83.A (25338-!-item-!-188;#058&001294)

Many people suffer an allergic reaction to sulfites, including those that are commonly added to wine as preservatives. However, since there are several winemakers producing wine to which no sulfites are added, those who would like to drink wine but are allergic to sulfites can drink these wines without risking an allergic reaction to sulfites.

Which of the following, if true, most seriously weakens the argument?

A. Sulfites occur naturally in most wine.

B. The sulfites that can produce an allergic reaction are also commonly found in beverages other than wine.

C. Wines without added sulfites tend to be at least moderately expensive.

D. Apart from sulfites, there are other substances commonly present in wine that can trigger allergic reactions.

E. Wine without added sulfites sometimes becomes undrinkable even before the wine is sold to consumers.

选A, 是不是因为sulfites在大多数酒里会自然产生，所以不加防腐剂的酒也会让那些人过敏？因为它说Many people suffer an allergic reaction to sulfites, including those that are commonly added to wine as preservatives. 因此weaken~

D错的原因是不是out of scope??

Thx~

原文只说对S过敏，没提到其他过敏源，所以削弱的也只是对S过敏的结论~~你的想法是正确的，不要怀疑自己

因果模式推理题生产了不添s的红酒 → 对s过敏的人可以买这些红酒喝了
这类题要基于对原命题对象的讨论。
D：取非：无论有没有别的过敏原，不会影响现在对s过敏人购买红酒的行为，也就是原命题。
我当时错选了E。
现在的分析：E扩大了原命题的讨论范围。原命题只讨论sulfite这一种防腐剂影响下红酒的购买问题。——进一步想，不添加sulfite防腐剂的红酒，不代表不添加别的方式的防腐剂啊。
