94. 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 fi nancial 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.

正确答案是B，B提到了patron店主，和文中有何关系啊。还有正文的最后一句话it reminds them that their
spending power exceeds the cash they have immediately available.到底是有信用卡的人付小费少，是因为他们觉得自己的支付能力高？好像不是很通嘛。。。

谢谢！

B类似于非因非果

信用卡压力大→少付

取逆否 多付→信用卡压力小或支付力大  这个就和原文一样逻辑了

it reminds them that their spending power exceeds the cash they have immediately available
it指的是LOGO,信用卡的标志提醒他们:他们的支付能力是超过他们身上的现金量的 (暗示有信用卡的人付的小费多)

后来我想了一下，文中是要支持心理学家的思路：信用卡对付小费时有心理暗示，B也是支持这一论点的。。。
