OG12 CR94
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.[c1]

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) [c3]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 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[c4] did not possess credit cards.

(D) [c5]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[c6] on the tray with which the bill is presented.

这道题我刚开始也很迷糊， 前提：当看到信用卡logo的时候会支付更多的tips，心理学家的假设：是因为信用卡的logo提醒持卡人他们可以花超出他们现有的现金，因此会支付更多。要找出support这个假设的选项。B选项是当信用卡持卡人有财务困扰的时候，在餐厅看到logo会比没看到logo之前支付更少。取非就可以了， 某种现象——假设，如果B不成立，A也不成立，如果B成立，A也成立，是support的选项。D选项，这里是不管有没有信用卡，都是用现金支付的。
