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_iJfdm):
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: "are"

Question 1 (Question id: q_vrWK7JVW):
How many times does the letter "s" appear in the text: "eBooks may"? Respond with an integer.

Question 2 (Question id: q_ntdE1):
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: "rich"

Question 3 (Question id: q_QlAmH):
How many times does the letter "o" appear in the text: "for the whole"? Respond with an integer.

Question 4 (Question id: q_7rcEA0):
How many times does the letter "t" appear in the text: "a waterfall a"? Respond with an integer.



Your output must be a JSON mapping every question id to its answer info.

The value for each key should be an object that contains the answer in the field 'answer'.
Include an 'answer_type' field (value 'string' or 'integer') for every answer object.
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.
'questions_with_integer_answers' should enumerate every id whose answer is an integer.

Now provide the result JSON using the described format.
