Many people suffer an allergic reaction to certain sulfites,including those that are commonly added to wine as preservatives.However ,since there are several winemakers who add sulfites to none of the wines they produce ,people who would like to drink wine but are allergic to sulfits can drink wines produced by these winemakers without risking an allergic reaction to sulfites. Which of the following is an assumption on which the argument depends? A these winemakers 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 sulfit are equally likely to produce the allergic rection. 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 presentin the wines produced by these winemakers in amounts large enough to produce an allergic reaction in someone who drinks these wines. 答案是E 我个人觉得D选项也是对的 亦或者两者都对 只是E更好,如果是的哈 为什么呢? 谢了 |
