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_yOJOqh2Y):
Calculate -8 - -8.

Question 1 (Question id: q_hwpU9):
Solve for f: 9*f + 2 = 146 Respond with an integer.

Question 2 (Question id: q_dYunmD7):
Calculate ( -3 + 9 ) - 5.

Question 3 (Question id: q_UhiJTA):
Solve for f: 13 - 5*f = -22 Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
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, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.

Now provide the result JSON using the described format.
