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_lbdFW):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "is"

Question 1 (Question id: q_eHFX):
Calculate ( ( 3 - -7 + -8 ) ).

Question 2 (Question id: q_97sPuM):
Solve for i: 36*i + 116 = 332 Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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_lbdFW": {"answer": "s", "answer_type": "string", "original_string": "is"}, "q_eHFX": {"answer": 2, "answer_type": "integer", "additional_answer_info": {"half_answer": 1, "double_answer": 4}}, "q_97sPuM": {"answer": 6, "answer_type": "integer", "additional_answer_info": {"half_answer": 3, "double_answer": 12}}}}
