 Isn't it, or are they?
Excuse the silly question, but I can't give another answer other than 'because it just is'. I was asked to about the following: "Isn't it aeroplanes that are mainly responsible for the pollution in the atmosphere?".
I guess the main reason for the question is, why is "it" used for earoplanes (plural), instead of 'are'? My reply was that it is a question and not a statement.
Can anyone help with this, in more technical term. Or, is it really as simple as 'because it is?' |
