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_l8aBX):
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: "major"

Question 1 (Question id: q_24ndbNE):
Calculate ( 3 - 3 ).



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.

Add a top-level 'global_metadata' field that records overall stats:
• num_questions_asked: how many questions were asked in total.

Now provide the result JSON using the described format.

{"ground_truth": {"q_l8aBX": {"answer": "r"}, "q_24ndbNE": {"answer": 0, "additional_answer_info": {"half_answer": 0, "double_answer": 0}}, "global_metadata": {"num_questions_asked": 2}}}
