Mr. Luzaich created the seal to preven
参考解析：
C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。这个题目具有一定的迷惑性，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充入氩来防止变质，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“too gooey”），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，故选C。
