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_H2gVF):
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: "that"

Question 1 (Question id: q_aVtEJHT):
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: "is"

Question 2 (Question id: q_2Irm):
Calculate 0 * 6.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
For last-character tasks, provide 'original_string' alongside the answer.

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_H2gVF": {"answer": "t", "original_string": "that"}, "q_aVtEJHT": {"answer": "s", "original_string": "is"}, "q_2Irm": {"answer": 0, "additional_answer_info": {"half_answer": 0, "double_answer": 0}}, "global_metadata": {"num_questions_asked": 3}}}
