我只是想讨论一下原文的逻辑链，说了一下自己的理解而已。谢谢解答，祝早日加精！ ...

原文的逻辑链可以有不止一条，但是跟选项有关的只有我说的那一条。
我也只是想纠正你的错误而已，别没的意思。

Which of the following most logically completes the argument?

The irradiation of food kills bacteria and thus retards spoilage. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking. However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______.
A  many of the proponents of irradiation are food distributors who gain from food's having a longer shelf life  
B  it is clear that killing bacteria that may be present on food is not the only effect that irradiation has  
C  cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods  
D  certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is  分析D选项
E  for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded  
并不是很懂正确答案E选项的意思

这种题教一个万用万灵的方法：
这种题只看最后有用的那句，如果那句出现代词了，从前文中找指代，没出现代词前面都不用看。GMAC前面balabala说一堆的唯一目的就是把你整晕，让你的记忆负担增加，说白了就是让你晕菜。
This fact is misleading, since _______.
就这一句就够了。
This fact指代一定是一个fact，什么是fact？一定是For example这句，claim都不能是fact。fact就是“irradiation destroys B1”这件事吧？
你这么想：
结论是This fact (irradiation destroys B1) is misleading
前提是让你在选项里找。
你就在选项里找一个会造成misleading的情况就好了：
正确选项是不是必须说irradiation destroy B1这件事怎么怎么了？才可能造成misleading。
举例：
日本人都是色情狂这件事is misleading，当然我知道这是一个否命题。我如果要支持这句话是不是一定要围绕着“日本人是不是色情狂”来说？也就是“日本人”和“色情狂”必须同时出现在支持中？
不信我们试试：
日本人都是小短腿（没有”色情狂“）－无法支持
美国人都是色情狂（没有”日本人“）－无法支持
中国人都是正人君子（既没有”日本人“，也没有”色情狂“）－无法支持
日本人拍的那些色情题材的电影都是演戏而已，并没有发生在日常生活中（有”日本人“，也有”色情“）－支持
A. 没有B1
B. 没有B1
C. 没有B1
D. 都有，留下
E. 都有，留下
至此，DE无法区分，换招。

再回题干找“有效信息”：
发现“his fact is either beside the point, since much irradiated food is eaten raw, or else misleading”中出现eithor or，eithor or什么意思？不是就是。
一件事如果说eithor or是不是就等于“2分”了：是或者不是。
那我们看eithor包括了什么情况，or一定就是剩下的情况了。
this fact is either beside the point, since much irradiated food is eaten raw
irradiated food 生吃了是一种情况，也就是说or中说的情况一定是“irradiated food不生吃”，翻译成人话就是“让人煮了呗”！
回看DE，此时无论如何都要读句子了，那就读吧：
D说有些cooking比irradiation更损害B1
E说对于那些irradiated了也cooked了的食物，B1的损坏究竟是哪个处理说不清了。
注意D没说这些食物是不是煮了，只比较了煮与radiation哪个更损害B1
E说的是对于“既radiated又cooked的食物”。。。。
所以，E是正确选项。

至此，此题做完。是不是一直到做完题，我都没讲逻辑关系？
这就是这个方法的优点：即使你考场上晕菜了，大脑空白了，不能思考逻辑关系了，题依旧可以做对。找选项里有没有radiation和B1不难吧？最后就只剩两个选项了。找哪个cook了，哪个没cook容易吧？不用逻辑上理解，读下句子就知道。

谢谢啦！！！！！！  不过我还想问一下  这里THE FACT代指的内容会不会是前面的所有句子和观点，因为我并不能直接确定它代指的就是for example的内容，前面的句子也是事实啊。还有就是最后的either or的句子也并没有作出结论，只是说把二者比较的做法是不对的。

谢谢啦！！！！！！

你看看你自己都承认是被前面的balabala绕晕菜了吧？前面的逻辑关系一定会很复杂的，不复杂能绕晕你？你不看前面一堆屁一样解题。
这个方法我说你用你肯定不敢直接用，你把OG，prep上这样的题找出来，自己试一下不就知道能不能放心大胆的用了？

这题里就一个fact就是For example句。你要看句子和句子之间的关系啊！第一句话是一个claim，however之后说一个跟第一句相反的claim，for example句支持however中的claim，points out是肯定是基于For example句的，因为points out句中有in this respect, this respect指代前句中的这个fact，所以是基于这个fact的further development，一定不是fact，而是claim。所以，fact一定是example句。

我...........还是好好去看看书  觉得这会是一个好方法的
多谢！！！！！！！！！！！！！！！！

昨天回去看看了og里面的题目，我发现有的题目还是不会运用您说的那个方法，可以再给我演示一道题吗？

Which of the following best completes the passage below?

At a recent conference on environmental threats to the North Sea, most participating countries favored uniform controls on the quality of effluents, whether or not specific environmental damage could be attributed to a particular source of effluent. What must, of course, be shown, in order to avoid excessively restrictive controls, is that .

• Aany uniform controls that are adopted are likely to be implemented without delay  分析A选项
• Bany substance to be made subject to controls can actually cause environmental damage  分析B选项
• Cthe countries favoring uniform controls are those generating the largest quantities of effluents  分析C选项
• Dall of any given pollutant that is to be controlled actually reaches the North Sea at present  分析D选项
• Eenvironmental damage already inflicted on the North Sea is reversible  分析E选项

首先，这题就是一个简单直接的方案推理，你按照方案推理做就好了。前面就一句话还是介绍背景的。。。不能更简单了。。。。
目标：avoid excessive restrictive control
就在选项里找哪个可以避免过度控制呗
A-说的是control什么时候执行，死
B-被控制的东西必须可以造成污染，留下
C-无关
D-被控制的污染物必须到达北海地区，留下
E-环境伤害是否可逆转，无关。
剩下BD比较：
B说的是可不可以造成污染，D说的是能不能到达北海
注意D中“到达北海”和“造成污染”之间还是一个gap：达到不一定造成污染
所以B是正确答案。
这其实就是一道assumption题啊

嗯嗯  这题我是做对了  就是以为会有更好的思路。谢谢啦！
