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_LFPFcQYd):
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: "and"

Question 1 (Question id: q_aAVnJRs):
Calculate 9 / 9 + 4.



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

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).

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Now provide the result JSON using the described format.

{"ground_truth": {"q_LFPFcQYd": {"answer": "d"}, "q_aAVnJRs": {"answer": 5}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_aAVnJRs"]}}}
