1. Following the destruction of the space shuttle Challenger, investigators concluded that many key people employed by the National Aeronautics and Space Administration and its contractors work an excessive amount of overtime that has the potential of causing errors in judgment.
(A) overtime that has the potential of causing
(B) overtime that has the potential to cause

欧第一次作的时候选了e,第二次作的时候对og的解释记忆深刻，选了d,结果错了，请看og的一道题目：
159. While depressed property values can hurt some large investors, they are potentially devastating for home-owners, whose equity—in many cases representing a life’s savings—can plunge or even disappear.
(A) they are potentially devastating for homeowners, whose
(B) they can potentially devastate homeowners in that their
(C) for homeowners they are potentially devastating, because their
(D) for homeowners, it is potentially devastating in that their（A）
(E) it can potentially devastate homeowners, whose
Choice A is the best. Its wording is unambiguous and economical. The plural pronoun they agrees with its antecedent, property values. The pronoun whose clearly refers to homeowners and efficiently connects them with the idea of lost equity. In B, C, and D, substituting in that their or because their for whose is wordy and confusing since the antecedent of their might be they, not homeowners. Furthermore, can potentially is redundant in B and E. Both D and E use the singular pronoun it, which does not agree with its logical antecedent, property values.
但是在大全300，这道题的答案和og这题的解释似乎有不同，请教如何区别呀？ |
