C) Since they erode statues and corrode steel structures, the chemicals in acid rain are harmful.

I know it is not c or a. But I think it is d.

Answer 1

Complex sentence = 1 independent clause + at least 1 dependent clause

The intro words "since" and "even though" usually introduce dependent clauses -- <b>IF</b> there's a subject and verb that go with it.

In which sentence is there NOT a subject and verb that go with "since"?
