Methodology: Astronomy
What it measures
Tests astronomy knowledge and understanding, including celestial objects, planetary science, astrophysics, and observational astronomy. Queries cover topics such as stars, planets, galaxies, cosmology, and astronomical phenomena.
Scoring & Criteria
Returns score 1.0 if the extracted answer exactly matches the expected answer letter (after normalization), otherwise 0.0. The system prompt requests answers in `<answer>X</answer>` format where X is a letter from the provided choices (A, B, C, D, etc.). The grader normalizes for models that include the full choice text instead of just the letter, or that violate the answer tag format from the system prompt. Only one answer is correct.
Evaluation Type: Multiple Choice
Grades multiple choice responses by exact string matching with normalization.
