Target lemma: element
Target surface form: element
Context:
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 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 <t>element</t> for another in fundamental biochemistry and biochemical structure," added Cockell. It wasn't a chance discovery.

raw_output:
To determine the best indexed sense for the target word "element" in the given context, let's analyze the context and the provided candidate senses.

The context is about a scientific discovery related to microbes and biochemistry, where a professor, Charles Cockell, comments on the significance of the discovery. He mentions that the study shows organisms might use other "elements" to drive biochemistry, indicating a discussion about the basic substances or components involved in biochemical processes.

Let's examine the candidate senses:

1. **sense_key=element%1:09:00::** - This sense refers to an abstract part of something. While "element" can be used abstractly, the context here is more about biochemical or chemical aspects, not abstract concepts like character traits or components of a musical composition.

2. **sense_key=element%1:06:00::** - This refers to an artifact that is part of a composite entity. The context doesn't discuss artifacts or parts of a system in this sense; it's more focused on biochemical substances.

3. **sense_key=element%1:27:00::** - This defines "element" as any of the more than 100 known substances that cannot be separated into simpler substances and constitute all matter. The context fits this definition well, as it discusses using "other elements" in biochemistry, implying a reference to chemical elements.

4. **sense_key=element%1:15:00::** - This refers to the most favorable environment for a plant or animal. The context doesn't discuss environments or habitats.

5. **sense_key=element%1:27:01::** - This is about the four substances thought in ancient and medieval cosmology to constitute the universe. While historically relevant, this doesn't fit the modern biochemical context.

6. **sense_key=element%1:26:00::** - This refers to being in the situation where one is happiest and most effective. The context doesn't relate to personal effectiveness or happiness.

7. **sense_key=element%1:25:00::** - This is a geometric definition related to generating a cylinder or cone, which doesn't fit the biochemical context.

Given the context and the definitions, the most appropriate sense is **3**, as it directly relates to "chemical element," which is relevant to the discussion about biochemistry and the substitution of one element for another in biochemical processes.

To determine the best indexed sense for the target word "phosphorus" in the given context, let's analyze the information provided.

The context discusses a scientific study related to astrobiology, specifically about microbes substituting arsenic for another element in their biochemistry. The element in question is "phosphorus." The text mentions that arsenic and phosphorus are chemically similar, which is the reason arsenic is toxic.

Now, let's examine the candidate senses:

1. The first sense defines phosphorus as "a multivalent nonmetallic element of the nitrogen family that occurs commonly in inorganic phosphate rocks and as organic phosphates in all living cells; is highly reactive and occurs in several allotropic forms." The synonyms provided are P and atomic number 15. This definition aligns with the context, as it discusses the biochemical role of phosphorus and its similarity to arsenic.

2. The second sense defines phosphorus as "a planet (usually Venus) seen just before sunrise in the eastern sky," with synonyms morning star, daystar, and Lucifer. This definition is unrelated to the biochemical or chemical context provided.

Given the context, which involves biochemistry and the chemical properties of elements, the most relevant definition is the first one. It correctly identifies phosphorus as a chemical element involved in biochemistry, which is directly related to the discussion about substituting arsenic for phosphorus in microbial biochemistry.

raw_output:
To determine the best indexed sense for the target word "possibility" in the given context, let's analyze the context and the provided candidate senses.

The context discusses a scientific finding related to a microbe that can live with arsenic instead of phosphorus, raising the "possibility" that a life form using arsenic could occur naturally elsewhere. The sentence implies a potential or prospect based on the discovery made.

Let's examine the candidate senses:

1. **sense_key=possibility%1:09:03::** - This sense refers to "a future prospect or potential." The example given is "this room has great possibilities." While this sense could potentially fit, the context is more about a theoretical or potential outcome rather than a direct prospect or potential in the immediate or tangible sense.

2. **sense_key=possibility%1:26:00::** - This sense is defined as "capability of existing or happening or being true." The synonym given is "possibleness," and an example is "there is a possibility that his sense of smell has been impaired." This sense aligns closely with the context, as it discusses the capability or potential truth of a life form using arsenic occurring naturally.

3. **sense_key=possibility%1:09:00::** - This refers to "a tentative insight into the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena." The synonyms are "hypothesis" and "theory." While the context is scientific, the term "possibility" here is not directly referring to a hypothesis or theory but rather to a potential outcome or situation.

4. **sense_key=possibility%1:09:01::** - This sense is "a possible alternative." The synonyms given are "possible action" and "opening," with an example being "bankruptcy is always a possibility." This sense doesn't directly fit the context, as the "possibility" discussed is not an alternative action or option but rather a potential scenario or state of being.

Given the context and the definitions, the most appropriate sense is **2. sense_key=possibility%1:26:00::**, as it directly relates to the capability or potential of something being true or happening, which aligns with the discussion of a life form using arsenic potentially occurring naturally.

Therefore, the best indexed sense for the target word "possibility" is: {"sense_index": 2}
