GWD4 - 40

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.

我选的D，给出的答案是E，谁来帮助解释下？谢谢。

without risking an allergic reaction to sulfites指出，没有加入添加剂的厂商的酒中“没有sulfites”。也就是说，assumption必须针对有没有"sulfites”，而不是其他成分。所以D错误。

E说，酒的自然成分中没有"sulfites"。

题干是针对peoplewho suffer an allergic reaction to certain sulfites，特指

而D给出的是give rise to an allergic reaction，对过敏的范指

相比之下，显然E更切中题目
