"Are" refers to multiple things, while "is" refers to a single thing. For example; "all five cats are flying" is correct because it uses "are" to refer to multiple things, whereas "all five cats is flying" is incorrect. "This question is about grammar" is correct, since it's talking about one question, while "This question are about grammar" is incorrect. Also, "are" and "is" are both present tense words, so don't use them to refer to something that already finished happening or something that hasn't started happening yet.
