意思是理解了,但就想不通为什么答案是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.
意思是生产可降解塑料瓶所用到的塑料其实比不可降解塑料瓶药多,因为粘合剂的效果不够。
argument是当可降解饮料罐被废弃时,每个饮料罐产生的塑料废物一点也不少于不和降解的饮料罐
为什么B强化了这个argument呢?
