84. 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 sulfites 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 sulfite are equally likely to produce the allergic reaction.
(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 winemakers in amounts large enough to produce an allergic reaction in someone who drinks these wines.

答案是E 我觉得也对但是我觉得为什么D不对如果把D取反那么能够对原文结论产生影响

D是无关项了. 题干一直在说sulfites.没有提到其它的东西.

原文结论中提到的是without risking an allergic reaction to sulfites
所以即使存在其他的allergic reaction也不会削弱原文结论，因为原文结论根本就没有提到其他的allergic reaction
