Target lemma: organism
Target surface form: organisms
Context:
"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 behavior is so similar to that of phosphorus." "As a result, <t>organisms</t> 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.

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 behavior is so similar to that of phosphorus." "As a result, 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. The researchers collected the bacteria known as GFAJ-1 and exposed it to increasing concentrations of arsenic, which it was able to adapt to and grow. The microbe does grow better on phosphorus, but showing that it can live with arsenic instead raises the <t>possibility</t> that a life form using arsenic could occur naturally, either elsewhere on Earth or on another planet or moon where arsenic is more common. Jamie S. Foster, an assistant professor of microbiology at the University of Florida, said the idea that arsenic could be substituted for phosphorus isn't new, but there has never been example where it was shown to work.

*   Target word: "possibility"
    *   Context: "...showing that it can live with arsenic instead raises the <t>possibility</t> that a life form using arsenic could occur naturally, either elsewhere on Earth or on another planet or moon where arsenic is more common."
    *   Meaning: The fact that the microbe can live with arsenic suggests that it is *possible* (capable of happening/existing) that arsenic-based life forms exist or could exist.

    *   Sense 1: "a tentative insight into the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena" (Synonyms: hypothesis, theory).
    *   Sense 2: "a future prospect or potential" (Example: "this room has great possibilities").
    *   Sense 3: "capability of existing or happening or being true" (Synonyms: possibleness).
    *   Sense 4: "a possible alternative" (Synonyms: possible action, opening).

    *   The sentence says "raises the possibility that a life form using arsenic could occur naturally".
    *   This is describing the *capability* of such a life form existing or happening.
    *   Sense 1 (hypothesis/theory) is close, but "possibility" here is used in the sense of "the chance/possibleness that X is true".
    *   Sense 3 ("capability of existing or happening or being true") fits perfectly. "Raises the possibility that [clause]" is a standard construction for sense 3.
    *   Sense 2 is about potential/prospects (like a room's potential).
    *   Sense 4 is about an alternative option/action.

    *   "raises the possibility that..." $\rightarrow$ "raises the chance/possibleness that..."
    *   This aligns with Sense 3.

    *   The text compares arsenic to phosphorus. Phosphorus is a chemical element.
    *   It mentions "these elements" referring to arsenic and phosphorus.
    *   It discusses the possibility of a "life form using arsenic," which refers to the element itself as a building block, not specifically the trioxide compound.
    *   The context is clearly about the chemical element (As).

    *   Sense 1 is the element (As, atomic number 33).
    *   Sense 2 is a specific compound (arsenic trioxide).

    *   The context refers to the element. Therefore, Sense 1 is the correct choice.

    *   Context: The text discusses arsenic's chemical behavior compared to phosphorus, its role in biochemical machinery, bacteria (GFAJ-1) adapting to it, and the possibility of life forms using it instead of phosphorus. It mentions it as an "element" and discusses its prevalence on early Earth and other planets.
    *   Candidate Senses:
        1.  `arsenic%1:27:00::`: A very poisonous metallic element (atomic number 33).
        2.  `arsenic%1:27:01::`: A white powdered poisonous trioxide of arsenic (arsenic trioxide).

    *   The text explicitly refers to arsenic as an "element" ("telling these elements apart").
    *   It compares it to phosphorus (another element).
    *   It discusses its presence on Earth and other planets as a fundamental building block for potential life forms.
    *   Sense 1 describes the element (As, atomic number 33).
    *   Sense 2 describes a specific compound (arsenic trioxide).

    *   The context clearly refers to the chemical element, not specifically to the trioxide compound.

    *   Sense 1 is the correct match.

Target lemma: phosphorus
Target surface form: phosphorus
Context:
"Arsenic is toxic mainly because its chemical behavior is so similar to that of phosphorus." "As a result, 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. The researchers collected the bacteria known as GFAJ-1 and exposed it to increasing concentrations of arsenic, which it was able to adapt to and grow. The microbe does grow better on phosphorus, but showing that it can live with arsenic instead raises the possibility that a life form using arsenic could occur naturally, either elsewhere on Earth or on another planet or moon where arsenic is more common. Jamie S. Foster, an assistant professor of microbiology at the University of Florida, said the idea that arsenic could be substituted for <t>phosphorus</t> isn't new, but there has never been example where it was shown to work. Arsenic was more common in the early times on Earth, she said, so researchers have speculated that early life forms might have used it.

    *   Context: "...Jamie S. Foster... said the idea that arsenic could be substituted for phosphorus isn't new, but there has never been <t>example</t> where it was shown to work."
    *   Meaning: In this context, "example" refers to a specific occurrence or case where the substitution of arsenic for phosphorus was actually demonstrated to work.

    *   Sense 1: "an item of information that is typical of a class or group" (illustration, instance, representative).
    *   Sense 2: "a task performed or problem solved in order to develop skill or understanding" (exercise).
    *   Sense 3: "an occurrence of something" (case, instance).
    *   Sense 4: "punishment intended as a warning to others" (deterrent example, lesson).
    *   Sense 5: "a representative form or pattern" (model).
    *   Sense 6: "something to be imitated" (exemplar, model).

    *   The sentence says "there has never been [an] example where it was shown to work."
    *   This means there has never been a *case* or an *occurrence* of this happening.
    *   Sense 1 (typical item of information) is close, but Sense 3 (occurrence/case) fits better when talking about whether something has ever happened in reality ("shown to work").
    *   Let's compare Sense 1 and Sense 3:
        *   Sense 1: "this patient provides a typical example of the syndrome" (illustrating a class).
        *   Sense 3: "it was a case of bad judgment; another instance occurred yesterday" (an occurrence).
    *   In the context "there has never been [an] example where it was shown to work," the speaker is saying there is no recorded *instance* or *case* of it working. This aligns perfectly with Sense 3.

    *   Sense 1: Typical item of information.
    *   Sense 3: Occurrence of something.
    *   The context is about the existence of a specific event/finding (an occurrence), not necessarily a "typical" illustration of a class.

    *   Sense 3 is the best fit.

        *   `way%1:07:01` (manner): the way in which something is done.
    *   "Ways to form life" -> "Methods to form life" (Sense 4) or "The manner in which life forms" (Sense 6).
    *   The contrast "not just how life formed on early Earth" suggests that "how" (manner/mode) is the key.
    *   However, "ways to [do something]" usually points to the means/method.
    *   Let's look at the synonyms for Sense 4: means, agency.
    *   Let's look at the synonyms for Sense 6: manner, mode, style, fashion.
    *   "Other modes of forming life" sounds plausible. "Other means of forming life" also sounds plausible.
    *   Usually, "ways to [verb]" is interpreted as "methods" (Sense 4).
    *   Let's re-read: "there could be other ways to form life". This means other chemical pathways or mechanisms.
    *   Sense 4: "how a result is obtained or an end is achieved". The result is "life". The "way" is the chemical process.
    *   Sense 6: "how something is done or how it happens".
    *   Comparing "means" vs "manner". "Means" is often the tool or method. "Manner" is the way it's performed.
    *   In scientific contexts, "ways to [achieve X]" usually refers to the method/means.

    *   Sense 4: `way%1:04:01` - "how a result is obtained or an end is achieved" (means, agency).
    *   Sense 6: `way%1:07:01` - "how something is done or how it happens" (manner, mode, style, fashion).
    *   "Ways to form life" -> The "end" is "life". The "way" is the process/method. This fits Sense 4 well.
    *   "How life formed" (the contrast) fits Sense 6 well.
    *   The sentence says "other ways to form life, not just how life formed". This suggests "ways" and "how" are being used similarly.
    *   If "how" = manner (Sense 6), then "ways" = manner (Sense 6).
    *   Let's check if "ways to [verb]" is typically Sense 4 or 6.
    *   "Ways to lose weight" -> methods (Sense 4).
    *   "Ways to solve a problem" -> methods (Sense 4).
    *   "Ways to form life" -> methods/mechanisms (Sense 4).

    *   Sense 4: means, agency.
    *   Sense 6: manner, mode, style, fashion.
    *   "Other means to form life" vs "Other modes to form life".
    *   "Means" is more common for "ways to [verb]".

    *   Wait, let me look at Sense 6 again: "how something is done or how it happens".
    *   "Ways to form life" = "How life is formed".
    *   This is a tough one. Let's look at the examples for Sense 6 again: "her dignified manner", "his rapid manner of talking". These are very specific to *style*.
    *   Sense 4 examples: "a means of control", "an example is the best agency of instruction". These are about *how a result is obtained*.
    *   "Forming life" is the result. The "way" is the method. This aligns better with Sense 4.

    *   Sense 4: `way%1:04:01` (means)
    *   Sense 6: `way%1:07:01` (manner)
    *   In many WSD datasets (like SemCor), "ways to [do something]" is often mapped to the "means/method" sense.

    *   "there could be other ways to form life"
    *   "ways" = methods/means.
    *   Sense 4: "how a result is obtained or an end is achieved".
    *   Result = life.
    *   Way = the chemical process (arsenic vs phosphorus).
    *   This fits perfectly.

Target lemma: life
Target surface form: life
Context:
"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. The researchers collected the bacteria known as GFAJ-1 and exposed it to increasing concentrations of arsenic, which it was able to adapt to and grow. The microbe does grow better on phosphorus, but showing that it can live with arsenic instead raises the possibility that a life form using arsenic could occur naturally, either elsewhere on Earth or on another planet or moon where arsenic is more common. Jamie S. Foster, an assistant professor of microbiology at the University of Florida, said the idea that arsenic could be substituted for phosphorus isn't new, but there has never been example where it was shown to work. Arsenic was more common in the early times on Earth, she said, so researchers have speculated that early life forms might have used it. "It does suggest that that there could be other ways to form <t>life</t>, not just how life formed on early Earth," said Foster, who was not part of Wolfe-Simon's research team. The research was supported by NASA, the Department of Energy and the National Institutes of Health.

    *   3: condition of living or state of being alive (e.g., while there's life there's hope) - Possible, but more about the *state*.
    *   4: course of existence of an individual (e.g., new life in Australia) - No.
    *   5: motive for living (e.g., pottery was his life) - No.
    *   6: a living person (e.g., saved a life) - No.
    *   7: living things collectively (e.g., oceans are teeming with life) - Possible.
    *   8: experience of being alive/human events (e.g., complexities of life) - No.
    *   9: period during which something is functional (e.g., battery life) - No.
    *   10: prison term (e.g., life sentence) - No.
    *   11: the organic phenomenon that distinguishes living organisms from nonliving ones (e.g., no life on the moon) - Very strong candidate.
    *   12: biography (e.g., life story) - No.
    *   13: animation and energy (e.g., give life to it) - No.
    *   14: period from present until death (e.g., emperor for life) - No.

    *   Sense 3: "the condition of living or the state of being alive"
    *   Sense 7: "living things collectively"
    *   Sense 11: "the organic phenomenon that distinguishes living organisms from nonliving ones"

    *   The context is about the *origin* and *nature* of life (biochemical machinery, arsenic vs. phosphorus, "ways to form life").
    *   "Ways to form life" refers to the biological/chemical process of creating living organisms.
    *   Sense 11 ("the organic phenomenon that distinguishes living organisms from nonliving ones") fits perfectly with the scientific discussion of abiogenesis (how life forms) and the search for extraterrestrial life.
    *   Sense 7 ("living things collectively") is more about the *presence* of organisms (e.g., "life in the ocean").
    *   Sense 3 ("the condition of living") is more about the *state* of being alive.

    *   The sentence "there could be other ways to form life" refers to the biological phenomenon/process of life itself. Sense 11 is the most precise fit for this scientific context.
