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_BTBwl4):
Calculate ( 5 + 5 ) / 10.

Question 1 (Question id: q_PjKIAY):
Calculate 6 + -3 + -3.



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.

Now provide the result JSON using the described format.

{"ground_truth": {"q_BTBwl4": {"answer": 1}, "q_PjKIAY": {"answer": 0, "additional_answer_info": {"half_answer": 0, "double_answer": 0}}, "global_metadata": {"num_questions_asked": 2}}}
