Target lemma: parent
Target surface form: parent
Context:
He theorized that in the eye cancer, an infant inherited a damaged copy of a gene from one parent and a normal copy from the other. The tumor, he suggested, developed when the second, normal copy also was damaged. But there was no way to prove Dr. Knudson's "two-hit "theory. Back then, scientists had no way of ferreting out specific genes, but under a microscope they could see the 23 pairs of chromosomes in the cells that contain the genes. Occasionally, gross chromosome damage was visible. Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a <t>parent</t> who had had the disease. Under a microscope he could actually see that a bit of chromosome 13 was missing.

Candidate senses:

*   Target lemma: `parent`
    *   Target surface form: `parent`
    *   Context: "Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a <t>parent</t> who had had the disease."
    *   Candidate senses:
        1.  `parent%1:18:00::`: a father or mother; one who begets or one who gives birth to or nurtures and raises a child; a relative who plays the role of guardian.
        2.  `parent%1:03:00::`: an organism (plant or animal) from which younger ones are obtained.

    *   The sentence discusses children inheriting a damaged copy of a chromosome from a "parent".
    *   The context is medical/genetic (eye cancer, genes, chromosomes).
    *   The "parent" here refers to the biological father or mother of the children.

    *   Sense 1: "a father or mother; one who begets or one who gives birth to or nurtures and raises a child..." (Focuses on the human/familial relationship).
    *   Sense 2: "an organism (plant or animal) from which younger ones are obtained" (A more general biological definition).

    *   While Sense 2 is biologically accurate, Sense 1 specifically mentions "father or mother" and "one who begets", which fits the context of "children" inheriting genes from their parents perfectly. In common English usage, when referring to human children and their biological progenitors, "parent" (Sense 1) is the standard term. Sense 2 is often used in botany or zoology for non-human organisms or general biological processes.
    *   The text mentions "children", which strongly points towards the human-centric definition of "parent" (Sense 1).

    *   Sense 1 is the most precise fit for "children... inherited... from a parent".

*   Target lemma: "actually"
    *   Target surface form: "actually"
    *   Context: "Under a microscope he could <t>actually</t> see that a bit of chromosome 13 was missing."
    *   Surrounding context: Dr. Knudson was investigating the "two-hit" theory. Scientists couldn't ferret out specific genes, but they could see chromosomes. He found that some children had inherited a damaged copy. He could *actually* see the missing bit under a microscope.

    *   Sense 1: `actually%4:02:01::` | definition=in actual fact | synonyms=really | examples=to be nominally but not actually independent; no one actually saw the shark. (Focus: Factuality, reality vs. nominal/theoretical).

    *   The sentence says: "Under a microscope he could actually see that a bit of chromosome 13 was missing."
    *   The previous sentence mentions that scientists had no way of ferreting out specific genes, but they could see chromosomes.
    *   The use of "actually" here emphasizes that the observation was a real, physical fact (he could see it with his own eyes), contrasting the theoretical "two-hit" theory or the inability to see genes.
    *   Is it "surprisingly" (Sense 2)? Not necessarily surprising in the sense of "contrary to expectation" in a shocking way, but rather confirming a hypothesis.
    *   Is it "in actual fact" (Sense 1)? Yes. He didn't just infer it; he *actually* (really/in fact) saw it.
    *   Is it "at the present moment" (Sense 3)? No.
    *   Is it a sentence modifier (Sense 4)? No, it's an adverb modifying the verb "see".

    *   Sense 1: "in actual fact" / "really". Example: "no one actually saw the shark". This matches "he could actually see that a bit of chromosome 13 was missing."
    *   Sense 2: "surprisingly". Example: "she actually spoke Latin". While there's a slight element of "despite the difficulty of seeing genes, he could actually see the chromosome damage," the primary meaning is the factuality of the observation.

    *   The context contrasts the inability to see genes with the ability to see chromosomes. "He could actually see" means he was able to observe it in reality/fact. This aligns best with Sense 1.

    *   Sense 1: in actual fact / really.
    *   Sense 2: surprisingly.
    *   Sense 3: at the present moment.
    *   Sense 4: sentence modifier.
    *   The usage "could actually see" is a classic use of "actually" meaning "really" or "in fact".

    *   Context: "Under a microscope he could actually see that a <t>bit</t> of chromosome 13 was missing."
    *   Meaning: A small piece or fragment of a chromosome.

    *   1: `a small piece or quantity of something` (synonyms: spot; examples: spot of tea, bit of paper)

    *   11: `the cutting part of a drill`

    *   The context describes a "bit of chromosome 13" being missing.
    *   A chromosome is a physical structure. A "bit" of it is a small piece or fragment.
    *   Sense 1: "a small piece or quantity of something". This is very general.
    *   Sense 2: "a small fragment of something broken off from the whole". This fits well because a piece of a chromosome is missing (broken off/deleted).
    *   Sense 8: "a small fragment" (synonym: snatch). This is usually used for non-physical things like conversation.

    *   Sense 1 is very broad ("a bit of paper").
    *   Sense 2 is more specific to fragments broken off from a whole ("a bit of rock").
    *   In genetics, a deletion is a piece of the chromosome that is missing/broken off.
    *   Comparing Sense 1 and Sense 2: Sense 1 is often used for quantities (a bit of tea) or generic small pieces. Sense 2 emphasizes the "fragment" aspect of something that was once part of a larger whole.
    *   Looking at the examples: "a bit of paper" (Sense 1) vs "a bit of rock caught him in the eye" (Sense 2).
    *   A missing piece of a chromosome is more like a fragment (Sense 2) than a generic quantity (Sense 1).

    *   Wait, let me re-read Sense 1: "a small piece or quantity of something".
    *   Let me re-read Sense 2: "a small fragment of something broken off from the whole".
    *   In the context "a bit of chromosome 13 was missing", the "bit" is the part that is gone. It was part of the whole chromosome.
    *   Sense 2 seems more precise for a physical fragment missing from a larger structure.

    *   Sense 1: "a small piece or quantity of something" (spot of tea, bit of paper).
    *   Sense 2: "a small fragment of something broken off from the whole" (chip, flake, fleck, scrap).
    *   A missing piece of a chromosome is essentially a fragment that is no longer there.

    *   Is it a "quantity" (Sense 1) or a "fragment" (Sense 2)?
    *   "A bit of paper" (Sense 1) could be a small piece.
    *   "A bit of rock" (Sense 2) is a fragment.
    *   A chromosome is a physical structure. A missing part of it is a fragment.

    *   Sense 1: `bit%1:23:01::`
    *   Sense 2: `bit%1:17:00::`
    *   Looking at WordNet's hierarchy (if I recall), `bit%1:17:00` is under `fragment`, and `bit%1:23:01` is under `piece`.
    *   "A bit of chromosome" is a piece/fragment.
    *   Let's look at the synonyms for Sense 2: chip, flake, fleck, scrap.
    *   Let's look at the synonyms for Sense 1: spot.
    *   "A bit of chromosome" fits "piece" (Sense 1) or "fragment" (Sense 2).
    *   Usually, when something is "missing" from a larger physical structure, "fragment" or "piece" works.
    *   Let's re-evaluate Sense 1: "a small piece or quantity of something".
    *   Let's re-evaluate Sense 2: "a small fragment of something broken off from the whole".
    *   The context says "a bit of chromosome 13 was missing". This implies it was once part of the whole and is now gone (broken off/deleted). This aligns perfectly with Sense 2.

    *   Sense 1: a bit of paper (could be a small piece, not necessarily broken off).
    *   Sense 2: a bit of rock (a fragment broken off).
    *   A missing piece of a chromosome is a fragment that has been deleted (broken off).

    *   Sense 1: `bit%1:23:01::`
    *   Sense 2: `bit%1:17:00::`

    *   2. sense_key=bit%1:17:00:: | definition=a small fragment of something broken off from the whole
    *   The context "a bit of chromosome 13 was missing" strongly suggests a fragment of the whole.

    *   Is "a bit of paper" (Sense 1) different from "a bit of rock" (Sense 2)?
    *   A "bit of paper" is often just a small piece.
    *   A "bit of rock" is a fragment.
    *   A chromosome is a biological structure. A missing part is a fragment.

    *   Sense 1: a small piece or quantity.
    *   Sense 2: a small fragment broken off from the whole.
    *   The missing piece of the chromosome was part of the whole chromosome. Therefore, Sense 2 is the most precise.

Context:
But there was no way to prove Dr. Knudson's "two-hit "theory. Back then, scientists had no way of ferreting out specific genes, but under a microscope they could see the 23 pairs of chromosomes in the cells that contain the genes. Occasionally, gross chromosome damage was visible. Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease. Under a microscope he could actually see that a bit of chromosome 13 was missing. He <t>assumed</t> the missing piece contained a gene or genes whose loss had a critical role in setting off the cancer. But he did not know which gene or genes had disappeared.

    *   The context describes a biological structure (chromosome 13).
    *   A "bit" of the chromosome was missing.
    *   The "missing piece" refers to that missing bit of the chromosome.

    *   Sense 1 is very general ("separate part of a whole").
    *   Sense 3 specifically mentions "a portion of a natural object" and gives the example "piece of granite". A chromosome is a natural object.
    *   Sense 5 ("an instance of some kind") is more abstract (e.g., "piece of work").
    *   Sense 8 ("serving that has been cut") is for food.

    *   The context says "a bit of chromosome 13 was missing" and then refers to it as the "missing piece".
    *   A chromosome is a physical, natural object.
    *   Sense 3 ("a portion of a natural object") fits perfectly.

    *   Sense 1: "a separate part of a whole" - This is a broad category.
    *   Sense 3: "a portion of a natural object" - This is more specific and fits the biological context of a chromosome.

    *   Wait, let me re-read Sense 1 and Sense 3.
    *   Sense 1: "a separate part of a whole" (Example: "an important piece of the evidence")
    *   Sense 3: "a portion of a natural object" (Example: "he needed a piece of granite")
    *   A chromosome is a natural object. A missing segment of a chromosome is a portion of that natural object.

    *   Is a chromosome a "natural object"? Yes.
    *   Is a missing segment a "portion" of it? Yes.
    *   Is it a "separate part of a whole"? Yes, but Sense 3 is more specific to the nature of the object (natural).

    *   Let's check Sense 5 again: "an instance of some kind" (Synonym: bit). The text says "a bit of chromosome 13", but "piece" here refers to the physical part of the chromosome, not an abstract instance.

    *   Comparing Sense 1 and Sense 3 again:
        Sense 1: "a separate part of a whole"
        Sense 3: "a portion of a natural object"
        In many WordNet-based tasks, if a more specific sense (like "natural object") exists and fits, it's preferred over the most general sense.

    *   Let's look at the examples for Sense 1: "an important piece of the evidence". Evidence is abstract.
    *   Let's look at the examples for Sense 3: "he needed a piece of granite". Granite is a natural physical substance. A chromosome is a natural physical structure.

    *   Therefore, Sense 3 is the best fit.

    *   "the missing piece contained a gene or genes whose loss had a critical role..."
    *   Is it a "gradual decline" (Sense 2)? No, it's a missing piece.
    *   Is it "the act of losing" (Sense 3)? It's not about the *act* of losing a game or a competition, but the state of being gone or the event of disappearing.
    *   Is it "the disadvantage that results" (Sense 4)? The loss *caused* the cancer, but the "loss" itself refers to the fact that the genes are gone.
    *   Is it "something that is lost" (Sense 1)? This sense often refers to the object lost (e.g., "the car was a total loss").
    *   Wait, let's re-evaluate Sense 2: "gradual decline in amount or activity". Weight loss is a common example. In biology, "loss of function" or "loss of a gene" often fits the pattern of a reduction or disappearance of something.
    *   Let's look at Sense 3 again: "the act of losing someone or something".
    *   Let's look at Sense 1 again: "something that is lost".

    *   "loss of a gene"
    *   Is it the *act* of losing it (Sense 3)?
    *   Is it the *fact* that it is gone (Sense 1)?
    *   Is it a *decline* (Sense 2)?

    Let's compare:
    - Sense 1: "something that is lost" (the car was a total loss).
    - Sense 2: "gradual decline in amount or activity" (weight loss).
    - Sense 3: "the act of losing someone or something" (his loss was a shock).

    In the sentence "genes whose loss had a critical role", "loss" refers to the disappearance or absence of the genes.

    Looking at WordNet's structure for "loss":
    - loss%1:04:00 (the act of losing)
    - loss%1:22:00 (gradual decline)
    - loss%1:21:01 (something that is lost)

    If we say "the loss of a gene", we are usually referring to the event or the state of it being gone.

    Let's re-read Sense 2: "gradual decline in amount or activity". Weight loss is the loss of mass. Gene loss is the loss of genetic material. While "gradual" might not fit perfectly (it could be a sudden deletion), "loss of [substance/component]" often maps to this sense in biological contexts (like "loss of hearing", "loss of memory", "weight loss").

    Wait, let's look at Sense 3 again: "the act of losing someone or something". Example: "everyone expected him to win so his loss was a shock". This is more about defeat.

    Let's look at Sense 1: "something that is lost". Example: "the car was a total loss". This is the object itself.

    Let's reconsider Sense 2: "gradual decline in amount or activity". Example: "weight loss". This fits the pattern "loss of [something]" where the something is a quantity or a part of a whole.

    Wait, let's check if there's another sense.
    Sense 4: "the disadvantage that results from losing something". "his loss of credibility led to his resignation".

    In "genes whose loss had a critical role", the "loss" is the fact that the genes are missing.

    Let's compare "weight loss" (Sense 2) and "loss of credibility" (Sense 4).
    Weight loss is a reduction in amount.
    Loss of credibility is a deprivation/disadvantage.

    Is "loss of a gene" a reduction in amount (Sense 2) or a deprivation (Sense 4)?
    Actually, in biological terms, "loss of a gene" is the absence of that gene.

    Let's look at Sense 2 again: "gradual decline in amount or activity".
    Is gene loss always gradual? No. But "weight loss" is the prototypical example.

    Let's look at Sense 3 again: "the act of losing someone or something".
    If I lose my keys, that's the act of losing.

    Let's look at Sense 1: "something that is lost".
    If the gene is the "loss", that doesn't make sense.

    Let's re-examine Sense 2: "gradual decline in amount or activity".
    If we consider "loss" as the process of losing something (like weight), "loss of a gene" fits this pattern of "loss of [X]".

    Let's check Sense 4 again: "the disadvantage that results from losing something".
    "his loss of credibility led to his resignation".
    The loss of the gene led to the cancer. This is very similar. The "loss" (the fact that it's gone) is the cause.

    Wait, let's look at the examples for Sense 2 again: "weight loss; a serious loss of business".
    These are reductions in amount.
    "Loss of a gene" is a reduction in the amount of genetic material (specifically, the removal of a gene).

    Let's look at Sense 3 again: "the act of losing someone or something".
    Example: "everyone expected him to win so his loss was a shock". This is specifically about losing a contest.

    Let's look at Sense 1: "something that is lost".
    Example: "the car was a total loss".

    Let's look at Sense 4: "the disadvantage that results from losing something".
    Example: "his loss of credibility led to his resignation".

    Comparing Sense 2 (decline in amount) and Sense 4 (disadvantage/deprivation):
    "Loss of a gene" -> The gene is gone.
    Is it a "decline in amount" or a "deprivation"?
    In biological contexts, "loss of [protein/gene/function]" is almost always categorized as a reduction or disappearance.

    Let's double-check Sense 2's definition: "gradual decline in amount or activity".
    Is the loss of a gene "gradual"? Not necessarily. But "weight loss" is the example.

    Let's look at Sense 3 again. "the act of losing someone or something".
    If you lose your wallet, that's the act of losing.
    If a cell loses a gene, that's the act of losing.

    Wait, let's look at the context again: "a bit of chromosome 13 was missing. He assumed the missing piece contained a gene or genes whose loss had a critical role..."
    The "loss" refers to the fact that the genes are missing.

    Let's search for "loss of gene" in WordNet-like contexts.
    Usually, "loss of [biological component]" is treated as a reduction in amount or the state of being gone.

    Let's re-evaluate Sense 2 vs Sense 4.
    Sense 2: weight loss, loss of business.
    Sense 4: loss of credibility, deprivation.

    "Loss of a gene" is more like "loss of weight" (a physical thing is gone) than "loss of credibility" (an abstract quality is gone).

    Wait, let me look at Sense 3 again. "the act of losing someone or something".
    If I say "the loss of the gene caused the cancer", am I talking about the *act* of losing it or the *fact* that it is gone?
    Usually, it's the fact that it's gone (the state of absence).

    Let's look at Sense 2 again. "gradual decline in amount or activity".
    If you lose one gene, is that a "decline in amount"? Yes, you have one fewer gene.

    Let's look at Sense 1: "something that is lost".
    "the car was a total loss". (The car is the loss).
    In "genes whose loss", the genes are not the loss; the *loss* is the thing that happened to the genes.

    Let's look at Sense 3 again: "the act of losing someone or something".
    If "loss" = "the act of losing", then "the act of losing the genes had a critical role". This makes sense.

    Let's compare Sense 2 and Sense 3 again.
    Sense 2: gradual decline in amount or activity.
    Sense 3: the act of losing someone or something.

    "Weight loss" (Sense 2) is a process.
    "Loss of a gene" can be a process or an event.

    Let's look at Sense 4: "the disadvantage that results from losing something".
    "his loss of credibility led to his resignation".
    "the loss of the gene led to the cancer".
    This also fits very well. The "loss" is the deprivation of the gene's function.

    Wait, let's look at the synonyms for Sense 4: "deprivation".
    Is the loss of a gene a "deprivation"? Yes, the cell is deprived of that gene.

    Let's look at Sense 2 again: "gradual decline in amount or activity".
    Is the loss of a gene a "gradual decline"? Not usually. It's usually a deletion.

    Let's look at Sense 3 again: "the act of losing someone or something".
    Example: "everyone expected him to win so his loss was a shock".
    This example is about losing a game. But the definition is "the act of losing someone or something".
    If you lose your keys, that's the act of losing.

    Let's think about "loss of [X]" where X is a physical part.
    "Loss of blood" -> Sense 2 (decline in amount).
    "Loss of a limb" -> Sense 3 (the act of losing) or Sense 4 (the deprivation)?

    Actually, "loss of blood" is a decline in the amount of blood.
    "Loss of a gene" is a decline in the amount of genetic material.

    Let's re-read Sense 2: "gradual decline in amount or activity".
    "Weight loss" is the classic example.
    "Loss of business" is another.

    Let's re-read Sense 3: "the act of losing someone or something".
    "everyone expected him to win so his loss was a shock".

    Let's re-read Sense 4: "the disadvantage that results from losing something".
    "his loss of credibility led to his resignation".

    In the context "genes whose loss had a critical role in setting off the cancer", the "loss" is the cause.
    The cause is the *absence* of the gene.
    Is the absence a "decline in amount" (Sense 2), an "act of losing" (Sense 3), or a "deprivation" (Sense 4)?

    If we look at "loss of function" in biology, it's often a "loss-of-function mutation". This means the function is gone.

    Let's try to find the most fitting one.
    Sense 2: gradual decline in amount or activity.
    Sense 3: the act of losing someone or something.
    Sense 4: the disadvantage that results from losing something.

    If I say "the loss of the gene", I'm talking about the fact that the gene is no longer there.
    This is most similar to "weight loss" (the weight is no longer there) or "loss of business" (the business is no longer there).

    Wait, "weight loss" is a reduction in the *amount* of weight.
    "Loss of a gene" is a reduction in the *amount* of genes (from 2 to 1, or 1 to 0).

    Let's check Sense 3 again. "the act of losing someone or something".
    If you lose your keys, the *act* of losing them is the event.
    The "loss of the gene" is the event of the gene disappearing.

    Let's look at Sense 4 again. "the disadvantage that results from losing something".
    The "loss of credibility" is the *state* of no longer having credibility, which is a disadvantage.
    The "loss of the gene" is the *state* of no longer having the gene, which is a disadvantage (it leads to cancer).

    This is tricky. Let's look at the examples again.
    Sense 2: weight loss, loss of business.
    Sense 4: loss of credibility.

    "Weight" and "business" (in the sense of volume) are quantities.
    "Credibility" is a quality.
    "A gene" is a discrete object.

    If you lose a discrete object, is that a "decline in amount" (Sense 2) or "the act of losing" (Sense 3)?
    If you lose *one* gene, you have fewer genes. That's a decline in amount.

    Let's think about "loss of a limb". Is that a decline in amount? Yes, you have fewer limbs. Is it the act of losing? Yes. Is it a deprivation? Yes.

    Let's look at the context again: "a bit of chromosome 13 was missing... genes whose loss had a critical role".
    The "loss" is the fact that the genes are missing.

    Let's compare:
    - "The loss of the gene caused the cancer."
    - "The weight loss caused the health improvement."
    - "The loss of credibility caused the resignation."

    In the first two, we are talking about the reduction/absence of something.
    In the third, we are talking about the negative consequence of no longer having something.

    Wait, Sense 4 says "the disadvantage that results from losing something".
    The "loss of credibility" *is* the disadvantage.
    The "loss of the gene" *is* the cause of the cancer. Is the loss itself the disadvantage, or is the cancer the disadvantage?
    The loss of the gene is the deprivation of the gene's function.

    Let's look at Sense 2 again: "gradual decline in amount or activity".
    Is "loss of a gene" a "decline in amount"?
    If you have 2 copies of a gene and you lose one, you have a decline in the amount of that gene.

    Let's look at Sense 3 again: "the act of losing someone or something".
    "everyone expected him to win so his loss was a shock".
    This example is very specific to losing a competition. But the definition is broader.

    Let's search for "loss of [gene/protein]" in a linguistic database.
    Often, "loss of [X]" where X is a biological component is mapped to the sense of "reduction in amount" or "disappearance".

    Let's re-examine Sense 2: "gradual decline in amount or activity".
    Example: "weight loss".
    This fits the "loss of [X]" pattern where X is a physical quantity.

    Let's re-examine Sense 3: "the act of losing someone or something".
    Example: "his loss was a shock" (losing a game).

    Let's re-examine Sense 4: "the disadvantage that results from losing something".
    Example: "his loss of credibility led to his resignation".

    If we have to choose the *best* one:
    "Loss of a gene" is most like "loss of weight" (Sense 2) or "loss of credibility" (Sense 4).
    Is a gene more like "weight" (a quantity) or "credibility" (a quality/status)?
    A gene is a physical thing, but its "loss" in this context refers to the absence of its function.

    Wait, let's look at Sense 2 again: "gradual decline in amount or activity".
    Is the loss of a gene "gradual"? No.
    Is "weight loss" always gradual? Usually.
    Is "loss of business" always gradual? Often.

    If "gradual" is a key part of Sense 2, then Sense 2 might be wrong.
    Let's look at Sense 3: "the act of losing someone or something".
    If you lose a gene, that's the act of losing it.

    Let's look at Sense 4: "the disadvantage that results from losing something".
    The loss of the gene is the deprivation of the gene.

    Let's think about "loss of hearing". Is that a gradual decline (Sense 2), the act of losing (Sense 3), or a deprivation (Sense 4)?
    "Loss of hearing" is usually a gradual decline.

    What about "loss of a limb"?
    That's not gradual. It's the act of losing it (Sense 3) or the deprivation (Sense 4).

    What about "loss of a gene"?
    It's not gradual. It's the act of losing it or the deprivation.

    Let's look at Sense 3 again: "the act of losing someone or something".
    Example: "everyone expected him to win so his loss was a shock".
    This example is about losing a game, but the definition is "the act of losing someone or something".
    If you lose your keys, that's the act of losing.
    If a cell loses a gene, that's the act of losing.

    Let's look at Sense 4 again: "the disadvantage that results from losing something".
    Example: "his loss of credibility led to his resignation".
    The loss of the gene led to the cancer.

    This is very similar. Let's compare "loss of credibility" and "loss of a gene".
    Credibility is an abstract quality.
    A gene is a physical entity.

    Wait, let's look at Sense 1: "something that is lost".
    "the car was a total loss".
    This means the car *is* the loss.
    In "genes whose loss", the genes are not the loss.

    Let's look at Sense 2 again: "gradual decline in amount or activity".
    If we ignore the word "gradual", "decline in amount" fits "loss of a gene" (you have fewer genes).

    Let's look at Sense 3 again: "the act of losing someone or something".
    If we use this, "the act of losing the genes had a critical role".

    Let's look at Sense 4 again: "the disadvantage that results from losing something".
    If we use this, "the deprivation of the genes had a critical role".

    Which one is most common for "loss of [biological component]"?
    In many cases, "loss of [X]" is used to mean the *absence* of [X].
    "Loss of function", "loss of expression", "loss of a gene".

    Let's look at the options again.
    1. something that is lost
    2. gradual decline in amount or activity
    3. the act of losing someone or something
    4. the disadvantage that results from losing something
    5. experience of losing a loved one
    6. business loss
    7. military personnel loss
    8. death

    If I have to choose between 2, 3, and 4...
    Sense 2 is about amount.
    Sense 3 is about the act.
    Sense 4 is about the disadvantage/deprivation.

    "Loss of a gene" -> The gene is gone.
    This is a reduction in the amount of that gene.
    Is it "gradual"? Not necessarily.
    Is it "the act of losing"? Yes.
    Is it "the disadvantage"? Yes, the absence is the disadvantage.

    Let's look at the example for Sense 4: "his loss of credibility led to his resignation".
    The "loss of credibility" is the *fact* that he no longer has credibility.
    The "loss of the gene" is the *fact* that the cell no longer has the gene.

    This seems like a very strong match. The "loss" is the state of no longer having the thing, and that state is what leads to the consequence (resignation / cancer).

    Let's double-check Sense 2 again: "gradual decline in amount or activity".
    "Weight loss" is a reduction in amount.
    "Loss of business" is a reduction in amount.
    "Loss of a gene" is a reduction in amount.
    But "gradual" is in the definition. Gene loss is often sudden (a deletion).

    Let's double-check Sense 3 again: "the act of losing someone or something".
    "everyone expected him to win so his loss was a shock".
    This example is about defeat.

    Let's look at Sense 4 again: "the disadvantage that results from losing something".
    Synonym: "deprivation".
    "Loss of a gene" = "Deprivation of a gene".
    This fits well.

    Wait, let me think about "loss of blood" again.
    Is "loss of blood" a "gradual decline in amount" (Sense 2) or a "deprivation" (Sense 4)?
    It's a decline in amount.

    Is "loss of a gene" more like "loss of blood" or "loss of credibility"?
    "Loss of blood" is a physical quantity.
    "Loss of a gene" is a physical entity.
    "Loss of credibility" is an abstract quality.

    However, "loss of a gene" often refers to the *absence* of the gene's function, which is more like a deprivation.

    Let's search for "loss of [X]" in WordNet.
    "loss of hearing" -> Sense 2 (gradual decline).
    "loss of a friend" -> Sense 3 (the act of losing) or Sense 5 (experience of losing a loved one).
    "loss of a game" -> Sense 3 (the act of losing).
    "loss of a job" -> Sense 3 (the act of losing) or Sense 4 (the deprivation).

    If you lose your job, the "loss of your job" is the fact that you no longer have it, which is a deprivation.

    Let's look at the context again: "genes whose loss had a critical role in setting off the cancer".
    The "loss" is the cause.
    The cause is the *absence* of the gene.
    The absence of the gene is a deprivation of the gene's function.

    Let's compare Sense 2 and Sense 4 one more time.
    Sense 2: gradual decline in amount or activity.
    Sense 4: the disadvantage that results from losing something (deprivation).

    If the gene is gone, you have a "loss of [gene]".
    If the gene's function is gone, you have a "loss of [function]".
    Both of these are deprivations.

    Let's look at the example for Sense 2: "weight loss".
    Weight loss is the reduction of weight.
    Gene loss is the reduction of genes.

    Wait, I just found a similar example in a WordNet-based dataset.
    "loss of [biological function/component]" is often mapped to the sense of "deprivation" or "the act of losing".

    Let's look at Sense 3 again: "the act of losing someone or something".
    If we say "the loss of the gene", are we talking about the *act* of it being lost or the *fact* that it is gone?
    "the missing piece contained a gene or genes whose loss had a critical role"
    The "loss" refers back to the "missing piece".
    The piece is missing. The loss is the fact that it's missing.

    This points more towards Sense 4 (deprivation/disadvantage) or Sense 2 (decline in amount).

    Let's think about "loss of a gene" as "deprivation of a gene".
    That makes a lot of sense. The cell is deprived of the gene, and that deprivation causes cancer.

    Let's think about "loss of a gene" as "decline in amount of genes".
    That also makes sense, but "gradual" is a problem.

    Let's think about "loss of a gene" as "the act of losing a gene".
    That also makes sense, but the context is more about the *result* of the loss (the missing piece) than the *act* of losing it.

    Let's re-read Sense 4: "the disadvantage that results from losing something".
    Example: "his loss of credibility led to his resignation".
    This matches the structure "the loss of [X] led to [Y]" perfectly.
    "the loss of [genes] led to [cancer]".

    Let's double-check Sense 2 again: "gradual decline in amount or activity".
    Example: "weight loss".
    This is more like "the [X] loss led to [Y]".

    Let's double-check Sense 3 again: "the act of losing someone or something".
    Example: "his loss was a shock".
    This is more like "the loss was [X]".

    The structure "the loss of [X] led to [Y]" is a very strong match for Sense 4.

    *   Comparing "vital/indispensable" (Sense 4) vs "decisive/turning point" (Sense 5).
    *   In biological/medical contexts, a "critical role" usually means the factor is necessary for the outcome to occur.
    *   Let's look at the examples again:
        *   Sense 4: "a critical element of the plan" (essential).
        *   Sense 5: "a critical point in the campaign" (decisive moment).
    *   "A critical role in setting off the cancer" sounds more like an essential element (Sense 4) than a turning point in time (Sense 5). However, "decisive" (Sense 5 synonym) also fits well.
    *   Wait, let's re-read Sense 4: "urgently needed; absolutely necessary".
    *   Let's re-read Sense 5: "forming or having the nature of a turning point or crisis".
    *   Actually, "critical role" is a very common collocation for "essential" or "vital".
    *   Let's check if "critical" in "critical role" usually maps to "crucial" or "indispensable".
    *   In the context of "setting off the cancer", the loss of the gene is the *cause* or a *necessary condition*.
    *   If we look at the synonyms: Sense 4 (vital), Sense 5 (decisive).
    *   "The loss had a vital role" vs "The loss had a decisive role". Both work.

    *   Sense 4: indispensable, vital.
    *   Sense 5: crucial, decisive.
    *   In many dictionaries, "crucial" and "critical" are synonyms for "essential".

        *   Sense 5: `critical%5:00:00:crucial:00`
    *   "Indispensable" means you can't do without it. "Crucial" means it's the deciding factor.
    *   The loss of the gene is what *caused* (set off) the cancer. This makes it the decisive factor.
    *   But "critical role" is almost always used to mean "essential/vital".
    *   Let's re-evaluate Sense 5: "forming or having the nature of a turning point or crisis". The "setting off" part of the sentence aligns well with the "turning point" aspect of Sense 5.

    *   Let's re-read Sense 1: "the actions and activities assigned to or required or expected of a person or group". This is very specific to people.
    *   Let's re-read Sense 3: "what something is used for". This is more general ("something").
    *   If a gene has a role, it has a function. If the *loss* of a gene has a role, it means it contributed to the outcome.
    *   Comparing "function" (Sense 1) vs "function" (Sense 3).
    *   Sense 1's "function" is like "the function of a teacher".
    *   Sense 3's "function" is like "the function of an auger".
    *   A gene is more like a tool/component (auger) than a person (teacher).
    *   Therefore, Sense 3 is the most appropriate fit for a biological component's function.

    *   Context: "loss had a critical role in setting off the cancer"
    *   Sense 3: "what something is used for" / "function".
    *   Does "loss" have a "use"? Not exactly, but the "role" here means the part it played in the process.
    *   Let's check if there's a better fit.
    *   Sense 1: "actions and activities assigned to... a person or group". (Definitely not).
    *   Sense 2: "actor's portrayal". (Definitely not).
    *   Sense 4: "customary activity of a person". (Definitely not).
    *   By elimination, Sense 3 is the only one that can possibly apply to a non-human entity ("something").

    *   Sense 3: "what something is used for" | synonyms=function, purpose, use.
    *   In the sentence "the loss had a critical role", "role" is used as a synonym for "function" or "part".
    *   While "used for" is a bit narrow, "function" is a broad synonym.

    *   Sense 1: person/group.
    *   Sense 2: actor.
    *   Sense 3: something.
    *   Sense 4: person.
    *   The target is "loss" (of a gene), which is a "something".

    *   Sense 3 is the best fit.

Target lemma: set_off
Target surface form: setting off
Context:
But there was no way to prove Dr. Knudson's "two-hit "theory. Back then, scientists had no way of ferreting out specific genes, but under a microscope they could see the 23 pairs of chromosomes in the cells that contain the genes. Occasionally, gross chromosome damage was visible. Dr. Knudson found that some children with the eye cancer had inherited a damaged copy of chromosome No. 13 from a parent who had had the disease. Under a microscope he could actually see that a bit of chromosome 13 was missing. He assumed the missing piece contained a gene or genes whose loss had a critical role in <t>setting off</t> the cancer. But he did not know which gene or genes had disappeared.

*   Target lemma: `set_off`
    *   Target surface form: `setting off`
    *   Context: "...He assumed the missing piece contained a gene or genes whose loss had a critical role in <t>setting off</t> the cancer."

    *   Sense 1: `put in motion or move to act` (synonyms: trip, actuate, trigger, activate, spark off, spark). Example: "trigger a reaction".
    *   Sense 2: `leave` (synonyms: depart, part, start, set forth, set out). Example: "The family took off for Florida".
    *   Sense 3: `direct attention to, as if by means of contrast` (synonyms: bring out). Example: "This dress accentuates your nice figure!".
    *   Sense 4: `cause to burst with a violent release of energy` (synonyms: explode, detonate, blow up). Example: "We exploded the nuclear bomb".

    *   Sense 7: `provoke or stir up` (synonyms: incite, instigate, stir up). Example: "incite a riot".

    *   The context is about a genetic mutation (loss of a gene) that leads to the development of cancer.
    *   "setting off the cancer" means the loss of the gene triggered or caused the cancer to start.

    *   Sense 1: "put in motion or move to act" / "trigger". This fits well. Triggering a disease or a biological process is a common usage of "set off".
    *   Sense 6: "set in motion or cause to begin". This also fits.
    *   Sense 7: "provoke or stir up". Usually used for emotions or social unrest (riots).

    *   Sense 1 synonyms include "trigger" and "spark off". "Triggering cancer" is a very standard medical/biological phrase.
    *   Sense 6 is more general ("set the tour off to a good start").
    *   Comparing Sense 1 and Sense 6: Sense 1's synonyms (trigger, activate) are much more precise for a biological mechanism like cancer initiation.

    *   Sense 1: `put in motion or move to act` (trigger, activate).
    *   Context: "loss had a critical role in setting off the cancer."
    *   This matches the "trigger" meaning perfectly.
