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_iMfhz):
Calculate -2 + -5 * -4.

Question 1 (Question id: q_UinVjw0e):
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 ducks, 4 flatworms, 2 fireflys, 4 giraffes?
 Respond with an integer.

Question 2 (Question id: q_qHPZk5v):
Calculate -2 * -1 + -2.

Question 3 (Question id: q_P6vF):
How many times does the letter "o" appear in the text: "be done"? Respond with an integer.



Return a JSON with each question id (except for q_iMfhz) as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
