I have written down a set of similar sentences below.
(1) There are no lights in the storage room and in the living room.
(2) There are no lights in the storage room and the living room.
(3) There are no lights in the storage and living rooms.
(4) There are no lights in the storage room or in the living room.
(5) There are no lights in the storage room or the living room.
(6) There are no lights in the storage room or living room.
I have come up with different possible ways to express the same thing.
Please note that I am using "in/the" twice in both (1)&(4), only "the" twice in both (2)&(5), and "the" once in both (3)&(6). In addition, I am using "and" in the first three and "or" in the next three.
All my friends and I are non-native English speakers. My sentences sound OK to all of us.
Which ones are idiomatic to native speakers?
