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_3IR1):
Calculate ( -2 - -9 ).

Question 1 (Question id: q_D7Eb3):
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 grasshoppers, 3 sea slugs, 1 dog?
 Respond with an integer.

Question 2 (Question id: q_U2qbN6H):
Calculate -5 * -9 - 2.

Question 3 (Question id: q_nZ0cE):
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: "of"

Question 4 (Question id: q_aVZpM):
Calculate ( 8 - -1 ).

Question 5 (Question id: q_4RsO):
Calculate 8 + -6.



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

Each key’s value must be an object holding an 'answer' field.
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.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
