### Task

You are given a question, a set of options, and context, which may come from multiple sources.

Your task is to:

1. **Select the correct answer from the provided options** based on the information in the context.
2. Provide a **rationale** explaining why the selected option is correct, grounded explicitly in the given context.
3. Provide a **confidence score** between 0.0 and 1.0, indicating how certain you are about your selection.

### Guidelines

- Base your answer and rationale **only on the given context** — do not use outside knowledge.
- Your answer must be **exactly one of the provided options**.
- Your answer must be a **single sentence** (no line breaks).
- The rationale may consist of multiple sentences.
- The rationale should:
  - Explicitly reference relevant information from the context.
  - Explain why the selected option is supported.
  - Avoid introducing any information not present in the context.
- The score should reflect your confidence in the correctness of your answer:
  - **1.0** = absolutely certain  
  - **0.0** = no idea  

- Some context passages may be structured passages that list multiple time-stamped factual statements and an explicit Relations section.
- The real world evolves over time, and factual statements may be updated, contradicted by other statements, or later found to be incorrect; therefore, not all statements in the context passages should be assumed to be simultaneously valid.
- Relations, when present, are intended to help interpret such situations and may include:
  - updates: a later statement provides revised information about an earlier statement, but the correct statement depends on the date relevant to the question; do not assume that the most recent statement is always correct.
  - contradicts: statements that refer to the same timeframe or state but provide incompatible facts, meaning they cannot both be true.
  - supports: statements that provide evidence for or reinforce another statement.
- Because the context passages are automatically extracted, they may contain noise, inaccuracies, or misleading information.
- When answering, reason carefully about which statements are applicable and reliable, using both their timestamps and any stated relations, rather than treating statements as independent facts.
- If multiple statements are relevant but inconsistent, prefer the statement that best matches the question’s date and is most strongly supported by other statements.

### Output Format

Provide the output as exactly one JSON object:

{{
  "rationale": "[explanation grounded in the context]",
  "answer": "[your answer]",
  "score": [score between 0.0 and 1.0]
}}

Do not include Markdown code fences or text outside the JSON object.

Example:

{{
  "rationale": "The context states that aspirin is commonly prescribed for pain relief, fever reduction, and inflammatory control.",
  "answer": "Aspirin is used to treat pain, fever, and inflammation.",
  "score": 0.95
}}

### Context

{contexts_prompt}

### Input

{test_case_prompt}

Now, based on the context above, select the best answer from the options and provide a rationale, answer, and confidence score.
Provide the output in the format specified above.
