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_JK49hOzw):
Solve for n: 35 - 18*n = 17 Respond with an integer.

Question 1 (Question id: q_wJdMiYa):
Calculate -3 + 7.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
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_JK49hOzw": {"answer": 1, "answer_type": "integer"}, "q_wJdMiYa": {"answer": 4, "answer_type": "integer", "half_answer": 2}}}
