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_V4Ez):
Determine the value of b that satisfies: 11*b + 14 = 36 Respond with an integer.

Question 1 (Question id: q_11x2A):
Solve for i: 12*i - 11 = 73 Respond with an integer.

Question 2 (Question id: q_BdLM):
Determine the value of s that satisfies: 4 - 4*s = -76 Respond with an integer.



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

For every question id, supply an object whose 'answer' field stores the solution.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_V4Ez": {"answer": 2, "half_answer": 1}, "q_11x2A": {"answer": 7}, "q_BdLM": {"answer": 20, "half_answer": 10}}}
