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（B）

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

请问D为什么错? 是错在"at present"吗?

答案是不是C呀,,

答案是B吧。

要治理environmental threats to the North Sea，先从quality of effluents，lz注意这句话：whether or not specific environmental damage could be attributed to a particular source of effluent；连是否有specific enviromental由effluent引起都不能明确，更别提 reaches the North Sea 了，D答案我觉得有没有at present都是错误的答案；

所以为了避免过分严格的control，只要能控制effluent里面确实能引起enviromental damage的物质就可以了（B),是否largest(C)都无关；

有人能解释为什么D是错的马。。
如果还要去管理那些根本还没有到达NORTH SEA 的物质，不也是管得太多了吗？

D错在at present
at present指开会时，但是在开会时并未达到北海并不一定就意味着将来不会达到。
本题的核心是过度管理，所以不过度管理的方式就是指管理那些会产生环境污染的东西。

the countries favoring uniform controls are those generating the largest quantities of effluents
这个更好

是不是错在all of any given pollutant 上啊~ 因为不是所有的污染物

都排向北海

题目中提倡联合管理洋流，而且说不管部分污染能不能溯源至一些特定的洋流，也就是说不管知道不知道是哪条洋游引起的污染，所有的洋流都要治理。但D中是说必须只管理那些流至北海的洋流，这与题干矛盾！
