OG 12-51 谢谢大家

51. 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.



答案是B,请各位大牛们解释一下。。。谢谢

两种饭盒: A饭盒是聚乙烯做的, B饭盒是聚乙烯加玉米纤维做的. 当它们扔掉土里的时候玉米纤维被降解了, 聚乙烯都留着. 所以B饭盒也会造成污染. B选项说, B饭盒的制造需要比A饭盒的聚乙烯更多, 所以加强了原文的结论, B饭盒的污染甚至比A的更大
