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_oNf5BW):
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: "to"

Question 1 (Question id: q_ElxZuYW):
Determine the value of x that satisfies: -9*x - 20 = -182 Respond with an integer.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.
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:
'num_questions_asked' should equal the total questions that appeared.
• questions_with_integer_answers – list of question ids whose answers are integers (empty list if none).

Now provide the result JSON using the described format.

{"ground_truth": {"q_oNf5BW": {"answer": "o", "first_char": "o"}, "q_ElxZuYW": {"answer": 18, "additional_answer_info": {"half_answer": 9, "double_answer": 36}}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_ElxZuYW"]}}}
