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_0DESb):
Determine the value of q that satisfies: 70*q + 1 = 211 Respond with an integer.

Question 1 (Question id: q_SFSxk):
Find the value of t in the equation: 7*t + 17 = 80 Respond with an integer.

Question 2 (Question id: q_3VRs):
Determine the value of b that satisfies: 216*b = 2592 Respond with an integer.

Question 3 (Question id: q_zljPBKe4):
Calculate 6 * ( -6 * -3 ).



Return a JSON with each question id (except for q_zljPBKe4) as a key.

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