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_YH3lYj):
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: "things"

Question 1 (Question id: q_xZUkBv5Y):
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: "economy"

Question 2 (Question id: q_COQsy):
How many times does the letter "f" appear in the text: "of this license"? Respond with an integer.



Output JSON where all question ids are keys, omitting q_COQsy.

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.
If the response to a question is an integer that is even, add the field 'additional_answer_info' containing 'half_answer' (answer ÷ 2) and 'double_answer' (answer × 2).
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_xZUkBv5Y": {"answer": "y", "answer_type": "string", "first_char": "y", "original_string": "economy"}, "q_YH3lYj": {"answer": "s", "answer_type": "string", "first_char": "s", "original_string": "things"}}}
