OG详解-OG6 文法 Q6

Choice C is the best answer. The convention being tested is punctuation between sentences. In this choice, the period is used to correctly mark the boundary between one sentence (“Jamaican…microsculptures”) and another (“Creations…strands”). The noun phrase beginning with “creations” modifies the subject of the next sentence, “Wigan’s sculptures.”
Choice A is incorrect because it results in a run-on sentence. The sentences (“Jamaican…microsculptures” and “Creations…strands”) are fused without punctuation and/or a conjunction. Choice B 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 D is incorrect. Without a comma preceding it, the conjunction “and” can’t be used in this way to join sentences.
