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. 不好意思刚看到,你问的就是这句吧。意译一下:消费者在用现金结帐的时候,看到账单盘里有信用卡logo支付的小费就会多一些(指的是现金小费)。这里压根就没说用信用卡支付小费,半毛钱关系也木有。
再看选项:
(A) The effect noted in the studies is not limited to patrons who have credit cards. 排除了信用卡的影响,直接削弱了原命题逻辑链
(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 a credit-card logo than when the tray has no logo. 证明了逻辑链的相互刺激作用,support
(C) In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards. 都没有信用卡了——那还哪有logo对它的刺激呢?反正都没卡,就变一样的了。削弱。
(D) In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.没有提到logo的刺激,无关。
(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.只是比例,不涉及绝对值large与否,排除。
