Many people suffer an allergic reaction to certain sulfites, including those that are commonly added to wine as preservatives. However, since there are several wine makers who add sulfites to none of the wines they produce, people who would like to drink wine but are allergic to sulfites can drink wines produced by these wine makers without risking an allergic reaction to sulfites.
Which of the following is an assumption on which the argument depends? A. These wine makers have been able to duplicate the preservative effect produced by adding sulfites by means that do not involve adding any potentially allergenic substances to their wine. B. Not all forms of sulfite are equally likely to produce the allergic reactions. C. Wine is the only beverage to which sulfites are commonly added. D. Apart from sulfites, there are no substances commonly present in wine that give rise to an allergic reaction. E. Sulfites are not naturally present in the wines produced by these wine makers in amounts large enough to produce an allergic reaction in someone who drinks these wines. 题目就是说,一些人对wine里含有的sulfites过敏,而sulfites是防腐剂,所以他们会选择不含有sulfites的wine来喝
我选了A,这些制造商可以复制由sulfites带来的防腐作用,靠添加一种不会引起过敏反应的物质。
我是这样理解的,所有的wine都必须要添加防腐剂,否则就会很容易变质,而这些不添加sulfites的制造商依靠添加不会引起过敏反应的物质来充当防腐剂的,所以要选A
