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

答案b

答案b

我认为原文中已经有说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. 所以将b排出了

不了解为什么会这么错 =.=

查过记录没有人解释过。。

个人理解:

要防止过度的限制，因此必须要证明“任何需要被控制的东西都会对环境

造成实质性的破坏”——B选项其实是很完美的答案。
