标题: GMAT 逻辑分析题 (1)
Only a very small percentage of graduates from Peking University ever become board members of the 300 largest Chinese corporations. This shows that graduates from Peking University are underrepresented in the most important corporate boardrooms in China.

Which one of the following points out a flaw committed in the argument?

(A) Three hundred is too small a sample on which to base such a sweeping conclusion about Peking University graduates.

(B) It is irrelevant to smaller corporations whether the largest corporations in China would agree to have significant numbers of representatives from Peking University on the boards of the largest corporations.

(C) It is a mistake to take the 300 largest Chinese corporations to be typical of corporate boardrooms generally.

(D)The percentage of graduates from Peking University who serve on the boards of the 300 largest Chinese corporations reveals little about the percentage of the members of these boards who are from Peking University.

(E) The presence of graduates from Peking University on a corporate board does not necessarily imply that that corporation will be more financially successful than it has been in the past.

I choose D. 其实很明显，北京大学的毕业生很少进入TOP300的董事会并不能说明top300的董事会不是主要由北大毕业生组成。比如十年内北大毕业生有20000个（每年毕业2000人），只有1000个进入了TOP300董事会，5%的比例可以说是少的，但是这意味着平均每个公司的董事会由3个是来自北大的，董事会才几个人？北大比例就很高了。

D 对的呀

The correct answer is (D). kevin0214 gave a very convincing analysis.

Answer (C) It is a mistake to take the 300 largest Chinese corporations to be typical of corporate boardrooms generally.

The problem with answer (C) is that while the argument equates the 300 largest corporations with the "most important corporate boardrooms," answer choice (C) equates the 300 largest corporations with "typical corporate boardrooms". This is like comparing apples with oranges, which is never allowed in logic reasoning. There is a difference, no matter how subtle, between the "most important boardrooms" and "typical corporate boardrooms." Therefore, answer choice (C) is out.

Let's take a look at answer (D) The percentage of graduates from Peking University who serve on the boards of the 300 largest Chinese corporations reveals little about the percentage of the members of these boards who are from Peking University.

Interesting. If you read the stimulus carefully, you might realized that the flaw of the argument is -- while only a small percentage of graduates from Peking University eventuall make it to the corporate boardrooms (0.2%, 600 out of 30,0000), it's possible (although highly unlikely in reality) that everyone on a corporate board of 300 largest Chinese corporations (2 board member each, 600 total) could have been a graduate from Peking University. That would lead to the conclusion that Peking University graduates represent 100% of the most important corporate boardrooms in China. Clearly the argument picked the wrong percentage as evidence to support its conclusion

Answer choice (D) best reflects this error in reasoning.

How can you make up such a good question? You are cool~

Hihi~sdcar2010
Firstly, thanks so much for sharing such wonderful things.
To tell the truth,logic is alwarys the pain in my neck~

Hard is trying to figure out what the "key point"is in tackling the problems~here is a question from OG 12th( critical reasoning NO.107)

Last year all refuse collected by Shelbyville city services was incinerated. This incineration generated a large
quantity of residual ash. In order to reduce the amount of residual ash Shelbyville generates this year to half of
last year’s total, the city has revamped its collection program. This year city services will separate for recycling
enough refuse to reduce the number of truckloads of refuse to be incinerated to half of last year’s number.
Which of the following is required for the revamped collection program to achieve its aim?
(A) This year, no materials that city services could separate for recycling will be incinerated.
(B) Separating recyclable materials from materials to be incinerated will cost Shelbyville less than half what it
cost last year to dispose of the residual ash.
(C) Refuse collected by city services will contain a larger proportion of recyclable materials this year than it
did last year.
(D) The refuse incinerated this year will generate no more residual ash per truckload incinerated than did the
refuse incinerated last year.
(E) The total quantity of refuse collected by Shelbyville city services this year will be no greater than that
collected last year.

I chose A) here is my reason:the new collection program must make sure that recycling would not lay out new
ash, thereby no materials that city services could separate for recycling will be incinerated.

I understand why D) is right ,which seems more reasonable than A) but I still need more digging about A)

waiting for your explanation! thanks again~

A) is too strict for a necessary assumption. Focus on the main conclusion. Let's say if you do A), you would cut the amount of refuse to be incinerated to only 10% (90% recycled). Great. But is that NECESSARY to reach the goal of cutting it to 50%? No. If you let part of the collected recyclable trash to be burnt (let's say 20% among the 90% collected), you can still reach the cutting to 50% goal since you still saved 70% of the trash from burning. Thus, A) is not a necessary assumption.

吐槽一下，要是GMAT逻辑题用中文出，初中生都做的出来。LZ你要么教教我们你英语是怎么提高的，要么教教我们看不懂题的时候怎么选对

楼上正解！！

LS and LSS, both of you missed the point of taking GMAT. You have to demonstrate both a strong command of the English language and the faculty of logical reasoning to become an attractive candidate for MBA programs. Strong English communication skill is a NECESSARY condition for a successful MBA study. If your English level is to the point of now knowing what a GMAT CR question is talking about, you should postpone your quest on the MBA journey and improve your language fundamentals instead.

As to how to enhance your English skills, I have posted quite a few posts at the TOEFL forum if you care to know:

你太乐观了。。。用中文，一道题1分30秒，也不一定能选对。别忘了这是一个考试，不是有充裕的时间去给你思考的，要学会快速解题，快速逻辑转换，而恰恰这快速是最难做到的。

所以无关中文，英文。牛人看不懂题也能选对~

题目内容不错，就是会不会把语感读坏啊？
啥which的什么修饰问题都是SC里不允许的
楼主的题目出的也类似跟GMAT一样绕这点我比较喜欢
