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_FUnA):
Calculate ( 6 - -4 ) + -6.

Question 1 (Question id: q_nvhE3zxU):
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: "the"



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
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_FUnA": {"answer": 4, "additional_answer_info": {"half_answer": 2, "double_answer": 8}}, "q_nvhE3zxU": {"answer": "e"}}}
