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_VB1gYrF):
Calculate ( 4 / 4 ).

Question 1 (Question id: q_HtFu):
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: "membrane"



Return a JSON with each question id as a key.

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.

Add a top-level 'global_metadata' field that records overall stats:
Include 'num_questions_asked' to record the total number of questions presented.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Attach a 'combined_results' object that contains:
  • integer_info (id → integer answer)
  • sum_of_answers (sum of those integers)

Now provide the result JSON using the described format.

{"ground_truth": {"q_VB1gYrF": {"answer": 1}, "q_HtFu": {"answer": "e"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_VB1gYrF"]}, "combined_results": {"integer_info": {"q_VB1gYrF": 1}, "sum_of_answers": 1}}}
