另外,为啥没有人关注In choices B and C, the preposition for is used unidiomatically in place of the "-ing" modifier to introduce the phrase describing powers 哪?是不是太简单了?为什么不能用for it to withhold哪?我觉得,表示赋予它这个Power的目的,也没什么不合适的呀?能否请哪位点拨一下。谢谢了。
from the logic point of view, it seems to me "discretionary powers" = can withhold public discolsure....(despite the "they" mistake here);therefore i can't see why the introduction of "that" clause in E)is MISTAKEN...(not less clear than A...)
