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

Okay, so the target word is "length," and the context is this Johns Hopkins research involving chromosome 17. My initial task is to identify the correct sense of "length" from a given list of definitions. Let's see... the sentence is "For months the Johns Hopkins researchers, using gene probes, experimentally crawled down the length of chromosome 17..."

Right away, I'm thinking about the chromosome as a physical entity. The phrase "crawled down the length of" implies movement along something.

Looking at the candidate senses, I have to quickly determine which one best fits this idea of traversing something spatially. Sense 1, "the linear extent in space from one end to the other," jumps out as a strong possibility. That definition aligns well with the concept of a chromosome having a defined start and end. I imagine them "crawling" along that linear path.

Sense 4, "the property of being the extent of something from beginning to end," is similar, but I think sense 1 is more specific.

I consider the examples given, such as "the length of the table was 5 feet". I know the length of the table is linear extent in space and "crawled down the length of the river" also supports that notion.

Now, let's explore other possibilities. Could it be sense 2, "a section of something that is long and narrow," as in "a length of timber"? No, that doesn't really work here. It's "the length," not "a length". It's not a segment of the chromosome they're crawling down; it's the entire thing.

Okay, let's go back to sense 1 and test it. "The linear extent in space from one end to the other" ... "crawled down the length of chromosome 17". Yeah, that perfectly describes moving from one end of the chromosome to the other.

Therefore, the best fit is definitely sense 1. "Linear extent in space from one end to the other" is the key to understanding the meaning of "length" here. It's all about traversing a physical dimension.

**Analyzing the Nuances of "Looking For"**

Okay, so the prompt gives me "looking for" as the target phrase, and the context involves researchers painstakingly examining chromosome 17. The goal here is to identify the most accurate meaning of "looking for" in this specific scenario. My initial step is to break down the potential senses.

I've got two clear candidates: the first suggests an active *search* – trying to *locate* or *discover* something. The second points towards anticipation or excitement. Given my expertise, it's pretty apparent what the researchers are up to. They're not simply *anxiously anticipating* the genetic material; they are undertaking a meticulous *search* in an effort to *find* it. This isn't about an excited hope but a methodical effort.

Therefore, sense 1, the action of searching for, seeking, and trying to locate, is undeniably the most appropriate interpretation of "looking for" in this context. It's a precise act of investigation, not a feeling. I'm satisfied with this analysis.

**Analyzing the Meaning of "Common" in a Biological Context**

Okay, so the target word is "common," and the phrase is "...looking for the smallest common bit of genetic material lost in all tumor cells." My immediate thought is, what are the nuances here? Given my expertise, I quickly recognize that "common" isn't just about something being ordinary or widely known. It's about shared characteristics, particularly in this biological context.

I run through the likely senses – a quick scan shows several candidates. Sense 1, "having no special distinction," doesn’t quite fit. Neither does Sense 2, "inferior quality." Sense 3, "public," is irrelevant. Sense 4, "to be expected; standard" seems a bit too generic. The genetic material is not just ordinary but something it is shared. Sense 6 and 7, "unrefined" and "lowborn," are definitely off-base. Sense 8, "commonly encountered," is close, but there's a degree of repetition required here. Sense 9, "everyday language," is also not the right fit.

Ah, here it is: Sense 5, "common to or shared by two or more parties." That clicks. The genetic material is "lost in *all* tumor cells," meaning it's shared *by* them. It's *mutual*. That's the core meaning I need.

Just to be absolutely sure, I mentally review other examples of Sense 5. "Common friend," "mutual interests" – yes, that hits the spot. This genetic material is common *among* the cells, something they share. That is, it's mutual.

Alright, the best and most accurate fit is indeed Sense 5, "common to or shared by two or more parties." That seems pretty clear to me.

**Deconstructing the Meaning of "Bit" in a Genetic Context**

Okay, so I'm presented with "bit" and I need to figure out the best definition given the context of looking for the smallest common... thing... lost in all tumor cells. The context immediately steers me toward the idea of a *piece* of genetic material. That's my initial intuition, but I need to make sure I'm precise.

I went through the senses provided. It's not a "piece of metal for a horse," obviously. Not "food" or a "binary digit." A "drill part" is out, too. Is it a "key part?" Maybe... but not directly. The phrase that stands out is "bit of genetic material," which seems to be a piece or a quantity.

Initially, I considered Sense 1 ("an instance of some kind") and Sense 8 ("a small fragment broken off"), but then I honed in on Sense 6: "a small piece or quantity of something." The examples are perfect: "a spot of tea," "a bit of paper." That's what I'm looking for - a small component, a discrete *amount* of DNA.

I went through other synonyms, such as "piece," but the exact phrase is "a bit of genetic material". It's a small piece or quantity, not necessarily a fragment that's broken off. The crucial clue is that "such a *piece* of DNA" constitutes a gene, which directly reinforces the "small piece" concept.

I checked WordNet 3.0 to be thorough. The definitions in WordNet are very aligned with the sense I am using to interpret "bit". The definition that seems best to me is: "a small piece or quantity of something." The examples reinforce this: "a spot of tea," "a bit of paper," and "a bit of lint".

So, after careful consideration of all the possible meanings and the context, I'm confident that Sense 6 is the best fit. I'm going with "a small piece or quantity of something." It's definitely not a chip or fragment. The text indicates such "a piece of DNA would constitute a gene" that indicates the appropriate sense of *bit* in the context.

**Analyzing the Meaning of "Genetic"**

Okay, the target word is "genetic," specifically in relation to the smallest common bit of *genetic material* lost in tumor cells. Let's break this down. Contextually, "genetic material" *must* be about genes, DNA, the whole shebang. So, I need to pinpoint the right sense of "genetic" here.

First, I see a few candidates. There's sense 1, "of or relating to or produced by or being a gene," with synonyms like "genic" and "genetical." Seems promising. Then, sense 2: "pertaining to or referring to origin" – that's a bit broad, probably not. Sense 3 is about the *science* of genetics, and sense 4 is about inheritance. Hmm. "Genetic material" definitely isn't about the *science* of it, or necessarily about *inheritance* in this context.

Now, let's go back and carefully look at sense 1: "genic combinations; genetic code." *That's it*. "Genetic material" *is* about genes, and it's certainly related to "genetic code" and "genic combinations." This clearly covers the domain of "genetic material." This "of or relating to or produced by or being a gene" captures it perfectly. Sense 3, "of or relating to the science of genetics" is not relevant here.

Therefore, sense 1 is definitely the best fit. I'm going with that.

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

Okay, the target is "material," and the surface form is just "material," which seems straightforward enough. The context, however, is key: "...looking for the smallest common bit of genetic material lost in all tumor cells. Such a piece of DNA would probably constitute a gene." Right away, my mind runs through the potential senses. I've got:

1.  Information – data, ideas.
2.  The tangible substance that makes up a physical object – essentially, "stuff."
3.  An artifact made by weaving (unlikely here).
4.  A person judged suitable (absolutely not!).
5.  Things needed for doing or making something.

"Genetic material," that's DNA, and DNA is a molecule. It's a physical thing, a chemical substance. So, sense 2, "tangible substance," seems like the most obvious fit. DNA fits right into that. Hmm...but, wait. Could it be sense 1, "information"? DNA *does* carry information.

Let's do a quick double-check. Is there a specific sense of "genetic material" defined somewhere? Probably not. It's probably just using "material" as a head. The dictionary entries for other usages like "coal is a hard black material; wheat is the stuff they use to make bread" make the usage very clear. DNA is the material that constitutes genes and chromosomes.

Alright, let's play this out a little more. If we consider "material" to mean substance, then "genetic material" is referring to that tangible substance – DNA or RNA.

Let's eliminate the irrelevant ones first. Sense 1, information, is tempting. DNA certainly *contains* information, but the phrase "smallest common bit of genetic material" and the reference to "a piece of DNA" both clearly point to a *physical* entity.

Sense 2: tangible substance. "Genetic material" definitely implies this. It's the physical substance involved.

Sense 5: things needed for doing or making something. It's a *component*.

Okay, let me check WordNet. Let me see if there's an entry for "genetic material." No? Probably not. Likely, "material" is the head.

In the realm of biology, "genetic material" unequivocally refers to the substance – that is, DNA. So, sense 2 is the clear winner: "the tangible substance that goes into the makeup of a physical object."

Hang on, is there any room for ambiguity? It's often referred to as "genetic material" (substance).

Therefore, my final judgment is that sense 2, the "tangible substance," is the best and most accurate fit in this context. It's the most appropriate here.

**Analyzing the Nuance of "Lost" in the Context of Tumor Genetics**

Okay, the target is "lose," surface form "lost," and the context screams genetics and tumor cells: "looking for the smallest common bit of genetic material lost in all tumor cells." My initial instinct is that "lost" here signifies a deletion or absence – the tumor cells no longer *have* this genetic material. It's a failure to retain or maintain it, a physical loss. Let's see...

I'm thinking of "lose%2:40:02::" and its senses... Sense 1 immediately resonates: "fail to keep or to maintain; cease to have, either physically or in an abstract sense." That perfectly describes the scenario. The genetic material is physically absent. It aligns perfectly with the biological concept of a genetic deletion or loss.

Sense 2 – allowing something to go out of sight – doesn’t fit. Nor does Sense 3 (misplacing) or Sense 4 (missing from one's possessions, like my glasses!). Sense 5 (loss of a person) is also off.

Thinking back to similar previous questions in this assignment, "lose" often denotes "fail to keep" when we're dealing with something like hair or weight. This confirms that this sense is in line with the current context.

Yes, Sense 1: "fail to keep or to maintain; cease to have, either physically or in an abstract sense" is the clear winner. The tumor cells have, in essence, ceased to possess this genetic material. This is the most appropriate and accurate representation of "lost" in this context.

**Analyzing the Target Word "Cells"**

Okay, the target word is "cells" within the context of "lost in all tumor cells." Given that this involves molecular biologists, genes, colon cancer, and biology in general, it's immediately clear that we're dealing with the biological meaning of "cell." Forget any other potential senses; this is biology 101. I'm going to look for the appropriate definition.

Let's see… Candidate 7: "definition=(biology) the basic structural and functional unit of all organisms…" Bingo! That’s it. That definition is a perfect fit. I can confidently assign Index 7.

**My Analysis of "Piece" in the Context of DNA**

Okay, here's how I'm thinking about this. The target word is "piece," and the context involves DNA. The question is, which sense of "piece" best fits "a piece of DNA"?

First, let's consider the senses I've got. I have a bunch, ranging from "bit" to "work of art" to "game equipment." DNA is a *physical* thing, a large molecule, so the relevant senses will involve physical objects or portions of them.

Immediately, senses like "an instance of some kind" (bit) and "a work of art" are out. Then I considered "a share of something," "game equipment," "a work of art," "a literary composition," "a period of indeterminate length," "a serving that has been cut," "a musical work," "a portable gun," "a distance," and "an item that is an instance of some type." I ruled them all out as not relevant.

Now, let's look at the remaining senses more closely. I have sense 7: "a portion of a natural object" and sense 8: "a separate part of a whole." Sense 7 has examples like "a piece of granite," which is good because DNA is a natural object (well, technically a macromolecule, but it is a natural substance.) Sense 8 has examples like "an important piece of the evidence."

The text mentions "bit of genetic material" in the surrounding text, which I'll keep in mind.

My instinct is leading me towards sense 7, the "portion of a natural object" sense, because DNA is a material substance. Also, the example of "piece of granite" is similar. If I'm thinking of "piece of granite" as a substance, then "piece of DNA" is also a piece of a mass substance.

I'm thinking about the synonyms for both of these senses to see if they give me more insight. The synonyms for sense 7 are "part" and the synonyms for sense 8 are no direct synonyms.

I'm checking similar corpora to see how "piece of DNA" is used. It looks like it's used in both senses, but I'm leaning toward the "portion of a natural object" sense.

Now, I'm checking the WordNet definitions more carefully. Sense 7 is defined as "a portion of a natural object." Sense 8 is defined as "a separate part of a whole." Again, with DNA, is it a *part* of the whole DNA molecule (sense 8), or a *portion* of a natural object (sense 7)?

I'm considering the hypernyms (the more general concepts). For sense 7, I get "part, portion -> natural object". For sense 8, I get "part, portion -> object". Since DNA is a natural object, this seems to support sense 7.

Then, I'm trying to remember how I've seen "piece of DNA" used before, in my experience. I'm thinking of it as a *portion* of the substance, so I'm gravitating towards sense 7. It's a "bit of genetic material," which really reinforces sense 7.

I'm looking at the previous context to check which sense fits. It refers to "the smallest common bit of genetic material". Yes, I'm now certain, that points more toward sense 7, a portion.

In WordNet, DNA is a macromolecule -> molecule -> ... -> natural object. So, in terms of hierarchy, sense 7 fits better.

I'm comparing "piece of granite" to "piece of DNA." Granite is a physical substance, a "portion of a natural object," and DNA, being genetic material, is very similar.

Now, let's examine the senses again. The context is "Such a piece of DNA would probably constitute a gene." It's talking about a *specific* portion of the material. So sense 7 seems the best fit.

Okay, let's look at the synonyms again. Sense 7 is "a portion of a natural object." Sense 8 is "a separate part of a whole."

I am making the final determination now.

Based on the definition and examples, and comparing to "piece of granite," I am going to select sense 7: "a portion of a natural object" (piece%1:17:00).

**Deconstructing the Nuances of "Probably" in a Scientific Context**

Okay, so the target is "probably" in the sentence "Such a piece of DNA would probably constitute a gene." My immediate instinct is to lean towards "with considerable certainty; without much doubt," the second sense we have here. This is the more common usage, the one where "probably" is synonymous with "likely" or "in all likelihood." My experience tells me that in scientific writing, we often use "likely" in similar constructions. I can immediately imagine, "Such a piece of DNA would likely constitute a gene," and it fits seamlessly.

I pause to examine the alternatives. Sense one, "easy to believe on the basis of available evidence" (plausible, credible), is also offered. It's listed with examples like "he will probably win the election," and this prompts a momentary blip – is this an error? However, a quick check against WordNet 3.0 confirms the nuance; I need to keep an open mind. In the sentence at hand, is it simply "easy to believe" based on the evidence, or something more?

I re-evaluate, considering this context. Yes, the finding of the "smallest common bit of genetic material lost" suggests "in all likelihood" it is a gene. But, could it also be described as "easy to believe" on this basis? Well, yes, but is it the *primary* meaning conveyed here? Let me reframe it as: "Such a piece of DNA would credibly/plausibly constitute a gene". Hmm, that shifts the emphasis slightly. While *plausible* is definitely a component, it's not the core meaning. Finding the shared element suggests *high probability*, not just *possibility*.

I revert back to the WordNet entries. WordNet 3.1 confirms this. It shows sense 2 is more closely linked to "with considerable certainty; without much doubt." The other sense is *also* a good fit, but it's not the *best* fit.

So, let me re-test. "Such a piece of DNA would likely constitute a gene." Perfect! What about "Such a piece of DNA would plausibly constitute a gene?" It's not *wrong*, but it dilutes the meaning. "Plausibly" suggests it *could* be, but "probably" conveys a higher degree of certainty, "more likely than not." Therefore, based on the context, sense 2—`probably%4:02:00::`—is the more fitting one, implying "very likely" or "in all likelihood."

**Analyzing the Meaning of "Constitute" in Context**

Okay, so the target lemma is "constitute," and the context is "Such a piece of DNA would probably constitute a gene." My immediate thought is, I need to figure out what "constitute" means here – does it mean "be," "make up," or something else?

I've got a few candidate senses: one about setting groundwork, and then two about forming or composing something. Sense 2, "form or compose" – synonyms like "represent," "make up," "comprise," and "be" – feels like a potential fit. Sense 3, "to compose or represent," has synonyms like "form" and "make." I'm seeing a distinction here.

The provided examples are useful. "This money constitutes my only income" clearly shows how 'constitute' can mean 'is.' "This wall forms the background..." highlights another nuance. I'm noting the subtle difference and thinking about how WordNet might handle it.

Checking WordNet confirms this distinction. Constitute%2:42:00:: is "form or compose," with synonyms that include "be." Constitute%2:42:03:: is "to compose or represent," with "form" and "make" as synonyms. Okay, so that's the established distinction in the lexical resource.

In our context, "Such a piece of DNA would probably constitute a gene," the potential paraphrase "Such a piece of DNA would probably be a gene" makes sense. The synonym "be" from Sense 2 clicks into place. I'm also comparing "make up, comprise, be" with "form, make." The DNA piece is *being* a gene or *making up* a gene.

"Is my only income" is a strong analog in Sense 2, which seems highly appropriate because it includes 'be' as a synonym for our context.

Let's look at the sense keys to solidify this: constitute%2:42:00:: form or compose (synonyms=represent, make up, comprise, be) and constitute%2:42:03:: to compose or represent: (synonyms=form, make).

In my experience, Sense 2 (constitute, represent, make up, comprise, be) is often used when A constitutes B, meaning A is B. In this instance, "a piece of DNA" is related to "a gene" as a constituent; in this case, "be" or "make up" is relevant.

So, after this analysis, I'm confident that Sense 2, "form or compose," is the best fit for this context. I'll flag that as the appropriate sense.

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

Alright, let's break this down. The core of my analysis revolves around the word "found" in the phrase "When they found it last winter." I need to determine the most accurate sense of "found" based on the preceding context: the researchers were experimentally looking for the smallest bit of genetic material lost in tumor cells, a bit of DNA that *might* constitute a gene.

I've got a list of candidate senses from WordNet, and after reviewing each, the initial temptation is toward sense 1, "come upon after searching," because the researchers *were* searching. But the search wasn't for something lost in the literal sense. The target was the *identity* and *location* of a specific genetic entity which, though elusive, wasn't a misplaced set of keys.

Sense 2, "make a discovery, make a new finding," also seems possible. They *were* potentially discovering something new, perhaps a new gene sequence. However, in that case, the focus would be on "finding something new" rather than actively looking for it in an experimental setup.

Sense 3, "establish after a calculation, investigation, experiment, survey, or study," begins to grab my attention. My reading of the context makes it clear that they *experimentally* crawled down the length of the chromosome. The examples in WordNet are very telling, particularly "The physicist who found the elusive particle won the Nobel Prize," is a great parallel. They were searching for, and subsequently *established* the existence/location of the gene. The synonyms for this sense - "determine, find out, ascertain" - all sound plausible as replacements for "found" in the context. Using "When they ascertained it," or "When they determined it," while maybe a bit formal, still fits well.

Sense 4, "discover or determine the existence, presence, or fact of," is worth a look but the context specifies that they are not only looking for the entity, but also the identity. This is better handled by a different sense, particularly 3.

Sense 8 is "make a discovery" with example "She found that he had lied to her." But this is not the right case, as there is no "that" clause.

So, I’m leaning toward sense 3. The fact that the search was experimental, coupled with the end goal of "nail[ing] the identity of the gene," which is essentially determining its existence and identity, points directly to sense 3. The search was not a mundane search for a lost thing or a new discovery; it was a targeted experimental inquiry to establish the identity and location of a specific gene. This is what "The physicist who found the elusive particle" captures. Therefore, even though "discover" (sense 2) is tempting, and the researchers are also making a discovery, sense 3 is more precise. "Found" here means that they *established* the existence and identity of the gene after a directed experimental search.

**Analyzing the Lemma "Last" in Context**

Okay, so the lemma I'm working with is "last," and the surface form is, of course, also "last." The sentence in question is, "When they found it last winter, Dr. Vogelstein was dubious that the search was over." Right away, the phrase "last winter" jumps out at me. My initial instinct is that we're talking about the winter immediately preceding the present one.

Let me quickly run through the candidate senses to make sure: unalterable, meaning *final* - definitely not right. Then there's "coming after all others in time or space" – potentially relevant, but feels too broad on its own. Next, "dying," "ultimate," "highest in extent," "lowest in rank," "closing," and "unlikely" are all clearly off-base.

That leaves us with the fifth sense: "past (immediately past)." Bingo! That feels like the strongest contender. The examples given – "last Thursday," "the last chapter we read" – are spot on. It perfectly captures that idea of something being recent, right before the current moment.

Just to be absolutely certain, I'll revisit sense number 2. "Coming after all others in time" - that makes sense in the phrase "the last day of the month" but even there, it implicitly refers to "the immediately past." It's essentially the *previous* day.

Yup, sense 5 is the winner. "Immediately past" is the precise meaning here. The winter *right before* the present. I'm confident.

**Analyzing the Nuances of "Dubious"**

Okay, so the target is "dubious" in "Dr. Vogelstein was dubious that the search was over." My initial thought is that it means he was doubtful or uncertain, but let's be precise. I need to differentiate the senses.

Looking at the definitions, I have: (1) "fraught with uncertainty or doubt," (2) "not convinced," and (3) "open to doubt or suspicion." The "dubious that" structure immediately flags sense 1 and its example, "they were doubtful that the cord would hold." Sense 2, "not convinced," seems less syntactically congruent.

The examples given are key: "dubious that..." seems directly parallel to "doubtful that..." from the sense 1 example, supporting it as the best semantic and structural fit, considering how it's used within the context sentence. Synonyms are noted as "doubtful" within the synset of the target word, "dubious", for sense 1.

WordNet 3.0 confirms my understanding. "Dubious" has three senses; in the relevant synset, it is listed as both "doubtful" and "dubious," solidifying its connection to sense 1: "fraught with uncertainty or doubt".

So, "Dr. Vogelstein was dubious that the search was over," can be paraphrased as "Dr. Vogelstein was doubtful that the search was over." This is because, "dubious" in the context of "dubious that" matches "doubtful" in "doubtful that". His doubts are specifically about whether the search is concluded. I'm going with sense 1.

**Deconstructing the "Search" in the Genetic Context**

Okay, so the target word is "search" in the sentence concerning Dr. Vogelstein's doubt. The context is genetic research, specifically, a team *looking* for a specific genetic "bit" lost in tumor cells. My initial thought goes to the most obvious sense of "search" – the act of *looking* for something. Let's break down the candidate senses quickly, keeping in mind my field of expertise.

*   **Sense 1:** Boarding and inspecting? No. Totally irrelevant.
*   **Sense 2:** Computer table lookup? Nope, the context is biological.
*   **Sense 3:** Examination of hypotheses? Not quite. Though, there's an element of hypothesis in the quest for the missing bit.
*   **Sense 4:** The act of *looking thoroughly to find* something. Synonym: hunt, hunting? Now we're talking. The researchers are essentially *hunting* for a gene.
*   **Sense 5:** An investigation seeking answers? Perhaps... *a thorough search of the ledgers reveals nothing*. It fits, too, in the sense that they're investigating.

So, the researchers are "experimentally crawled down the length of chromosome 17, looking for the smallest common bit of genetic material". That action, "looking for the smallest common bit", it directly maps to sense 4: "the activity of looking thoroughly in order to find something or someone". It is literally gene hunting, and "the search was over" makes perfect sense in that context. We are indeed hunting for a gene.

Is it sense 4 or 5? It's a fine distinction, but I think sense 4 fits the situation better. Considering both, sense 4 is an activity. Sense 5 is an investigation. It's about finding something, a physical entity, even if it is a piece of DNA. The "looking for the smallest common bit" matches sense 4 perfectly. I'm choosing sense 4. It's the action of hunting, or looking thoroughly.

**Analyzing the "Doubts" in Context**

Okay, so the lemma is "doubt," surface form "doubts," and the context is this researcher's reservations. Right away, I'm thinking about the potential senses. I've got two noun senses to consider: "doubt%1:07:00," which leans towards uncertainty about a *fact* or claim, and "doubt%1:09:00," which is more about the *state* of being unsure.

Let's break this down. "His doubts stemmed from the fact..." that phrasing suggests an internal cognitive state, a feeling of uncertainty. Now I'm mentally parsing these senses. "Doubt%1:07:00," with its synonyms like "dubiousness" and "question," seems geared toward evaluating the validity of something external – "the doubtfulness of his claim," perhaps. But here, it's about *his* doubts, internal to the researcher.

"Doubt%1:09:00," on the other hand, describes being unsure, like "he was in doubt about..." The plural form, "doubts," just *feels* right in this context. "His doubts" – his feelings of uncertainty.

I'm double-checking WordNet here, just to confirm these classifications: "doubt%1:07:00" is noun.attribute, and "doubt%1:09:00" is noun.cognition. The phrase "stemmed from the fact..." definitely points toward that cognitive state. It's not about the objective validity of something; it's about *his* subjective feelings.

So, if "doubt%1:07:00" is related to objective uncertainty—like the *doubtfulness* of a claim—that doesn't mesh with "his doubts" (which means personal, internal uncertainties). That definition would fit something like the “dubiousness of his claim”.

"Doubt%1:09:00" is the "state of being unsure of something." This is clearly what we're after, and if I’m honest the fact that "I have doubts" is such common phrasing seals it. I'm going with sense 2.

**Analyzing the Usage of "Stemmed"**

Okay, so the word I'm dealing with is "stemmed," and the root form is "stem." Let's see... the context is "His doubts stemmed from the fact that several years earlier a Princeton University researcher..." Right away, my expert intuition kicks in. This isn't about removing anything or stopping a flow, I can already rule those out. "Stemmed" here clearly means the doubts *originated* or *had their roots* in that fact. It's about cause and effect, the source of something. Let's see... a quick mental review of possible senses, I'm getting options like:

1.  Remove the stem from (like, a word or a plant).
2.  Stop the flow of a liquid.
3.  Grow out of, have roots in, originate in.
4.  Cause to point inward.

Hmm, yes, definitely sense 3. The other senses just don't fit the sentence's semantics. We're talking about the origin or cause of his doubts. It is similar to saying "The increase in the national debt stems from the last war". Therefore, "originated in" or "had roots in" is the most appropriate.

**Analyzing "Fact" in Context**

Okay, so the target word here is "fact" in "His doubts stemmed from the fact that...". The phrase "the fact that..." presents a proposition, and I need to determine the most accurate sense of "fact" in this construction. WordNet offers a few possibilities, so I'll consider them systematically.

First, there's "a statement or assertion of verified information" (fact%1:10:01). Then, "a piece of information about circumstances that exist or events that have occurred" (fact%1:09:01), "a concept whose truth can be proved" (fact%1:09:02), and finally "an event known to have happened or something known to have existed" (fact%1:26:01).

The phrase "the fact that..." is pretty common, and I need to nail down which sense fits. It usually introduces a clause that presents something true. Given the sentence "His doubts stemmed from the fact that several years earlier...", I'm thinking it's about the "piece of information," that is fact%1:09:01, or, possibly, about an event or circumstance which is known (fact%1:26:01).

I recall that "the fact that..." often refers to an event or circumstance. But it could also be the corresponding information. I'd ideally consult a corpus like SemCor to see how this construction is typically tagged. I'm leaning toward the "information" sense because the clause gives details on why the doubts exist.

Now, let's break down the hypernyms: information is a cognition. Thinking about the phrase "the fact that," it is referring to the actual circumstance. "His doubts stemmed from the fact that [something had been discovered...]" implies a specific circumstance. If I break it down into the core meaning, is it the fact or event that is causing the problem?

I'm starting to think the event sense, fact%1:26:01, also applies. "The fact is the circumstance or event." However, let's keep fact%1:09:01 in mind too.

Looking back at the definitions, I'm thinking "a piece of information about circumstances that exist or events that have occurred" (fact%1:09:01) seems most suitable here. "The fact that" introduces a clause that gives a piece of information. The subordinate clause specifies *why* there are doubts. So the fact here is this specific piece of information.

To verify, let's look at the example of fact%1:09:01. "First you must collect all the facts of the case". "the fact that..." typically tagged as fact%1:09:01 or fact%1:26:01. Let me consider the other senses again: 1. sense_key=fact%1:10:01::, 2. sense_key=fact%1:09:01::, 3. sense_key=fact%1:09:02::, 4. sense_key=fact%1:26:01::.

I'm leaning towards sense 2: fact%1:09:01::. I'm double-checking. Fact%1:09:01: "a piece of information about circumstances that exist or events that have occurred". Is "the fact that p" is information or an event? And it is overwhelmingly tagged as fact%1:09:01 in SemCor. "the fact that he had not..." is fact%1:09:01.

So, yes, the sense here is fact%1:09:01.

**Analyzing the Word "Several" in Context**

Okay, so the task is to pinpoint the specific meaning of "several" in the phrase "several years earlier." Let's break this down. First, the word "several" is clearly modifying the count noun "years," so we need a sense that works with a countable noun.

Now, let's consider the candidate senses. Sense 1, with the definition "distinct and individual," is not quite right. The example "three several times" implies distinct instances, which doesn't fit the context of years.

Sense 3, "considered individually" or "respective," also doesn't seem to apply here. The example "specialists in their several fields" indicates separate areas of expertise, not a duration of time.

That leaves us with Sense 2: "of an indefinite number more than 2 or 3 but not many." That's the winner! This definition, specifically the part about an "indefinite number more than 2 or 3 but not many," perfectly encapsulates the meaning of "several" in the context of "several years earlier". The examples given, like "several letters came in the mail" and "several people were injured in the accident," are similar. So the sense index is 2.

**Analyzing the Nuances of "Years"**

Okay, so the phrase is "several years earlier," and I need to pinpoint the correct meaning of "years" here. Let's break it down, drawing on my understanding of semantics and context. First, I have to consider the core sense of the word: a "year" as a duration, a cycle, or a named portion of the calendar. This immediately brings to mind "a period of time containing 365 (or 366) days," which I'll relate to "twelvemonth," as well as the more obvious term, "yr." This candidate, makes the most sense.

I'm ruling out "orbital period" or any other cyclical phenomenon that is not the same duration, and the "regular part of a calendar year," like a "school year" seems off. Lastly, "class/graduating class" is clearly irrelevant.

Therefore, sense 1, the straightforward definition of a calendar year or a 365-day period, is definitely the best fit for this phrase.

**Deconstructing "Earlier"**

Okay, so the target word is "earlier" in the phrase "...several years earlier..." Right away, I'm thinking chronologically. It's indicating a point in time *before* the current reference, so, essentially "previously" or "in the past." I quickly run through the different senses of "earlier." There's the straightforward temporal sense – "before," which seems like the primary definition. There's the comparative sense, related to "sooner." And then a sense of "in the first place" or "originally".

In this context, it's clear: "several years earlier" is functionally identical to "several years before." The comparative sense, "sooner," doesn't quite capture the temporal nuance of "prior to a specific point in the past". So, I go with the direct meaning.

Let's verify it. I check the definitions: Sense 1 is explicitly "earlier in time; previously; before". Sense 2 describes something comparative, like "sooner". Given the phrase, "several years before" works perfectly. "Several years sooner" doesn't quite gel with this past reference in the same way, while "several years before" does. I am thinking, "earlier in time; previously; before" is a perfect fit.

I'm confident; the first sense is the correct one. The adverbial usage here is clearly temporal.

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

Okay, so the target is "found" in the context of a scientific discovery, specifically "Arnold Levine, had found in experiments with mice that a gene...". My immediate thought is to consider the different senses this verb can take on. I need to pinpoint the most accurate sense.

My initial candidate senses include:

*   **Sense 2:** "make a discovery." This seems plausible, but usually it involves a noun phrase (NP) directly after the verb, not a "that" clause. Example: "Roentgen discovered X-rays".
*   **Sense 3:** "make a discovery (find that...)." This involves a *that*-clause and does fit the structure of the target sentence. It is, by definition, a *discovery*, which is not entirely inaccurate.
*   **Sense 13:** "establish after a calculation, investigation, experiment, survey, or study." Bingo! The presence of "in experiments" is a strong indicator. I'm leaning heavily towards this one.
*   **Sense 15:** "discover or determine the existence, presence, or fact of." Could also work, but 13 is the better fit.

I see that senses 3 and 13 both take that-clauses, with a subtle difference. Sense 3, by definition, "make a discovery (find that...)." I will come back to this. Sense 13, I remember, also has related words like "determine", "find out" and "ascertain", which also take that-clauses.

Let's evaluate the sentence again in the context of the potential word senses: "Arnold Levine, had found in experiments with mice that a gene called p53 could transform...". Sense 13's definition fits perfectly: "establish after an experiment".

I looked up "find out, determine, ascertain" in WordNet, and they're all defined as: "establish after a calculation, investigation, experiment, survey, or study". Perfect match!

So, the next question is if the examples from synsets are applicable. Checking sense 13: "find the product of two numbers; The physicist who found the elusive particle won the Nobel Prize". Wait! Is the second one a NP or a "that"-clause? If "found the elusive particle" is a NP, this supports the validity of the example.

Next, I look at the examples for sense 3: "She found that he had lied to her." It's clear that it also takes a that-clause: This meaning is "come to know" something. But here, "found" is related to an "experiment".

The context is "found in experiments with mice that...". Sense 13 is "establish after an experiment", and that fits perfectly. Sense 3 is about a discovery (find that...), but doesn't have an indicator "experiment". In any event, Sense 13 has the exact same definition! I choose 13.

Now, let's look closer at sense 13. "determine that..." "ascertain that..." "find out that...". Yes, determine and find out frequently take that-clauses. "Arnold Levine, had found in experiments with mice that a gene..." -> Arnold Levine had determined / found out / ascertained in experiments with mice that...

Finally, let's review the larger context of the passage. I am evaluating different instances of "found" and their relationship: "found it," "had found...that," and "deletion Dr. Vogelstein found."

*   "found it" - is about detecting the existence of something. That is, 15, or 2 or 16.
*   "had found...that" - I believe is definitively 13.
*   "deletion Dr. Vogelstein found" - This is probably 15.

Therefore, since "had found in experiments" means "had found out, determined, ascertained", I am choosing **Sense 13.**
