对一个选项的误解，求指教

Sulfites are not naturally present in the wines produced by these winemakers in amounts large enough to produce an allergic reaction in someone who drinks these wines.

这是一个逻辑题的选项，这个否定not,答案的意思是are not large enough,可是如果是not naturally present就是完全不同的意思了啊，这句话该怎么理解啊？

语言的写作是为了让读者简单扼要的明白句子的意思，这里的not 不会跑过半个地球去否定后面的, 这里就是否定naturally present 的

但是，按照答案的理解，：”这个东西在wine里自然存在的量不足以大到让喝的人产生过敏反应“，这个意思才是对的，
这里贴上这道逻辑的题目，
Many people suffer an allergic reaction to certain sulfites, including those that are commonly added to wine as preservatives. However, since there are several winemakers 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 winemakers without risking an allergic reaction to sulfites.
Which of the following is an assumption on which the argument depends?
A These winemakers 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 reaction.

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 winemakers in amounts large enough to produce an allergic reaction in someone who drinks these wines.

答案是E
