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: Is there a word which has this definition: usage of vulgar or abusive words too often especially while chatting or talking to someone or while giving a speech. What do you call a person who uses abusive words too often without needing to. 
Answer: Perhaps not as technically accurate, but I've always liked uncouth: discourteous, rude, uncivil. See boorish. ... as listed under the Synonyms section of dictionary.com's entry An anonymous user suggested "couthless" as an alternative - but the online dictionary I use to double-check my thinking didn't list it as a "real" word. (Couth is a real word.) Your mileage may vary.

Ex Output:
no


Ex Input:
Question: I am looking for a word that describes a person described in the description of the title. An example of such a person would be a person who comfortably passes the (easier) qualifiers and gradually performs even better as opponents get tougher in the final stages of a tournament. The person does not necessarily relax when he knows he can easily win, but "naturally" performs better as the stakes get higher. 
Answer: The phrase that describes the act of matching skill/performance according to degree of hardness is "rise to the occasion." I am not aware of a single word that is synonymous with this concept.

Ex Output:

yes
