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_CerUXRs):
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"

Question 1 (Question id: q_B6wx):
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.

Each key’s value must be an object holding an 'answer' field.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
If the question asks for the last character of a string, add an 'original_string' field containing the source string.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked – total number of questions originally shown.
Add 'num_questions_answered' showing how many questions you answered.
• questions_with_integer_answers: ids of questions with integer replies.

Now provide the result JSON using the described format.

{"ground_truth": {"q_CerUXRs": {"answer": "t", "original_string": "part"}, "q_B6wx": {"answer": "d", "original_string": "and"}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2, "questions_with_integer_answers": []}}}
