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
演绎推理
处理污水（保护环境）采用统一控制，不管特别的破坏是否由特别的污染物引起，为了不过度控制，需要注意：
A、所有统一控制都可能即刻施行（强调及时性，与过不过度控制无关）
B、所控制的物质确实对环境造成污染，CORRECT（为了不过度）
C、喜欢统一控制的国家是污水排放量最大的，与过不过度控制无关（因为统一有可能统一的小了（这样就有污水没被控制），也有可能统一的大了（这样就有可能过度，存在歧义，故不选）
D、要被控制的污染物已经到了北海；没有B好
E、北海的污染是可逆的，与过不过度控制无关
