OG13th版本的CR50
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 bounding 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.
A.Both partially biodegradable and no biodegradable 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 no biodegradable 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 no biodegradable containers , even if the price is the higher.
D.The manufacturing process for the partially biodegradable plastic beverage containers results in less plastic waste than the manufacturing
process for no biodegradable plastic beverage containers.
E.Technological problems with recycling currently prevent the refuse as food or beverage containers of the plastic from either type of plastic
beverage container.
我自己选的是D，答案说是B…
按照题目的意思说cornstatch分解之后就剩下了一点点塑料残留物
