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 Q]: Question: In technical literature as well as aircraft user interfaces where there is not enough space to write the whole word, the prefix "trans" is shortened to "x". Transmit -> Xmit Transfer -> Xfer I am interested to know what is the origin of this. I am curious because "Ex" and "Trans" do not have a similar sound. 
Answer: In addition to the other edifying answers and comments: from an information-theory viewpoint, given the rarity of initial "x" in English words, the presence of it (especially if unpronounceable) is a clear signal that there is something at play slightly out of the ordinary, and it will not be easily mistaken for anything else. That is, information-theory-wise, the chance of misunderstanding is low (more technically/precisely, the error-correction properties of this usage are excellent).
[EX A]: no

[EX Q]: Question: What am I doing when I search for something on the internet and the search provides for some other interesting stuff apart from what I was looking for and I end up opening an infinite number of browser tabs and browsing more and more it goes in an endless loop and the whole episode makes for after thought to ponder upon. PS: I lost the term I had found on Wikipedia and I cannot get it back. 
Answer: XKCD calls this a "tab explosion".
[EX A]: no

[EX Q]: Question: My company is developing smart eyewear and I'm looking for a short word to describe the users of our smartglasses for English documents. The ideal wording would be understandable by British, US, and international audiences. It's primarily intended for internal usage, product specification, and exchanges with partners. It doesn't need to be formal; it can be some mild slang instead as long as it's generally friendly. We want to be able to use it openly in user documentation. It can't simply be 'users', because we also have other kinds of 'users' of our products who won't necessarily be using the smartglasses. So far I like the sound of 'speckies' or 'speccies' found in online dictionaries. Do they sound appropriate to you or would you have anything else to suggest? 
Answer: You could use myope. Obviously not everyone wearing glasses has myopia, but if you're just after a shorthand, this could suffice: A short-sighted person. -- Oxford Dictionaries.
