Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no".

Example Input: Question: Possible Duplicate: "If I was" or "If I were". Which is more common, and which is correct? Is this correct grammar? What if there was a Stack Overflow on Shouldn't it be "what if there were a Stack Overflow on"? 
Answer: Prescriptively, you're correct, this should be were since this is being expressed with the subjunctive mood. Descriptively, I think you'll find both in the wild. In informal speech, most people I know would prefer was in this case (and those that don't are sticklers for the subjunctive). I do think that you are much more likely to see were written though, especially in formal writing. Either form is correct, and the subjunctive forms are far from dead. A more interesting question, I think, is whether or not the subjunctive mood is still being used and if the two forms have simply collapsed together. Is this a meaningful distinction? How could this be tested?.
Example Output: yes

Example Input: Question: I am developing some software where users are assigned tasks. They will see a date and time for when they were assigned to the task, but if they were later removed from the task, there will be a date and time for that also. 01/02/14 - Assigned 03/02/14 - Unassigned I'm pretty sure unassigned isn't correct. I suppose the task itself could be in a state of being unassigned, but the user wasn't "unassigned" from it. Notes: I don't want to use the word "removed", as I don't think it conveys the correct meaning and also sounds too harsh. I would like to avoid using a word your average person would never have heard of, as this isn't very user-friendly from a software point of view. 
Answer: "revoked", "withdrawn", "retracted", or simply "reassigned".
Example Output: yes

Example Input: Question: Any situation, any time; this person has always something negative to say about it. It should be a noun or an adjective to describe a person who is a damp cloud walking over every sunshine situations at the cubicle, hoping to drench other people with his miserable comments. I considered "sourpuss" but would prefer something more important sounding, like "misogynist." 
Answer: My favorite of all time comes from a Saturday Night Live character: Debbie Downer. Ever since, when someone's hellbent on constantly reporting about the sucky side of everything, you will often hear someone say to them, "Quit being such a Debbie Downer.".

no
