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: English isn't my mother tongue, and when we recently talked to a native speaker (during some company audit), he pointed out that the plural word "trainings" is actually wrong (he pointed that it is a very common mistake and was almost amused by it). I couldn't understand why and wondered what the correct plural of "training" would be. Online Dictionaries/Thesaurus don't answer it, so it's probably another opinion-based statement. I haven't found a source to back it up, though. 
Answer: Training is both countable and uncountable. Usually, referring to a process, it is uncountable and has no plural. It is sometimes used to mean "a specific training event", and is then countable, and has the plural "trainings". The OED has examples of this use going back to 1578, with the plural recorded from 1598.
[EX A]: yes

[EX Q]: Question: I am referring to someone who makes people 'buy' what he says and gets things done by them through nothing but clever speech something one can describe as crafty or beguiling, but not fraudulent. I pondered over con man and con artist for a while but those terms seem to hold a hint of crime, so those terms won't fit in. I am wondering if there is a more suitable phrase or word. 
Answer: If you seek a definition with some connection to cult of personality I'd suggest "Svengali" and "Mesmerist." A bit obscure but they also provide some panache. It's also fun to make people look things up.
[EX A]: no

[EX Q]: Question: Suppose there is a long sentence like: This London hit show took America by storm, full of charm, humour and delightful songs that make it a perfect theatrical event for the entire family. And you want to cut it off after an arbitrary specified amount of characters like so: This London hit show took America by storm, full of charm, humour and delightful songs that make... What is the name for the missing text indicated by the three-dot ellipsis? 
Answer: So you're talking about the "film on the editing room floor" is that right? Note that very often with single-word-requests, the correct answer is simply "there's no such word." In this case, the correct answer is simply "there's no such word." Note too that the situation can vary greatly: the ellipses in DH Lawrence's, err, 2nd? version of Lady Chatterly's Hot Lover, simply meant he never wrote them. Other times like when I quote from references the ellipsis means "the quotor left it out to save space" - and so on. There wouldn't really be one term for these vastly different, err, concepts ("never-written text" "swear words" "boring stuff" etc.).
[EX A]:
no
