另外一道是assumption的题
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.

我想看清了这个结论ABCD都是无关的吧...B选项之前很多人问，这里顺带提下，文章说了不是所有的S物质，是certain的才会引起，所以B选项其实已经被文章assume了，若再往深一步分析，会不会加入酒里面的S物质就是不会引起人们过敏那种呢？不知道！文章的信息没给...其实说到这里都是想太多，B很明显就是无关的，对于假设题还不放心你就取非，削弱的肯定是正确选项...
