7.     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.（D）

(E) While the percentage of products using plastic packaging is increasing, the total amount of plastic being manufactured has remained unchanged.

这题答案是（D），没什么疑问，只是还没怎么想明白（E）错在哪里呢？

根据（E）所说，用plastic包装的the percentage of products正在上升，但是plastic的生产总量目前却remained unchanged，所以导致人们购买的产品用plastic包装的增多，所以进而人们扔的也就很多，所以也就加强了原文的结论？

是这样想的吗？the total amount of plastic being manufactured has remained unchanged在（E）选项中又起着什么作用呢？

嗯，没想通呢，请nn指点

e is a trick. you cannot infer anything about change of plastic waste.

It's the percentage not the amount of products that E is talking about.
