Which choice completes the text so that it conforms to the conventions of Standard English?
New York City.
that of New York City.

in New York City.
Correct Answer: B
Choice B is the best answer. The sentence compares the "public transit system" (singular) of Tokyo to the system of New York City. "That of" is the correct singular pronoun.
Choice A is incorrect because it compares a "system" to a "city." Choice C is incorrect because it creates a grammatically incorrect clause. Choice D is incorrect because "in New York City" is a prepositional phrase that does not act as a noun equivalent.
