writingWhich choice completes the text so that it conforms to the conventions of Standard English?
A
hydroelectricity—especially the latter
B
hydroelectricity—especially the latter,
C
hydroelectricity especially the latter,
D
hydroelectricity—especially the latter—
Correct Answer: D
Choice D is the best answer. The phrase "especially the latter" is an interrupter emphasizing the last item in the list. Since it starts with a dash, it must end with a dash to be grammatically consistent.
Choice A is incorrect because it lacks closing punctuation. Choice B is incorrect because it pairs a dash with a comma. Choice C is incorrect because it lacks the opening punctuation.
