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_LiwS):
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: "and"

Question 1 (Question id: q_6UoY):
Find the value of d in the equation: 12*d - 1 = 191 Respond with an integer.



Produce a JSON object whose top-level keys are the question ids.

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 string answers, include 'first_char' with the answer’s initial letter.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Set 'num_questions_asked' to the count of questions originally displayed.
Add 'num_questions_answered' showing how many questions you answered.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Also include 'combined_results' consisting of:
  • integer_info (id → integer answer)
  • sum_of_answers (sum of those integers)

Now provide the result JSON using the described format.

{"ground_truth": {"q_LiwS": {"answer": "d", "first_char": "d"}, "q_6UoY": {"answer": 16, "half_answer": 8}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2, "questions_with_integer_answers": ["q_6UoY"]}, "combined_results": {"integer_info": {"q_6UoY": 16}, "sum_of_answers": 16}}}
