[color=red]1-The computer in each of those rooms is new.
[color=indigo]2-The computers in each of those rooms are new.
[color=red]3-The computer in all of those rooms is new.
[color=indigo]4-The computers in all of those rooms are new.
Which ones should one use if there is only one computer in each room?
ı think 1… is right?
me too think it correct
the first
the first is correct
#1 is correct. One comp in each room.
#2 is correct. More than one comp in each room.
#3 is wrong. Only one comp can not exist in more than one room.
#4 would be right without “of”. a bit ambiguous for we do not know how many of them is in every room.
That is my opinion.
‘of’ is acceptable in 4 though you are right that it would also be correct without the preposition.
Thank Coach!
