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: "Polarizes" is not the right word for this. If you can imagine a group of people being strictly divided in opinion, the ideological line which divided them would be the thing I am trying to generically name. I'm looking for a specific word that I know I've seen before but can't remember. I've googled this but have not been able to find the right word. This is the best definition I can provide. An (poor) example is how a stance on taxes divides people into Democrats and Republicans 
Answer: It sounds like you are looking for the word issue: whether taxes should be equally applied to rich and poor, or scaled, is the issue that divides Democrats and Republicans.
no

Question: I understand what the idiom means: as per this question, it means a person or creature unwittingly used as a test for danger, often destructively. I understand why coalmines: as depositories of ancient organic waste, they are particularly prone to methane and carbon monoxide buildup. But why a canary? They are technically exotic, native and (at least originally) endemic to the sub-tropical Canary Islands, which gave them their name. They were also renowned for their singing voice, as found out in this answer, and could presumably be quite expensive. So why would a mining company in Britain and/or America and/or any other English speaking country use such an expensive and exotic bird as a glorified carbon monoxide detector whose sole purpose in life was to suffocate to death? Why wouldn't they use sparrows, or starlings, or some other small songbird native to the area? Are canaries just that easy to breed and keep? Are they super-extra-sensitive to poison gases and thus were the "upscale" model? Were all small, caged songbirds called "canaries" as a matter of course? Or did the modern idiom simply opt for alliteration over historical accuracy? 
Answer: Male canaries will sing all the time when they're alone in the hope of their song attracting a female. In fact, the main reason for them being held in captivity is their incessant song. This makes them ideal for coal mines; you don't have to concentrate on them or watch them. You do your work, register the canary's song as a background noise, and as soon as the background noise stops, you know you're in trouble.
no

Question: Is it correct to say "Wish you a happy weekend" or should I say "Wishing you a happy weekend"? 
Answer: Neither Wishing you a happy weekend nor Wish you a happy weekend would be used in normal conversation. As others have noted, spoken parting platitudes at the end of a week are normally started with have, such as: Have a good weekend Have a nice weekend etc. Change the adjective to be what you think most appropriate for the situation. On the other hand, if you are signing off some correspondence, such as an email, then Wishing you a happy weekend is more appropriate. Similar constructions include Wishing you a happy birthday Wishing you a merry Christmas Wishing you well To use *Wish you a happy weekend you need to add I to make the sentence grammatical. i.e. I wish you a happy weekend. A notable exception to this is the common postcard sign off Wish you were here where it is idiomatic to leave out the I.

yes
