On their "European Architecture Tour," the students visited three of the continent's most famous (and most photographed) ___________ the Eiffel Tower, the Colosseum, and the Parthenon.
Which choice completes the text so that it conforms to the conventions of Standard English?
landmarks:
landmarks,
landmarks;
landmarks
Correct Answer: A
Choice A is the best answer. A colon is used to introduce a list that renames or explains the noun phrase "three of the continent's most famous... landmarks."
Choice B is incorrect because a comma creates a run-on sentence. Choice C is incorrect because a semicolon cannot introduce a list. Choice D is incorrect because punctuation is required to separate the main clause from the list.
