Many people suffer an allergic reaction to certain
sulfites, including those that are commonly added to wine as
preservatives. However, since there are
several wine makers 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 wine makers without risking an allergic reaction to sulfites.
Which of the following is an assumption on which the
argument depends?
A.
These wine makers 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 reactions.
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 wine makers in amounts large enough to produce an
allergic reaction in someone who drinks these wines.
A是无关选项。原文没有说“所有的wine都必须要添加防腐剂，否则就会很容易变质”。原文说的事情是 后来厂商不添加防腐剂了，那么人们就不会过敏了。 不是说厂商能不能够添加没有过敏物质的防腐剂的事情
E是假设啊，对E取非明显原文的结论就不成立了啊
including those that are commonly added to wine as preservatives~~~原文已经说明S是要加到酒里的~~所以E没有道理
我还是觉得D好点
