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_BzEMXY):
Solve for q: 17*q + 10 = 231 Respond with an integer.

Question 1 (Question id: q_fGaNxgo):
Calculate 8 + -4 / 2.



Output JSON where all question ids are keys, omitting q_fGaNxgo.

The value for each key should be an object that contains the answer in the field 'answer'.
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 last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_BzEMXY": {"answer": 13}}}
