prep1-61关于环境污染

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

选的时候在B，E上纠结，请大牛指导！小女子不胜感激

B正确，原文是问：为了防止过度严格的控制，什么是该明确的？B是说：控制物确实是有损环境的。如果不损害环境也被控制了，就是过于严格了。 

E是说：已经在北海造成的环境损害是可逆的。这个和过度严格的控制有什么关系呢？可逆不可逆和控制的严不严都没有关系。思维一定不能有随意的跳跃。

不是大牛，仅供参考。

我觉得应该选B，此道题目可以理解为削弱题，即选项推翻原文的观点，而E是事实陈述，不应列入。其他选项有的是支持，不应考虑。

个人意见，请牛人指点！

同意三楼意见，我也觉得选B
