有问题大家可以在此问啊，大家一起讨论。我尽量以最快的速度解答。我不是NN，但是逻辑还不错，呵呵，兑现我回馈CD的诺言。

----------------------------------------半年分割线-------------------------------------------------------------
之前为申学校，毕业论文，实习，各种诡异的事情忙着。以至于，一直荒废了CD，只回答了那些单独给我发邮件的同学的问题。现在一切都忙完啦，暑假刚好帮朋友复习GMAT，就顺便把逻辑贴重开了吧。只要上线就会回答问题，晚上可以在线讨论。不是NN，但是大家一起讨论应该思路会开阔很多哈哈。
杀鸡成功啦···
哈哈··

楼主，求教og94题
studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when thw bill is presented on a tray that bears a credit-card logo.consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available。

which of the following,if true,most strongly supports the psychologists' interpretation。
B.patrons who are under financial presure from their credit-card obligations tend to tip less when presented whit a restaurant bill on a tray with a credit-card logo than when the tray has no logo

E.the percentage of restaurant bills paid whit a given brand of credit card incresses when that credit card's logo is displayed on the tray whit which the bill is presented.

楼主，这道题不明白为什么选B，我选的E，现在看显然不对，但是B我也不明白，因为科学家论点是看到logo会多付钱，而B是有经济压力的人看到logo会少付钱，虽然是反向成立的，但是显然不符合题意啊？

对，这个E就是看着就能排除的，我看到percentage两个单词我就不想选。
题目表达的意思是顾客看到credit card 的logo会多给小费，因为credit card会提醒这些顾客，他们有多余的购买力。那很明显就是这个credit card 影响了顾客的决策
既然是这样的话，反向应该也是要成立的，credit card 有钱有购买力就能刺激顾客多给小费，credit card 没钱 under financial pressure就会提醒这个顾客他没钱没有购买力支付的小费也当然少，这样就加强了题干的结论了

谢谢楼主哈，再问下
科学家是这么推理的：
.consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more
表面意思上就是说看到logo就会多付钱，是不是完成题目还要求我们在自己推理一步，即把logo会影响付钱给推出来，而不是停留在题干表面的看到logo就会多付钱这个论点上呢？

106.(31188-!-item-!-188;#058&005724)(GWD 28-Q32)

A prominent investor who holds a large stake in the Burton Tool Company has recently claimed that the company is mismanaged. As evidence for this claim, the investor cited the company's failure to slow production in response to a recent rise in its inventory of finished products. It is doubtful whether an investor's sniping at management can ever be anything other than counterproductive, but in this case it is clearly not justified. It is true that an increased inventory of finished products often indicates that production is outstripping demand. In Burton's case it indicates no such thing, however: the increase in inventory is entirely attributable to products that have already been assigned to orders received from customers.

In the argument given, the two boldfaced portions play which of the following roles?

A. The first provides evidence to support the conclusion of the argument as a whole; the second states that conclusion.

B. The first states the conclusion of the argument as a whole; the second states an intermediate conclusion that is drawn in order to support that conclusion.

C. The first is the position that the argument as a whole opposes; the second provides evidence against the position being opposed.

D. The first states an intermediate conclusion that is drawn in order to support the conclusion of the argument as a whole; the second states the conclusion of the argument as a whole.

E. The first and the second both state intermediate conclusions that are drawn in order to support jointly the conclusion of the argument as a whole.

LZ。。。我想问这个intermediate conclusion是神马意思。。我貌似遇到好多次了。。。

一道很小白的问题
希望帮忙解答一下
pp
22. (28829-!-item-!-188;#058&003748)

In the late 1980s, the population of sea otters in the North Pacific began to decline. There are two plausible explanations for the decline: predation, possibly by killer whales, or disease. Of these two, disease is the more likely, since a concurrent sharp decline in populations of seals and sea lions is believed to have been caused by disease, and diseases that infect these creatures are likely to be able to infect sea otters also.

Which of the following, if true, most seriously weakens the reasoning?

(A) Killer whales in the North Pacific usually prey on seals and sea lions but will, when this food source is scarce, seek out other prey.
(B) There is no indication that the sea otter population at any North Pacific location declined in the 1980s because of substantial numbers of sea otters migrating to other locations.
(C) Along the Pacific coast of North America in the 1980s, sea otters were absent from many locations where they had been relatively common in former times.
(D) Following the decline in the population of the sea otters, there was an increase in the population of sea urchins, which are sea otters' main food source.
(E) The North Pacific populations of seals and sea lions cover a wider geographic area than does the population of sea otters.

这道题答案是A，E被排除的原因是无关选项？还是因为他会支持？

其实你说的也对，但是这里的logo影响付钱也不算往前推了一步，其实就是直接告诉你的嘛，顾客为什么多付钱？就是因为看到了logo啊··

不好意思，我刚回学校，回得有点晚
首先，我想说的是，我逻辑里面最不会的题就是BF题，所以你不要完全相信我回答。对IC，我的理解是根据前面的解释或者证据给出的一个中间结论，而这个中间结论的作用又是为了得出最后的结论而服务的。我这样理解去做题的时候基本能得出答案，所以应该还是挺实用的，你多做几道找找感觉。

逻辑贴重开，重新开始啦···
