Many people suffer an allergic reaction to certain sulfites, including those that are commonly added to wine as preservative. 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 teh preservatives 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 natually present in the wines produced by these wine makers in amounts large enough to produce an allegic reaction in someone who drinks these wines.

答案是E，但是我觉得选D，理由是它是建立在酒里面没有其他东西引起过敏反应。而答案E，跟他们生产的AMOUNT有什么关系呢？

请指教！

e) Sulfites are not natually present in the wines produced by these wine makers in amounts large enough to produce an allegic reaction in someone who drinks these wines.

E答案究竟是什么意思呀？好像读不明白！请求帮助！

我也有点疑问，因为我看答案怎么是D啊，但是我却选了E

说说我的想法吧：E的意思好像是在这些厂商生产的酒中，不会自然产生足够多S这个东西以至于引起某些人过敏。这个选项如果去掉not看，就变成了即便厂商不添加S，这东西也会自发生成导致人们过敏。于是S不会自发形成就是人们可以喝这些厂商的酒的必要条件了。

至于D，我觉得和A有相似之处，大概都是说除了S不会有别的东西导致过敏。但是文中指的是那些专门对S过敏的人，可以喝不含S的酒。我觉得他们并不对除了S之外的东西过敏，所以即便有其他东西可能是致敏物，但是这些人并不会受影响。所以这两个应该是无关选项吧。

我是这么理解的，哪位大牛指导一下吧！

 I prefer E.

The conclusion is:

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.

凡是涉及到除了sulfites以外的其他过敏刺激物的都是无关选项。

题目中there are several wine makers who add sulfites to none of the wines they produce是什么意思？

是说把sulfites加到没有含sulfites的酒中去吗？如若是这样，酒中不是又含有sulfites了吗，人不是又要过敏了吗？

不是很明白，清指教！

D说的是allergic reaction, 题目讨论的是allergic reaction to sulfites，D是无

关选项，选E。

 E选项排除了除了制酒商不添加含有sulfites的preservative外，其他产生

sulfites达到使人过敏程度的可能性，所以这个是正确答案。

本题argument的主体是“people who would like to drink wine but are allergic

to sulfites”，D选项是sulfites以外的过敏物质，所以与本argument无关。
