Question

After the United Kingdom began rolling out taxes equivalent to a few cents on single-use plastic grocery bags in 2011, plastic-bag consumption decreased by up to ninety blank taxes are subject to what economists call the “rebound effect”: as the change became normalized, plastic-bag use started to creep back up.

Which choice completes the text so that it conforms to the conventions of Standard English?

Accepted Answer

Choice C is the best answer. The convention being tested is punctuation use between sentences. In this choice, the period after “percent” is used correctly to mark the boundary between one sentence (“After…percent”) and another (“Such…up”).

Choice A is incorrect because it results in a comma splice. A comma can’t be used in this way to mark the boundary between sentences. Choice B is incorrect. Without a comma preceding it, the conjunction “and” can’t be used in this way to join sentences. Choice D is incorrect because it results in a run-on sentence. The sentences (“After…percent” and “Such…up”) are fused without punctuation and/or a conjunction.
