Hi, I have a quick question about the SAT, which I am taking a week from today. The grammar section of my reviewbook (Princeton Review) says that the pronoun "none" is always singular (ie. "None of the people is going to the party"). This seemed weird to me, so I asked my English teacher and she said that "none" can be singular or plural depending on the context (ie. "None of the food is rotten" versus "None of the people are going to the party"). I think my English teacher is probably right, but since my review book is tailored for the SAT, I'm nervous about what the SAT graders consider the correct answer to this question. Does anyone happen to know this?
