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.

Question: Does "egoistic" and "egotistic" mean the same thing? 
Answer: No. While similar, they have some important differences. Consider this note on usage from the Oxford Dictionaries: The words egoism and egotism are frequently confused, as though interchangeable, but there are distinctions worth noting. Both words derive from Latin ego ('I'), the first-person singular pronoun. Egotism, the more commonly used term , denotes an excessive sense of self-importance, too-frequent use of the word 'I,' and general arrogance and boastfulness. Egoism, a more subtle term , is perhaps best left to ethicists, for whom it denotes a view or theory of moral behavior in which self-interest is the root of moral conduct. An egoist, then , might devote considerable attention to introspection, but could be modest about it, whereas an egotist would have an exaggerated sense of the importance of his or her self-analysis, and would have to tell everyone.

Ex Output:
yes


Ex Input:
Question: Which is correct? The thief carried the knife carefully so as not to cut himself. The thief carried the knife carefully not to cut himself. 
Answer: The first one. The second one sounds quite awkward, and in fact one way I can think of to improve it would be to add a comma: "The thief carried the knife carefully, not to cut himself". The slight pause is meant to suggest the missing "so as"!.

Ex Output:
yes

Question: There are many English words with silent letters, words like gnome or island that are spelt with consonants that aren't pronounced, but are there any words that work the other way round, with a pronunciation that includes extra sounds or syllables that are not in the spelling? I can't think of any real examples, hence this question, but a made-up example would be if gnome were spelt nome but pronounced with a g at the start. Or if people started pronouncing offer as "ofter" as a sort of weird parallel to after. Note: I don't mean words like rough, where the f sound is spelt gh, because in those cases the spelling does still include letters (however seemingly illogical) for each of the sounds. 
Answer: The name "Stephen" is pronounced as "Steven", that is, "ph" is pronounced "v", which is unexpected. Some notes: "ph" is normally pronounced "f", and both "v" and "f" are labiodental fricatives, so this strange pronunciation doesn't come entirely out of the blue. The name can also be spelt "Steven" (e.g. Steven Tyler), thus matching the pronunciation. Admittedly, this is not exactly what you are asking for (it's like "colonel", where "lo" is pronounced as an "r"), but since you consider colonel "in an adjacent neighbourhood", you might be interested in "Stephen" as well.

no
