求分析OG对一道错误选项的解释-可生物降解和不可生物降解那题

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.

我的逻辑链：
C：可生物降解的plastic refuse(垃圾、废物)≥非生物降解的plastic的
P1：可生物降解的plastic中含有两种东西，一种是small bits，一种是bonding agent.
P2：只有bonding agent可以降解，而small bits会被剩下来

GAP: 如果是相同多少的可降解和不可降解的塑料包装，那么因为可降解的包装中的bending agent部分可以降解掉，那么剩下来的废物就会比完全不可降解的少。但这里要至少一样，那么可降解的塑料包装就要用更多的塑料材料。

求解惑OG对A选项的解释：

Both partially biodegradable and nonbiodegradable plastic beverage containers can be crushed completely flat by refuse compactors. OG：Nonbiodegradable plastic containners 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.
这里有个隐含前提“可生物降解的塑料不那么容易被压扁吗？因为材质的问题？然后只有他们含有的plastic少才能被同等程度地压扁？“

小妹先拜谢啦~~~~

嘿嘿，你自己有假设 额外的信息。 这个是不需要的 。

那为什么都能同样被压扁，biodegradable的塑料含量要少呢？？
