13．POINT AT ISSUE
看原文：找出说话的人的结论和前提，特别是结论，多数不同的是观点，少数是前提。
找答案：用其中一个结论作为有关无关排除必错选项，再用另一个结论找出最综答案。对于说话人的结论是MORA或ETHICAL，则关于FACTUAL SITUATION的答案必错，反之亦然。结合TEST
TEST：AGREE/DISAGREE。其中一个人说“I AGREE，THE STATEMENT IS CORRECT”，另一个人必说“I DISAGREE，THE STATEMENT IS INCORRECT”。


我想了半天，不懂  “  对于说话人的结论是MORA或ETHICAL，则关于FACTUAL SITUATION的答案必错 ”  这句话的含义。 发现毛毛的OG题目分类中  将 MAIN POINT 和FILL IN THE BLANK 划为这类题型。



34. Which of the following most logically completes the argument?
Ferber’s syndrome, a viral disease that frequently affects cattle, is transmitted to these animals through infected feed. Even though chickens commercially raised for meat are often fed the type of feed identified as the source of infection in cattle, Ferber’s
syndrome is only rarely observed in chickens. This fact, however, does not indicate that most chickens are immune to the virus that causes Ferber’s syndrome, since .
(A) chickens and cattle are not the only kinds of farm animal that are typically fed the type of feed liable to be contaminated with the virus that causes Ferber’s syndrome
(B) Ferber’s syndrome has been found in animals that have not been fed the type of feed liable to be contaminated with the virus that can cause the disease
(C) resistance to some infectious organisms such as the virus that causes Ferber’s syndrome can be acquired by exposure to a closely related infectious organism
(D) chickens and cattle take more than a year to show symptoms of Ferber’s syndrome, and chickens commercially raised for meat, unlike cattle, are generally brought to market during the first year of life
(E) the type of feed liable to be infected with the virus that causes Ferber’s syndrome generally constitutes a larger proportion of the diet of commercially raised chickens than of commercially raised cattle
 呜呜，，以这题为例，，求讲解！！！！！

觉得“说话人的结论是MORA或ETHICAL，则关于FACTUAL SITUATION的答案必错 ”这句话是用来引导排除有关无关选项的，即题中的结论如果是作者主观的推论、作者的说法，那么选项中陈述事实的选项就一定是无关选项，是必错的，直接排除；反之，如果结论是事实的，那么选项中带有主观意味的就是无关选项，直接排除。但这个排除的方法貌似并不适用全部，也可能是我用的不好。
