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_LUscIVks):
Calculate ( 9 + 0 + -3 ).

Question 1 (Question id: q_jcpnm):
Calculate -4 + 8 - -5.

Question 2 (Question id: q_WTyubri):
Calculate -5 + 2 + 4.

Question 3 (Question id: q_6dtYa8u):
Find the value of f in the equation: -5*f - 30 = -70 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.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
If the response to a question is a string, add a 'first_char' field containing its first character.
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.
