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_0YpAov):
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: "opponents"

Question 1 (Question id: q_KrqnW):
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 cat, 3 shrimps, 2 dogs, 2 ants?
 Respond with an integer.



Output JSON where all question ids are keys, omitting q_KrqnW.

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_0YpAov": {"answer": "s", "answer_type": "string", "first_char": "s"}}}
