“Bess, who can draw beautifully, loves art; but Grace, who thinks very logically, prefers science.” This is an example of which of the following sentence structures?

This is an example of a compound-complex sentence, which combines two independent clauses with one or more dependent clauses. “Bess loves art” is an independent clause, modified by the dependent or subordinate relative clause “who can draw beautifully.” “Grace prefers science” is a second independent clause, modified by a second dependent or subordinate relative clause “who thinks very logically.” The two independent clauses are joined by the conjunction “but.” A compound sentence has two independent clauses but no dependent clauses. A complex sentence has one independent and one dependent clause. A simple sentence is one independent clause.
