OG12 CR51, A选项的解释

51. 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.

答案是B, 但是不理解对于A选项的解释,个人认为A选项是无关项,但是不理解GMAC为什么说“To say that biodegradable ones can be completely crushed also is perfectly compatible with saying that they contain less ”

OG解释: A Nonbiodegradable plastic containers can be crushed completely fl  at. To say that biodegradable ones can be completely crushed also is perfectly compatible with saying that they contain less plastic.

我表示没看懂A选项什么意思

就当无关好了,什么都没有比较出来。

不是学物理的,不清楚含plastic的多少被垃圾车压平的情况会是怎么样。
不过从argument的角度来讲,不知道具体知识应该也能判断的。
argument讲的是可降解的plastic不比不可降解的少。
而B选项中就说可降解的plastic用的比不可降解的多,直接strengthen了。

我开始觉得OG的解释有点不恰当,这个应该是个无关选项,但是再想想,comletely flat可能是想说明这两种容器所包含的数量是相同的,那可分解的因为是两种成分共同组成,那么也就是说它所包含的塑料成分应该比不可分解的少

嘿嘿,我是这样理解的,不知道有没有凭答案瞎想的云云~
