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_JJbPVcE):
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_GruC):
How many times does the letter "i" appear in the text: "that from this"? Respond with an integer.

Question 2 (Question id: q_4QCX4d):
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 wasps, 1 cockroach, 2 praying mantiss?
 Respond with an integer.



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

The value for each key should be an object that contains the answer in the field 'answer'.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For string answers, include 'first_char' with the answer’s initial letter.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Now provide the result JSON using the described format.

{"ground_truth": {"q_4QCX4d": {"answer": 30, "additional_answer_info": {"half_answer": 15, "double_answer": 60}}, "q_JJbPVcE": {"answer": "d", "first_char": "d", "original_string": "and"}}}
