标题: 求助一道逻辑题！

In setting environmental standards for industry and others to meet, it is inadvisable to require the best results that state-of-the-art technology can achieve. Current technology is able to detect and eliminate even extremely minute amounts of contaminants, but at a cost that is exorbitant relative to the improvement achieved. So it would be reasonable instead to set standards by taking into account all of the current and future risks involved.

The argument given concerning the reasonable way to set standards presupposes that

A.industry currently meets the standards that have been set by environmental authorities

B.there are effective ways to take into account all of the relevant risks posed by allowing different levels of contaminants

C.the only contaminants worth measuring are generated by industry

D.it is not costly to prevent large amounts of contaminants from entering the environment

E.minute amounts of some contaminants can be poisonous

答案是b，有没有nn可以帮忙梳理一下逻辑链啊？

这个题的结论是这是不明智的balbalab，还是最后一句话啊。

求解答～

在设定environmental standards上，要求达到现有科技可以实现的最优结果是不明智的。因为现有科技可以检测出哪怕极微量的污染，但成本相对于成效来说太高了。

结论：所以，instead , 在设定标准的时候应该把目前的，将来的所有风险都考虑进去

问；argument presupposes?

结论说应该 bla bla ,那assumption 就是bla bla 是可以达到的

这里的bla bla就是 taking into account all of the current and future risks involved

如果这个不成立的话，整个argument 就垮了

废话了半天说应该咋样咋样，结果这个咋样都无法操作，实现
