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 need a single-word to describe something good that (unexpectedly) resulted from something bad. This good thing could not have occurred without the bad event happening first, as a precursor. Example sentence: "I got in a horrible car accident and broke my leg, but falling in love with my nurse at the hospital was the ____," (something like that). 
Answer: The word irony has undergone a bit of a semantic shift and is often used for a perceived contradiction, among others a contradiction between one's expectations and an actual fact or event. Merriam-Webster gives as one of its meanings incongruity between the actual result of a sequence of events and the normal or expected result and continues with examples in which the outcome is worse than expected; but it can be used for better outcomes as well, like in your case: "Falling in love with the nurse was the irony of my accident." Or "ironically, getting fired was the best thing that had happened to me in a long time".
Example Output: no

Example Input: Question: This came up recently on programmers.SE, when someone (a Russian, presumably non-native English speaker) asked why we used the term "sister sites", instead of "brother sites". Of course, I'm a native English speaker, and I have no idea either, hence this question. The full question, for context, was "Several of our sister sites have taken to featuring Questions [...]". It does seem odd, considering that English (usually) uses masculine terms as the default. 
Answer: It is because only female carries the direct increase/multiplication through reproduction; that's why we also say mother tongue.
Example Output:
no
