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_bFwp):
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: "water"

Question 1 (Question id: q_qapV1xG):
How many times does the letter "t" appear in the text: "sitting with"? Respond with an integer.



Return a JSON with each question id as a key.

The value for each key should be an object that contains the answer in the field 'answer'.
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.

Now provide the result JSON using the described format.

{"ground_truth": {"q_bFwp": {"answer": "r", "first_char": "r", "original_string": "water"}, "q_qapV1xG": {"answer": 3}}}
