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_Clji):
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: "when"

Question 1 (Question id: q_Wda79):
How many times does the letter "n" appear in the text: "department and tell"? Respond with an integer.



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

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

Now provide the result JSON using the described format.

{"ground_truth": {"q_Clji": {"answer": "n", "first_char": "n", "original_string": "when"}, "q_Wda79": {"answer": 2, "task_type": "letter_counting", "additional_answer_info": {"half_answer": 1, "double_answer": 4}}}}
