What is wrong with these sentences.
1.A copy of Moby Dick and a magazine has disappeared from my room.
Not only the muffler but also the spark plugs need to be replaced.
I am wondering what is wrong in each of these sentences.
Two things disappeared from your room. Would you say "they has disappeared" or "they have disappeared"?
The construction, "not only . . . but also," takes a singular verb. Would you say "it needs to be replaced" or "it need to be replaced"?
