Target lemma: month
Target surface form: months
Context:
In all three studies, the main measure of effectiveness was how long the patients survived. What benefit has Alimta shown during the studies? Alimta increased the survival time of patients with malignant pleural mesothelioma. Patients receiving Alimta and cisplatin survived for an average of 12.1 months, compared with 9.3 months in those receiving cisplatin alone. In the treatment of patients with non-small cell lung cancer, Alimta was as effective as the comparators. In patients who had received chemotherapy in the past, the average survival time was 8.3 <t>months</t> with Alimta, compared with 7.9 months with docetaxel. In patients who had not received chemotherapy in the past, the average survival time was 10.3 months in both groups.

1.  **Analyze the target word and context:**
    *   Target lemma: `month`
    *   Target surface form: `months`
    *   Context snippet: "Patients receiving Alimta and cisplatin survived for an average of 12.1 months, compared with 9.3 months in those receiving cisplatin alone. In the treatment of patients with non-small cell lung cancer, Alimta was as effective as the comparators. In patients who had received chemotherapy in the past, the average survival time was 8.3 <t>months</t> with Alimta, compared with 7.9 months with docetaxel. In patients who had not received chemotherapy in the past, the average survival time was 10.3 months in both groups."
    *   The word `months` is used in the context of "average survival time" (e.g., "12.1 months," "9.3 months," "8.3 months").

2.  **Analyze the candidate senses:**
    *   **Sense 1 (month%1:28:01):** Definition: "one of the twelve divisions of the calendar year." Synonyms: "calendar month." Example: "he paid the bill last month." (Refers to January, February, etc.)
    *   **Sense 2 (month%1:28:00):** Definition: "a time unit of approximately 30 days." Examples: "he was given a month to pay the bill." (Refers to a duration of time.)

3.  **Determine the best fit:**
    *   The context refers to "survival time" measured in "months." This is a measure of duration (e.g., 12.1 units of time).
    *   Sense 1 refers specifically to calendar months (Jan, Feb, Mar). This is incorrect for measuring survival duration.
    *   Sense 2 refers to a general time unit of approximately 30 days, which perfectly matches the usage of "months" as a unit of duration for survival time.

4.  **Conclusion:** Sense 2 is the best fit.

5.  **Format the output:** The instruction requires a JSON object with the sense index. Since the candidates are numbered 1 and 2, the index is 2. (Wait, the prompt asks for `{"sense_index": 3}` in the example, but I only have 2 candidates. I must assume the numbering in the prompt is sequential, so Sense 2 corresponds to index 2.)

*Self-Correction/Review:* The prompt structure is slightly confusing regarding the final output format if I only have two candidates but the example shows `{"sense_index": 3}`. I will stick to the logical mapping: Sense 1 = Index 1, Sense 2 = Index 2.

*Final check of the instruction:* "Return only a JSON object exactly like {"sense_index": 3}." I will use the index corresponding to Sense 2.

The user wants me to perform Word Sense Disambiguation for the target word "compared" (the past participle of "compare") based on the provided context.

Context analysis:
The sentence containing the target word is: "In patients who had received chemotherapy in the past, the average survival time was 8.3 months with Alimta, <t>compared</t> with 7.9 months with docetaxel."

The structure is: [Survival time with Alimta] compared with [Survival time with docetaxel].
This structure is used to highlight a difference or similarity between two measured values (8.3 months vs 7.9 months).

Candidate senses:
1. sense_key=compare%2:31:00:: | definition=examine and note the similarities or differences of | examples=John compared his haircut to his friend's; We compared notes after we had both seen the movie
2. sense_key=compare%2:42:00:: | definition=be comparable | examples=This car does not compare with our line of Mercedes
3. sense_key=compare%2:31:01:: | definition=consider or describe as similar, equal, or analogous | synonyms=liken, equate | examples=We can compare the Han dynasty to the Romans; You cannot equate success in financial matters with greed
4. sense_key=compare%2:32:00:: | definition=to form the comparative or superlative form on an adjective or adverb

Evaluation:
The context is comparing two survival times (8.3 months vs 7.9 months).

Sense 1 (examine and note similarities or differences): This fits well. The sentence is noting the difference between the two groups' survival times.
Sense 2 (be comparable): This is a state of being, not the action of comparing the data points. Less likely.
Sense 3 (consider or describe as similar, equal, or analogous): This also fits, as the comparison is describing the relationship between the two data points. The synonyms (liken, equate) suggest drawing a parallel or contrast.
Sense 4 (form the comparative/superlative form): This is grammatical usage (e.g., *more* effective), not the meaning used here. Incorrect.

Distinguishing between Sense 1 and Sense 3:
Sense 1 focuses on the *act* of examining differences/similarities.
Sense 3 focuses on the *result* of the comparison (describing them as similar/analogous).

In the phrase "compared with," the function is to draw a contrast or relationship between the two measured values. Both Sense 1 and Sense 3 are strong candidates.

Let's look closer at the examples and definitions.
Sense 1: "John compared his haircut to his friend's." (Action of examination/note-taking).
Sense 3: "We can compare the Han dynasty to the Romans." (Describing them as analogous/similar).

When used in scientific/statistical reporting ("X compared with Y"), the primary function is to note the difference or relationship between the two entities. Sense 1, "examine and note the similarities or differences of," captures this observational/analytical function perfectly. Sense 3 is slightly more abstract (likening concepts), while Sense 1 is more concrete (noting differences in measured data).

Given the context of survival times (8.3 months vs 7.9 months), the most precise fit is noting the difference/relationship between the two measured outcomes.

Therefore, Sense 1 is the best fit.

2. sense_key=month%1:28:00:: | definition=a time unit of approximately 30 days | examples=he was given a month to pay the bill

Analysis:
The context discusses "survival time" (e.g., "survived for an average of 12.1 months"). The numbers (12.1, 9.3, 8.3, 7.9, 10.3) are used as measurements of duration.

Sense 1 (calendar month): Refers to specific divisions of the year (January, February, etc.). This is not relevant to measuring survival duration in a medical study.
Sense 2 (a time unit of approximately 30 days): Refers to a general unit of time used for measurement (duration). This perfectly matches the usage in the context ("12.1 months" of survival time).

Conclusion: Sense 2 is the correct sense.

1.  **Analyze the target word and context:**
    *   Target lemma: patient
    *   Target surface form: patients
    *   Context: "Alimta increased the survival time of patients with malignant pleural mesothelioma. Patients receiving Alimta and cisplatin survived for an average of 12.1 months, compared with 9.3 months in those receiving cisplatin alone. In the treatment of patients with non-small cell lung cancer, Alimta was as effective as the comparators.

In patients who had not received chemotherapy in the past, the average survival time was 10.3 months in both groups. However, in both studies, patients whose cancer was not affecting squamous cells had longer survival times if they received Alimta than if they received the comparator."

2.  **Analyze the candidate senses:**
    *   **Sense 1 (patient%1:18:00):** Definition: "a person who requires medical care." Example: "the number of emergency patients has grown rapidly."
    *   **Sense 2 (patient%1:10:00):** Definition: "the semantic role of an entity that is not the agent but is directly involved in or affected by the happening denoted by the verb in the clause." Synonyms: "affected role, patient role."

3.  **Determine the meaning in context:**
    *   The context discusses medical studies, cancer (malignant pleural mesothelioma, non-small cell lung cancer), survival times, and treatments (Alimta, cisplatin, docetaxel).
    *   "Patients" refers to the individuals undergoing these medical treatments and studies.
    *   This usage clearly refers to the *person* receiving medical care.

4.  **Match the context meaning to the senses:**
    *   Sense 1 ("a person who requires medical care") perfectly matches the usage of "patients" in this medical context.
    *   Sense 2 ("the semantic role... affected by the happening") refers to a grammatical/semantic function (like 'patient' in a passive sentence structure), not the actual person. This is incorrect.

5.  **Select the best sense:** Sense 1.

6.  **Format the output:** The instruction requires returning only a JSON object with the sense index. Since the provided candidates are numbered 1 and 2, and Sense 1 is the correct choice, the index is 1. (Wait, the prompt asks for the index of the chosen sense, but the provided candidates are not numbered in the final output format, only in the internal list. I must ensure I map the chosen sense to the required JSON structure.)

    *   Candidate 1 = Sense 1 (Correct)
    *   Candidate 2 = Sense 2 (Incorrect)

    The required output format is `{"sense_index": 3}` (implying the index is 3, which is confusing since I only have 2 candidates). Assuming the prompt intends for me to use the index corresponding to the chosen sense among the provided list (1 or 2), I will use 1.

    *Self-Correction/Re-evaluation:* The example output uses `{"sense_index": 3}`. If I only have two candidates, I must assume the numbering in the prompt is arbitrary or that I should select the index corresponding to the chosen sense (Sense 1). I will proceed with the index 1, as it is the correct semantic match.

Target word: survival (specifically the instance marked `<t>survival</t>`)

Candidate senses:
1. sense_key=survival%1:26:00:: | definition=a state of surviving; remaining alive | synonyms=endurance
2. sense_key=survival%1:22:00:: | definition=a natural process resulting in the evolution of organisms best adapted to the environment | synonyms=survival of the fittest, natural selection, selection
3. sense_key=survival%1:04:00:: | definition=something that survives

Analysis:
The context discusses medical studies, patients, cancer (malignant pleural mesothelioma, non-small cell lung cancer), chemotherapy, and "survival time."
The phrase is "the average survival time was 10.3 months in both groups."

1. Sense 1: "a state of surviving; remaining alive" (Synonyms: endurance). This fits perfectly with the medical context of how long patients remain alive. "Survival time" refers to the duration of life.
2. Sense 2: "a natural process resulting in the evolution of organisms..." This refers to biological evolution (e.g., natural selection). This is irrelevant to clinical trial data on patient longevity.
3. Sense 3: "something that survives." This is a very general sense, often referring to an object or entity that persists (e.g., "the survival of the ancient manuscript"). While technically related, Sense 1 is much more specific and accurate when paired with "time" in a medical context.

Conclusion: Sense 1 is the best fit, as it refers to the state of remaining alive over a period of time, which is the standard meaning of "survival time" in oncology studies.

Mapping to the required output format:
The best sense is Sense 1.
The required output is a JSON object with the sense index.

Context:
What benefit has Alimta shown during the studies? Alimta increased the survival time of patients with malignant pleural mesothelioma. Patients receiving Alimta and cisplatin survived for an average of 12.1 months, compared with 9.3 months in those receiving cisplatin alone. In the treatment of patients with non-small cell lung cancer, Alimta was as effective as the comparators. In patients who had received chemotherapy in the past, the average survival time was 8.3 months with Alimta, compared with 7.9 months with docetaxel. In patients who had not received chemotherapy in the past, the average survival <t>time</t> was 10.3 months in both groups.

The user wants me to perform Word Sense Disambiguation for the target word "time" in the given context.

Context: "In patients who had not received chemotherapy in the past, the average survival <t>time</t> was 10.3 months in both groups."

Target word: time
Contextual meaning: The duration of survival (10.3 months).

Candidate senses analysis:
1. time%1:11:00: an instance or single occasion for some event (e.g., "this time he succeeded"). Not relevant to survival duration.
2. time%1:28:05: a period of time considered as a resource under your control and sufficient to accomplish something (e.g., "take time to smell the roses"). Not relevant to survival duration.
3. time%1:28:00: an indefinite period (usually marked by specific attributes or activities) (e.g., "he waited a long time; the time of year for planting"). This sense covers general periods, which includes survival duration.
4. time%1:28:06: a suitable moment (e.g., "it is time to go"). Not relevant.
5. time%1:03:00: the continuum of experience in which events pass from the future through the present to the past. Too abstract, not specific to a measured duration like "10.3 months".
6. time%1:11:01: a person's experience on a particular occasion. Not relevant.
7. time%1:28:03: a reading of a point in time as given by a clock (e.g., "the time is 10 o'clock"). Not relevant.
8. time%1:28:04: the fourth coordinate that is required... (Physics concept). Not relevant.
9. time%1:07:01: rhythm as given by division into parts of equal duration. Not relevant.
10. time%1:28:01: the period of time a prisoner is imprisoned. Too specific (imprisonment).

The context refers to "average survival time" measured in months (10.3 months). This is a specific, measured duration or period.

Sense 3: "an indefinite period (usually marked by specific attributes or activities)" fits well. Survival time is a period marked by the activity (life/survival) and measured by duration.

Sense 2: "a period of time considered as a resource under your control..." While survival time is a period, the focus here is on the measured duration, not its utility as a resource.

Sense 3 is the most general and appropriate fit for a measured duration like "survival time."

Therefore, sense_key=time%1:28:00:: is the best choice.

Analysis:
The context discusses "survival time" (e.g., "survived for an average of 12.1 months," "average survival time was 8.3 months").
The numbers (12.1, 9.3, 8.3, 7.9, 10.3) are used as units of duration for survival.

Sense 1 (calendar month): Refers to January, February, etc. This does not fit the context of survival duration measured in decimals (12.1 months).
Sense 2 (a time unit of approximately 30 days): This refers to a general unit of time used to measure duration, which perfectly matches the context of survival time measurement.

Conclusion: Sense 2 is the correct sense.

2. **Sense 1 (any number of entities considered as a unit):** This fits perfectly. Patients are entities, and they are being categorized into units (groups) for comparison.
3. **Sense 2 (chemistry):** This is clearly irrelevant. The context is medical/clinical trials.

"Alimta increased the survival time of patients with malignant pleural mesothelioma.

In contrast, patients whose cancer was affecting squamous cells had shorter survival times if they received Alimta."

Target word: However

Analysis of the context surrounding "However":
The preceding sentences discuss survival times in different patient groups (those who received past chemotherapy vs. those who didn't).
The sentence starting with "However" introduces a new, overarching finding that applies to *both* studies mentioned previously. This new finding contrasts or shifts the focus from the specific survival time comparisons to a general pattern based on the type of cancer cells affected (squamous cells vs. non-squamous cells).

Let's examine the candidate senses:

1. sense_key=however%4:02:00:: | definition=despite anything to the contrary (usually following a concession) | synonyms=nevertheless, withal, still, yet, all the same, even so | This suggests a contrast or contradiction to the immediately preceding statement. While there is a shift in focus, the new statement isn't strictly contradicting the previous data points; it's adding a general principle that applies across the data.
2. sense_key=however%4:02:04:: | definition=by contrast; on the other hand | examples=the first part was easy; the second, however, took hours | This suggests a direct opposition or shift to an alternative viewpoint/topic. The new statement ("in both studies, patients whose cancer was not affecting squamous cells had longer survival times...") presents a different, more nuanced finding compared to the previous specific comparisons. This fits well.
3. sense_key=however%4:02:02:: | definition=to whatever degree or extent | examples=The results, however general, are important; they have begun, however reluctantly, to acknowledge the legitimacy of some of the opposition's concerns | This is an adverbial modifier of degree (e.g., "however quickly"). This does not fit the context.
4. sense_key=however%4:02:01:: | definition=in whatever way or manner | examples=Victory, however it was brought about, was sweet; however he did it, it was very clever | This is also an adverbial modifier of manner. This does not fit the context.

Comparing Sense 1 and Sense 2:
Sense 1 (despite anything to the contrary/nevertheless) implies a concession followed by a surprising outcome.
Sense 2 (by contrast/on the other hand) implies a shift to a different, often opposing, point of view or comparison.

The transition here is from specific survival time data (e.g., 12.1 vs 9.3 months) to a general finding about cancer type (squamous vs non-squamous). This is a shift in focus and a presentation of a contrasting pattern that applies across the data sets. "By contrast" (Sense 2) captures this shift in focus and presentation of a different pattern better than "nevertheless" (Sense 1), which usually implies a direct contradiction to the immediately preceding clause.

The subsequent sentence reinforces this contrast: "In contrast, patients whose cancer was affecting squamous cells had shorter survival times if they received Alimta." This explicit use of "In contrast" confirms that the transition marked by "However" is meant to introduce a contrasting pattern or finding.

Therefore, Sense 2 is the best fit.

Context: "However, in both <t>studies</t>, patients whose cancer was not affecting squamous cells had longer survival times if they received Alimta than if they received the comparator. In contrast, patients whose cancer was affecting squamous cells had shorter survival times if they received Alimta."

The context is a scientific/medical paper discussing clinical trials and survival times of patients treated with Alimta and cisplatin. The phrase "in both studies" refers to the research conducted.

Let's examine the candidate senses:

1. **sense_key=study%1:04:00::** | definition=a detailed critical inspection | synonyms=survey. (Fits the idea of a research investigation/trial.)
2. **sense_key=study%1:09:03::** | definition=applying the mind to learning and understanding a subject (especially by reading) | synonyms=work. (Incorrect. Refers to academic learning.)
3. **sense_key=study%1:10:00::** | definition=a written document describing the findings of some individual or group | synonyms=report, written report. (Fits the idea of a research paper/report, which is the output of a study.)
4. **sense_key=study%1:09:04::** | definition=a state of deep mental absorption. (Incorrect. Refers to concentration.)
5. **sense_key=study%1:06:00::** | definition=a room used for reading and writing and studying. (Incorrect. Refers to a physical location.)
6. **sense_key=study%1:09:02::** | definition=a branch of knowledge | synonyms=discipline, subject, subject area, subject field, field, field of study. (Incorrect. Refers to a field of science, e.g., oncology.)
7. **sense_key=study%1:06:01::** | definition=preliminary drawing for later elaboration | synonyms=sketch. (Incorrect. Refers to art/design.)
8. **sense_key=study%1:09:01::** | definition=attentive consideration and meditation | synonyms=cogitation. (Incorrect. Refers to thought process.)
9. **sense_key=study%1:18:00::** | definition=someone who memorizes quickly and easily. (Incorrect. Refers to a person.)
10. **sense_key=study%1:10:01::** | definition=a composition intended to develop one aspect of the performer's technique. (Incorrect. Refers to music.)

The context refers to clinical research trials. Both sense 1 (detailed critical inspection/survey) and sense 3 (written document describing findings/report) are plausible in a scientific context.

*   Sense 1: "In both studies [investigations/trials]..."
*   Sense 3: "In both studies [reports/papers]..."

In scientific writing, "studies" often refers to the entire research effort (Sense 1), but it can also refer to the resulting published paper (Sense 3). Since the text is summarizing findings ("had longer survival times"), it refers to the completed research efforts.

Sense 1 (detailed critical inspection/survey) is the most encompassing definition for a clinical trial or research investigation.
Sense 3 (written document describing the findings) is also very strong, as the findings are being discussed.

Let's re-evaluate the nuance. When researchers say "in both studies," they usually mean "in both research investigations/trials."

Sense 1: "a detailed critical inspection" (Synonym: survey). This perfectly matches a clinical trial.
Sense 3: "a written document describing the findings." While the findings are in a document, the word "study" itself refers to the process or the investigation, not just the document.

Therefore, Sense 1 is the most accurate representation of the intended meaning in this scientific context.

Wait, I must choose the single best indexed sense. Let's check if there is a stronger fit.

If I choose Sense 1 (detailed critical inspection), it covers the entire research process.
If I choose Sense 3 (written document), it covers the output.

In academic discourse, especially when comparing results ("had longer survival times"), "studies" refers to the research projects themselves.

Let's stick with Sense 1 as the primary meaning of a research "study."

Sense 1: study%1:04:00:: | definition=a detailed critical inspection | synonyms=survey

Final check: The context is about comparing results from two research efforts. "In both studies" means "In both research investigations." This aligns best with Sense 1.

2. `sense_key=patient%1:10:00`: definition=the semantic role of an entity that is not the agent but is directly involved in or affected by the happening denoted by the verb in the clause | synonyms=affected role, patient role

Evaluation:
Sense 1: "a person who requires medical care." This perfectly matches the context (people with cancer receiving treatment).
Sense 2: "the semantic role of an entity..." This is a grammatical/linguistic concept (the patient role in semantics), not the referent itself.

Conclusion: Sense 1 is the correct interpretation.

The required output format is a JSON object with the sense index. Since the candidates are numbered 1 and 2, I must choose the index corresponding to Sense 1.

Target lemma: cancer
Target surface form: cancer
Context:
Alimta increased the survival time of patients with malignant pleural mesothelioma. Patients receiving Alimta and cisplatin survived for an average of 12.1 months, compared with 9.3 months in those receiving cisplatin alone. In the treatment of patients with non-small cell lung cancer, Alimta was as effective as the comparators. In patients who had received chemotherapy in the past, the average survival time was 8.3 months with Alimta, compared with 7.9 months with docetaxel. In patients who had not received chemotherapy in the past, the average survival time was 10.3 months in both groups. However, in both studies, patients whose <t>cancer</t> was not affecting squamous cells had longer survival times if they received Alimta than if they received the comparator. In contrast, patients whose cancer was affecting squamous cells had shorter survival times if they received Alimta.

5. sense_key=cancer%1:05:00:: | definition=type genus of the family Cancridae | synonyms=genus Cancer

Analysis:
The context discusses medical studies, survival times, chemotherapy (Alimta, cisplatin, docetaxel), and specific cell types (squamous cells).
The phrase "patients whose cancer was not affecting squamous cells" clearly refers to a disease or condition affecting cells, not an astrological sign, a constellation, or a genus of crustaceans.

Sense 1: "any malignant growth or tumor caused by abnormal and uncontrolled cell division..." This perfectly matches the medical context (malignant disease, cell effects, survival times).
Sense 2, 3, 4, 5: These relate to astrology or zoology (Crab/Cancer sign/genus) and are irrelevant to the medical discussion.

Therefore, Sense 1 is the correct choice.

The user wants me to perform Word Sense Disambiguation for the word "affecting" (the present participle of "affect") in the given context.

Context: "However, in both studies, patients whose cancer was not <t>affecting</t> squamous cells had longer survival times if they received Alimta than if they received the comparator. In contrast, patients whose cancer was affecting squamous cells had shorter survival times if they received Alimta."

Target word: affecting (from the verb 'affect')

Analysis of the context:
The sentence discusses cancer and its relationship with "squamous cells."
"Patients whose cancer was not affecting squamous cells..."
"patients whose cancer was affecting squamous cells..."
Here, "affecting" describes the action of the cancer relative to the cells. Cancer is an agent that acts upon or influences the cells.

Evaluation of candidate senses:

1. sense_key=affect%2:30:00:: | definition=have an effect upon | synonyms=impact, bear upon, bear on, touch on, touch | Examples: Will the new rules affect me?
    * This sense means to influence or impact. Cancer influencing cells fits this definition well.

2. sense_key=affect%2:29:00:: | definition=act physically on; have an effect upon | Examples: the medicine affects my heart rate
    * This is a more physical/direct action sense. While cancer is a physical process, the relationship described (cancer *on* cells) is about biological influence/impact, which aligns closely with sense 1.

3. sense_key=affect%2:42:00:: | definition=connect closely and often incriminatingly | synonyms=involve, regard | Examples: This new ruling affects your business
    * This sense relates to involvement or relevance (e.g., a legal ruling affecting a business). This is too abstract/legalistic for the biological context of cancer and cells.

4. sense_key=affect%2:32:00:: | definition=make believe with the intent to deceive | synonyms=feign, sham, pretend, dissemble | Examples: He feigned that he was ill; He shammed a headache
    * This is the psychological/deceptive sense. Irrelevant.

5. sense_key=affect%2:37:00:: | definition=have an emotional or cognitive impact upon | synonyms=impress, move, strike | Examples: This child impressed me as unusually mature; This behavior struck me as odd
    * This is the emotional/cognitive sense. Irrelevant.

Comparison between Sense 1 and Sense 2:
Sense 1: "have an effect upon" (General influence/impact).
Sense 2: "act physically on; have an effect upon" (Direct physical action).

In the context of cancer affecting cells, the relationship is one of biological influence or impact. Both senses are plausible, but Sense 1 ("have an effect upon") is the most general and accurate description of how a disease process (cancer) influences the state or behavior of cells. Sense 2 emphasizes the physical action, which might be too narrow, although cancer is physical. Since the core meaning is about the *influence* of the cancer on the cells, Sense 1 is the best fit.

Let's re-examine the phrasing: "cancer was affecting squamous cells." This means the cancer is influencing or impacting those cells.

Sense 1: "have an effect upon" -> Cancer has an effect upon the cells. (Best fit)
Sense 2: "act physically on" -> Cancer acts physically on the cells. (Plausible, but Sense 1 covers the biological influence more broadly).

I choose Sense 1.

The user wants me to perform Word Sense Disambiguation for the word "times" in the given context.
The target lemma is "time", and the surface form is "times".
The context is: "However, in both studies, patients whose cancer was not affecting squamous cells had longer survival <t>times</t> if they received Alimta than if they received the comparator. In contrast, patients whose cancer was affecting squamous cells had shorter survival times if they received Alimta."

The phrase is "survival times". This refers to the duration of survival.

Let's analyze the candidate senses:

1. sense_key=time%1:11:00: an instance or single occasion for some event. (e.g., "he called four times"). This refers to countable occurrences, not duration.
2. sense_key=time%1:28:05: a period of time considered as a resource under your control and sufficient to accomplish something. (e.g., "I didn't have time to finish"). This relates to available duration/resource.
3. sense_key=time%1:28:00: an indefinite period (usually marked by specific attributes or activities). (e.g., "he waited a long time; the time of year for planting"). This refers to a span or duration.
4. sense_key=time%1:28:06: a suitable moment. (e.g., "it is time to go"). This is a specific point in time.
5. sense_key=time%1:03:00: the continuum of experience in which events pass from the future through the present to the past. This is abstract/philosophical time.
6. sense_key=time%1:11:01: a person's experience on a particular occasion. This is experiential time.
7. sense_key=time%1:28:03: a reading of a point in time as given by a clock. This is clock time.
8. sense_key=time%1:28:04: the fourth coordinate that is required... to specify a physical event. This is physics/relativity time.
9. sense_key=time%1:07:01: rhythm as given by division into parts of equal duration. This is metrical time.
10. sense_key=time%1:28:01: the period of time a prisoner is imprisoned. This is a specific type of duration.

The context discusses "survival times" in a medical study. Survival time is a measure of duration—how long something lasts.

Sense 3: "an indefinite period (usually marked by specific attributes or activities)". This perfectly matches the concept of a duration, like "survival time."

Sense 2: "a period of time considered as a resource under your control". While survival time is a period, Sense 3 is a more general and accurate description of a measured duration in this context, whereas Sense 2 implies a resource management perspective.

Sense 10 is too specific (imprisonment).

Sense 3 is the best fit for describing a measured span of existence or duration, which is what "survival times" represents.

Therefore, I choose sense_key=time%1:28:00.

In <t>contrast</t>, patients whose cancer was affecting squamous cells had shorter survival times if they received Alimta."

Target word: contrast

Analysis of the context surrounding the target word:
The preceding sentence establishes a pattern:
"patients whose cancer was not affecting squamous cells had longer survival times if they received Alimta than if they received the comparator."
The target sentence then introduces a contrasting finding:
"In contrast, patients whose cancer was affecting squamous cells had shorter survival times if they received Alimta."

The word "contrast" here is used as a preposition or introductory phrase meaning "on the other hand" or "in opposition to what was just stated." It signals a difference or opposition between two groups (those whose cancer was not affecting squamous cells vs. those whose cancer was affecting squamous cells).

Evaluation of candidate senses:

1. sense_key=contrast%1:24:00:: | definition=the opposition or dissimilarity of things that are compared; , | synonyms=direct contrast | examples=in contrast to; by contrast
    * This sense perfectly matches the usage. The sentence is setting up a comparison/opposition ("In contrast, [Group B] behaved differently from [Group A]").

2. sense_key=contrast%1:04:00:: | definition=the act of distinguishing by comparing differences
    * This is a general definition of the action, but sense 1 captures the specific idiomatic usage ("in contrast") much better.

3. sense_key=contrast%1:09:01:: | definition=a conceptual separation or distinction | synonyms=line, dividing line, demarcation | examples=there is a narrow line between sanity and insanity
    * This relates to conceptual boundaries, not the comparative opposition used here.

4. sense_key=contrast%1:09:00:: | definition=the perceptual effect of the juxtaposition of very different colors
    * This is related to visual perception (color theory). Irrelevant.

5. sense_key=contrast%1:07:00:: | definition=the range of optical density and tone on a photographic negative or print (or the extent to which adjacent areas on a television screen differ in brightness)
    * This is related to photography/display technology. Irrelevant.

Conclusion: Sense 1 is the best fit, as it covers the meaning of opposition or dissimilarity used when drawing a comparison ("In contrast, ...").

[User]
Target lemma: patient
Target surface form: patients
Context:
Patients receiving Alimta and cisplatin survived for an average of 12.1 months, compared with 9.3 months in those receiving cisplatin alone. In the treatment of patients with non-small cell lung cancer, Alimta was as effective as the comparators. In patients who had received chemotherapy in the past, the average survival time was 8.3 months with Alimta, compared with 7.9 months with docetaxel. In patients who had not received chemotherapy in the past, the average survival time was 10.3 months in both groups. However, in both studies, patients whose cancer was not affecting squamous cells had longer survival times if they received Alimta than if they received the comparator. In contrast, <t>patients</t> whose cancer was affecting squamous cells had shorter survival times if they received Alimta.

Candidate senses:
1. sense_key=patient%1:18:00:: | definition=a person who requires medical care | examples=the number of emergency patients has grown rapidly
2. sense_key=patient%1:10:00:: | definition=the semantic role of an entity that is not the agent but is directly involved in or affected by the happening denoted by the verb in the clause | synonyms=affected role, patient role

Instructions:
1. Choose the single best indexed sense for the target word in context.
2. WordNet glosses are schematic; use the context, synonyms, and examples together.
3. Do not answer with a WordNet sense key.
4. Return only a JSON object exactly like {"sense_index": 3}.

1.  **Analyze the target word and context:**
    *   Target lemma: patient
    *   Target surface form: patients
    *   Context: "Patients receiving Alimta and cisplatin survived for an average of 12.1 months, compared with 9.3 months in those receiving cisplatin alone. In the treatment of patients with non-small cell lung cancer, Alimta was as effective as the comparators. In patients who had received chemotherapy in the past, the average survival time was 8.3 months with Alimta, compared with 7.9 months with docetaxel. In patients who had not received chemotherapy in the past, the average survival time was 10.3 months in both groups. However, in both studies, patients whose cancer was not affecting squamous cells had longer survival times if they received Alimta than if they received the comparator. In contrast, <t>patients</t> whose cancer was affecting squamous cells had shorter survival times if they received Alimta."
    *   The context is entirely medical, discussing cancer treatment (Alimta, cisplatin, docetaxel), survival times, and specific groups of people defined by their medical condition (non-small cell lung cancer, squamous cells).

2.  **Analyze the candidate senses:**
    *   **Sense 1:** `sense_key=patient%1:18:00:: | definition=a person who requires medical care | examples=the number of emergency patients has grown rapidly`
        *   This definition perfectly matches the usage in the context (people receiving chemotherapy/treatment for cancer).
    *   **Sense 2:** `sense_key=patient%1:10:00:: | definition=the semantic role of an entity that is not the agent but is directly involved in or affected by the happening denoted by the verb in the clause | synonyms=affected role, patient role`
        *   This is a linguistic/syntactic definition (semantic role). It does not refer to a person or entity in the real world, but rather a grammatical function. This is clearly incorrect in this medical context.

3.  **Determine the best sense:**
    *   Sense 1 is the only relevant and accurate interpretation of "patients" in this medical text.

4.  **Format the output:**
    *   The instruction requires returning a JSON object with the sense index.
    *   Sense 1 corresponds to index 1. (Assuming the provided list is indexed starting from 1).

5.  **Final check:** The context refers to individuals undergoing medical treatment for cancer. Sense 1 defines "a person who requires medical care." This is the correct choice.
