In 1959, the ﬁlm industry debuted Smell-O-Vision. Theaters were ﬁtted with specialized vents that emitted odors at speciﬁc
points in a ______ as the scent of roses when roses appeared in a scene. Smell-O-Vision failed to impress, however, with one
reviewer declaring it “brieﬂy weird and not very interesting.”

Choice D is the best answer. The comma appropriately separates the nonessential descriptive aside "such as…scene" from
the independent clause "Theaters were…movie." Since the descriptive example of roses isn’t necessary for the sentence to
function, it needs to be set off with punctuation.
Choice A is incorrect. This choice results in a run-on sentence. Since the example of roses isn’t necessary for the sentence
to function, the descriptive aside "such as…scene" needs to be separated from the preceding independent clause with some
sort of punctuation. Choice B is incorrect. This choice creates a punctuation error. A semicolon can only be used to separate
two independent clauses, but "such…scene" is not an independent clause and couldn’t stand on its own as a sentence.
Choice C is incorrect. This choice results in a sentence fragment. The descriptive aside "Such…scene" is not an independent
clause and can’t stand on its own as a sentence.
