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.
One example: 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 is here: 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.

Now, solve this: Question: Possible Duplicate: When is "L" doubled? If I am using the word model in the context of financial models and the UK, then which of these words should I use? Also, are there any key difference in the meanings of the two? 
Answer: There is no difference in meaning. The single-L spelling is more common in the United States; the double-L spelling is more common in the United Kingdom, Australia, South Africa and New Zealand. I don't know which is more common in other countries.
Solution:
yes
