标题: OG11-53(E選項) [打印本页] 作者: Kath1985 时间: 2010-4-11 16:11 标题: OG11-53(E選項) 53. 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 partially biodegradable plastic beverage containers rather than in nonbiodegradable containers, even if the price is higher. (D)The manufacturing process for partially biodegradable plastic beverage containers results in less plastic waste tan the manufacturing process for nonbiodegraable 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B 請問E是什麼意思 不明白 作者: prayer 时间: 2010-4-11 16:25
E说现在的循环回收的科技问题不会回收任何形式的塑料做食品和饮料包装。 题目的结论是，可降解的塑料容器比不可降解的塑料容器产生的塑料不少。题目要求加强的是塑料多。 E只能说跟题目无关，没提到回收利用。作者: Kath1985 时间: 2010-4-19 20:25
