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_ZFo9Hec):
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: "powerful"

Question 1 (Question id: q_rZShwP8):
Determine the value of v that satisfies: 9*v + 9 = 108 Respond with an integer.

Question 2 (Question id: q_cSu7):
How many times does the letter "w" appear in the text: "would do anything"? 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. Additionally, if the task is about counting legs of animals or counting letters in a string, add the task_type field with value 'leg_counting' or 'letter_counting', respectively.
If the response to a question is an integer that is even, also add the field 'half_answer' to the object which contains the answer integer divided by two.
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_ZFo9Hec": {"answer": "l", "first_char": "l", "original_string": "powerful"}, "q_rZShwP8": {"answer": 11}, "q_cSu7": {"answer": 1, "task_type": "letter_counting"}}}
