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_WKZGET):
Calculate 8 + -6.

Question 1 (Question id: q_bXgZjH):
Calculate 5 + ( -8 * -1 ).

Question 2 (Question id: q_pIgdXbr):
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: "or"



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

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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
• num_questions_asked: how many questions were asked in total.
'num_questions_answered' must hold the number of answered questions.

In addition, add 'combined_results' with:
  • integer_info holds all integer answers by id
  • sum_of_answers is their sum

Now provide the result JSON using the described format.

{"ground_truth": {"q_WKZGET": {"answer": 2, "half_answer": 1}, "q_pIgdXbr": {"answer": "r", "first_char": "r"}, "global_metadata": {"num_questions_asked": 3, "num_questions_answered": 2}, "combined_results": {"integer_info": {"q_WKZGET": 2}, "sum_of_answers": 2}}}
