94. Studies in restaurants show thatthe tips left by customers who pay their bill in cash tend to be larger whenthe bill is presented on a tray that bears a credit card logo. Consumerpsychologists hypothesize that simply seeing a credit-card logo makes many credit card holderswilling to spend more because it reminds them that their spending power exceedsthe cash they have immediately available.
Which of the following, if true, moststrongly supports the psychologists’ interpretation of the studies?
(A) The effect noted in the studies isnot limited topatrons who have credit cards.
(B) Patrons who are under financial pressure from their credit-card obligationstend to tip less when presented with a restaurant bill on a tray with a credit-cardlogo than when the tray has no logo. B
(C) In virtually all of the cases inthe 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 largertips than do those who pay by credit card.
(E) The percentage of restaurant billspaid 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.
E为啥不能支持呢》我觉得E也是加强的啊

E的意思是，选择用信用卡这种付账方式的比例增加，原文需要加强的结论是，看到logo,愿意花更多的钱（即给更多小费）

我觉得E可以理解为：既然原文要加强的结论是人们看到logo以后想到自己还有信用卡，所以觉得很有钱愿意花更多的钱；
那既然这样子的话，看到自己牌子的信用卡的话就更加会激发让他留更多小费的激励了。。。
讨论下哈，我总觉得E也可以，呵呵

可是，按照e看到自己牌子的信用卡，所以选择用信用卡付账的人多了，并不代表他们会多付小费。。。
