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.

Ex Input:
Question: I've heard people say "be king" (as in "I can't wait to be king") in movies and TV. Why don't they say "be a king"? Which is correct? 
Answer: Since "a king" uses an indefinite article, it suggests that he may become any one of a number of kings. In most cases where a person may become king, there is only one king in the political structure he inhabits. For instance, if he is in the line of succession for the English throne, he probably cannot become king of France or Denmark without marrying into that royal family. The equivalent phrase to "I can't wait to be king" would use a definite article - it could be rephrased as "I can't wait to be the king", since there is only one kingship he is eligible to accede to.

Ex Output:
yes


Ex Input:
Question: What's the difference between these two phrases? 
Answer: The difference is pretty subtle, but the "did you..." version implies more of an event, i.e. something that needs to be seen just once, perhaps because it's temporary. So, Have you seen [insert movie title]? but Did you see last night's [insert TV show name] episode? Edit: note that there's nothing wrong with "Have you seen last night's episode?", or with "Did you see the movie?", but there is a (slight) difference in meaning.

Ex Output:
no


Ex Input:
Question: Is it ok to talk about "personal PCs", in the sense of distinguishing it from a work PC? Or would it be regarded as a case of RAS Syndrome? 
Answer: Though the word personal is repeated in the expansion "personal personal computer", the two repetitions use different meanings of the same word. The first personal means "owned or used by a specific single person" (definition 1 here), while the second indicates "designed to be used by a single person" (definition 2 here, again). Both instances are required to convey the full idea and thus are not redundant. Consider the following examples spelled out in full: Personal PC: personal personal computer, (the usual case of a personal computer owned by a person) personal mainframe computer (I have a Cray in my bedroom), Public PC: public personal computer (a PC that is installed in a kiosk usable by anybody).

Ex Output:

yes
