题目是：
51 One variety of partially biodegradable palstic 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 dscarded than when comparable nonbiodegradable containers are discarded.
which of the following, if true, most strengthens the argument above?
