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_j87p1HX4):
Calculate 1 - 0.

Question 1 (Question id: q_WhZLIa):
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: "patience"

Question 2 (Question id: q_qHE0FZ):
How many times does the letter "s" appear in the text: "sun and to"? Respond with an integer.

Question 3 (Question id: q_iYvKs):
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 2 lobsters, 4 spiders, 2 leechs, 2 tigers?
 Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_j87p1HX4": {"answer": 1}, "q_WhZLIa": {"answer": "e", "original_string": "patience"}, "q_qHE0FZ": {"answer": 1}, "q_iYvKs": {"answer": 60, "additional_answer_info": {"half_answer": 30, "double_answer": 120}}}}
