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 __________.



(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

請問為什麼是B呀 我選了B 可是我只是覺得他順眼 不知道為什麼~~~

  

請賜教

题干讲，控制effluents，whether or not specific environmental damage could be attributed to a particular source of effluent。无论effluents是否引起了某种环境破坏
问题是in order to avoid excessively restrictive controls, what should be showen ...为了不过分的控制，那只有区分控制对环境有破坏的effluents，B讲控制的substance 是应该能够影响环境的物质。符合

D为什么错？

试着解答一下，我本来也选了D，但是后来想想B是对的。

原文提议要total banned on effluents whether 他们是否造成了某种damage，但是又不能有不必要的controls，问怎么解决？

(B) any substance to be made subject to controls can actually cause environmental damage  以是否ACTUALLY造成污染为标准

(D) all of any given pollutant that is to be controlled actually reaches the North Sea at present 标准被narrowed，不能以现在是否到达了North Sea为标准，缩小了enviornmental damage的范围
