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_l7WNWK):
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: "we"

Question 1 (Question id: q_zxaW):
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 insect, 3 praying mantiss, 2 humans?
 Respond with an integer.

Question 2 (Question id: q_O4bn):
Solve for w: 26 - 3*w = 23 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

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_l7WNWK": {"answer": "e"}, "q_zxaW": {"answer": 28, "additional_answer_info": {"half_answer": 14, "double_answer": 56}}, "q_O4bn": {"answer": 1}}}
