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_1hOqGs0):
Calculate -9 + 2 - -7.

Question 1 (Question id: q_0csniYOm):
Find the value of i in the equation: 20*i + 7 = 187 Respond with an integer.



Return a JSON with each question id as a key.

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_1hOqGs0": {"answer": 0, "answer_type": "integer", "half_answer": 0}, "q_0csniYOm": {"answer": 9, "answer_type": "integer"}}}
