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_QxpH5ISK):
Find the value of w in the equation: 16*w - 15 = 81 Respond with an integer.

Question 1 (Question id: q_lzLzj):
Determine the value of g that satisfies: 8*g - 9 = 103 Respond with an integer.



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

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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.

Now provide the result JSON using the described format.

{"ground_truth": {"q_QxpH5ISK": {"answer": 6, "additional_answer_info": {"half_answer": 3, "double_answer": 12}}, "q_lzLzj": {"answer": 14, "additional_answer_info": {"half_answer": 7, "double_answer": 28}}, "global_metadata": {"num_questions_asked": 2}}}
