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_V6u6fj2T):
Calculate 7 - -8 / 8.

Question 1 (Question id: q_ji7zGY):
How many times does the letter "u" appear in the text: "expose yourself to"? Respond with an integer.



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

Each key’s value must be an object holding an 'answer' field.
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.
For last-character tasks, provide 'original_string' alongside the answer.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
'num_questions_asked' should equal the total questions that appeared.
'num_questions_answered' must hold the number of answered questions.
• 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_V6u6fj2T": {"answer": 8, "additional_answer_info": {"half_answer": 4, "double_answer": 16}}, "q_ji7zGY": {"answer": 1}, "global_metadata": {"num_questions_asked": 2, "num_questions_answered": 2, "questions_with_integer_answers": ["q_V6u6fj2T", "q_ji7zGY"]}}}
