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 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: There was the following passage in New York Times' (October 6) article commenting on GOP Presidential candidate, Carly Fiorina under the headline, 'If she's a feminist, then I'm a T. Rex': "Her record at Hewlett-Packard firing skilled Americans by the thousands and outsourcing their jobs to China and India, while almost running her company into the ground with an ill-advised merger is hardly a sterling record for any sort of candidate, assuming we actually want a president of all the people rather than a modern Ebenezer Scrooge, - - This is a woman who would deny other women control over their own bodies, as well. "If she's a feminist then I'm a T. rex." According to Jurassic wiki, Tyrannosaurus rex, the most famous of all dinosaurs species and commonly known as T. rex, was the largest of the Tyrannosaur family and by extension one of the largest theropods, reaching 12 to 13 meters in length. But what does 'If she's a feminist, then I'm a T. Rex' mean? Does the writer sarcastically admit herself being anachronistic? Why should it be a T.Rex, not other monsterous or supernatural creatures, say, Moby-Dick and Godzilla? Is this a cute turn of phrase? Could you translate "I'm a T.rex" into plain English? 
Answer: All that that is saying is that she is no feminist whatsoever, being just as much of a feminist as the columnist is a giant extinct dinosaur. That is, not at all.
Example Output: yes

Example Input: Question: Possible Duplicate: What is the difference between an expression and a phrase? Difference between "phrase" and "idiom" What is the difference between a phrase, an idiom and an expression? I am looking for the context where one is more appropriate than the rest. I've been using idiom and phrase more or less interchangeably. 
Answer: This question asks nearly the same thing. This is the difference between an idiom and a phrase: A phrase is "a small group of words standing together as a conceptual unit", while an idiom is "a group of words established by usage as having a meaning not deducible from those of the individual words". So, the difference is that an idiom as an established meaning not directly linked to the individual words. Any idiom is a phrase. As an example, "raining cats and dogs" is both an idiom and a phrase. "A herd of cats" is a phrase but not an idiom. Expression has about the same meaning as phrase, except it is usually used of a phrase which is in common use. So an idiom is a certain sort of expression, which in turn is a subset of phrase: idiom > expression > phrase.
Example Output:
yes
