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_tXUe):
Calculate -7 + -6 * -9.

Question 1 (Question id: q_B6YF17F):
Calculate 7 + -3.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.

Now provide the result JSON using the described format.

{"ground_truth": {"q_tXUe": {"answer": 47}, "q_B6YF17F": {"answer": 4, "additional_answer_info": {"half_answer": 2, "double_answer": 8}}, "global_metadata": {"num_questions_asked": 2}}}
