问题 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?

选项 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 bounding 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、Technologica’ 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

解析 本题难点在于读题,注意段落中since后面的“only”以及“no less than”为“不少于”的意思。如果制造partially biodegraclable plastic beverage产生的塑料并不少于comparable nonbiodegradable containers丢弃时产生的塑料,正如(B)所说,那么结论“no less plastic refuse...are discarded”,可以得到很好地支持,所以(B)正确;(A)指出了两者的共性,但与“能否产生塑料”无关;(C)与“refuse”无关;(D)颠倒了两者关系,起到了反对作用;(E)与(A)一样,指出了两者共性,但并不能支持为什么有上述结论,因此(E)不正确。注:biodegradable adj.可被生物分解的,可由细菌分解降落的refuse n.废物,废料,垃圾
