E、an event that caused the plant and animal extinctions that mark
答案
E
解析
Logical predication; Agreement
This sentence describes a two-part sequence of events, the second of which has led to a particular categorization of geological time. In order to clarify that it is not the first event (asteroid strike) that produced the time division (end of the Cretaceous Period), but the first event’s consequences (biological extinctions), the sentence needs an appositive form to restate the content of the main clause (an event), followed by a two-part chain of relative clauses (that caused. .. that mark . . .).
A The antecedent for the relative pronoun which is ambiguous; it is therefore unclear what marks the end of the Cretaceous Period.
B The antecedent of which is unclear; the compound verbs caused and marks fail to indicate that the extinctions, not the asteroid strike, are significant markers of geological time.
C Following the conjunction and with a participial rather than a main verb is grammatically incorrect because it violates parallelism and produces a fragment at the end of the sentence.
D Which, referring to extinctions, should be followed by a plural verb.
E Correct. The sentence is unambiguous, an 1 the verbs agree with their subjects.
The correct answer is E.
