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_XD9Lj):
Calculate ( 8 - 8 ).

Question 1 (Question id: q_jfGvd2):
Calculate ( ( ( -8 * 0 ) ) / 7 ).

Question 2 (Question id: q_VKUbYuAx):
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 lions, 3 birds, 1 firefly, 2 crabs?
 Respond with an integer.

Question 3 (Question id: q_1uu9p):
How many times does the letter "n" appear in the text: "Jules Verne"? Respond with an integer.

Question 4 (Question id: q_ejg1AId):
Calculate 7 + -3.



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

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer 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).
If the response to a question is a string, add a 'first_char' field containing its first character.
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.
