美国大学生也做错的逻辑题

As an experienced labor organizer and the former head of one of the nation’s most powerful labor unions, Grayson is an excellent choice to chair the new council on business-labor relations.

Which of the following, if true, would most strengthen the conclusion above?

(A) The new council must have the support of the nation’s labor leaders if it is to succeed.

(B) During his years as a labor leader, Grayson established a record of good relations with business leaders.

(C) The chair of the new council must be a person who can communicate directly with the leaders of the nation’s largest labor unions.

(D) Most of the other members of the new council will be representatives of business management interests.

(E) An understanding of the needs and problems of labor is the only qualification necessary for the job of chairing the new council.

我给我一个美国朋友做， 他一口咬定答案是B，和我选的一样。

实际答案是E，感觉E 说得太绝对，用ONLY 这个词。

奇怪的题。

感觉B的话，说的是过去。过去和商业界头头关系好并不代表现在怎么样吧。？。。。

感觉D的确是有点绝对。但是想想，问题问的是，如果下面那个条件是对的，所以，下面给的每个选项都是一个假设条件，既然是假设条件，用only就只是表示：对于chairman，这个职位只是(only)需要理解劳动人民的需要和问题所在。这么一来，如果这个假设是正确的，Gra...应该是能够当选为chairman的，因为它有丰富的经验......

排砖吧。。。

我也觉得是B.

Anybody has found the explanation of the correct answer?

hard to tell:

B will be the answer if we havn't E for our choice.

E wants to say that understanding of the needs and problems of labor is a required condition to become a chair the new council on business-labor relations.  So his experience will give him a hand to compete such position.

B: G has a good record of relations with business leaders. It will be ok, but when comared with E which is much more clear stated, choice B still has its disadvantage.

Has a good record of good relations is not enough since record doesn't reflect the truth sometimes. If B says G has good relations with business leaders will be much more powerful to strangthen the conclusion.

Anyway, it is an answer which needs us to get via throughly comparsion.

B will stand if E doesn't exist.

It is a better explaination.

however, I thought if we haven't  E, I'll pick B it seems the next to the best choice. E much more frankly stated the requirements needed to meet.

正因为绝对才选E, support Wamdola

坚决排除其他所有因素，才确定这个人选一定没错

非常同意楼上的观点，only的存在恰恰排除了考虑business因素的必要性，但是如果E的后面部分改成for the job of labor organization(比如说），那就得选B了。

不过说实话，题目中business这个词的存在很容易让人误入歧途，尤其在时间紧迫的情况下。
