Goa _______ was a Portuguese colony until 1961.
Which choice completes the text so that it conforms to the conventions of Standard English?
a state on India's western coast
a state on India's western coast,
a state, on India's western coast,
a state on India's western coast:
Correct Answer: B
Choice B is the best answer. The phrase "a state on India's western coast" is a nonrestrictive appositive renaming "Goa." It provides extra information and must be set off by commas on both sides.
Choice A is incorrect because it lacks the necessary commas. Choice C is incorrect because the comma after "state" disrupts the appositive phrase itself. Choice D is incorrect because a colon is inappropriate here; the sentence continues after the appositive.
