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_xVcVg):
Calculate 8 - -2 - -3.

Question 1 (Question id: q_TzMEQ):
Calculate 3 - -7.



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

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_xVcVg": {"answer": 13, "answer_type": "integer"}, "q_TzMEQ": {"answer": 10, "answer_type": "integer", "additional_answer_info": {"half_answer": 5, "double_answer": 20}}}}
