index 1) is the winner.

**Analyzing the Semantic Nuances of "Showed"**

Okay, the target word is "showed," and my goal is to pinpoint the most accurate sense based on the context: "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." Immediately, I'm drawn to several possibilities, especially those related to demonstration and proving something. Let's see...

I'm considering these candidate senses: giving an exhibition, establishing validity, providing evidence, or simply making something visible. The key is in the specifics. Is it *just* visible, or is there a *demonstrable proof* at play?

Hold on... senses 2 and 3 are the closest: "establish the validity" and "provide evidence."  I need to tease apart the subtleties. Sense 2 includes phrases like "by an example, explanation or experiment," which is intriguing. The synonyms, like "prove, demonstrate, establish," are precisely what I'm looking for in terms of scientific rigor. I need to make the right interpretation.

Now, consider the sentence structure: "anyone had *showed* that..." The subject is "anyone," which implies an agent of some kind, and it seems this agent must be proving something.

Sense 3, "provide evidence," is usually associated with inanimate subjects: "The blood test showed...". But wait a moment, in Sense 2, an agent can be at the subject of the sentence, as in "the mathematician showed..." or "anyone had showed that..."

Okay, here's the connection: the agent, "anyone," is acting like a scientist, establishing the validity of a claim by experimenting and thus establishing it as true. This lines up perfectly with Sense 2: "establish the validity of something, as by an example, explanation or experiment." The experiment or explanation is the agent's work, which is why "anyone" can be the subject in the sentence.

Let's double-check: sense_key=show%2:31:00:: definition: establish the validity of something, as by an example, explanation or experiment. Yep, the synonyms - prove, demonstrate, establish - are precisely what this context needs.

In conclusion, "showed" in this context is best interpreted as the scientific act of *proving* or *demonstrating* something for the first time by experiment. Sense 2 is the most accurate fit.
