Every Bentley, Lamborghini, and Porsche (is/are) owned by Volkswagen
I had some difficulties with this because I thought that the answer would have to be "are" because a) There are different objects that are being listed out
b)"every" signifies multiple things so I thought that it would entail that I ought to choose "are"
But the answer key dictates that the answer is "is" and I don't understand why that is.
I was wondering if it has to do anything with the word "every"?
