Correct Response = "With yield" Incorrect Response = "Without yield" While "Incorrect
Response" appears more detailed and elaborate, it does not properly answer the given prompt.
The prompt asks for writing a generator function to yield the Fibonacci numbers, but "In-correct
Response" provides a normal function that returns a list of Fibonacci numbers. On the other
hand, "Correct Response" exactly follows the prompt, providing a generator function that can
yield Fibonacci numbers indefinitely. This is why "Correct Response" is the better response in
terms of Relevance to the prompt, even though it might seem less flashy than "In-correct
Response". Also, the error in "Incorrect Response" is somewhat subtle because it will still
produce Fibonacci numbers; the key is recognizing that it's not the right type of function for the
given task. Hence, the issue being a medium one to identify.
