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_0lh7C):
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: "people"

Question 1 (Question id: q_GZNfI):
Calculate 2 + -9 + 8.

Question 2 (Question id: q_es4ua):
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 butterflys, 2 spiders, 3 tigers, 4 grasshoppers?
 Respond with an integer.

Question 3 (Question id: q_7WOp5uY):
Solve for e: 19*e + 6 = 158 Respond with an integer.



Output JSON where all question ids are keys, omitting q_es4ua.

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.
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.
