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.

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: I agree with Mick that training is an uncountable noun. In the example given by Mr. Fine of a specific training event allowing training to become countable, I disagree. In the case of becoming countable, the portion being counted is the event. Therefor, it would be "there are multiple training events available at the pavilion" (or whatever). I see many cases where much effort is made to "fix" the plural when a simple rewording will eliminate the contentious context and allow an, arguably, better flow by using the standard form.

Q: Question: I'm a programmer and often create login/register forms. I'd really like a single word to use to describe a form that lets the user login/register. Sort of like "authentication", but that's really more specific to the login part. The next best I can come up with is "onboarding", but that really applies more to the register part. Does such a word exist? Edit: I'm really looking for this from a coding perspective, not to display on the page (i.e. it doesn't need to be user-friendly). I just want it to be concise so that I can avoid variables like "login_register". 
Answer: access make session authentication auth SSO join & connect.

A: no

Q: Question: What is the idiom for a situation that "If people-in-authority don't follow their own set rules, then what can one expect from rest of us" in similar examples given below in different settings: When HR themselves are tardy, undisciplined then what can you expect from the employees (punctuality and discipline)? When traffic police themselves are offending (driving without belts, smoking while driving) what can you expect from the vehicle driving community in the city? When parents themselves are undisciplined (smoking in front of children), what can you expect from the children themselves? When the management is insincere, what can you expect from their staff? 
Answer: While not an exact fit (because it doesn't necessarily involve figures of authority), what about the following: If they don't practice what they preach why should we? from def: To do the things that you advise other people to do: He's such a hypocrite! He never practises what he preaches. (Cambridge) Also, while not an idiom, hypocrite fits as well.

A:
yes
