标题: 一道加强题。。。。 [打印本页] 作者: xingxc11 时间: 2011-9-10 10:38 标题: 一道加强题。。。。 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 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. 这道题很懵啊 请各位帮忙分析一下作者: cdwayne 时间: 2011-9-10 13:17
原文說某用於連結的生物分解塑料由於比例低因此產生的垃圾並沒有比非生物分解的塑料來得低，(B)表示為了彌補其weakening effect還多加了一點
