Which best identifies the adverb clause?

A. No, I haven't been to a museum since my family moved here.

B. You should come with my family and me to see it.

C. There is an interesting exhibit right now about Native American artifacts.

D. Have you ever been to your local historical society?

A. No, I haven't been to a museum since my family moved here.

Explanation:

In A, the adverb clause is since my family moved here. It is an adverbial clause of time because it is introduced by a subordinating conjunction of time (since). It tells us about the time connection between the actions in the main and dependent clauses.

B is a simple sentence as it contains only one independent clause.

C is a simple sentence as it contains one independent clause.

D is a simple sentence, too, as it also contains only one independent clause.
