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 an given pollutant that is to be controlled actually reaches the North Sea at present
(E)environmental damaged already inflicted on the North Sea is reversible
排除掉B的原因是，“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.”这句话我认为是一个Premise,意思是无论环境问题是不是由某一种污染物引起的，所有参会国家都支持统一的控制，B又刚好是和这句话意思相反。不是说一般逻辑题不会去攻击Premise吗？所以我绕开了这个选项。
