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_gjDM):
Solve for q: -6*q - 12 = -108 Respond with an integer.

Question 1 (Question id: q_W2U4kFb):
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: "why"

Question 2 (Question id: q_6gIQr4C):
Solve for e: 19*e + 6 = 158 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_gjDM": {"answer": 16, "answer_type": "integer", "additional_answer_info": {"half_answer": 8, "double_answer": 32}}, "q_W2U4kFb": {"answer": "y", "answer_type": "string", "first_char": "y"}, "q_6gIQr4C": {"answer": 8, "answer_type": "integer", "additional_answer_info": {"half_answer": 4, "double_answer": 16}}}}
