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: I have been using the term ofcourse ever since kindergarten. However, I recently stumbled upon a site that claims of course is how the term is correctly used and not ofcourse. I would like to seek the community's opinion about which is the correct usage of that term.
Answer: "Of course" is two words. I have never seen it as one except in typos and this question.
Example Output: yes

Example Input: Question: I keep writing dataset. Is that correct, or should I write data set?
Answer: As @mmyers notes, dataset does not appear in any dictionaries. However, there are 172 incidences in the Corpus of Contemporary American English, and all but a handful are in the "academic" section, representing formal academic writing. Its lack of appearance in dictionaries is probably because it is a fairly new coinage, the two examples from the Corpus of Historical American English are from 2001. Nothing from before then. Interestingly, the British National Corpus has 51 incidences, dating from the 1980s to the mid 1990s.
Example Output: yes

Example Input: Question: How to describe a person in a word who keeps mentioning about his own life story or about himself for every topic that is being conversed? Be it interesting or boring, he has the ability to pick out something that has happened to him or he himself creates a chance to talk about himself. Edit: The person is not selfish. He does care for others. I am just saying that the person relates everything to his life and talks about it, that too not even in a conceited way. This person is experienced enough to relate everything to things that has happened to him.
Answer: A 'megalomaniac' person which it means a person who is obsessed with his/her own power.
Example Output:
no
