Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the 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 of the studies?
(A) The effect noted in the studies is not limited to patrons who have credit cards.
(B) Patrons who are under financial pressure from their credit-card obligations tend to tip less when presented with a restaurant bill on a tray with a credit-card logo than when the tray has no logo.
(C) In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.
(D) In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.
(E) The percentage of restaurant bills paid with a given brand of credit card increases when that credit card's logo is displayed on the tray with which the bill is presented.

请问为何选B？ B选项感觉沒有 "SUPPORT"...

就是说为什么那些人会消费多，是因为盘子上的logo提醒了他们，“你们有信用卡，有很多钱，所以就多给一点吧”

可是如果这个人天天被信用卡公司追着要债，那么他看到盘子上的logo时，就会提醒他“你没钱啊，还欠着那么多呢，少给一点吧~~”

不好意思 新手再请问一下...

“你没钱啊，还欠着那么多呢，少给一点吧~~” 算support“你们有信用卡，有很多钱，所以就多给一点吧”的论点 ？？

因为既然有负债,都没钱了 又要怎麽支持论点可以多付Tip的推论呢？

如果 欠信用卡公司钱+看见logo 这两件事情可以让你少掏小费。说明了是存在心理作用的啊。

因此 就有可能是  有信用卡+看见logo 可以让你多掏消费。

原文中第一种情况只是说有信用卡，没说欠钱啊。第二种情况才是说under pressure 如何如何。

用XDF的方式来说，A代表原因，B代表结果。此题是典型的BA型。针对这种题当然可以用A否推出B否啊。所以正确选项就是把原文中的A到B进行了A否到B否的处理啊。记住套路就行了，在应付简单题时还是可以用到的，毕竟此题没什么陷阱。

文章是从反面支持的　(不怎么多)

打个比方：看到建行信用卡的logo就提醒我：我挺有钱的

怎么支持?

反面：（当我信用卡透支很严重时）看到建行信用卡logo，就提醒我： 我快破产了

支持了文章的思路：看到卡的logo确是可以提醒patrons,他卡里的资金情况

这个应该是要看支不支持心理学家的观点吧，

他们说信用卡logo能和消费者开销时的心理联系起来，题目里说的是，看到logo就觉得自己有钱，选项里说，如果自己财政危机看到logo就心慌，这样就证明了logo在花销时是起作用的···所以支持了心理学家的观点~

个人理解···

sky的总结又好笑又精辟~~
第二遍看这道题~
又加深了理解~
谢谢~~

这个题目的结构就是甲：A—>B，那么乙：非A—>非B，则是一种支持选项。这是一个旁证，是一个中间接支持，并不是题目成立的假设，是既非充分也非必要条件。

这种题型不是太多。
