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: Is there a specific reason for this? After all, it is "boys and girls", rather than "girls and boys". If the boy (male) comes first here, why doesn't it come first in "ladies and gentlemen"?
Answer: It probably has to do with the phonetic and metrical properties of "ladies and gentlemen" versus "gentlemen and ladies." Say them both out loud and see which one sounds better to you, intuitively. The metrical pattern of "ladies and gentlemen" consists of (arguably) two dactyls. A dactyl is a group of three syllables where the first is stressed and the second two are unstressed. When these occur in succession, they are pleasant to the ear. ladies and gentlemen DUM da da / DUM da da The metrical pattern of "gentlemen and ladies" falls into a much less regular pattern. It is less pleasant to the ear. It is something like a stressed syllable followed by three unstressed syllables followed by a stressed syllable followed by an unstressed syllable. gentlemen and ladies DUM da da da DUM da Our language tends to organize itself according to regular and pleasant stress patterns. My guess is that is why we feel more drawn to "ladies and gentlemen" than "gentlemen and ladies" and why the former has conventionalized.

Question: As a programmer I use the word Authentication and the word Authorisation in my code. I'd like to find nice abbreviations or alternative words for each of them that are not ambiguous and has reasonably large 'psychological distance' between. i.e. they don't look too similar i.e 'Auth' is not OK because it is ambiguous. At the moment I have just removed some letters Authtictn Authristn Any suggestions?
Answer: What about this: Auth'ze Auth'tion? We were tought to put aphostrophoes somewhere to shorten a word.

Question: As generally agreed and as extensively discussed in this question, "an" should be used in place of the more common "a" where the following word begins with a vowel sound. I have just encountered for the first time an instance of the phrasing an mule in the book Why Chemical Reactions Happen (James Keeler and Peter Wothers, Oxford University Press, 2003). (This book is not mine. I was sitting opposite a friend when the friend mentioned the unusual phrasing.) This phrasing appears to contradict the rule discussed above, since "mule" is, as far as I am aware, pronounced /mjul/ (see Wiktionary). Here is the context. The author is using an analogy to explain a chemistry concept (the italics are not mine, but the bold emphasis is): A useful analogy here is that of an mule, which we get by crossing a horse with a donkey. To describe an mule as a horse or a donkey would be inaccurate and it certainly does not interconvert rapidly between the two! Rather we need to recognize that although an mule has parts that are reminiscent of a horse and parts that a reminiscent of a donkey, it is something altogether different. Looking for other examples online, I have managed to find one on Wikipedia's List of Siege engines. Discussing a Siege engine, the Scorpio: Similar to the ballista, but smaller. Was sometimes mounted on an mule-drawn cart. Other examples are difficult to find, but here's one from a user-posted question on Answers.com (referring, notably, to a kind of deer rather than the animal, a mule): Is an mule deer an omnivore? No. Mule deer are herbivores. ... What is going on? Is there an irregular pronunication of "mule" of which I am not aware? Is this some strange language quirk, some archaic spelling that I am encountering for the first time?
Answer: The original printing had "an ass" instead of "an mule". That error was not lost on the chemistry community. See, for instance, Krenos's 2004 review of the text in the Journal of Chemical Education: In Chapter 10, bonding in extended conjugated systems and resonance are introduced with the horse + donkey = ass analogy (it is likely the hybrid animal mule is intended instead of ass, however). It seems the editors subsequently made an error mistake.
