Question 11:

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.

答案是D，但我觉得答案应该是E。

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.

E说酒内的S自然含量不会高到让一些人产生过敏反应。言下之意，就是说，有一部分人身体较强壮，这自然酒的S含量挡不住他们；但并没有说明所有人都不会过敏。

D则说了没有会引起过敏的物质，除了S，则说明了所有人都不会有事。取非，如果除了S还有其他可以引起过敏物质的话，那么，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. 就不能成立了。

但D未说明加S前的酒中是否含有过量的S，这使得其有一个漏洞。从原文首句也看不出S是不是只是被人为加进去的。。。

可E如果把someone改成those，就好了。。。。

最后，我很无奈，还是选D。。。

我这里的逻辑推导有误吗？

晕，

我在楼上说的：

D则说了没有会引起过敏的物质，除了S，则说明了所有人都不会有事。取非，如果除了S还有其他可以引起过敏物质的话，那么，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. 就不能成立了。

仔细看了看发现D是无关选项，因为“取非，如果除了S还有其他可以引起过敏物质的话，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. ”依然成立，这句话只针对S的过敏来说的。

那么E依然有一个someone的问题呢。。。。。。。。。

The asnwer is E. I remember that first time this question was asked I chose D wrongfully.

D brings up allergan other than sulfites. But the question is about people allergic to sulfite. The conclusion is that these people would not suffer allergy to "sulfites". Therefore, D is irrelevant unless the conclusion is that these people would not have allergy at all.

NN啊！

自我分析：

结论：会对S物质过敏的人，可以喝没有添加S物质的酒，避免对S过敏；

A，复制防腐剂的效果，无关；

B，不是所有S会引起过敏，无关；

C，S的添加对象，无关；

D，除了S外，酒里没其他物质会引起过敏；

超级迷惑选项，我就选了这个！

注意题目结论里限定的很清楚：without risking an allergic reaction to sulfites.

结尾单词不是说的
        without risking an allergic reaction to these wines
            

题目结论限定了是：不会因此对S过敏了；对S的反应才是讨论的范围；

而不是说：不会因为喝酒而过敏；

对D取非的话：如果除了S外，酒里还有其他引起过敏的物质；

结论就是：那这些人还是会对这些wine过敏；

削弱的只能是：without risking an allergic reaction to these wines
            

而不能削弱：without risking an allergic reaction to sulfites.

因此D是无关选项！讨论对象错误！

E，那些酒里不会自然带有S物质；
