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_3rXk):
Find the value of c in the equation: 10 - 16*c = -150 Respond with an integer.

Question 1 (Question id: q_gYQrh):
Calculate 9 - 0 - 0.

Question 2 (Question id: q_ZHOjzKhv):
Calculate -4 * -3.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.

{"ground_truth": {"q_3rXk": {"answer": 10, "answer_type": "integer", "half_answer": 5}, "q_gYQrh": {"answer": 9, "answer_type": "integer"}, "q_ZHOjzKhv": {"answer": 12, "answer_type": "integer", "half_answer": 6}}}
