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_W97xB5v):
Calculate ( ( ( 6 + 7 ) ) - -4 ).

Question 1 (Question id: q_Jjfw9):
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: "biology"

Question 2 (Question id: q_vVsTTe):
Your task is to count how many legs there are in total when given a list of animals.

Now, how many legs are there in total if you have 1 ant, 1 giraffe, 1 insect?
 Respond with an integer.

Question 3 (Question id: q_X7OKbeB):
Calculate -5 * -3.



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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_W97xB5v": {"answer": 17}, "q_Jjfw9": {"answer": "y", "first_char": "y"}, "q_vVsTTe": {"answer": 16, "additional_answer_info": {"half_answer": 8, "double_answer": 32}}, "q_X7OKbeB": {"answer": 15}}}
