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_rPyT):
Solve for o: -20*o - 23 = -83 Respond with an integer.

Question 1 (Question id: q_z6KQFF):
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"



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.
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 – total number of questions originally shown.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.

{"ground_truth": {"q_rPyT": {"answer": 3}, "q_z6KQFF": {"answer": "e", "first_char": "e"}, "global_metadata": {"num_questions_asked": 2, "questions_with_integer_answers": ["q_rPyT"]}}}
