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_Fu8z):
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: "for"

Question 1 (Question id: q_qXJ17asn):
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 cricket, 4 cockroachs, 3 butterflys, 1 sheep, 3 horses?
 Respond with an integer.

Question 2 (Question id: q_ehZnWJ1T):
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 crickets, 2 giraffes, 1 flatworm, 4 praying mantiss?
 Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

For every question id, supply an object whose 'answer' field stores the solution.
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.
