先来如约分享下OG CR题目
84 Many people suffer an allergic reaction to certain sulfi tes, including those that are commonly added to wine as
preservatives. However, since there are several winemakers who add sulfi tes to none of the wines they produce,
people who would like to drink wine but are allergic to sulfi tes can drink wines produced by these winemakers
without risking an allergic reaction to sulfi tes.
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 sulfi tes by
means that do not involve adding any potentially allergenic substances to their wine.
(B) Not all forms of sulfi te are equally likely to produce the allergic reaction.
(C) Wine is the only beverage to which sulfi tes are commonly added.
(D) Apart from sulfi tes, there are no substances commonly present in wine that give rise to an allergic reaction.
(E) Sulfi tes 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.
我想用这道题和大家探讨下，怎么确定out of scope,也就是那些选项是来打酱油的无关选项。
通读题干后，premise 1 many people对certain sulfi tes过敏，包括被夹在葡萄酒中用作防腐剂的certain sulfi tes，
premise 2 一些酒商的酒里面不加certain sulfi tes
结论：过敏的人可以喝不加certain sulfi tes酒商造的酒
问题是assumption
我读完以后，觉得最核心的概念就是几个字：certain sulfi tes，被酒商加入酒中，过敏
在选项中，A These winemakers have been able to
duplicate the preservative effect produced by adding sulfi tes by
means that do not involve adding any potentially allergenic substances to their wine.
读到黑体字部分开始有out of scope的感觉，因为这个东西对葡萄酒的防腐功能并非重点，重点是“过敏”，无关排除
B
Not all forms of sulfi te are equally likely to produce the allergic reaction.
黑体字对应的是题干中的certain,很明显又超出了讨论范围，无关
C Wine is
the only beverage to which sulfi tes are commonly added.
看到绝对化形容词要警惕，况且这完全和题目没啥关系，对葡萄酒中的ST是不是过敏，和葡萄酒是不是唯一被加入ST的饮料无关；
(D)
Apart from sulfi tes, there are no substances commonly present in wine that give rise to an allergic reaction.
看到这里，就可以考虑排除了，再次重申，本题讨论的是对不对ST过敏的问题，“without risking an allergic reaction to sulfi tes”题目中一直在强调，如果不放心，还可以继续看，看到no substances 可以肯定排除了，讨论的对象已经与题目无关
(E) Sulfi tes 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.
这个选项之所以正确，除了排除法，还有几个点很招人喜欢，are not naturally present迅速和题干中的重要 概念之一“被酒商加入”有所呼应，再看后面 large enough to produce an allergic reaction 又和句子的核心概念，
ST是否引起过敏对应，即使不能完全理解E选项的意思，此时也应该果断选择E了。
CR题，考察的是我们怎么在干扰信息中找到逻辑主线的能力，所以在做题时时刻保持头脑清醒，不被海量信息迷惑是最关键的一点，其实这也是未来工作中非常需要的素质之一。
