41. Raymond Burr played the role of lawyer Perry Mason on television. Burr’s death in 1993 prompted a prominent lawyer to say “Although not a lawyer, Mr. Burr strove for such authenticity that we feel as if we lost one of our own.” This comment from a prestigious attorney provides appalling evidence that, in the face of television, even some legal professionals are losing their ability to distinguish fiction from reality.

The reasoning in the argument is flawed because the argument

(A) takes the views of one lawyer to represent the views of all lawyers

(B) criticizes the lawyer rather than the lawyer’s statement

(C) presumes that the lawyer is qualified to evaluate the performance of an actor

(D) focuses on a famous actor’s portrayal of a lawyer rather than on the usual way in which lawyers are portrayed on television

(E) ignores the part of the lawyer’s remark that indicates an awareness of the difference between reality and fiction

答案是E，为何D不对？

70. A low-pressure weather system is approaching Plainville; rainfall results from about 70 percent of such systems in the Plainville area. Moreover, the current season, spring, is the time of year in which thundershowers, which sometimes result from low-pressure systems, are most likely to occur in Plainville.

Knowing which one of the following, in addition to the information above, would be most useful for determine the probability that Plainville will have a thundershower soon?

(A) the percentage of thundershowers in Plainville that occur in the spring

(B) the percentage of spring rainfalls in Plainville that are thundershowers

(C) the percentage of thundershowers in Plainville that result from low-pressure systems

(D) whether low-pressure systems in other areas are associated with rainfall

(E) whether Plainville has more or fewer thundershowers each spring than do near by towns

答案是B,为何不选C？

第一题我也不太明白什么意思；第二题说，70%的低压槽导致降雨，然后让你求雷雨的概率。那么B告诉你降雨中雷雨所占的比例，两个比例相乘，就可以了~但是我觉得这题目好像不是很严谨，因为文章只是说70%的低压槽导致降雨，但并不是说所有的降雨都是低压槽导致的，如果还有别的原因导致降雨，那么这个B也不对了~~~至于C，我觉得如果是C，首先，那个70%是无用信息了，但是也不准确，因为雷雨只不过很有可能是低压槽导致，也没说别的原因导致雷雨的可能~~~所有我觉得这道题目没正确答案~~~
话说狒狒逻辑都是LSAT的题目，我觉得有GMAT的思路还是有点不一样的~呵呵！我做了陈向东的那本书，里面LSAT的逻辑感觉明显和GMAT不太一样~~~

41.須注意此argument的line of reasoning,小心不要把author的意見和prominent lawyer的意見搞混了:
prominent lawyer: Although(讓步句,承認已知的事實)not a lawyer,Mr.B strove...as if(條件句,表示"好像",再次暗示已知的事實)...
此argument: prominent lawyer 無法分辨真實與虛假

題目問"此argument"那兒錯了?
D. 此argument專注於對actor的演技....(無關,此argument無提及)
E. 切中核心

楼上的，能不能吧41解释的详细点啊~还是看不懂~

第二题狒狒逻辑的解析是错的。这道题选B不选C的核心就在于是有时间限定的，要判断的是spring这个时间的雷雨概率。
问题里面有关键词soon，所以题目就变成了：
已知某地区在低气压下的降雨概率为70%，求在current season，spring时该地区在低气压下的雷雨概率。
如果是C，只知道在低气压下的雷雨概率。但你不知道spring有多大的雷雨概率。
而B就把spring加上了。低气压下的降雨概率70%*春天降雨条件下的雷雨概率=在春天，低气压下的雷雨概率
