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_wg3EDI):
Calculate ( 4 - -8 ).

Question 1 (Question id: q_5COV):
Calculate 7 / 7 + 5.

Question 2 (Question id: q_RyTYdtk):
Find the value of t in the equation: 11*t + 1 = 111 Respond with an integer.



Output JSON where all question ids are keys, omitting q_5COV.

For every question id, supply an object whose 'answer' field stores the solution.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_RyTYdtk": {"answer": 10, "half_answer": 5}, "q_wg3EDI": {"answer": 12, "half_answer": 6}}}
