问题
According to Gregory Luzaich. the disadvantage of modest drinking is______.
Mr. Luzaich created the seal to prevent the wine from declining with______.
选项
A、neoprene
B、visco-elastic polymer
C、silicon
D、argon
答案
C
解析
事实细节题。题目,问的是Luzaich先生创造的防止酒变质的盖子是什么做的。这个题目具有—定的迷惑性,因为全文讲的是防止酒变质的设备,而不是单独的盖子,这个设备的主体原理是注入氩来防止变质,但是盖子的材料却不一样。全文有几处提到,第二段一开始"before sealing it airtight with silicon",第四段"He experimented with several substances,from neoprene to a visco-elastic polymer (which he dismissed as "toogooey"),before settling on a food-grade silicon."(他试验了几种材料,从氯丁橡胶到黏性聚合体(他觉得"太黏了"所以没用),最后选定了食品用硅)。因此,做盖子的材料是硅。
