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

这T 做的时候选了B ！之后看大家的帖子讨论集中在ADE 上面！看到LAWYER 选E ， MINDFREE 开始看错了选了D ，看清楚后马上选了E ！

感觉这T 的迷惑性怎么这么大啊！无关选择也很难排除啊！我想了很长时间！感觉A ，D 无关是因为文章一直在说对S 的过敏，而AD 都说了对其他东西的过敏就错了！

B 呢 我仔细看才看出来他说的是FORMS ，其实也是无关吧！文章没有说S 有什么FORM 只类的！

所以选E了就是S 的量上的问题，因为无论如何都得加这个S ！不知道思路对不对，LAWYER 帮助看看吧！

但是MINDFREE 举了个例子，

Why D is correct? One simple example: There is no wolf in the woods. So it should be safe for kids to play there. Assumption: there is no other wild animals such as tiger or snake that pose dange to kid.

如果他说的这个对，那D 就不无关了啊！

你分析得很对，其实只要抓住结论，对WEAKEN SOPPORT ASSUMPTION可以排除很多无关项，很多时候就排除剩下一个。其实D也是同样的问题。因为结论是讲对S的过勉。而D说只说过勉，没具体说对S的过勉。

谢谢LAWYER 那MINDFREE 举的那个例子对吗？

lawyer_1

对于MINDFREE的例子的结论讲，MINDFREE是对的，因为该结论没有针对WOLF。如果结论改为KIDS CAN PALY THERE WITHOUT RISKING THE ATTACK OF WOLF，则该假设错。因为结论局限于WOLF。楼主的题也一样，因为结论局限于without risking an allergic reaction to sulfites。所以D说的其他物质就无关了。

THANX + REALLY！ REALLY ！

严厉支持XY JJ 题目标准化！！（方便所有人的查找）

格式以改，多多注意！

题目很清楚地写到“。。。。those that are commonly added to wine as preservatives.”

所以再讨论naturally presented问题是无意义的（选项E)，文章已经通过common added 告诉我们是后来添加的。同时as preservatives告诉我们sulfites是用来做防腐剂的。所以如果那些葡萄酒制造商不添加sulfites的话，他们必须有别的方法来防腐。

所以选A.

还是有些不明白选E, 因为提干中已指出不加S, 所以似乎不用在讨论S的多少"However, since there are several wine makers who add sulfites to none of the wines they produce"

而D恰好是一个排除它因的选项. 望赐教.

可能是因为制酒的原料里面就含有sufities，D肯定不对，你看最后一句是

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

也就是说它对别的过敏和题目没有关系

感觉应该选E。如果E的Assumption 不成立。Wine中有Sulfites，则直接推翻了题干的结论。
