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_ye7Sd):
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: "to"

Question 1 (Question id: q_7YeOeG):
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: "just"



Output JSON where all question ids are keys, omitting q_7YeOeG.

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 response to a question is a string, add a 'first_char' field containing its first character.
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' should equal the total questions that appeared.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_ye7Sd": {"answer": "o", "first_char": "o", "original_string": "to"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": []}}}
