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_dWAOvq1j):
Calculate -1 * -8.

Question 1 (Question id: q_p5YDgUe):
Calculate 9 / 9 + 4.

Question 2 (Question id: q_103Ii3Ri):
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: "think"



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.
If the response to a question is a string, add a 'first_char' field containing its first character.
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: how many questions were asked in total.
• 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.
