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
我那这道题解释题做，“不管是否是eflluents导致污染，当控制e的质量，其实我觉得选项中每一个能解释，就选了各有关键词的。。。。郁闷。。。。
