OG-159

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.

这道题的B，ETS的意思是can不能和potentially连用吗？另外devastating后面为什么还要加 for，它不是及物动词吗？

can 与potentially确实不能连用，potential=capable of being used，所以不能连用，但大全补充里还有一题也考此点，好象是“can,potentially,－－”

至于devastate是及物动词，分析得真仔细啊，devastating好象也是adj
