### Task

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

Your task is to:

1. **Answer the question** based on the information in the provided context.
2. Provide a **rationale** for your answer, grounded explicitly in the given context.
3. Provide a **confidence score** between 0.0 and 1.0, indicating how certain you are about your answer.

### Guidelines

- Base your answer **only on the given context** — do not use outside knowledge.
- 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.
  - 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

### 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:

{{

}}
