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_TWyLtb):
Calculate ( 8 / 1 ) * 3.

Question 1 (Question id: q_Hh1DzdFQ):
Solve for q: 260*q - 480 = 560 Respond with an integer.

Question 2 (Question id: q_miCLWS):
How many times does the letter "s" appear in the text: "whole cities"? Respond with an integer.

Question 3 (Question id: q_c3hhX):
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: "survive"



Return a JSON with each question id as a key.

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.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Now provide the result JSON using the described format.
