Which choice completes the text so that it conforms to the conventions of Standard English?
A
tombs. Built
B
tombs, built
C
tombs and built
D
tombs built
Explanation
Correct answer: A.
Choice A is the best answer. The convention being tested is punctuation use between sentences. In this choice, the period after “tombs” is used correctly to mark the boundary between one sentence (“Archaeologist...tombs”) and another (“Built...nature”).
Why the other choices are wrong
Choice B
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 C
Choice C is incorrect. Without a comma preceding it, the conjunction “and” can’t be used in this way to join the two sentences.
Choice D
Choice D is incorrect because it results in a run-on sentence. The sentences (“Archaeologist...tombs” and “Built...nature”) are fused without punctuation and/or a conjunction.
