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_o3ZkR):
Calculate -2 / 2 + 4.

Question 1 (Question id: q_SL9pOJ):
How many times does the letter "s" appear in the text: "is not"? Respond with an integer.

Question 2 (Question id: q_XrEX):
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: "sports"

Question 3 (Question id: q_7fBnn):
Calculate 9 + 4 - 4.

Question 4 (Question id: q_64LM):
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"



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 question asks for the last character of a string, add an 'original_string' field containing the source string.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Set 'num_questions_asked' to the count of questions originally displayed.
Provide 'questions_with_integer_answers', listing ids with integer answers (or [] if no integers).

Now provide the result JSON using the described format.
