Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: yes
Reason: 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 instance: Question: Possible Duplicate: This question has been asked at/on SO? Which sentence is grammatically correct? The papers are freely available at the journal website. The papers are freely available on the journal website. Using Google's search results: available at the website returns 72,800,000 results. available on the website returns 106,000,000 results. So, I inferred that both variants are popular. Is this method (comparing the number of results by Googling) sound?
Answer: Speaking as a longtime computer geek, files are said to reside on a hard drive or on a certain machine. Since I know that a website is made of computer files, I think of a website as being on a machine and so any part of the website is also on that machine. A website's "address" is a "Uniform Resource Locator" or URL. These terms connote the idea of website as "place". In this case the file would be at the website location. So, if you think of a website as it is actually constructed (files stored on hard drives), you will probably say on. If you think in the location metaphor, you will probably say at. Personally I find myself saying "on" to other geeks and falling into "at" when speaking with normal people.
