GWD-8-Q14: GWD-2-11

    

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.

这是GWD第6套的第14题，答案是E,但我怎么看都觉得不对劲，请各位高手帮忙分析一下噢，谢拉！！

是说这个东西只要不是人工添加的就不会导致坏结果吧（Not large enough)，所以那些没有人工添加的就不会有危险，  个人之见，还需大牛来解答，顺祝明天杀G成功啊，回来多奉献机经啊

题目：不添加——》喝着安全

那是没有ruleout这个可能：如果不添加但是sulfites本身在酒里就存在了呢？

所以假设就是：Sulffites不是naturaly present在酒里（并且还到令人过敏的量）的~E～

题目说工人制造了不加导致过敏的sulfites的wine，所以对sulfites过敏的人就可以喝wine了。

假设是：天然sulfites存在在wine里面的的sulfites不足以导致过敏，意味着不加就不构成过敏。

楼主+U哦～等着你胜利带着JJ的好消息～～～

在数学机经区问gwd的cr，LZ好强大~

原文说wine添加了sulfites就会allergic reaction ，结论是为了使人们不allergic reaction ，排除他因，就是排除wine本身含有sulfites足够使人allergic reaction 大概是这样吧

naturally present,天然存在的意思
