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_EMV95):
Find the value of b in the equation: 4*b + 7 = 27 Respond with an integer.

Question 1 (Question id: q_bABYcB7):
Calculate -3 - -6.



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'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For last-character tasks, provide 'original_string' alongside the answer.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked – total number of questions originally shown.

Also include 'combined_results' consisting of:
  • integer_info holds all integer answers by id
  • sum_of_answers is their sum

Now provide the result JSON using the described format.

{"ground_truth": {"q_EMV95": {"answer": 5}, "q_bABYcB7": {"answer": 3}, "global_metadata": {"num_questions_asked": 2}, "combined_results": {"integer_info": {"q_EMV95": 5, "q_bABYcB7": 3}, "sum_of_answers": 8}}}
