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_hu7vn):
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: "as"

Question 1 (Question id: q_RWj4XiG):
Calculate 0 + 9 - 5.

Question 2 (Question id: q_v5okMq6):
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"



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'.
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).
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.
• questions_with_integer_answers: ids of questions with integer replies.

Now provide the result JSON using the described format.

{"ground_truth": {"q_hu7vn": {"answer": "s", "original_string": "as"}, "q_RWj4XiG": {"answer": 4, "additional_answer_info": {"half_answer": 2, "double_answer": 8}}, "q_v5okMq6": {"answer": "d", "original_string": "and"}, "global_metadata": {"num_questions_asked": 3, "questions_with_integer_answers": ["q_RWj4XiG"]}}}
