标题: 逻辑大全,GMAT部分TEST 7的No. 14
14.   Which of the following best completes the passage below?

At a recent conference on environmental threats to the North Sea, most participating countries favored uniform controls on the quality of effluents, whether or not specific environmental damage could be attributed to a particular source of effluent. What must, of course, be shown, in order to avoid excessively restrictive controls, is that______


(A) any uniform controls that are adopted are likely to be implemented without delay

(B) any substance to be made subject to controls can actually cause environmental damage

(C) the countries favoring uniform controls are those generating the largest quantities of effluents

(D) all of any given pollutant that is to be controlled actually reaches the North Sea at present

(E) environmental damage already inflicted on the North Sea is reversible


本题答案是B,B是可以的;但D为什么不对呢?完成段落的部分应当表达的是一个能够(“避免过度限制”)“avoid excessively restrictive controls ”方案,D中的方案是仅对"reach North Sea"的污染物进行控制(对于没有"reach North Sea"的,可以不控制),不正是一个(“避免过度限制”)“avoid excessively restrictive controls ”的方案吗?

B肯定没问题的,防止错杀。但是D说仅仅限制当前出现的污染物。但是注意,这里和B不一样,说的是pollutant,也就是说已经明确知道是污染物了,那么即使他现在没有出现,也应该控制,防止出现,因为一旦出现,环境又将遭到破坏,这个属于防患于未然,不能算过度限制!

有道理,谢谢!
