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_wvZMIHH):
Solve for t: 15*t + 24 = 294 Respond with an integer.

Question 1 (Question id: q_v89inbvU):
Find the value of y in the equation: 126 - 252*y = -4914 Respond with an integer.

Question 2 (Question id: q_qOuCd2I):
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: "humans"



Return a JSON with each question id 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 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.
