有人能帮我把题干的意思表达一下吗？我不明白问题让削弱提干中的那一部分，题干争论的什么呀？谢谢！

124. It is repeatedly claimed that the dumping of nuclear waste poses no treat to people living nearby. If this claim could be made with certainty, there would be no reason for not locating sites in areas of dense population. But the policy of dumping nuclear waste only in the more sparsely populated regions indicates, at the very least, some misgiving about safety on the part of those responsible for policy.

Which one of the following, if true, would most seriously weaken the argument?

(A) Evacuation plants in the event of an accident could not be guaranteed to work perfectly except where the population is small.

(B) In the event of an accident, it is certain that fewer people would be harmed in a sparsely populated than in a densely populated area.

(C) Dumping of nuclear waste poses fewer economic and bureaucratic problems in sparsely populated than in densely populated areas.

(D) There are dangers associated with chemical waste, and it, too, is dumped away from areas of dense population.

题干说一直以来都说倾倒核废料对周围居住的人没有害处。於是有人站出来说话了：如果真的对人没什么坏处，为什么核废料都是丢到人烟稀少的地方呢？你看现在核废料还是倒在荒蛮之地，可见这个说核废料没有坏处的政策还是有点不把人民安全当回事儿的。题目问哪个反驳这个结论。(结论说政策是不好的，没有考虑安全问题。) 我选C，C的意思是用它因削弱，即把核废料倒在荒凉之地是别的原因：经济和政府的原因，而非安全问题。

那﹙E﹚呢?我觉﹙E﹚也是一个好答案啊!提出了其它原因来weaken原论题的说法。教教我吧!

﹙E﹚Until there is no shred of doubt that nuclear dumps are safe, it makes sense to situate them where they pose the least threat to the public.

E还是说明因为安全问题不能保证，才把地址搬到对公众威胁较少的地方。

(A) Evacuation plants in the event of an accident could not be

guaranteed to work perfectly except where the population is small.

只有在周围人口较少的情况下, 核工厂的撤离才有可能安全工作.

还是强调安全问题.
