Explanation
Choice D is the best answer. The convention being tested is the use of punctuation within a sentence. The comma after “swimming” pairs with the dash after “ciliates” to offset the supplementary element (“widely…ciliates”) that interrupts the main clause of the sentence. Choice A is incorrect. Adding the verb “is” here creates an ungrammatical sentence structure with two main verbs (“is” and “bestows”) without appropriate punctuation and/or conjunction. Choice B is incorrect because it fails to offset the 14 SAT PRACTICE TEST #11 ANSWER EXPLANATIONS SAT ANSWER EXPLANATIONS n READING AND WRITING: MODULE 1 supplementary element with appropriate punctuation.
