这个OG题我看不懂意思,有谁帮忙翻译一下,再解释一下就更加感激了。 OG11-53:one variety of partially biodegradable beverage container is manufactured from small bits of plastic bound together by a degradable bondiing 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 ture, most strengthens the argument above? B. the partially biodegradable plastic beverage containers are made with more plastic than comparable non-biodegradable ones in order to compensate for the weakending effect of the bonding agents.
