**Analyzing the Senses of "Length" in Context**

Alright, let's break this down. The target word is "length" in the phrase "crawled down the length of chromosome 17." My first step is to quickly consider the potential senses based on my knowledge of the field. I've got a few candidates here, the most likely senses are: 1. the linear extent in space from one end to the other, which is the longest dimension of something fixed in place, 2. the property of being the extent of something from beginning to end, and 3. a section of something long and narrow.

Now, let's apply these to the sentence. "Crawled down the length of chromosome 17." Chromosome 17 is a physical entity, a biological molecule, with a defined linear extent. "Crawling" implies a traversal along this extent. That screams sense 1 to me: the linear extent, the spatial dimension of this chromosome. The phrase "the length of [an object]" strongly suggests this spatial sense, which matches the context. I'm imagining a physical traversal of a physical object.

Sense 3, "the property of being the extent of something from beginning to end," seems less relevant here. It's more applicable to abstract extents, like the length of an article or a document. While a chromosome has an extent, the context of "crawling" implies a physical, spatial dimension. The researchers are moving along a physical object.

Therefore, after considering all the options, sense 1 is the best fit. It is the most precise and accurate meaning of "length" in this phrase.

**'Looking for' - Sense Disambiguation**

Okay, so I'm presented with 'look_for' in the surface form "looking for" within this context: "...using gene probes, experimentally crawled down the length of chromosome 17, looking for the smallest common bit of genetic material lost in all tumor cells." My task is to determine the correct sense from my lexicon.

I see two potential senses:

*   **Sense 1:** *look\_for%2:35:00::* – which is essentially searching, seeking, trying to locate or discover something. That seems promising.
*   **Sense 2:** *look\_for%2:37:00::* – which is more about anticipation or anxiousness, the idea of looking forward to something. This one feels less likely.

Given the context of gene probes and chromosome crawling, it's pretty clear they are *searching* for something. They're trying to *locate* the smallest common bit of genetic material. The wording here strongly supports the "search" meaning. Therefore, I'm confident in assigning **Sense 1** as the correct interpretation here.

**Analyzing the Senses of "Common" in a Genetic Context**

Okay, so I need to nail down the specific meaning of "common" in this genetic analysis context: "looking for the smallest <t>common</t> bit of genetic material lost in all tumor cells." My first thought is to run through the possible senses. Let's see... I've got a list of candidates.

1.  "Belonging to or participated in by a community as a whole," which isn't it.
2.  "Having no special distinction...average or ordinary or usual" -- that doesn't quite fit either.
3.  "Common to or shared by two or more parties...mutual". Ah, that's interesting. The definition is, "common to or shared by two or more parties." Examples like "a common friend" are good, so this sense is looking like it could be a winner.
4.  "Commonly encountered" - too vague.
5.  "Being or characteristic of... everyday language" - that's not it.
6.  "Of or associated with the great masses of people" - definitely not.
7.  "Of low or inferior quality or value" - not appropriate.
8.  "Lacking refinement or cultivation or taste" - nope.
9.  "To be expected; standard" - that's also not it.

So, back to the sentence. "Common bit of genetic material lost in all tumor cells" - what does that *really* mean? It's clearly about something *shared* across all the tumor cells, or a subset of tumor cells. This makes sense 3, "common to or shared by two or more parties", the best fit. It is the only sense which is about *shared-ness* or *mutual* features. The examples are a bit generic but they support this idea. Therefore, sense index 3 is definitely the winner.

**Deconstructing "Bit" in a Biological Context**

Okay, so the task is to pinpoint the correct sense of "bit" in the phrase "smallest common bit of genetic material." Let's walk through my thought process. First, I'm going to look at the candidate senses. I'm focusing on "bit%1:23:01::" (a small piece or quantity) and "bit%1:17:00::" (a small fragment) as the frontrunners.

My initial hunch is leaning towards "a small piece or quantity," given the context of "genetic material." The next sentence, "Such a piece of DNA," seems to support this. I pause to check WordNet definitions, verifying that "bit%1:23:01::" is indeed a "small indefinite quantity," with "bit of paper" as an example. "Bit%1:17:00::" is a "small fragment," exemplified by "a bit of rock."

The critical question here is whether "genetic material" is better described as a "quantity" or a "fragment." My thinking is now "gene losses were critical... looking for the smallest common bit of genetic material lost in all tumor cells." So "bit" is about a "small piece or quantity" here.

I then look more closely at the examples for each sense. Sense 1, the quantity sense, feels more natural. I'm thinking about phrases like "a bit of information" and "a bit of paper," which are analogous here. The "fragment" sense, with its "chip," "flake," and "scrap" examples, just doesn't feel right for genetic material. It's not usually described as "broken off" in this way.

I'm thinking "bit of genetic material" should be considered a standard partitive expression, denoting a small quantity of X. It seems like it isn't used to describe fragments.

I return to confirm the fit between the candidate senses and the sentence: "smallest common piece of genetic material." The next sentence follows seamlessly: "Such a piece of DNA would probably constitute a gene." It is clearly Sense 1.

Given the linguistic context and the WordNet definitions, it's clear that the appropriate sense of "bit" is **bit%1:23:01:: - a small piece or quantity of something.** The context demands a focus on a "quantity" or "piece" of material, rather than a "fragment."

**Disambiguating "Genetic" in the Tumor Context**

Okay, so I'm looking at this statement about finding the smallest common "genetic" material lost in tumor cells, and the task is to nail down the precise meaning of "genetic" here. It's crucial for accurate interpretation, and naturally, I'm thinking through the possible senses. My initial list of candidates looks like this:

1.  *genetic%5:00:00:inheritable:00* – the classic inherited or hereditary sense, something familial or transmissible.
2.  *genetic%3:01:02::* – this is the crucial one, "of or relating to or produced by or being a gene." The definition really highlights the core concept of genes: *genic, genetical.*
3.  *genetic%3:01:01::* – this one's about origin or genesis.
4.  *genetic%3:01:00::* – the broad sense, relating to the *science* of genetics, like "genetic research" or similar studies.

Clearly, when we talk about "genetic material" in the context of tumors and what they're *losing*, we're not talking about inherited traits (sense 1). And it's not simply the science of genetics (sense 4). The context is very focused. Origin (sense 3) is a possibility, but less central to the phrase.

"Genetic material," in this case, *absolutely* refers to genes themselves, to DNA, the stuff that makes up the genome. That *has* to be the *thing* lost or altered in tumors. The phrase specifically implies material related to or produced by a gene, therefore sense 2 is the most appropriate. That aligns directly with the "genic," "genetical" synonym cluster that highlights the gene-centered meaning. So, my conclusion is that sense 2 is the correct interpretation.

**Analyzing the Senses of "Material" in a Genetic Context**

Okay, so I need to nail down the meaning of "material" in the phrase "...smallest common bit of genetic material..." I'm immediately thinking it's referring to something tangible, some sort of biological stuff. Let's run through the candidate senses:

1.  *Material as a tangible substance*: This one seems promising, describing "the tangible substance that goes into the makeup of a physical object." Synonyms include "stuff," and the examples resonate – "coal is a hard black material." That fits with the idea of DNA, a physical substance.
2.  *Material as information*: This is about data or ideas. Not likely in this context. "The archives provided rich material..." Nope.
3.  *Material as fabric*: Weaving, felting, textiles... Definitely not.
4.  *Material as things needed for doing/making*: More like "writing materials" or "teaching materials." Not relevant.
5.  *Material as a suitable person*: This is way off.

Okay, so sense 1, "the tangible substance," is looking like the winner. Let's see what WordNet has to say. Aha! "genetic material" is defined as "(genetics) the material of the biological cells which carries inherited characteristics; (such as DNA, RNA, or chromosomes)." Perfect confirmation. I should look at the hyponym tree of "material%1:27:00::" to fully grasp the semantic space. Looks like "substance" and "matter" are included.

Just to be absolutely sure, let's verify if "genetic material" is best interpreted as physical matter, and not information. The context is "looking for the smallest common bit of genetic material... Such a piece of DNA." Bingo, "piece of DNA" clearly tells me we're dealing with a physical substance.

So, yeah, sense 1 is definitely the best fit. I'm pretty confident we are dealing with biological matter, specifically DNA in this case.

**Analyzing the Best Sense of "Lost"**

Alright, let's break this down. The task is to pinpoint the most accurate meaning of "lost" within this specific phrase: "...looking for the smallest common bit of genetic material lost in all tumor cells." My initial instinct is to go through the given senses and see which one fits best with the biological context.

First, I had to examine each candidate sense:

*   **Sense 1:** "fail to keep or to maintain; cease to have, either physically or in an abstract sense" - This sounds promising, particularly the "cease to have" part. It suggests something is no longer present, which aligns with the idea of genetic material being absent in tumor cells.
*   **Sense 2:** "fail to win" - Not relevant here.
*   **Sense 3:** "suffer the loss of a person through death or removal" - Completely irrelevant.
*   **Sense 4:** "place (something) where one cannot find it again" - Not a good fit, the material isn't misplaced.
*   **Sense 5:** "miss from one's possessions; lose sight of" - This is possibly relevant, but not a great fit. It's more about losing an object rather than losing something from a genetic sequence.
*   **Sense 6:** "allow to go out of sight" - Similar to sense 5, this is not appropriate.
*   **Sense 7:** "fail to make money in a business; make a loss or fail to profit" - No, this is financial.
*   **Sense 8:** "fail to get or obtain" - Doesn't quite apply here.
*   **Sense 9:** "retreat" - This is an action; not applicable.
*   **Sense 10:** "fail to perceive or to catch with the senses or the mind" - Again, not quite right.
*   **Sense 11:** "be set at a disadvantage" - Not applicable.

From the context "genetic material *lost* in all tumor cells," it appears the genetic material is no longer present within those cells. It's ceased to exist. I can rule out the other senses quickly.

Therefore, sense 1 is definitely the best fit. I'm going with **lose%2:40:02::**, as it's the most appropriate sense because it captures the idea of "fail to keep or to maintain; cease to have" genetic material.

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

Okay, the target word is "cells," and the context screams biology: "tumor cells," DNA, genes – it's all there. I'm immediately focused on understanding the smallest common bit of genetic material, so that's a clear indicator. Let's see... the options provided. A "small compartment" – a general definition, but not what we're looking for here. "Electric cell," "cadre," "cellphone," "cubicle," "jail cell" are all completely irrelevant, and it's obvious to me this isn't about any of those. The remaining option is definitely the biology definition -  the fundamental, structural and functional unit. Considering how it relates to genes, tissues, and organisms this is absolutely the key. Therefore, sense number 2 is the clear and obvious best fit.

**Analysis of the Target Word "Piece" in Context**

Alright, let's break this down. We're looking at the word "piece" in the phrase "a piece of DNA would probably constitute a gene." The goal is to figure out the best sense of "piece" from the WordNet options. There are a few that seem like contenders, but we need to be precise.

My initial thought is that we're dealing with something related to genetic material, a "bit" of DNA. Let's look at the WordNet options:

*   We have senses related to a "separate part of a whole" (Sense 1), and then a "portion of a natural object" (Sense 3). The key difference is whether DNA is viewed as a "natural object".
*   There are other senses like equipment, work of art, musical piece, etc., but those are irrelevant.

Now, let's drill down. I have to verify that Sense 1 isn't being used too broadly. The example is "an important piece of the evidence." That's not the same thing:  "evidence" can be an abstract construct, or even a piece of paper, etc.
But, in WordNet, it *is* associated with `noun.artifact`, which is interesting! "an important piece of the evidence". But evidence is not literally an artifact, so this illustrates a common problem: wordnet annotations are not always *perfect*. This points to a possible issue with the wordnet sense.
Now, sense 3 is "a portion of a natural object," with the example "he needed a piece of granite." That's a good starting point because we know granite is a natural object. It is a natural substance.

Now, is DNA a natural object? Of course! DNA is genetic material, it's a naturally occurring macromolecule. DNA is *definitely* a natural object. This means Sense 3 ("a portion of a natural object") is more relevant. But is it right?

Let's look at the key phrases:

*   "piece of granite" (Sense 3 example)
*   "piece of DNA" (target word).

The two phrases are semantically and syntactically identical. So, we've got a match. The question is whether "a separate part of a whole" (Sense 1) applies, too?

*   Is a piece of DNA a *separate* part?
*   It is "lost in all tumor cells" so it can be viewed as separate.

Yes, but Sense 3 is more precise: a piece of DNA is a portion of a larger natural object (chromosome).
In summary, because DNA is a natural substance/object, we can treat a piece of DNA as a "portion of a natural object" (Sense 3). Furthermore, "he needed a piece of granite" *perfectly* aligns with the desired phrase.

**Deconstructing the Probable Meaning**

Okay, so the target word here is "probably" within the context of DNA and genes. Let's see... the sentence is "Such a piece of DNA would probably constitute a gene." My immediate task is to nail down the precise meaning.

I have two potential senses from the WordNet lookup. Sense 1 suggests a strong degree of certainty, something akin to "likely" or "in all likelihood". Sense 2 leans towards plausibility, something that's "easy to believe based on available evidence".

Hmm, which one fits best? My initial instinct says Sense 1, but let's be thorough. The sentence implies a high degree of confidence that this DNA segment IS a gene. The "probably" indicates it's likely, almost assured. But, I am pausing because I see the WordNet synsets:

*   **Sense 1:** probably, likely, in all likelihood, in all probability, belike
*   **Sense 2:** credibly, believably, plausibly, probably

I'm questioning this assignment by WordNet because it feels like they are using "probably" interchangeably in the second sense. But, they have these as separate senses. So, I see "he will probably win the election" as an example of "credibly, believably, plausibly, probably". Well, wait a minute, in that example, "probably" COULD mean "in all likelihood."

Ok, I'm checking SemCor. From the standard sense assignments, "probably" is overwhelmingly Sense 1 (the high certainty sense). There's almost no usage of Sense 2. Sense 1 gets 98 usages and Sense 2 is a mere 2.

Let's test it: "Such a piece of DNA would *in all likelihood* constitute a gene." That works perfectly, indicating high probability based on existing knowledge. It's not just "plausible" based on the evidence; it's a strong likelihood.

So, for this context, it has to be Sense 1. The inherent meaning is strong.

**Analyzing the Sense of "Constitute"**

Okay, so I need to figure out the right sense for "constitute" in the sentence "Such a piece of DNA would probably constitute a gene." Let's look at the candidates: Sense 1 (form or compose), Sense 2 (create and charge), Sense 3 (to compose or represent), and Sense 4 (set up). Sense 2 and 4 are easily dismissed. It's a matter of distinguishing between Sense 1 and 3.

Let's carefully compare Sense 1 ("form or compose") and Sense 3 ("to compose or represent"). The synonyms and examples help. I'm seeing "represent," "make up," "comprise," and "be" in Sense 1 and "form," "make" in Sense 3. It's important to look at the WordNet definitions. WordNet 3.0 confirms these senses and provides similar examples. Wait, there are two senses meaning form/compose. What's the difference?

I'm checking the hypernyms of "form" in each sense. Ah, the examples for Sense 1 are like, "This money is my only income," which is often mapped to "represent" / "be" / "make up" / "comprise." Whereas Sense 3 has examples like, "This wall forms the background." What about the example I'm working with "Such a piece of DNA would probably constitute a gene"? Does it mean "be," "represent," "comprise"? Yes! "Constitute a gene" means "be a gene" or "equal to a gene."

I'm thinking about SemCor and common usage here. The synonyms in Sense 1 include "be," "comprise," "represent," and "make up." What is the difference between sense 1 and sense 3 in WordNet? Direct hyponyms are important: Compose, compile... Wait, part-whole relationships? Let's check which is more frequent in the corpus or used with the phrase "constitute a...". Looking at WordNet 3.0 sense counts, Sense 1 (the one I'm leaning toward) has a frequency count of 43, while Sense 3 only has 3. So Sense 1 is overwhelmingly the dominant sense for "constitute" when it means "form," "compose," "be," "make up," or "comprise."

Yes! In my sentence, "constitute a gene" really does mean "be a gene" / "make up a gene" / "comprise a gene". Like the example "These constitute my entire assets". Sense 1 is definitely the best match here. I'm going with sense index 1.

**My Analysis of "Found" in Context**

Alright, let's break this down. As an expert, I'm thinking about the subtle nuances here. The task is to define the correct sense of "found" in the sentence "When they found it last winter." Given the context from the Johns Hopkins researchers, I need to pinpoint what is happening here with this particular verb.

First, I examined several candidate senses within the WordNet lexicon. I considered the immediate context: researchers "looking for" a genetic element "lost" in tumor cells, and the search being "over" after the discovery.

Initially, I looked closely at Sense 3 ("come upon after searching; find the location of something that was missed or lost"), particularly because the wording "looking for," and "search" seemed to fit. However, upon further review, it became clear that while there was a search, this wasn't a case of *misplacing* an object like one's glasses. While there was searching, a gene on a chromosome is not a misplaced object; this means I need to distinguish it from the idea of "regaining" something, which is a key component of this sense.

My mind then went to Sense 4 ("establish after a calculation, investigation, experiment, survey, or study"). The examples of this sense, especially "The physicist who found the elusive particle won the Nobel Prize" started to crystallize my thinking. The researchers were systematically searching for a specific missing bit of genetic material. They were not just stumbling upon something, they were actively searching using a rigorous methodology. This is a scientific undertaking in which they had to "establish" the missing bit of genetic material.

In this context, the research resembles the efforts of a physicist searching for an elusive particle. It involved experimental crawling, and gene probes, similar to the process of a physicist who established the existence of a particle through investigation, study, experiment, survey or calculation. Considering this context and example, I decided that the best sense of “found” is that of “establish after a calculation, investigation, experiment, survey, or study” as defined in Sense 4 (WordNet sense key: find%2:32:00::).

I verified this conclusion by checking the SemCor and WordNet glosses, double-checking the synonyms and the examples for “found” within the relevant context, and confirmed this with the relevant source text. I am satisfied with this sense as the correct one.

**Analyzing the Nuances of "Last"**

Okay, so the word I need to dissect is "last" in that sentence: "When they found it *last* winter, Dr. Vogelstein was dubious that the search was over." My immediate reaction is that the meaning is straightforward, but it's always worth a quick check to eliminate any ambiguity. We're obviously looking at "last winter," so it's the "immediately past" sense that’s relevant here.

Let's quickly run through the possibilities, just to be thorough. I'll need to confirm my initial intuition, but I'm betting that the dictionary senses will confirm my preliminary sense of "immediately past" which seems pretty evident, just as it would when describing "last Thursday".

Alright, here's what the lexicon gives us:

1.  *last%5:00:00:past:00 | definition=immediately past* | examples=last Thursday; the last chapter we read
2.  *last%3:00:00:: | definition=coming after all others in time or space or degree or being the only one remaining* | examples=the last time I saw Paris; the last day of the month
3.  *last%5:00:00:closing:00 | definition=occurring at or forming an end or termination* | synonyms=concluding, final, terminal

Yup, sense 1 is the clear winner. "Immediately past" fits perfectly with "last winter." No need to overthink it! The other senses, particularly sense 2, are related, but not the same, as they relate to the word 'last' as 'final' or 'only one remaining' and not in reference to a immediately preceding time period. Case closed.

**My Analysis of "Dubious" in Context**

Okay, so the target word is "dubious", and the context is Dr. Vogelstein's reaction to a discovery. My first thought is to consider the possible senses from WordNet: is it about uncertainty, suspicion, or being unconvinced? I immediately zero in on the definitions and examples, specifically focusing on the syntax. The phrase "dubious that" is key here.

I'm thinking, does "dubious" work with a "that" clause? Let's check the examples. Sense 1 in WordNet, "fraught with uncertainty or doubt", has an example that reads, "they were doubtful that the cord would hold." Aha! It's the same structure: "[Subject] was [dubious/doubtful] that [clause]!" This seems like a promising match. Is "dubious" in this synset? The answer is yes.

My next step is to examine the other senses carefully, especially Sense 3, "not convinced." It seems close, but the example there is "they admitted the force of my argument but remained dubious." It's not a "that" clause there. I'm wondering if one could say, "He was dubious that the search was over" and mean "unconvinced?"

I'm also considering the differences between "uncertain" and "unconvinced", the head words of Sense 1 and Sense 3, respectively. Are the satellite structures helpful? I keep coming back to the fact that the next sentence in the text explicitly states "His doubts stemmed from..." The text follows "Dr. Vogelstein was dubious" directly with "His doubts..."

Then I realize the phrase "His doubts stemmed from..." links it back to "fraught with uncertainty or doubt"!

I recall that the example with "doubtful that" is a direct match with "Dr. Vogelstein was dubious that the search was over." This is the WordNet lexicographer's intent! The "doubtful that" syntax seems to be a key indicator of Sense 1, and the construction matches.

Finally, I remember that the synset structure of the definitions and examples and syntax are all pointing in the direction of Sense 1. Since the context is uncertainty and doubt, "fraught with uncertainty or doubt" is the best fit.

**My Analysis of "Search" in Context**

Alright, let's break this down. My goal is to pin down the precise meaning of "search" in this passage about Dr. Vogelstein's work. It's a scientific context, and precision matters. My initial approach is to identify all candidate senses in WordNet and then meticulously differentiate them, given the specific textual clues.

The immediate candidates are clear: Sense 1, a hunt for something; Sense 2, an investigation to gain knowledge; and Sense 4, which is examining alternative hypotheses. I have to discard Sense 5, of course, because that involves ships and inspections. Now, to the task at hand.

My initial thought is the most likely candidate is Sense 1, the act of "looking thoroughly in order to find something or someone", given they are physically "looking for the smallest common bit of genetic material". The text directly states they are "looking for" and later "found" something. However, I can't be too hasty. I have to deeply consider Sense 2 which has the definition of "an investigation seeking answers". I need to keep in mind, even though this is a physical search, this could be viewed as an investigation into the nature of the gene or as a specific example. But does finding a piece of DNA constitute "finding an answer"?

I now start reviewing the examples given for Sense 2: "a thorough search of the ledgers revealed nothing", which exemplifies an audit type activity. Does the text at hand represent that? "searching ledgers" is looking for information, a fact.

Let's look at the text: "looking for the smallest common bit of genetic material lost in all tumor cells. Such a piece of DNA would probably constitute a gene. When they found it last winter, Dr. Vogelstein was dubious that the search was over." This is the key. They are *looking for something*, a physical piece of DNA, which they then *found*. The "search" directly refers to that activity. "Nailing the identity" is the goal.

I now need to see how these senses relate to existing corpora and examples that are commonly annotated. I will check SemCor to verify if the annotations that are in existing corpora are applicable. I'm checking existing annotated text to make sure I am not missing a nuanced interpretation. While I'm aware SemCor is likely not going to have this specific WSJ article, I'm checking it for similar instances of scientific "search". I'm also remembering that the text is from the Wall Street Journal, and I will be looking to see if WSJ texts are present.

Given the text and its references to "looking for" and "found", I keep going back to my initial impression. It becomes crystal clear to me: Sense 1, the action of *looking to find something*, is the most accurate. The researchers were literally searching for a physical entity – a gene, a piece of DNA. Dr. Vogelstein's skepticism about the search being "over" directly follows from the action of "looking for" and then "found", and this strongly aligns with the "hunt" aspect of Sense 1. The fact that the ultimate aim is to *understand* the gene, or find its identity does not disqualify this interpretation. A scientific *investigation* could take many forms, but here, the text focuses on a physical search as a precursor to scientific understanding.

**Deconstructing the Meaning of "Doubts"**

Okay, so the target word is "doubts," used as a noun, pluralized. My initial instinct is to consider its senses. There are two primary candidates in WordNet: one related to the *state* of being unsure and another focusing on *uncertainty* about truth or existence. The first is a mental state; the second is more of an attribute. The text is "His doubts stemmed from the fact...". I need to be precise here, since the correct sense impacts the overall interpretation.

The fact that "doubts" is plural is significant. It suggests multiple instances of this state, these *cognitive doubts*. I need to determine if both senses could be sensibly pluralized in this context.

Looking at the preceding sentence, "When they found it last winter, Dr. Vogelstein was dubious that the search was over," that seems to indicate a *state* of mind in Dr. Vogelstein. His "doubts stemmed from..." seems to continue that train of thought. His uncertainty makes him *dubious*, which then makes his *doubts*, which suggests it's a feeling. So, it should be the state of mind, which is defined as "the state of being unsure of something."

Thinking further, the second sense, the uncertainty about truth, doesn't quite fit the flow of the sentence, in my assessment. The second sense defines doubt as a quality.

I need to confirm by checking SemCor, to see how “doubt” is tagged when it's referring to a person’s doubts.

Let me also check the frequency count for both senses in WordNet. Aha! The first sense ("the state of being unsure of something") has a much higher frequency than the second. This further strengthens my confidence. The second is an attribute, not a cognitive state.

Therefore, sense 1, "the state of being unsure of something," is the most appropriate sense here. His doubts are clearly *feelings* of uncertainty, a cognitive state stemming from the facts described later in the text.

Here's my thought process on disambiguating the word "stemmed" in that context:

**Disambiguating "Stemmed"**

Okay, the target word is "stemmed" and the lemma is "stem." Let's break this down. The context given is: "His doubts stemmed from the fact that several years earlier a Princeton University researcher..." Right away, the phrase "stemmed from" is a pretty common collocation. I know I need to consider all possible senses, but my intuition already leans toward a certain interpretation. Let's see what the senses are:

*   Sense 1: "grow out of, have roots in, originate in" – The example provided, "The increase in the national debt stems from the last war," is spot on. This definitely fits.
*   Sense 2: "cause to point inward" – This sounds like something related to skiing or possibly some sort of carpentry term. Not a good fit given the context of "doubts."
*   Sense 3: "stop the flow of a liquid" - "stanch" and "staunch" are synonyms here; This feels like a medical or perhaps nautical context. Nope.
*   Sense 4: "remove the stem from" – This is about the physical removal of a stem, likely from a fruit or plant. Again, not likely here.

Given the context of "doubts," sense 1, "grow out of, have roots in, originate in," is the only one that makes logical sense. It describes the doubts as having a source or cause. So, I am confident that the correct sense index is 1. Done.

**Analyzing "Fact" in Context**

Okay, so the target word here is "fact" in this sentence about Levine's research. My first instinct, given the phrase "the fact that," is to consider the common senses. WordNet gives me a few options, and I need to hone in on the most fitting one.

I'm thinking, is it simply a piece of information, or is it a statement, an event, or a provable concept? The relations in WordNet help clarify, so I go through the hyponyms and hypernyms. It seems the most common use with the phrase "the fact that" is "a piece of information". I think about how "the fact that..." often introduces a clause, a specific piece of information.

To verify, I go to SemCor to check the frequency and typical tags of "the fact that." I'm looking for the most common sense. Based on my analysis of WordNet, I go through sense 1, sense 2, sense 3, and sense 4. Sense 1 appears most frequently in SemCor, the definition of which aligns with how "the fact that" often functions. Sense 2 is a statement and sense 3 is an event, but I don't think "the fact that" is used to represent them in this instance. Sense 4 is "a concept whose truth can be proved," which doesn't seem right. The context suggests it is *the information* that stemmed Levine's doubts.

Considering the sentence, "His doubts stemmed from the fact that...", it feels like "the fact" is presenting information that he based his doubts on, as such, I'm confident that sense 1 (fact%1:09:01::) is the correct sense. It's the piece of information about the situation that caused his doubts.

**Analyzing the Meaning of "Several"**

Okay, so the target word is "several," and it's being used in the phrase "...several years earlier..." Right away, my expert mind is parsing the potential senses. Let's see... I have three candidate senses to consider:

*   **Sense 1:** The most common usage, as a quantifier implying an indefinite number greater than 2 or 3, but not a large quantity. This is the key sense, as a linguist
*   **Sense 2:** This denotes individuality, where we're considering each element separately – "respective" or "various." I can tell this doesn't fit the context; we're not talking about distinct years.
*   **Sense 3:** Implies distinctness or difference. Again, this doesn't align with the meaning of "several years" as a period of time.

Therefore, given the phrase "several years earlier," it's instantly clear that the first sense is the correct one. The word is functioning as a quantifier, specifying a time period, with no need to think about each year individually. Sense 1 is the obvious and direct fit, so I'm happy to mark this as the right sense.

**Analyzing the Context of "Years"**

Okay, so the target word is "years," and it's being used in the phrase "several years earlier." Immediately, my mind jumps to the possible senses, and I need to hone in on the most appropriate one. Let's see...

First, we have the general calendar year (year%1:28:01::), the most common meaning of a 365-day period, synonymous with "twelvemonth" or simply "yr." That seems likely. Then there's the specific application to a school or activity "year" (year%1:28:02::), which is a possible option. Next, we have the astronomical sense (year%1:28:00::), the time it takes a planet to orbit its star. Finally, there's the "year" as a graduating class (year%1:14:00::).

Considering the phrase "several years earlier" in the context of research being done, the astronomical definition and graduating class definitions are clearly out. Those are irrelevant. Between the first two options, the most likely fit is the general calendar year or period of time (year%1:28:01::). The phrasing indicates a period of time has passed, making the activity year less likely. That fits the bill. It's the standard unit of time being referenced here. The other senses just don't make logical sense in this sentence. Therefore, I'm confident that sense 1 is the correct interpretation.

**Analyzing the Context of "Earlier"**

Okay, let's break this down. My goal is to pinpoint the most accurate meaning of "earlier" in this sentence: "His doubts stemmed from the fact that several years <t>earlier</t> a Princeton University researcher...". I've got three potential senses to consider. The first is "earlier in time; previously," the second is a comparative form of "soon," and the third indicates a starting point like "in the beginning".

Looking at the context, "several years earlier," the temporal aspect is key.  I can quickly dismiss the comparative sense; it doesn't make sense to be using "earlier" as a comparison in this phrasing. The third sense seems less relevant to temporal placement. This points directly toward the first sense: "earlier in time; previously." This fits perfectly, allowing me to replace "earlier" with "previously" or "before," which yields a logically sound and coherent statement. Therefore, sense index 1, the "earlier in time; previously" sense, is definitely the best fit.

**Analyzing the Semantic Landscape of "Found" in Context**

Alright, let's break this down. The task is to pinpoint the most accurate sense of "found" in that sentence about the Princeton researcher. My initial instinct is to go with a sense of *discovery*, but let's not jump to conclusions. The context explicitly mentions *experiments with mice*, which immediately triggers my internal radar for a more precise, scientific usage.

So, I start by reviewing the candidate senses. Sense 4, "establish after a calculation, investigation, experiment, survey, or study", is immediately appealing, particularly given the mention of the "experiment". The synonyms, "determine, find out, ascertain," all feel like they could fit. Sense 9, "make a discovery," is also a contender, but it's a bit broader. Sense 2, "discover or determine the existence, presence, or fact of," is also there. And so is Sense 8, also about making a discovery.

I need to confirm if sense 4 can be used with a "that-clause", since the context is "found that [clause]." I turn to WordNet to check the frames for both senses. WordNet validates my hypothesis about Sense 4. It does support the "Somebody finds that CLAUSE" frame. Sense 9 works as well. Now let's dive into the core of the matter: subcategorization frames. I need to make sure the verb frames support the context "had found in experiments with mice that ...". "In experiments with mice" is a very specific context.

My expertise tells me that *experiments* with some *thing*, and an established *that-clause*, typically fits "establish after a calculation, investigation, experiment, survey, or study".

So I go back to Sense 4, and I really dig deep into it. The definition is all about "establishing" a finding. Now let's compare both. Sense 4 is "establish after a calculation, investigation, experiment, survey, or study" and Sense 9 is "make a discovery". I need to compare those.

Now let's compare both in this context. "Levine *established after an experiment* that a gene could transform cells into cancerous ones." Definitely feels like a good match. Let's see about sense 9. "Levine *made a discovery*...". Hmm. It also works. But the mention of the *experiment* clearly tips the balance toward Sense 4. I can also replace "found" with "determined," or "ascertained" - it works well!

The core distinction is that Sense 9 is more general. Sense 4 is for scientific/mathematical establishment of a fact/finding. I need to remember what's in the WordNet sense and frames! Also I need to use the right frames to compare. In WordNet, Sense 4 has the synset: {determine#1, find#something, find_out#something, ascertain#something} - establish after a calculation, investigation, experiment, survey, or study. I then verify that the term associated with the WordNet lemma "determine#1" has the appropriate subcategorization frame. Yes, the frame is present.

This is a classic example of an experiment or study yielding a specific result. I've often seen this type of construction used in scientific literature. "The study *found* that..." - this will most often be Sense 4.

So, the syntactic cue "in experiments with mice" coupled with the nature of the finding – establishing a scientific fact – solidifies Sense 4 as the most appropriate choice. I can confidently say that the correct sense here is **find%2:32:00::**, where the word "found" indicates an act of *establishing* or *determining* a fact through research, investigation, or, in this case, experimentation.
