Is it possible to say "You can't shut up everyone in this room"? Or should it be "You can't shut everyone up in this room?
I may be the only person that thinks this, but to me:
You can't shut up everyone in this room = You can't make all the people in this room stop talking or making any noise.
You can't shut everyone up in this room = You can't enclose all of these people in this room and then close/lock the door.
