GWD3-Q9：

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?

Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?

1. The effect noted in the studies is not limited to patrons who have credit cards.
2. 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 credit-card logo than when the tray has no logo.
3. In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.
4. In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.
5. The percentage of restaurant bills paid with given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is prepared.

谁能告诉我思路到底是怎么样的呢？我完全没头绪，选了D。

我觉得应该是B。

假设这个LOGO对顾客的心理根本没有影响，那心理学家的观点就是完全站不住脚的了。

而B说信用卡还款吃紧的顾客，在看到有信用卡的LOGO时付的小费反而比不看到LOGO时少，这说明看到这个信用卡的LOGO对顾客的心理确实是有影响的（因为一看到LOGO联想到自己信用卡上欠了一屁股债还不出，所以尽量少付点钱），所以B在一定程度上可以加强心理学家的观点（虽然那个观点是另外一个方向的，但是起码B说明了LOGO确实对顾客心理有影响。仅此一点就可以加强心理学家的观点）。

其他几个选项基本都与主题无关。D应该不对，因为它比较的是付现金的顾客付的小费和用信用卡付款的顾客付的小费，题目里是顾客付现金时付的小费，所以D的比较没有意义。

为什么不是c呢？只有那些没有信用卡的人，才会去用现金。which prove the power.

C好像根本不着边际啊?心理学家的观点是,看到这个信用卡的LOGO使人觉得自己的实际消费能力比他们手上现金决定的消费能力大.但如果那些人没有信用卡,那他们的实际消费能力就是由手上的现金多少决定的了,根本不可能说看到信用卡的LOGO会觉得自己有更大的消费能力,因为他们没有信用卡可以透支.

        more because it reminds them that their spending power exceeds the cash they have immediately available.这句话不太懂？知道自己已经超支了，为什么还要SPEND MORE?请NN给指点一下？

这句话你理解错了吧.simply seeing a credit-card logo 意思是仅仅看见一个信用卡的商标, 这里没有说自己超支了啊?这意思是,仅仅看见一个信用卡的标志就会使有信用卡的人愿意花更多的钱,因为这个商标提醒他们,他们的消费能力实际上超过了他们手上的现金可能承受的能力.

看了philikittist的解释明白了：

题干中讲的是你有钱的时候，看到它会倾向多付小费；而正确选项B，从反面加强，说当你有经济压力的时候，看到它就会倾向少付小费。
