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_HPFLTa):
Calculate -9 - -2 - -8.

Question 1 (Question id: q_EIWatN1o):
Calculate 4 + 8 * 8.



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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:
Include 'num_questions_asked' to record the total number of questions presented.
Record the answered-question count in the field 'num_questions_answered'.

Now provide the result JSON using the described format.

{"ground_truth": {"q_HPFLTa": {"answer": 1}, "q_EIWatN1o": {"answer": 68, "additional_answer_info": {"half_answer": 34, "double_answer": 136}}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2}}}
