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_XFwxU):
Calculate -1 * ( -3 / 1 ).

Question 1 (Question id: q_fl7ru):
Solve for a: 520*a = 9880 Respond with an integer.



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.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.

Now provide the result JSON using the described format.

{"ground_truth": {"q_XFwxU": {"answer": 3, "answer_type": "integer"}, "q_fl7ru": {"answer": 19, "answer_type": "integer"}}}
