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_mxAsJZg):
Calculate 5 * 7.

Question 1 (Question id: q_wFdj1c):
Calculate 2 + 8 + 3.

Question 2 (Question id: q_u3Abtktn):
Find the value of e in the equation: 27 - e = 12 Respond with an integer.

Question 3 (Question id: q_Mga7vfA):
Calculate -3 - 8 * -5.



Return a JSON with each question id (except for q_Mga7vfA) as a key.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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_wFdj1c": {"answer": 13}, "q_mxAsJZg": {"answer": 35}, "q_u3Abtktn": {"answer": 15}}}
