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_npBEo4):
Solve for h: 18 - 5*h = -67 Respond with an integer.

Question 1 (Question id: q_4SH0S):
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: "what"

Question 2 (Question id: q_Bxc74NW):
Calculate ( ( -4 * -2 ) ) - -2.



Return a JSON with each question id (except for q_npBEo4) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Now provide the result JSON using the described format.

{"ground_truth": {"q_Bxc74NW": {"answer": 10, "additional_answer_info": {"half_answer": 5, "double_answer": 20}}, "q_4SH0S": {"answer": "t"}}}
