标题: OG12-51闹心 [打印本页] 作者: kobe198879 时间: 2010-11-10 20:41 标题: OG12-51闹心 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.
上段话中的论据和结论是什么啊？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.
这句话表达的到底是什么意思，since在这里是什么意思，B选项如何加强这句的丫？作者: sdcar2010 时间: 2010-11-10 21:46
The clause SINCE gives a reason, followed by the final conclusion that the new type of containter has no less plastics than the old one: either the same or maybe more.
B says that the new type contains more plastic than the old one.作者: gkast 时间: 2010-11-11 00:28
