65. According to advertisements, the higher a suntan lotion’s sun protection factor, or SPE, the more protection from sunburn. In order for a suntan lotion to work, however, one has to remember to put it on before going in the sun, put on an adequate amount to cover the skin, and reapply it as needed. Therefore, it really does not matter what SPE a suntan lotion has.

Which one of the following best identifies the error in reasoning made in the passage?

A.It is unreasonable to assume that the only purpose of a suntan lotion is to provide protection from sunburn.
B.Because some people get sunburned more easily than other, the fact that there are different SPEs cannot be ignored.
C.It cannot be concluded that the SPEs is not important just because there are requirements for the application of the suntan lotion.
D.It is unreasonable to assume that all suntan lotions required the same application procedures in order to work effectively.
E.There is no reason to assume that manufacturers are unaware that people sometimes forget to apply suntan lotion before going in the sun.

答案是C，我选的是B。文章最后一句话 does not matter what SPE a suntan lotion has. 不是指SPE的种类么？那这样的话为什么不涉及B的difference people呢？
另外C也不太明白……

105. A survey of alumni of the class of 1960 at Aurora University

yielded puzzling results. When asked to indicate their academic rank, half of the respondents reported that they were in the top quarter of the graduating class in 1960.

Which one of the following most helps account for apparent contradiction above?

A.A disproportionately large number of high ranking alumni responded to the survey.
B.Few, if any, respondents were mistaken about their class rank.
C.Not all the alumni who were actually in the top quarter responded to the survey.
D.Almost all of the alumni who graduated in 1960 responded to the survey.
E.Academic rank at Aurora University
was based on a number of considerations in addition to average grades.

答案是A，我选的是E。
首先A没读懂，大量的不成比例的排名在前的男校友？这是什么东东？跟文章有什么关系啊？
另外E为什么不对呢？我觉得就是因为除了成绩外还有其他考量因素，所以填写调查问卷的学生才可能自己根据不同标准都觉得自己是top 25%吧？

最后，请问现在实战时难度是费费的还是OG的呢？我感觉费费做得叫天天不应叫地地不灵，回头再做OG倒觉得好多了，倒不是技巧上的，而是OG没有那么多很长的复杂句，也没那么多生词（对于我来说……）。实战要是费费的难度就哭死了

盼详解！谢谢！！！！！

第一个我觉得因为题目问error in reasoning。。
b就没有指出原文的错误论证。。而是引入其他理由了。。
c说的是不能仅因为防晒霜的使用有要求就得出spe无意义这种结论。。我觉得更符合题目的要求。。

第二个文章的意思是发了个调查，结果一半回答的人都说排名是在前面25%的。。
a说的是不成比例的的高分学生回复了调查。。例如10个人回复了，都是前25%的学生。。所以满足题目的情况。
e。。我开始也选了e，后来我觉得e说A校学术排名是基于很多条件的，这个rank应该是学校的。。不是学生自己的。。也就是学生觉得自己好也不代表rank就是前25%。。

第一题：首先我觉得它说的这个东西跟防晒霜差不多吧。（我觉得最近老看到这种需要背景的东西，感觉很恶心
），SPE我马上想到SPF么，防晒指数。。。题目中说因为顾客可以涂抹很多而且可以重复涂抹，那么SPE的指数就不重要了。但是涂得多涂得频繁不能说有用啊。（我觉得这倒题目女生做理解会快一点。。比如我这个经常研究防晒霜的人。lol）。所以答案是C。不能因为它有涂抹的要求（经常涂，涂得多）就说SPE没用了。

第二题：调查出来高层的研究生有一半多。样本代表性问题。alumni是校友毕业生。那么自然比例高了
