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_tI87ML):
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_DZ4B):
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: "bigger"

Question 2 (Question id: q_jztQv):
Determine the value of m that satisfies: 10*m + 36 = 186 Respond with an integer.



Create a JSON object keyed by every question id except q_tI87ML.

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, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_DZ4B": {"answer": "r", "original_string": "bigger"}, "q_jztQv": {"answer": 15}, "global_metadata": {"num_questions_asked": 3, "questions_with_integer_answers": ["q_jztQv"]}}}
