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_ApAds):
Calculate 8 / 1 + 7.

Question 1 (Question id: q_bL0vBTri):
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: "a"

Question 2 (Question id: q_yQQBnA):
Calculate ( ( 2 + 2 ) ).

Question 3 (Question id: q_1OA5OL):
Calculate -4 * -2.

Question 4 (Question id: q_fFl6bV):
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 3 insects, 4 cows, 2 jellyfishs, 2 lobsters, 4 sea slugs?
 Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
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.
