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_3dy5):
How many times does the letter "f" appear in the text: "having left"? Respond with an integer.

Question 1 (Question id: q_7Ae1y):
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: "luck"



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.
If the response to a question is a string, add a 'first_char' field containing its first character.

Now provide the result JSON using the described format.

{"ground_truth": {"q_3dy5": {"answer": 1}, "q_7Ae1y": {"answer": "k", "first_char": "k"}}}
