Many people suffer an allergic reaction to sulfites, including those that are commonly added to wine as preservatives. However, since there are several wine makers producing wine to which no sulfites are added, those who would like to drink but are allergic to sulfites can drink these wine without risking an allergic reaction to sulfites.
(A) Sulfites occur naturally in most wine.
(B) The sulfites that can produce can allergic reaction are also commonly found in beverages other than wine.
(c) Wine 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 customers.
answer: A
想不明白原因.我觉得D对.它因(other substances)导致结果(过敏),即使s东西没有加进去,但还是过敏.是其它物质不在考虑范围吗?

in the talk about sulfites, any other types of allergic reaction is out of consideration.
A weakens the conclution perfectly by eluciating that Sulfites is kind of a nuturally occured substance in most wine. So no matter the wine maker adds sulfites or not, the wine contains sulties all the same.

哈哈，这个是GWD6-14的原题，也是OG12-84的原题。我刚才就这个不明白的了。也是看了CD上的NN解释恍然大悟的。
题中最后一句话without risking an allergic reaction to sulfites，是问不会引起对S这个东西过敏的假设。
D选项说的是对所有东西过敏的。所以不对呀
