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_tuH0gAt):
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: "can"

Question 1 (Question id: q_402L):
Calculate ( 6 - 4 ).

Question 2 (Question id: q_UjLqrd):
Solve for q: -6*q - 12 = -108 Respond with an integer.



Return a JSON with each question id (except for q_402L) as a key.

For every question id, supply an object whose 'answer' field stores the solution. If a question involves animal-leg or letter counting, include 'task_type' set to 'leg_counting' or 'letter_counting'.
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.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_UjLqrd": {"answer": 16, "answer_type": "integer", "additional_answer_info": {"half_answer": 8, "double_answer": 32}}, "q_tuH0gAt": {"answer": "n", "answer_type": "string", "first_char": "n"}}}
