求助 CR OG12 84

小哈

84. Many people suffer an allergic reaction to certain sulfites, includingthose that are commonly added to wine as preservatives. However, since thereare several winemakers who add sulfites to none of the wines they produce, people whowould like to drink wine but are allergic to sulfites can drink wines producedby these winemakers without risking an allergic reaction to sulfites.
Which of the following is an assumption on which the argument depends?
(A) These winemakershave been able to duplicate the preservative effect produced by adding sulfitesby means that do not involve adding any potentially allergenic substances totheir wine.
(B) Not all formsof sulfite are equally likely to produce the allergic reaction.
(C) Wine is theonly beverage to which sulfites are commonly added.
(D) Apart from sulfites,there are no substances commonly present in wine that give rise to an allergicreaction.
(E) Sulfites are not naturally present in thewines produced by these winemakers in amounts large enough to produce an allergicreaction in someone who drinks these wines.
求助大牛们，这题的意思是到底是对S那个东西过敏，还是对S非自然形态的添加剂过敏啊？？还是别的？有没有人能帮我翻译一下这题的题目和选项A，E啊？？每次复习逻辑到这个题都会卡住，请求赐教！先谢过了。

我也刚复习完这道题。我的思路是：
先找结论，即对S过敏的人可以放心的喝SEVERAL WINEMAKER 的酒。
A说这些WINEMAKER通过添加不含任何过敏性物质的防腐剂，替代了S的作用。看似的确服务于结论，可以先留着。
B、C、D明显不服务与结论，排除。
E是说S除了防腐剂，还可能存在NATURAL的酒中。但是酒中S的含量不足以导致过敏。这属于排除他因。必然对。

最后，以防万一用lawyer的test也就是对AE去非。A去非后是说WINEMAKER不能找到代替S的防腐剂，这对原文毫无影响。防腐剂不填就不填呗，又没说不填一定坏。
E去非，明显否定结论，也就是不能放心喝因为NATURAL的酒本身也非常危险。
非牛，菜鸟一只，共勉吧。
