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 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 given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is prepared.

没看明白题目,请NN们给讲讲B是怎么support的,谢谢.

我选C,

题的意思是说,用信用卡的人比付现金的人要慷慨一些,因为使用信用卡让他们觉得他们的支付能力大于他们所有的现金.

那么C就支持了这一说法,是说用现金付账的人都没有信用卡,这是把两个人群进一步的做了严格区分,使命题更严密了.

明显是B

文章说看到信用卡的LOGO会使人多付钱

这是文章的结论，要支持就支持这个结论，B说在经济压力下的人看到这个LOGO会少付钱,说明这个LOGO是对付款多少起作用的

另外，题目的意思是不是说用信用卡付款和用现金, 是说帐单上有信用卡LOGO,使人多付TIPS,
