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_J0y4V):
Find the value of t in the equation: 7*t + 17 = 80 Respond with an integer.

Question 1 (Question id: q_Q7O88):
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: "their"

Question 2 (Question id: q_1cVV7o):
Solve for q: 9*q + 18 = 27 Respond with an integer.

Question 3 (Question id: q_PIgix):
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: "teaches"



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
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.
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.
