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_0TZxSAe):
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: "changing"

Question 1 (Question id: q_v8kK5P):
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 beetle, 4 grasshoppers, 2 flatworms, 1 lobster, 2 cockroachs?
 Respond with an integer.

Question 2 (Question id: q_eMrP):
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: "what"



Return a JSON with each question id as a key.

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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_0TZxSAe": {"answer": "g"}, "q_v8kK5P": {"answer": 52, "additional_answer_info": {"half_answer": 26, "double_answer": 104}}, "q_eMrP": {"answer": "t"}}}
