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_odZQn):
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: "themselves"

Question 1 (Question id: q_AA7tKC):
Find the value of e in the equation: 27 - e = 12 Respond with an integer.



Output JSON where all question ids are keys, omitting q_AA7tKC.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
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: how many questions were asked in total.
Fill 'questions_with_integer_answers' with the ids of integer-answer questions (leave empty when none).

Attach a 'combined_results' object that contains:
  • integer_info: maps each id to its integer answer
  • sum_of_answers: the combined total

Now provide the result JSON using the described format.

{"ground_truth": {"q_odZQn": {"answer": "s", "original_string": "themselves"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": []}, "combined_results": {"integer_info": {}, "sum_of_answers": 0}}}
