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_OGmRG7bE):
Calculate -2 * -6 - -7.

Question 1 (Question id: q_bUqAC):
Find the value of b in the equation: 4*b + 7 = 27 Respond with an integer.

Question 2 (Question id: q_fGGOQoD8):
Determine the value of l that satisfies: 19*l + 31 = 50 Respond with an integer.



Return a JSON with each question id as a key.

Each key’s value must be an object holding an 'answer' field.
Include an 'answer_type' field (value 'string' or 'integer') for every answer 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 question asks for the last character of a string, add an 'original_string' field containing the source string.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.
• num_questions_answered: count of questions present in your JSON.

In addition, add 'combined_results' with:
  • integer_info: per-id integer answers
  • sum_of_answers: their total

Now provide the result JSON using the described format.
