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
