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_se82n):
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_U1v6yne):
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: "a"



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.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
'num_questions_asked' should equal the total questions that appeared.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Create a 'combined_results' section featuring:
  • integer_info – object mapping ids to their integer answers
  • sum_of_answers – sum of those integers

Now provide the result JSON using the described format.

{"ground_truth": {"q_se82n": {"answer": "o"}, "q_U1v6yne": {"answer": "a"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": []}, "combined_results": {"integer_info": {}, "sum_of_answers": 0}}}
