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. 这题完全没理解....此题选B....作者: 盛哥 时间: 2010-3-13 23:09
某一塑料瓶，由可降解和非可降解2部分塑料接合而成。题论点说丢弃此此塑料瓶后，仍有不可降解的部分，于是每个丢弃的瓶子最终都会剩下部分不可降解的塑料，且剩下的量要比完全普通塑料瓶的不可降解塑料的量要多。。。
