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_Nkf7JZ):
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: "and"

Question 1 (Question id: q_uhUk8d):
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 3 cockroachs, 4 starfishs, 2 wasps, 3 crickets, 2 giraffes?
 Respond with an integer.

Question 2 (Question id: q_Sp9e):
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: "expectations"



Create a JSON object keyed by every question id except q_Nkf7JZ.

The value for each key should be an object that contains the answer in the field 'answer'.
Also add the answer type as 'string' or 'integer' to the field 'answer_type' for each object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.

{"ground_truth": {"q_Sp9e": {"answer": "s", "answer_type": "string", "first_char": "s"}, "q_uhUk8d": {"answer": 76, "answer_type": "integer", "additional_answer_info": {"half_answer": 38, "double_answer": 152}}}}
