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_s7ub):
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: "this"

Question 1 (Question id: q_RBtGqe):
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: "part"



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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 string answers, include 'first_char' with the answer’s initial letter.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
• num_questions_answered: count of questions present in your JSON.
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_s7ub": {"answer": "s", "answer_type": "string", "first_char": "s", "original_string": "this"}, "q_RBtGqe": {"answer": "t", "answer_type": "string", "first_char": "t", "original_string": "part"}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2, "questions_with_integer_answers": []}}}
