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_BfhqlbBY):
Calculate ( -2 - -5 ).

Question 1 (Question id: q_JNwa9kpe):
Solve for n: 35 - 18*n = 17 Respond with an integer.

Question 2 (Question id: q_7JAu7g):
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 4 ants, 3 sheeps, 1 praying mantis, 3 grasshoppers?
 Respond with an integer.

Question 3 (Question id: q_yqvs):
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: "and"

Question 4 (Question id: q_LdzK):
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: "and"



Output JSON where all question ids are keys, omitting q_JNwa9kpe.

For every question id, supply an object whose 'answer' field stores the solution.
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).
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.
