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_8U2Ic4):
Calculate 7 / 1 + 0.

Question 1 (Question id: q_B6px):
Calculate ( 9 + 2 ) - -8.

Question 2 (Question id: q_0nTJCCe):
Calculate ( 6 - 7 ) - -3.

Question 3 (Question id: q_PaPRw2):
Solve for q: 33 - 15*q = -207 Respond with an integer.



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'.
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, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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.
