Target lemma: discovery
Target surface form: discovery
Context:
Six major elements have long been considered essential for life - carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. But the researchers found that the bacteria, discovered in Mono Lake, Calif., is able to continue to grow after substituting arsenic for phosphorus. "It makes you wonder what else is possible," said Ariel D. Anbar of Arizona State University, a co-author of the report. The find is important in the search for life beyond Earth because researchers need to be able to recognize life, to know what life looks like, Anbar said. 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 <t>discovery</t> of extraterrestrial life. It didn't.

*   Target lemma: `discovery`
    *   Target surface form: `discovery`
    *   Context: "...generated widespread speculation on the Internet that the report would disclose the <t>discovery</t> of extraterrestrial life."
    *   Candidate senses:
        1.  `discovery%1:04:00::`: the act of discovering something (process/action)
        2.  `discovery%1:10:00::`: something that is discovered (the result/object)
        3.  `discovery%1:09:00::`: a productive insight (breakthrough)
        4.  `discovery%1:10:01::`: (law) compulsory pretrial disclosure

    *   The sentence says: "...the report would disclose the discovery of extraterrestrial life."
    *   In this context, "discovery of extraterrestrial life" refers to the *finding* or the *existence* of extraterrestrial life that has been uncovered.
    *   Is it the *act* of discovering (sense 1) or the *thing* discovered (sense 2)?
    *   Usually, "the discovery of [something]" can be ambiguous between the act and the thing. However, in the context of "disclosing the discovery," it typically refers to the fact/finding that something exists (the result).
    *   Let's compare sense 1 (act) and sense 2 (something discovered).
        *   Sense 1: "the act of discovering something" (e.g., "The discovery of the new land took months.")
        *   Sense 2: "something that is discovered" (e.g., "The discovery of penicillin changed medicine.")
    *   In "the discovery of extraterrestrial life," the focus is on the *finding* itself (the fact that extraterrestrial life was found), which aligns better with "something that is discovered" (the result/entity).
    *   Sense 3 (productive insight/breakthrough) is close, but "discovery of extraterrestrial life" is more about the existence of the life form than a conceptual insight.
    *   Sense 4 (law) is irrelevant.

    *   "the report would disclose the discovery of extraterrestrial life."
    *   If you disclose a discovery, you are disclosing the *thing* that was found.
    *   Example: "The discovery of gold in California" -> The gold (the thing discovered) or the act of finding it? Usually, it's the event/fact of the find.
    *   WordNet's `discovery%1:10:00::` (something that is discovered) is the standard sense for the result of the process.

    *   Sense 1: act of discovering.
    *   Sense 2: something that is discovered.
    *   In "discovery of extraterrestrial life," the "discovery" is the object being disclosed. It refers to the finding/existence of the life. This fits sense 2 best.

    *   Wait, let me double-check. If I say "The discovery of America," is that the act or the thing? It's often the event.
    *   If I say "This discovery will change the world," I'm referring to the thing discovered (sense 2).
    *   If I say "The discovery of the ruins took years," I'm referring to the act (sense 1).
    *   In "disclose the discovery of extraterrestrial life," the report is disclosing the *fact/finding* (the thing discovered).

    *   Sense 1: act of discovering.
    *   Sense 2: something that is discovered.
    *   Sense 3: productive insight.
    *   The "discovery of extraterrestrial life" is the *thing* that was found.

    *   Sense 2: `discovery%1:10:00::` | definition=something that is discovered.
    *   This fits perfectly.

    *   Sense 1: act of discovering.
    *   Sense 2: something that is discovered.
    *   Sense 3: productive insight.
    *   Sense 4: legal.
    *   The context "disclose the discovery of extraterrestrial life" refers to the finding itself.

    *   Wait, let's look at sense 3 again: "a productive insight | synonyms=breakthrough, find".
    *   Is "the discovery of extraterrestrial life" a "breakthrough"? Yes. But is it primarily "something that is discovered"? Yes.
    *   Usually, "discovery of [X]" where X is a physical entity (like extraterrestrial life) maps to sense 2.

    *   Sense 1: act of discovering.
    *   Sense 2: something that is discovered.
    *   If the report discloses the *act* of discovering, it's about *how* it was found. If it discloses the *discovery*, it's about *what* was found. The context suggests the latter.

    *   Sense 2 is the most fitting.

    *   The sentence is: "The discovery 'does show that in other planetary environments organisms might be able to use other elements to drive biochemistry...'"
    *   The "discovery" refers to the finding of the microbe and the resulting scientific understanding/insight.
    *   Earlier in the text, it's referred to as "The find".
    *   Sense 1 (the act) doesn't fit as well as the result of the act.
    *   Sense 2 (something that is discovered) is a general term for the object found.
    *   Sense 3 (a productive insight/breakthrough/find) fits well because the discovery is not just the microbe itself, but the *implication* or *insight* it provides about biochemistry in other environments.
    *   Sense 4 (law) is completely irrelevant.

    *   Sense 2: "something that is discovered" (The microbe).
    *   Sense 3: "a productive insight" (The fact that other elements can drive biochemistry).
    *   The text says: "The discovery 'does show that...'" This phrasing suggests the discovery is the *finding* or *insight* that leads to a conclusion.
    *   Looking at the synonyms for Sense 3: "breakthrough, find". The text explicitly uses "The find is important..." earlier.
    *   While Sense 2 is a generic "thing discovered", Sense 3 captures the "scientific breakthrough/insight" aspect which is more precise for a scientific discovery that changes understanding.

    *   "The find is important..."
    *   "The discovery 'does show that...'"
    *   The "discovery" here is the scientific result/insight.
    *   Comparing Sense 2 (something discovered) vs Sense 3 (productive insight/breakthrough).
    *   In scientific contexts, a "discovery" that "shows" something is typically treated as a breakthrough or a productive insight (Sense 3).

    *   Sense 1: Act of discovering. (No)
    *   Sense 2: The thing discovered. (Possible, but less specific)
    *   Sense 3: Productive insight/breakthrough. (Best fit for "The discovery does show that...")
    *   Sense 4: Legal discovery. (No)

    *   Wait, let me re-read Sense 2 and 3.
    *   Sense 2: "something that is discovered"
    *   Sense 3: "a productive insight"
    *   If the "discovery" is the microbe, it's Sense 2. If the "discovery" is the realization/insight about biochemistry, it's Sense 3.
    *   The sentence "The discovery 'does show that...'" implies the discovery is the evidence/insight.
    *   Synonyms for Sense 3 include "find". The text uses "The find is important".

    *   Sense 3 is the most precise for a scientific discovery that provides a new understanding.

    *   Context: "...the 'standard' <t>set</t> of elements we think are absolutely necessary for life might not be so fixed..."
    *   Meaning: In this context, "set of elements" refers to a group of chemical elements (like carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur) that are typically considered essential for life.

    *   1: a group of things of the same kind that belong together and are so used (e.g., a set of books).

    *   12: (psychology) being temporarily ready to respond.
    *   13: electronic equipment (radio/TV).

    *   The phrase is "standard set of elements".
    *   This is a group of things (chemical elements) of the same kind (elements) that belong together (as the requirements for life).
    *   Sense 1 ("a group of things of the same kind that belong together") fits perfectly.
    *   Sense 2 ("mathematics... abstract collection") is too specialized for general scientific description here, although "set" in science often borrows from math. However, "a set of elements" in the context of biochemistry is more naturally a "group of things" (Sense 1) than a formal mathematical set (Sense 2).

    *   Sense 1: "a group of things of the same kind that belong together and are so used"

Target lemma: element
Target surface form: elements
Context:
"It makes you wonder what else is possible," said Ariel D. Anbar of Arizona State University, a co-author of the report. The find is important in the search for life beyond Earth because researchers need to be able to recognize life, to know what life looks like, Anbar said. 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 <t>elements</t> 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.

    *   Broader context: The text discusses the search for extraterrestrial life, microbes, biochemistry, and planetary environments.

    *   1: characteristic state or mode of living (e.g., social life) - No.
    *   2: experience of being alive/course of human events (e.g., complexities of life) - No.
    *   3: course of existence of an individual (e.g., new life in Australia) - No.

    *   6: period between birth and present - No.
    *   7: period from present until death - No.

    *   12: biography - No.
    *   13: motive for living - No.
    *   14: prison term - No.

    *   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 *phenomenon* of life to exist (biochemistry, organisms).
    *   Sense 10 ("living things collectively") refers to the *population* of organisms.
    *   Sense 11 ("the organic phenomenon that distinguishes living organisms from nonliving ones") refers to the *concept* or *biological process* of life itself.
    *   In the context of "elements necessary for life," it's talking about the biological phenomenon/process (biochemistry), not just a collection of organisms.

    *   Sense 11 example: "there is no life on the moon."
    *   Context: "search for life beyond Earth", "recognize life", "discovery of extraterrestrial life", "elements we think are absolutely necessary for life".
    *   All these point toward the biological phenomenon (Sense 11).

    *   Sense 4: "the condition of living or the state of being alive". This is more about the *state* of an entity.
    *   Sense 11: "the organic phenomenon that distinguishes living organisms from nonliving ones". This is the scientific/biological definition of life as a phenomenon.
    *   The context is scientific (biochemistry, planetary environments, microbes). Sense 11 fits the scientific context perfectly.

    *   Surrounding context: The text discusses a scientific study/discovery about a microbe and biochemistry. Charles Cockell (a professor) is commenting on the research team's findings.

    *   Sense 1: activity directed toward making or doing something (general activity).
    *   Sense 2: a product produced or accomplished through the effort or activity or agency of a person or thing (a specific piece of work, like a symphony or a scientific paper/study).

    *   Sense 7: total output of a writer or artist (oeuvre).

    *   The speaker (Cockell) says, "This work is novel because it shows..."
    *   "This work" refers to the research/study/discovery mentioned previously ("The study focuses on a microbe...", "the report would disclose the discovery...").
    *   In academic and scientific contexts, "this work" typically refers to the specific research project, paper, or study being discussed.
    *   Comparing Sense 1 and Sense 2:
        *   Sense 1 is the *activity* of working.
        *   Sense 2 is the *product* of that activity (the study, the paper, the discovery).
    *   "This work is novel" suggests the *result* or the *study itself* is novel, not the act of doing the research. Therefore, Sense 2 (a product produced or accomplished) fits best.

    *   Sense 2: "a product produced or accomplished through the effort or activity or agency of a person or thing". Examples: "it is not regarded as one of his more memorable works; the symphony was hailed as an ingenious work". A scientific study is a product of research effort.

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.

    *   Candidate senses:
        1.  `substitution%1:11:00::`: an event in which one thing is substituted for another (synonyms: permutation, transposition, replacement, switch; example: replacement of lost blood by a transfusion of donor blood).
        2.  `substitution%1:04:00::`: the act of putting one thing or person in the place of another (synonyms: exchange, commutation; example: he sent Smith in for Jones but the substitution came too late to help).

    *   The context describes a scientific discovery where one element is used instead of another in biochemistry.
    *   "the substitution of one element for another in fundamental biochemistry"
    *   This refers to the *fact* or *event* of one element replacing another in a chemical structure, rather than the *act* of a person consciously swapping one for another (like a coach making a substitution in a game or a manager replacing an employee).

    *   Sense 1: "an event in which one thing is substituted for another". Example: "replacement of lost blood by a transfusion of donor blood". This fits well with a biological/chemical process where one element takes the place of another.
    *   Sense 2: "the act of putting one thing or person in the place of another". Example: "he sent Smith in for Jones". This implies a deliberate action or a tactical change.

    *   The context is about a natural biochemical property ("organisms might be able to use other elements to drive biochemistry"). The "substitution" is a characteristic of the biochemistry, not a deliberate act performed by a person.
    *   Sense 1 (the event/occurrence of replacement) is a better fit for a scientific phenomenon than Sense 2 (the act of replacing).

    *   Sense 1: replacement, switch.
    *   Sense 2: exchange, commutation.
    *   "Replacement" (Sense 1) fits "substitution of one element for another" perfectly.

    *   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 biochemistry and organisms using different elements. 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 scientific result obtained from targeting Mono Lake.

    *   Sense 1: `discovery%1:04:00::` - the act of discovering something (process/action).
    *   Sense 2: `discovery%1:10:00::` - something that is discovered (the result/object).
    *   Sense 3: `discovery%1:09:00::` - a productive insight (breakthrough, find).
    *   Sense 4: `discovery%1:10:01::` - (law) compulsory pretrial disclosure.

    *   The sentence "It wasn't a chance discovery" refers to the scientific finding.
    *   Is it the *act* of discovering (Sense 1)? Or the *thing* discovered (Sense 2)? Or a *breakthrough/insight* (Sense 3)?
    *   "Chance discovery" usually refers to a serendipitous find.
    *   Looking at the context: "The discovery 'does show that in other planetary environments organisms might be able to use other elements...'" This suggests the *result* or the *finding* itself.
    *   Comparing Sense 2 (something that is discovered) and Sense 3 (a productive insight/breakthrough).
    *   In scientific contexts, a "discovery" is often a "find" or a "breakthrough."
    *   Sense 2 is very general ("something that is discovered").
    *   Sense 3 is more specific to a "productive insight" or "breakthrough."
    *   The text says "This work is novel because it shows the substitution of one element for another...". This points towards a breakthrough or a significant find.
    *   However, "chance discovery" is a common collocation. Does it refer to the *act* (Sense 1) or the *thing* (Sense 2/3)?
    *   "It wasn't a chance discovery" means the finding didn't happen by accident; it was targeted. This refers to the event/result of the research.
    *   Let's re-evaluate Sense 2 vs Sense 3.
        *   Sense 2: something that is discovered.
        *   Sense 3: a productive insight (synonyms: breakthrough, find).
    *   The text uses the word "find" earlier: "...did not disclose details of the find...".
    *   Sense 3 lists "find" as a synonym.
    *   The discovery is described as "novel" and showing something fundamental about biochemistry. This fits "productive insight" or "breakthrough" better than just "something that is discovered."

    *   Sense 1: Act of discovering. (Less likely, though "chance discovery" can refer to the act).
    *   Sense 2: The thing discovered. (Possible).
    *   Sense 3: A productive insight/breakthrough. (Very likely given the scientific context and the synonym "find").

    Wait, let's look at the sentence again: "It wasn't a chance discovery. Felisa Wolfe-Simon... targeted Mono Lake..."
    This implies the *process* of finding it wasn't accidental. If it refers to the process, Sense 1 (the act of discovering) might be the best.
    But "discovery" in "chance discovery" often refers to the result that was found by chance.
    Example: "The discovery of penicillin was a chance discovery." (The result was a discovery, and the act was a chance discovery).

    Let's look at the synonyms for Sense 3: "breakthrough, find".
    The text says: "...did not disclose details of the find...".
    The text says: "The discovery 'does show that...'"
    The text says: "This work is novel..."

    If we compare "the act of discovering" (1) vs "something that is discovered" (2) vs "a productive insight" (3).
    "It wasn't a chance discovery" -> The finding was not accidental.
    Usually, "a discovery" in this context refers to the scientific result.
    Between 2 and 3, 3 is more specific to scientific breakthroughs.

    Let's check WordNet's typical usage.
    `discovery%1:09:00` (productive insight) is often used for scientific breakthroughs.
    `discovery%1:10:00` (something discovered) is more generic.

    The context emphasizes the novelty and the scientific implication ("shows the substitution of one element for another in fundamental biochemistry"). This strongly aligns with "productive insight" or "breakthrough".

    *   Sense 1: act of discovering.
    *   Sense 2: something discovered.
    *   Sense 3: productive insight/breakthrough.
    *   Sense 4: legal disclosure.

    "It wasn't a chance discovery" -> The result was not found by accident.
    The "discovery" here is the scientific finding.
    Is a scientific finding a "something that is discovered" (2) or a "productive insight" (3)?
    In most WSD tasks for scientific contexts, "discovery" meaning a breakthrough is mapped to the "productive insight" sense.

    Let's double-check the synonyms for Sense 3: "breakthrough, find".
    The text explicitly uses "find" earlier.

    Therefore, Sense 3 is the most precise.

    *   "led the study" -> led the research project.
    *   Comparing Sense 1 and Sense 3:
        *   Sense 1 (detailed critical inspection) fits the *process* of the research.
        *   Sense 3 (written document) fits the *result* of the research.
    *   Usually, "leading a study" refers to leading the investigation/research project.
    *   Let's check if "detailed critical inspection" (Sense 1) is the best fit for a scientific research project.
    *   Actually, in many WSD datasets (like SemCor), "study" in the sense of a scientific research project is often mapped to the "detailed critical inspection" or "report" sense depending on the specific nuance.
    *   Let's look at the synonyms: Sense 1 (survey), Sense 3 (report).
    *   "led the survey" vs "led the report". "Led the study" (the research project) is closer to "led the investigation/inspection".
    *   However, in common usage, "the study" often refers to the published paper.
    *   Let's re-read Sense 1: "a detailed critical inspection".
    *   Let's re-read Sense 3: "a written document describing the findings".
    *   If she "led the study," she led the process of investigation.
    *   Let's look at the examples for Sense 3: "this accords with the recent study by Hill and Dale". This is exactly how scientific studies are referenced.
    *   Let's look at the examples for Sense 1: (no examples provided, but synonym is "survey").
    *   In the context of "led the study," it refers to the research project. A research project is a detailed critical inspection/investigation.
    *   Wait, let me double-check WordNet's structure for "study".
    *   study%1:10:00 is "a written document describing the findings of some individual or group".
    *   study%1:04:00 is "a detailed critical inspection".
    *   In scientific literature, "the study" is almost always used interchangeably for the research process and the resulting paper.
    *   However, "led the study" strongly implies the process of conducting the research.
    *   Let's compare:
        *   "The study showed that..." (Sense 3 - the report)
        *   "She led the study." (Sense 1 - the investigation)
    *   Actually, looking at how these are typically tagged in corpora:
        *   "a study of [something]" -> Sense 1 (inspection/investigation).
        *   "the study published in Nature" -> Sense 3 (report).
    *   "led the study" -> led the investigation.
    *   Let's re-examine Sense 1: "a detailed critical inspection". This fits "investigation".
    *   Let's re-examine Sense 3: "a written document describing the findings".
    *   If she led the *document*, that's less common than leading the *investigation*.
    *   Therefore, Sense 1 is a better fit for the act of leading the research.

    *   Wait, let me search for "led the study" in WSD contexts.
    *   Often, "study" in "led the study" is treated as the research project.
    *   Is "detailed critical inspection" the best fit for "research project"?
    *   Yes, among the choices provided.

    *   Sense 1: detailed critical inspection.
    *   Sense 3: written document describing findings.
    *   "led the study" -> led the investigation/inspection.
    *   If the sentence was "The study concluded that...", Sense 3 would be very strong.
    *   "led the study" refers to the leadership of the research effort.

    *   Sense 1: study%1:04:00 (detailed critical inspection)
    *   Sense 3: study%1:10:00 (written document)
    *   In the context of "led the study", the "study" is the research project/investigation.
    *   "Detailed critical inspection" is a synonym for "investigation" or "survey".
    *   "Written document" is a synonym for "report".
    *   You lead an investigation, you write/publish a report.
    *   Therefore, Sense 1 is more appropriate for "led the study".

    *   Wait, let me think again. In many scientific contexts, "the study" is used as a shorthand for the entire project, including the paper.
    *   Let's look at the synonyms again.
    *   Sense 1: survey.
    *   Sense 3: report, written report.
    *   "led the survey" vs "led the report".
    *   "led the survey" makes more sense.

    *   Let's double-check if there are any other options.
    *   Sense 2: learning/understanding (no)
    *   Sense 4: mental absorption (no)
    *   Sense 5: room (no)
    *   Sense 6: branch of knowledge (no)
    *   Sense 7: sketch (no)
    *   Sense 8: cogitation (no)
    *   Sense 9: quick learner (no)
    *   Sense 10: musical composition (no)

    *   So it's between 1 and 3.
    *   "led the study" -> led the investigation.
    *   Investigation = detailed critical inspection.
    *   Report = written document.
    *   Conclusion: Sense 1.

    *   *Self-Correction*: Let me search for "led the study" in a few more examples.
    *   "The study, led by [Name], found that..."
    *   In this common phrasing, "the study" refers to the research project.
    *   Is a research project a "detailed critical inspection"? Yes.
    *   Is it a "written document"? The *result* is, but the *leading* is of the process.

    *   Let's check Sense 1 again: "a detailed critical inspection".
    *   Let's check Sense 3 again: "a written document describing the findings".
    *   If I say "I am conducting a study," I am doing a detailed critical inspection.
    *   If I say "I am reading a study," I am reading a written document.
    *   "led the study" is closer to "conducting a study".

    *   Final choice: Sense 1.

    *   *Wait*, let me re-read the context one more time.
    *   "Felisa Wolfe-Simon... who led the study, targeted Mono Lake..."
    *   "Targeted Mono Lake" is an action taken during the *process* of the research.
    *   This confirms that "study" here refers to the process/investigation, not the final document.
    *   Process/Investigation = Sense 1.

Target lemma: arsenic
Target surface form: arsenic
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 study, targeted Mono Lake because it has high <t>arsenic</t> 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.

Candidate senses:
1. sense_key=arsenic%1:27:01:: | definition=a white powdered poisonous trioxide of arsenic; used in manufacturing glass and as a pesticide (rat poison) and weed killer | synonyms=arsenic trioxide, arsenous anhydride, arsenous oxide, white arsenic, ratsbane
2. sense_key=arsenic%1:27:00:: | definition=a very poisonous metallic element that has three allotropic forms; arsenic and arsenic compounds are used as herbicides and insecticides and various alloys; found in arsenopyrite and orpiment and realgar | synonyms=As, atomic number 33

*   Target lemma: `arsenic`
    *   Target surface form: `arsenic`
    *   Context: "...targeted Mono Lake because it has high <t>arsenic</t> 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."
    *   Candidate senses:
        1.  `arsenic%1:27:01::`: a white powdered poisonous trioxide of arsenic (a specific compound).
        2.  `arsenic%1:27:00::`: a very poisonous metallic element (the element As, atomic number 33).

    *   The text mentions "high arsenic levels" in Mono Lake.
    *   It compares arsenic to phosphorus ("Arsenic and phosphorus are chemically similar").
    *   Phosphorus is a chemical element.
    *   The discussion is about "substitution of one element for another in fundamental biochemistry".
    *   This strongly indicates that "arsenic" refers to the chemical element (As), not specifically to arsenic trioxide.

    *   Sense 1 is a specific compound (arsenic trioxide).
    *   Sense 2 is the element (As).
    *   The context explicitly refers to it as an "element" and compares it to another element (phosphorus).

    *   Sense 2 is the correct fit.
