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
老师：这题我错选C，当时是这样想的：要求统一控制的国家是排放量最大的，如果要求统一控制是不是对排放的比较少的国家是excessively restrictive controls呢？
选项C的字面意思是：同意统一控制的国家是那些有最多支流的国家（注意，这里的词是quantities而不是quality）。这个选项和河流的质量没有任何关系。
