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_aBliYxMv):
Calculate 0 + 9 - 4.

Question 1 (Question id: q_CZyrkQ):
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: "others"

Question 2 (Question id: q_yMNBJXd):
Calculate 5 + 0 + 8.

Question 3 (Question id: q_VCdNTZnb):
Calculate -5 * 0.

Question 4 (Question id: q_XKbupg2g):
How many times does the letter "y" appear in the text: "You must not"? Respond with an integer.

Question 5 (Question id: q_mpnZ):
Solve for n: 35 - 18*n = 17 Respond with an integer.

Question 6 (Question id: q_TSstp):
Solve for f: -4*f - 15 = -31 Respond with an integer.

Question 7 (Question id: q_qx6F):
Find the value of p in the equation: 5*p + 15 = 65 Respond with an integer.



Return a JSON with each question id (except for q_yMNBJXd, q_TSstp) as a key.

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.
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.
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.
