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
