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_yBWa9):
Calculate 2 * 4 - 4.

Question 1 (Question id: q_yAdWZO):
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: "can"

Question 2 (Question id: q_rwWO):
How many times does the letter "t" appear in the text: "Toward the"? Respond with an integer.



Return a JSON with each question id as a key.

For every question id, supply an object whose 'answer' field stores the solution.
For even integers, nest 'half_answer' and 'double_answer' inside an additional 'additional_answer_info' field in the answer object.

Beyond the question-id fields, add a 'global_metadata' object with summary information:
Include 'num_questions_asked' to record the total number of questions presented.
• num_questions_answered – number you actually answered.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.
