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_Y9tn4):
Solve for e: 5*e - 17 = 83 Respond with an integer.

Question 1 (Question id: q_hlYOxI):
Calculate ( ( 2 + 2 ) ).

Question 2 (Question id: q_LSh3PSmf):
Determine the value of u that satisfies: -19*u - 2 = -59 Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

For every question id, supply an object whose 'answer' field stores the solution.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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.
