标题: OG 12 -- CR 51答疑

one variety of partially biodegradable plastic beverage container is manufacttured 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.

答案 INCORRECT

Nonbiodegradable plastic containers can be crushed completely flat.To say that biodegradable ones can be completel crushed also is perfectly compatible with saying that they contain less plastic.

同志们帮我解释下OG的答案好吗?看不懂A选项的答案.

谢谢大家

原文: only bonding agent degrades --> biodegradable 不比 nonbiodegradable 产生的塑料废弃少

gap: biodegradable 与 nonbiodegradable 的塑料含量

选项A)无关

OG的解释是biodegradable能被彻底压扁可能是因为塑料含量较少(不能说明no less)

顾客喜不喜欢没有关系呀，这里只是在比较biodegradabie和nonbiodegradabie的塑料含量
