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_xmBZl):
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 4 fireflys, 2 grasshoppers, 1 praying mantis?
 Respond with an integer.

Question 1 (Question id: q_iQPch):
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: "water"

Question 2 (Question id: q_Jc2M):
Solve for o: 17*o - 2 = 15 Respond with an integer.



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_xmBZl": {"answer": 42, "additional_answer_info": {"half_answer": 21, "double_answer": 84}}, "q_iQPch": {"answer": "r"}, "q_Jc2M": {"answer": 1}}}
