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_1UJTdz):
Calculate 1 + 1.

Question 1 (Question id: q_WqBEXP0U):
Calculate 6 / 2 + 2.

Question 2 (Question id: q_272DNM):
Calculate ( ( 5 + 2 ) ).

Question 3 (Question id: q_yfQv):
Calculate ( -1 - -4 ).

Question 4 (Question id: q_QoNq9f):
Determine the value of f that satisfies: 10*f - 15 = 95 Respond with an integer.

Question 5 (Question id: q_Fub1EM):
Calculate -2 * -1 + -2.



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

The value for each key should be an object that contains the answer in the field 'answer'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Now provide the result JSON using the described format.
