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: What's the difference between these two phrases? 
Answer: The difference is pretty subtle, but the "did you..." version implies more of an event, i.e. something that needs to be seen just once, perhaps because it's temporary. So, Have you seen [insert movie title]? but Did you see last night's [insert TV show name] episode? Edit: note that there's nothing wrong with "Have you seen last night's episode?", or with "Did you see the movie?", but there is a (slight) difference in meaning.

A: no

Q: Question: Is the word "dude" becoming gender neutral? I don't think so, however, has modern usage changed? Are there some recent examples of "dude" being used to refer to a woman or group of women? 
Answer: Personally I would feel quite creeped out if a male individual would address me with dude and I have not seen the word dude used as a gender neutral term. If a female individual would address me with dude I think she could get away with it, but it's not something I have actually seen. A (female) friend of mine does use the terms dudette dudette (plural dudettes) (slang, often humorous) Term of address for a woman. (slang, often humorous) A cool woman, especially a surfer or skater. [...] and dudess dudess (plural dudesses) A female dude, i.e. a cool female. Although as stated this usage is often a bit joking and humours rather than serious. For that matter, it can also be pointed out that dude is still only defined as a male term in the dictionary I checked.

A: no

Q: 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: I've worked with IETF people and developers who spend a lot of time on Apache, who tend to use: AuthN - Authentication AuthZ - Authorization You'll find these abbreviations in a lot of IETF technical documents. Yes, I know British spelling prefers s over z (authorisation).

A:
yes
