找了很久没看到有问这题的，还是来自powerscore,俺见一题错一题，很受伤，擦擦眼泪，再来问大牛，拜托请指教！！！
查了国外网站有问这道题的，也是错误一片，标准答案是D，可是怎么觉得D提到的paper, glass, and metal 也不能说不是塑料就是这些吧？
好吧，我知道肯定是我思路不对，有谁知道怎么理解D是正确答案？？？help!

Waste management companies, which collect waste for disposal in landfills and incineration plants, report that disposable plastics make up an ever-increasing percentage of the waste they handle. It is clear that attempts to decrease the amount of plastic that people throw away in the garbage are failing.
Which one of the following, if true, most seriously weakens the argument?
(A) Because plastics create harmful pollutants when burned, an increasing percentage of the plastics handled by waste management companies are being disposed of in landfills.
(B) Although many plastics are recyclable, most of the plastics disposed of by waste management companies are not.
(C) People are more likely to save and reuse plastic containers than containers made of heavier materials like glass or metal.
(D) An increasing proportion of the paper, glass, and metal cans that waste management companies used to handle is now being recycled.
(E) While the percentage of products using plastic packaging is increasing, the total amount of plastic being manufactured has remained unchanged.

这道题好阴险。。看了半天醒悟。

D的意思就是说，An increasing proportion of the paper, glass, and metal cans that waste management companies used to handle is now being recycled.
wastes other than plastics都被回收再利用了，那么那些wastes就不可能进入 landfills and incineration plants。所以plastics make up an ever-increasing percentage of the waste they handle，换句话说，就是说本来全部垃圾是由塑料，纸张，玻璃组成。现在纸张，玻璃都能回收利用了，自然塑料所占的比例就上升了。

他因削弱。不一定是人们丢得塑料多才造成塑料占的比例多。

谢谢你的点拨yeah529, 是的做的时候怎么也想不明白,现在清楚了,的确是她因削弱.

他是说由塑料回收减少推行回收利用的计划失败，weaken说其他的材料回收增加了，也就是说所料回收减少是有其他的原因造成的，所以计划不一定失败了。

It is clear that attempts to decrease the amount of plastic that people throw away in the garbage are failing.

因为argue的是amount,所以能weaken的对应是数量方面的东西，否则没有可比性，故排除a,b,c. 再看E说法不对，所以只能选d
