Here is a set of basic questions producing integer or string outputs. Answer them and format the result precisely with the JSON instructions provided:

Question 0 (Question id: q_rzNK):
Find the value of o in the equation: 42*o = 378 Respond with an integer.

Question 1 (Question id: q_PkFk0e):
Calculate ( 6 * 5 ).



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.
• num_questions_answered: count of questions present in your JSON.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_rzNK": {"answer": 9}, "q_PkFk0e": {"answer": 30, "half_answer": 15}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2, "questions_with_integer_answers": ["q_rzNK", "q_PkFk0e"]}}}
