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_ZiGL9):
Calculate 1 - -1.

Question 1 (Question id: q_kdaEakw):
Calculate 3 + 1 / 1.

Question 2 (Question id: q_qZT0u):
Solve for z: -11*z - 6 = -116 Respond with an integer.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
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.
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_ZiGL9": {"answer": 2, "half_answer": 1}, "q_kdaEakw": {"answer": 4, "half_answer": 2}, "q_qZT0u": {"answer": 10, "half_answer": 5}}}
