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_fCZO):
Your job is to return the last character of a string as a string. For example, the last char of "hello" is "o". Return the last character of the following string: "people"

Question 1 (Question id: q_T1GdH):
Solve for i: 6*i + 30 = 72 Respond with an integer.

Question 2 (Question id: q_fxHQ):
Find the value of v in the equation: 17*v + 4 = 55 Respond with an integer.

Question 3 (Question id: q_UQ0c1):
Solve for b: 17*b + 24 = 143 Respond with an integer.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
For string answers, include 'first_char' with the answer’s initial letter.
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: how many questions were asked in total.
Record the answered-question count in the field 'num_questions_answered'.

Now provide the result JSON using the described format.

{"ground_truth": {"q_fCZO": {"answer": "e", "first_char": "e", "original_string": "people"}, "q_T1GdH": {"answer": 7}, "q_fxHQ": {"answer": 3}, "q_UQ0c1": {"answer": 7}, "global_metadata": {"num_questions_asked": 4, "num_questions_answered": 4}}}
