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_5x8qdCf):
Calculate -3 * -3 + 1.

Question 1 (Question id: q_56g20E):
Calculate 1 - -7.

Question 2 (Question id: q_m088):
Solve for l: 20*l - 25 = 135 Respond with an integer.



Output JSON where all question ids are keys, omitting q_5x8qdCf.

Each key’s value must be an object holding an 'answer' field.
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_m088": {"answer": 8, "answer_type": "integer", "half_answer": 4}, "q_56g20E": {"answer": 8, "answer_type": "integer", "half_answer": 4}}}
