Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.

Example input: Question: What's the difference between the following examples: Neither of my teachers are mathematicians. None of my teachers are mathematicians.
Answer: Neither - not either - implies that there is a choice of only two. So 'neither of my teachers' is only correct if there are exactly two teachers, 'none of my teachers' can be any number.
Example output: yes
Example explanation: The answer is well in context with the question and gives a proper explanation to resolve it. Hence, the output "yes" is correct.
Q: Question: There is a question titled "Does calling a road 'wavy' convey its shape clearly?" which looks like this is a duplicate, but in fact, it's not. In that question, there's talk of a road that slightly bends right and left, not up and down. So how do you describe a road that is up down and road? I am confused which word to use. There is one word to describe it. Can I say it is a zig-zag road?
Answer: "Undulate" is often used for roads that go up and down, while 'zig-zag' is used for roads that repeatedly bend to the left and right. The road undulates for three miles before descending into a valley. I enjoy an undulating road while driving, but not while cycling.
A:
yes
