OG 12TH-52有疑惑阿

One variety of partially biodegradable plastic beverage container is manufactured from small bits of plastic bound together by a degradable bonding agent such as cornstarch. Since only the bonding agent degrades, leaving the small bits of plastic, no less plastic refuse per container is produced when such containers are discarded than when comparable nonbiodegradable containers are discarded.

Which of the following, if true, most strengthens the argument above?

(A) Both partially biodegradable and nonbiodegradable plastic beverage containers can be crushed completely flat by refuse compactors.
(B) The partially biodegradable plastic beverage containers are made with more plastic than comparable nonbiodegradable ones in order to compensate for the weakening effect of the bonding agents.
(C) Many consumers are ecology-minded and prefer to buy a product sold in the partially biodegradable plastic beverage containers rather than in nonbiodegradable containers, even if the price is higher.
(D) The manufacturing process for the partially biodegradable plastic beverage containers results in less plastic waste than the manufacturing process for nonbiodegradable plastic beverage containers.
(E) Technological problems with recycling currently prevent the reuse as food or beverage containers of the plastic from either type of plastic beverage container.

OG解释如下

A Nonbiodegradable plastic containers can be crushed completely flat. To say that biodegradable ones can be completely crushed also is perfectly  compatible with saying that they contain less plastic.
B Correct. Th is statement properly identifi es a point that strengthens the argument by saying that the container actually produces more plastic refuse.
C Consumers’ preferences are not relevant to the argument about residual plastic.
D Th e argument is not concerned with waste from manufacturing processes, but only with the product itself.
E No reason is given to indicate that the inability to reuse the plastic from either type of container is related to the amount of plastic in either container.
The correct answer is B.

没怎么看明白.哪位nn解释一下哈

不知道你的疑惑是？

如果笼统的但就这道题来说的话，题干中给出了两个物体，一个是带有bonding agent的所谓的能够生物降解的塑料瓶子，另一个是不能降解的瓶子

抛开它的原文来看，说的这两种东西的其一是（biodegradable)：降解部分+塑料部分垃圾。另外一种(non-biodegradable)：塑料垃圾

说完了题干给的信息那么来看题目中的结论，结论说能够降解的产生的垃圾不少于（多于）不能降解的，从中应该可以觉得有一些不合理，合着我做出来的高科技产品都能降解一部分了最后还没有你原始的塑料罐子环保？

这时候把B拉进来看，就明了了，B说biodegradable为了装这个bonding agent得带有更多塑料，来compensate那个weakening effect（管它那个是什么效应），这样的话就算它的bonding agent能够消失，剩下的塑料也足够比不降解的容器多了，所以是B

解释的思路好乱，不好意思

哦，其实我的问题就没怎么把这篇描述读明白呵呵。。。谢谢解释。。我貌似明白一些了呢
