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.
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: anchoretes 时间: 2011-2-8 20:30
