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 __________.
any uniform controls that are adopted are likely to be implemented without delay
any substance to be made subject to controls can actually cause environmental damage
the countries favoring uniform controls are those generating the largest quantities of effluents
all of any given pollutant that is to be controlled actually reaches the North Sea at present
environmental damage already inflicted on the North Sea is reversible
根据结论的特殊性和具体性——不过分限制管控，可以明确排除A,C,E,
对比B,D，做题时我无法明确的分辨，所以随机选择D，导致错误
这道题不属于常规GMAT CR题型，只能从内容上分析
B,只管控污染物，具有明确性
D，污染物到达与否，这只是有可能达到目的，万一虽然污染物没到达，但通过各种间接途径仍然影响北海，所以加强失败
