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_zVLYjki):
Calculate ( 9 - -1 ).

Question 1 (Question id: q_GWro):
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: "the"



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

Each key’s value must be an object holding an 'answer' field.
For even integer answers, include 'half_answer' equal to answer ÷ 2.
For string answers, include 'first_char' with the answer’s initial letter.

Add a top-level 'global_metadata' field that records overall stats:
• 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).

In addition, add 'combined_results' with:
  • 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_GWro": {"answer": "e", "first_char": "e"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": []}, "combined_results": {"integer_info": {}, "sum_of_answers": 0}}}
