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
注意B和D的区别！！！！！
（而且最开始这题选错完全是没有读进去题导致的！！沉浸阅读+享受获取新知识+相信自己一定可以读懂）
题目说的是并不明确知道effluents导致了north sea
B被控制的这些物质确实可以引起damage（但目前还不确实能够damage就一定是这个物质产生的）
D被控制的这些物质确实可以reach到north sea（可是，如果这些物质根本就不会导致damage，那这些restrictive controls就确实excessively了）
