OG12 CR 几道问题纠结得很纠结得很纠结得很

照你说的，D的意思是酒中“除了sulfites”没有其他因素会引起过敏反应，但是不能保证酒里面不是直接带有sulfites啊。即便不“人为”掺杂sulfites，如果红酒本身就带有致敏源和足够的量（即E想排除的问题），那他们喝了还是会过敏的。

废话不多说了，直接上题：

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.
明白E选项是给出他因，但是不明白D错在哪里了，看到CD有资料分析说是“作者的结论只考虑sulfites和过敏的关系，不考虑其他”，可是从另一方面来说，如果酒中除了sulfites没有其他因素会引起过敏反应，那么不也会导致题中的结论正确吗？（即只要喝不掺杂sulfites的酒而改喝其他酒就能够避免过敏）？？？

楼主请仔细看题干，题干的原话是：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.
看见了吗？题干的结论是，people就喝这种酒就不会对sulfites过敏了。
但是D选项说什么？D说，前提是，除了sulfites之外，没有别的东西能导致过敏。其实D讨论了一个out of scope的问题！人家在讨论如何避免对sulfites过敏，你却去讨论有可能有别的非sulfites的过敏，当然是错的了！
