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.

Example Input: Question: I am looking for a derogatory term that can be used to describe a novice soldier/conscript who is awful at army-stuff. Something like cannon fodder but it should stress the incompetence of the described person, but it can't be a vulgarism. It is meant to be a unit name for a game set in a fantasy-medieval setting.
Answer: I've heard my military friends use FNG.
Example Output: no

Example Input: Question: When a user wants to delete something on a website, I would like to display a message for him/her to confirm. Which of the following is the grammatically correct way to say so? Are you sure to delete this item? or Are you sure you want to delete this item?
Answer: Are you sure to delete this item? Sure means "certain, without doubt". Therefore this asks if they are definitely going to delete the item. This isn't something to ask the user; if anything it's something for the user to ask about the program; "will it definitely be gone". Are you sure you want to delete this item? This asks not about what will happen (which is a question about the program) but what is desired (which is a question for the user). This is the one to go for.
Example Output: yes

Example Input: Question: Ok, if I say "this car is too expensive" or "this car is very expensive", then I can not express the connotation of "expensive". However, if I say "this car is damn expensive" then I better convey the connotation of "expensive". So my question is: What is the English idiom about "expensive" that expresses the idea that "It is so expensive that you feel like you got ripped-off and/or overcharged and/or unmeaningfully expensive"? For example, "damn expensive" could be ok but is there any other term?
Answer: stiff v. Usually applied to describe "to fail or refuse to tip a server," to stiff also means more generally "to cheat someone out of money." e.g. You said your brother-in-law would give me a fair deal, so I was surprised that he would stiff me out of so much money.
Example Output:
no
