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_g5mqJ):
Calculate 2 - -4.

Question 1 (Question id: q_bAMc2Aa):
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: "microscopes"

Question 2 (Question id: q_hxxnD4t):
Find the value of m in the equation: -8*m - 1 = -97 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.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
'num_questions_asked' should equal the total questions that appeared.

Now provide the result JSON using the described format.

{"ground_truth": {"q_g5mqJ": {"answer": 6, "additional_answer_info": {"half_answer": 3, "double_answer": 12}}, "q_bAMc2Aa": {"answer": "s", "first_char": "s"}, "q_hxxnD4t": {"answer": 12, "additional_answer_info": {"half_answer": 6, "double_answer": 24}}, "global_metadata": {"num_questions_asked": 3}}}
