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_3MyI):
Calculate 3 * 1.

Question 1 (Question id: q_C53n):
Solve for m: -30*m - 2 = -542 Respond with an integer.



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

The value for each key should be an object that contains the answer in the field 'answer'.
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.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_3MyI": {"answer": 3, "answer_type": "integer"}, "q_C53n": {"answer": 18, "answer_type": "integer", "half_answer": 9}}}
