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_UaKeKp):
How many times does the letter "a" appear in the text: "whom I was"? Respond with an integer.

Question 1 (Question id: q_c5mw9a):
Calculate ( 6 + 9 ).



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.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
Add 'num_questions_answered' showing how many questions you answered.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_UaKeKp": {"answer": 1}, "q_c5mw9a": {"answer": 15}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2, "questions_with_integer_answers": ["q_UaKeKp", "q_c5mw9a"]}}}
