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_TQcvS):
Determine the value of n that satisfies: 8 - 18*n = -172 Respond with an integer.

Question 1 (Question id: q_wEqNWo):
Solve for a: 12*a - 1 = 95 Respond with an integer.

Question 2 (Question id: q_C2Uq7u):
Determine the value of e that satisfies: e + 19 = 39 Respond with an integer.



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

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.
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.
