Detailed Instructions: 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.
See one example below:
Problem: 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.
Solution: yes
Explanation: The answer is well in context with the question and gives a proper explanation to resolve it. Hence, the output "yes" is correct.

Problem: Question: As an adverb, what is the difference between forward and forwards?
Answer: The OED says this The present distinction in usage between forward and forwards is that the latter expresses a definite direction viewed in contrast with other directions. In some contexts either form may be used without perceptible difference of meaning; the following are examples in which only one of them can now be used: 'The ratchet-wheel can move only forwards'; 'the right side of the paper has the maker's name reading forwards'; 'if you move at all it must be forwards'; 'my companion has gone forward'; 'to bring a matter forward'; 'from this time forward'. The usage of earlier periods, and of modern dialects, varies greatly from that of mod. standard English. In U.S. forward is now generally used, to the exclusion of forwards, which was stigmatized by Webster (1832) as 'a corruption'.
Solution:
yes
