42. For next year, the Chef’s Union has requested a 10 percent salary increase for each of its members, whereas the Hotel Managers’ Union has requested only an 8 percent salary increase for each of its members. These facts demonstrate that the average dollar amount of the raises that the Chefs’ Union has requested for next year is greater than that of the raises requested by the Hotel Managers’ Union.

 

Which one of the following, if true, most strengthens the argument?

 

A.        The Chefs’ Union has many more members than does the Hotel Managers’ Union.

B.        The Chefs’ Union is a more powerful union than is the Hotel Managers’ Union and is therefore more likely to obtain the salary increases it requests

C.        The current salaries of the members of the Chefs’ Union are, on average, higher than the current salaries of the members of the Hotel Managers’ Union
                    

D.       The average dollar amount of the raises that the members of the Chefs’ Union received last ear was equal to the average dollar amount of the raises that the members of the Hotel Managers’ Union received

E.        The members of the Chefs’ Union received salary increases of 10 percent in each of the last two years, while the members of the Hotel Managers’ Union received salary increases of only 8 percent in each of the last two years

 

Percentage、基数和绝对值的关系

A.        无关

B.         This is out of scope . The topic in the passage has nothing to do with the power of the 2 associations. The topic is only concerned with data analysis.

C.         基数大
                    （Percentage 大，基数又大，绝对值肯定大了）

D.        无关

E.         无关

这个我在 C  D 之间挣扎了很久 最终选择了D  不过不明白D 为什么是无关？

Joseph: My encyclopedia says that the mathematician Pierre de Fermat died in 1665 without leaving behind any written proof for a theorem that he claimed nonetheless to have proved. Probably this alleged theorem simply cannot be proved, since---as the article points out---no one else has been able to prove it. Therefore it is likely that Fermat was either lying or else mistaken w. hen he made his claim.

Laura: Your encyclopedia is out of date. Recently someone has in fact proved Fermat’s theorem. And since the theorem is provable, your claim---that Fermat was lying or mistaken---clearly is wrong

50. Which one of the following most accurately describes a reasoning error in Laura’s argument?

 

A.        It purports to establish its conclusion by making a claim that, if true, would actually contradict that conclusion.

B.        It mistakenly assumes that the quality of a person’s character can legitimately be taken to guarantee the accuracy of the claims that person has made.

C.        It mistakes something that is necessary for its conclusion to follow for something that ensures that the conclusion follows.

D.       It uses the term “provable” without defining it.

E.        It fails to distinguish between a true claim that has mistakenly between believed to be false and a false claim that has mistakenly been believed to be true.

 

答案：C

思路：

Laura的论证过程：该理论已证明—>没有说谎，他的CLAIM对。理论对并不能表明是P证明的，这只是必要条件，不是充分条件。

我不明白C 和LAURA的论证有什么关系 我觉得LAURA没什么不对的~

请各位指教啊~ thanks!

42.这道题和LZ犯一样的错误，我是这样理解的：

题目说的是for next year

而D选项说的是last year，

与C选项的current比，last year 应该是属于无关了

50.J ：由于Pierre de Fermat的理论观点没有人证明是对的，所以，Pierre de Fermat 不是说谎就是他的理论错误。

   L:  最近有个证明了Pierre de Fermat的理论观点，所以J的结论是错误的。

L 说有人证明Pierre de Fermat的观点的是对的，但是不能说明这个人的证明的是Pierre de Fermat所想的。

 

也有可能，Pierre de Fermat真的是说谎，误打误撞给出了一套理论，
        却被后人给证实了。。

我不是NN，分享下我的理解

 

楼主在国内么。四点还在学习。。
