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_2afshqug):
How many times does the letter "t" appear in the text: "at the call"? Respond with an integer.

Question 1 (Question id: q_DdVY):
Calculate 5 * ( 7 + 1 ).



Produce a JSON object whose top-level keys are the question ids.

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.

Now provide the result JSON using the described format.

{"ground_truth": {"q_2afshqug": {"answer": 2, "half_answer": 1}, "q_DdVY": {"answer": 40, "half_answer": 20}}}
