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_zxp0wWGy):
Find the value of u in the equation: 90*u - 6 = 1074 Respond with an integer.

Question 1 (Question id: q_Ez2l):
Find the value of g in the equation: 90*g = 720 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

Each key’s value must be an object holding an 'answer' field.
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_zxp0wWGy": {"answer": 12, "half_answer": 6}, "q_Ez2l": {"answer": 8, "half_answer": 4}}}
