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.


The psychologists’ hypothesis is that the credit-card logos on the trays bring to the minds of
those who tip more the fact that they have more purchasing power than merely the cash
that they have at hand. Th is explanation would not be valid even if those people who are
not reminded of their own excess purchasing power—if in fact they have any such
power—when they see such a logo nonetheless tip more in such trays. Th us, if restaurant
patrons who are under fi nancial pressure from their credit-card obligations do not tip
more when their bills are presented on trays bearing credit-card logos, then the
psychologists’ interpretation of the studies is supported.

1.观察到的现象：当顾客的账单上有一个logo表明可以刷信用卡付账时，顾客会多给小费
2.心理学家假设：顾客看到logo已经会多付钱是因为这个logo使得顾客觉得他们的消费能力比他们现在手头上的钱多（因为可以刷信用卡）
3.结论条件：顾客感到他们的消费能力比手头上的钱多就会多给小费

C选项指出，当消费者有还贷压力（信用卡的钱通常是月末还的），他们便会少给消费。
有还贷压力其实就是说消费者认为他们的消费能力并没有手头上的钱多（手头上的钱还得去还信用卡），所以他们会少给小费。
这就是支持的题干中的假设。
