    *   The phrase is "the 'standard' set of elements".
    *   "Elements" refers to chemical elements (carbon, hydrogen, oxygen, etc.).
    *   A "set of elements" in this context refers to a group of specific chemical elements that are considered necessary for life.

    *   Sense 2 (Mathematics) is about abstract collections of numbers or symbols. While "set" in science often borrows from mathematical set theory, the general meaning here is a group of things.
    *   Sense 10 (A group of things of the same kind that belong together and are so used) fits well. A "set of elements" is a group of elements that belong together (in the context of being necessary for life).

    *   Sense 2: "an abstract collection of numbers or symbols". Chemical elements aren't exactly numbers or symbols, though they are represented by them.
    *   Sense 10: "a group of things of the same kind that belong together and are so used". Chemical elements are "things of the same kind" (elements).

    *   Is it a mathematical set (Sense 2)? In a strict scientific sense, yes, but in general English, "a set of [things]" usually maps to Sense 10 unless it's explicitly a math problem.
    *   Is it a group of things (Sense 10)? Yes. "A set of elements" is a collection of items of the same category.

    *   Sense 10: "a group of things of the same kind that belong together and are so used" (e.g., a set of books, a set of golf clubs).
    *   The "standard set of elements" is a group of elements (same kind) that belong together (as the requirements for life).

    *   Sense 2 is specifically for mathematics.
    *   Sense 10 is the general "collection/group" sense.
    *   The context is biochemistry/astrobiology, not a mathematics paper.

    *   Sense 10 is the most appropriate.

    *   14: life sentence

    *   The sentence says: "...the 'standard' set of elements we think are absolutely necessary for life might not be so fixed..."
    *   This refers to the biological/chemical requirements for the existence of living organisms.
    *   It's not talking about a specific person's life (1, 4, 8, 11, 12).
    *   It's not talking about a biography (7).
    *   It's not talking about a life sentence (14).
    *   It's not talking about liveliness (2) or a motive (3).
    *   It's not talking about a mode of living (6) or human experience (13).
    *   It's comparing "living organisms" vs "nonliving ones" in the context of biochemistry and planetary environments.

    *   Sense 5: "the condition of living or the state of being alive" (Example: "life depends on many chemical and physical processes").
    *   Sense 9: "living things collectively" (Example: "the oceans are teeming with life").
    *   Sense 10: "the organic phenomenon that distinguishes living organisms from nonliving ones" (Example: "there is no life on the moon").

    *   The context mentions "the search for life beyond Earth", "recognize life", "extraterrestrial life", and "elements we think are absolutely necessary for life".
    *   Sense 10 ("the organic phenomenon that distinguishes living organisms from nonliving ones") fits perfectly with the scientific/biological context of searching for extraterrestrial life and the chemical requirements for it.
    *   Sense 5 is similar but more about the *state* of being alive.
    *   Sense 9 is about the *collection* of organisms.
    *   The phrase "necessary for life" in a scientific context usually refers to the phenomenon of life itself (the biological process/phenomenon).

    *   Sense 10: "the organic phenomenon that distinguishes living organisms from nonliving ones" (Example: "there is no life on the moon").
    *   This matches the "life beyond Earth" and "extraterrestrial life" theme perfectly.

    *   Sense 5: "the condition of living or the state of being alive" (Example: "life depends on many chemical and physical processes").
    *   Wait, the example for Sense 5 ("life depends on many chemical and physical processes") is *extremely* close to the target sentence ("elements we think are absolutely necessary for life").
    *   Let's re-read Sense 10: "the organic phenomenon that distinguishes living organisms from nonliving ones" (Example: "there is no life on the moon").
    *   The target sentence is about the *requirements* for life to exist.
    *   Is "life" here the *phenomenon* (10) or the *condition/state* (5)?
    *   In "necessary for life", "life" refers to the existence of living organisms.
    *   Looking at the examples:
        *   Sense 5: "life depends on many chemical and physical processes"
        *   Sense 10: "there is no life on the moon"
    *   The target sentence: "elements we think are absolutely necessary for life".
    *   This is almost a paraphrase of the Sense 5 example.

    *   Sense 5: condition of living / state of being alive.
    *   Sense 10: organic phenomenon distinguishing living from nonliving.
    *   In the context of "search for life beyond Earth", "life" often means "living organisms" (Sense 9) or "the phenomenon of life" (Sense 10).
    *   However, the specific phrase "necessary for life" aligns very strongly with the example provided for Sense 5.

    *   "The find is important in the search for life beyond Earth..." (Sense 9 or 10)
    *   "...researchers need to be able to recognize life..." (Sense 9 or 10)
    *   "...discovery of extraterrestrial life." (Sense 9 or 10)
    *   "...elements we think are absolutely necessary for life..." (Sense 5 or 10)

    *   Sense 5: "the condition of living or the state of being alive"
    *   Sense 10: "the organic phenomenon that distinguishes living organisms from nonliving ones"
    *   If we are talking about the *requirements* (elements) for life, we are talking about what allows the *state of being alive* (Sense 5) or the *phenomenon of life* (Sense 10) to occur.
    *   Let's look at the examples again.
        *   Sense 5: "life depends on many chemical and physical processes"
        *   Sense 10: "there is no life on the moon"
    *   The target sentence "elements we think are absolutely necessary for life" is logically equivalent to "life depends on [these] elements". This points strongly to Sense 5.

    *   Wait, let me double-check Sense 10 again. "the organic phenomenon that distinguishes living organisms from nonliving ones". This is a very broad definition.
    *   Let's look at Sense 9: "living things collectively". "Search for life beyond Earth" often means "search for living things".
    *   But "necessary for life" doesn't mean "necessary for living things collectively" as much as it means "necessary for the state of being alive".

    *   Target: "elements we think are absolutely necessary for life"
    *   Sense 5 Example: "life depends on many chemical and physical processes"
    *   The match is very strong.

    *   Sense 5: condition of living / state of being alive.
    *   Sense 10: organic phenomenon.
    *   In many WordNet versions, these are very close. But the example for Sense 5 is a near-perfect match for the context.

    *   Sense 5: "the condition of living or the state of being alive"
    *   Sense 10: "the organic phenomenon that distinguishes living organisms from nonliving ones"
    *   If the text is about biochemistry and elements, it's discussing the *requirements* for the *state* of being alive.

    *   Wait, let me re-read the context one more time. "The find is important in the search for life beyond Earth... recognize life... extraterrestrial life... elements we think are absolutely necessary for life".
    *   The whole paragraph is about the *existence* of life (the phenomenon/organisms).
    *   If I have to choose the *single best* sense for the specific word `<t>life</t>` in the phrase "necessary for life", and Sense 5's example is "life depends on many chemical and physical processes", Sense 5 is the most direct fit.

    *   Sense 5: "the condition of living or the state of being alive"
    *   Sense 10: "the organic phenomenon that distinguishes living organisms from nonliving ones"
    *   Is there a subtle difference? "Condition/state" (5) vs "Phenomenon" (10).
    *   "Necessary for the state of being alive" vs "Necessary for the organic phenomenon".
    *   The example for Sense 5 is almost identical in meaning to the target sentence.

    *   Sense 5: "life depends on many chemical and physical processes"
    *   Target: "elements we think are absolutely necessary for life"
    *   This is a very strong match.

    *   Sense 10: "there is no life on the moon"
    *   This is more about the *presence* or *absence* of life.

    *   Sense 9: "the oceans are teeming with life"
    *   This is about the *abundance* of living things.

    *   Therefore, Sense 5 is the best fit for "necessary for life".

The study focuses on a microbe found on Earth. However, the announcement of a news conference to discuss it, which did not disclose details of the find, generated widespread speculation on the Internet that the report would disclose the discovery of extraterrestrial life. It didn't. The discovery "does show that in other planetary environments organisms might be able to use other elements to drive biochemistry and that the 'standard' set of elements we think are absolutely necessary for life might not be so fixed," commented Charles Cockell, professor at Planetary and Space <t>Sciences</t> Research Institute, Open University, in Milton Keynes, United Kingdom. Cockell was not part of the research team.

*   Target lemma: `discovery`
    *   Target surface form: `discovery`
    *   Context: "It wasn't a chance <t>discovery</t>. Felisa Wolfe-Simon of NASA's Astrobiology Institute, who led the study, targeted Mono Lake because it has high arsenic levels."
    *   Surrounding context: The text discusses a scientific find regarding organisms using different elements for biochemistry. It mentions a "find" and a "report" disclosing a "discovery of extraterrestrial life" (though it wasn't that). The specific sentence says "It wasn't a chance discovery," referring to the research result/finding.

    *   Sense 1: `something that is discovered` (The result/object of the discovery).
    *   Sense 2: `a productive insight` (breakthrough, find).
    *   Sense 3: `the act of discovering something` (find, uncovering).
    *   Sense 4: `(law) compulsory pretrial disclosure...` (Legal term).

    *   The sentence "It wasn't a chance discovery" refers to the process/event of finding the result.
    *   Wait, let's look closer. "It wasn't a chance discovery. Felisa Wolfe-Simon... targeted Mono Lake because it has high arsenic levels."
    *   This implies that the *act* of finding it wasn't accidental; it was targeted.
    *   However, "discovery" often refers to the *thing* found (Sense 1) or the *breakthrough* (Sense 2).
    *   Let's compare Sense 1 (the thing), Sense 2 (the insight/breakthrough), and Sense 3 (the act).
    *   "It wasn't a chance discovery" -> "The act of discovering it wasn't by chance" OR "The thing discovered wasn't found by chance."
    *   In scientific contexts, "a discovery" often refers to the breakthrough/finding itself (Sense 2).
    *   Let's re-read: "The discovery 'does show that in other planetary environments...'" (This refers to the finding/insight - Sense 2).
    *   "It wasn't a chance discovery." (This refers to the event/act of finding it).
    *   If I say "It was a chance discovery," I usually mean the *act* of finding it happened by accident.
    *   Let's look at the synonyms:
        *   Sense 2: breakthrough, find.
        *   Sense 3: find, uncovering.
    *   In "It wasn't a chance discovery," "discovery" is used as a noun describing the event.
    *   Let's check Sense 1: "something that is discovered".
    *   If the sentence is "It wasn't a chance discovery," it means the process of finding it was intentional. This points toward the *act* of discovering (Sense 3).
    *   However, in many corpora, "discovery" in "a chance discovery" refers to the *find* (the result of the act).
    *   Let's re-evaluate Sense 2 vs Sense 3.
    *   Sense 2: "a productive insight" (breakthrough).
    *   Sense 3: "the act of discovering something".
    *   "It wasn't a chance discovery" -> The *finding* of the result wasn't accidental.
    *   If we replace "discovery" with "find" (synonym for both 2 and 3): "It wasn't a chance find."
    *   If we replace it with "uncovering" (synonym for 3): "It wasn't a chance uncovering."
    *   If we replace it with "breakthrough" (synonym for 2): "It wasn't a chance breakthrough."
    *   The context "targeted Mono Lake because it has high arsenic levels" strongly emphasizes the *method* of finding, which relates to the *act* of discovery.

    *   Sense 1: The thing discovered.
    *   Sense 2: The insight/breakthrough.
    *   Sense 3: The act of discovering.
    *   "It wasn't a chance discovery" = The act of discovering it was not accidental.
    *   Let's look at the previous paragraph: "the report would disclose the discovery of extraterrestrial life." (Here, "discovery" is the thing/event).
    *   "The discovery 'does show that...'" (Here, "discovery" is the finding/insight - Sense 2).
    *   "It wasn't a chance discovery." (Here, it refers back to the same event/finding, but emphasizes the lack of "chance" in the process).

    *   Is "discovery" in "chance discovery" the *act* or the *thing*?
    *   Usually, "a chance discovery" refers to the event/act of finding something.
    *   Example: "The discovery of penicillin was a chance discovery." (The act of finding it was accidental).
    *   This aligns best with Sense 3: "the act of discovering something".

    *   Sense 1: something that is discovered.
    *   Sense 2: a productive insight.
    *   Sense 3: the act of discovering something.
    *   If the sentence is "It wasn't a chance discovery," it's describing the *nature of the event* (how it was found). This is the act of discovering.

    *   Wait, let me double-check Sense 2 again. "a productive insight | synonyms=breakthrough, find".
    *   And Sense 3: "the act of discovering something | synonyms=find, uncovering".
    *   In "It wasn't a chance discovery," the word "discovery" can be seen as the *result* (the find) or the *process* (the act).
    *   However, "chance" modifies the way it happened. "Chance" describes the *act* of discovering.
    *   Therefore, Sense 3 is the most precise.

    *   Sense 1: The object.
    *   Sense 2: The breakthrough/insight.
    *   Sense 3: The act/process.
    *   "It wasn't a chance discovery" -> The process of finding it was not accidental.
    *   This fits Sense 3.

Target lemma: study
Target surface form: study
Context:
It didn't. The discovery "does show that in other planetary environments organisms might be able to use other elements to drive biochemistry and that the 'standard' set of elements we think are absolutely necessary for life might not be so fixed," commented Charles Cockell, professor at Planetary and Space Sciences Research Institute, Open University, in Milton Keynes, United Kingdom. Cockell was not part of the research team. "This work is novel because it shows the substitution of one element for another in fundamental biochemistry and biochemical structure," added Cockell. It wasn't a chance discovery. Felisa Wolfe-Simon of NASA's Astrobiology Institute, who led the <t>study</t>, targeted Mono Lake because it has high arsenic levels.

    *   In scientific contexts, "leading a study" usually refers to leading the research project/investigation, which results in a "study" (the report/paper) or is the "study" (the investigation itself).
    *   Looking at the candidate senses:

        *   Sense 9: "a detailed critical inspection" (survey).
    *   Wait, let's re-evaluate. In common usage, "the study" often refers to the research project/investigation.
    *   Sense 2 (written document/report) is very close.
    *   Sense 9 (detailed critical inspection/survey) is also close.
    *   Let's look at the examples for Sense 2: "this accords with the recent study by Hill and Dale". This fits the scientific context perfectly.
    *   Let's look at Sense 9: "a detailed critical inspection". This is more like a survey or a review.
    *   In the context of "led the study," it refers to the research project/investigation. While Sense 2 says "written document," in scientific parlance, "the study" often metonymically refers to the entire research process and its resulting publication.

    *   Sense 10: No.

    *   "Felisa Wolfe-Simon... who led the study..."
    *   This refers to the scientific investigation. In WordNet, "study" as a scientific investigation is often mapped to the "written report" sense (Sense 2) or "detailed inspection" (Sense 9).
    *   Comparing Sense 2 ("written document describing the findings") and Sense 9 ("detailed critical inspection"), Sense 2 is the standard way "study" is used in scientific reporting (e.g., "a study showed that...").

    *   Sense 2: report, written report.
    *   Sense 9: survey.
    *   "Led the study" implies leading the research effort. The result of that effort is the "study" (the paper/report).

    *   Sense 2 is the most appropriate for a scientific study.

Target lemma: behavior
Target surface form: behavior
Context:
Cockell was not part of the research team. "This work is novel because it shows the substitution of one element for another in fundamental biochemistry and biochemical structure," added Cockell. It wasn't a chance discovery. Felisa Wolfe-Simon of NASA's Astrobiology Institute, who led the study, targeted Mono Lake because it has high arsenic levels. Arsenic and phosphorus are chemically similar, so she speculated that a microbe exposed to both might be able to substitute one for the other. "Arsenic is toxic mainly because its chemical <t>behavior</t> is so similar to that of phosphorus." "As a result, organisms have a hard time telling these elements apart."

"Arsenic is toxic mainly because its chemical behavior is so similar to that of phosphorus." "As a <t>result</t>, organisms have a hard time telling these elements apart." "But arsenic is different enough that it doesn't work as well as phosphorus, so it gets in there and sort of gums up the works of our biochemical machinery," explained Anbar.

*   Target lemma: `result`
    *   Target surface form: `result`
    *   Context: "Arsenic is toxic mainly because its chemical behavior is so similar to that of phosphorus." "As a <t>result</t>, organisms have a hard time telling these elements apart."
    *   Candidate senses:
        1.  `result%1:19:00::`: a phenomenon that follows and is caused by some previous phenomenon (synonyms: consequence, effect, outcome, event, issue, upshot).
        2.  `result%1:10:00::`: a statement that solves a problem or explains how to solve the problem (synonyms: solution, answer, resolution, solvent).
        3.  `result%1:10:01::`: the semantic role of the noun phrase whose referent exists only by virtue of the activity denoted by the verb in the clause (synonyms: resultant role).
        4.  `result%1:11:00::`: something that results (synonyms: resultant, final result, outcome, termination).

    *   The sentence is: "As a result, organisms have a hard time telling these elements apart."
    *   The preceding sentence is: "Arsenic is toxic mainly because its chemical behavior is so similar to that of phosphorus."
    *   The phrase "As a result" is a common idiomatic expression meaning "consequently" or "as a consequence of the previously mentioned fact."
    *   The "result" here is the fact that organisms have a hard time telling the elements apart, which is caused by the similarity in chemical behavior.

    *   Sense 1: "a phenomenon that follows and is caused by some previous phenomenon" (consequence, effect). This fits perfectly.
    *   Sense 2: "a statement that solves a problem" (solution, answer). This does not fit.
    *   Sense 3: "the semantic role of the noun phrase..." (linguistic term). This does not fit.
    *   Sense 4: "something that results" (resultant, final result). This is very similar to Sense 1, but Sense 1 specifically emphasizes the causal link ("caused by some previous phenomenon"), which is exactly what "As a result" signifies in this context. Sense 4 often refers to the end product or a score (e.g., "the results of the election").

    *   Sense 1 is the standard meaning for "As a result" (consequence/effect).
