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.

乍看C好象也有点道理,这些人其实没有信用卡,这不就说明是信用卡的标志起了暗示的作用么

但是题义里心理学家说的是持卡人倾向于干嘛干嘛,所以C是无关选项,起不到支持的作用了

还是应该B
