GWD3-Q9

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.


答案是B,后来我也觉得对。。。

想听听各位大虾对这道题目解题的看法,因为我着实花了很长的时间解决这个问题

我也纠结了好久问别人才懂的

A C D E其实都是无关选项

B看似也是无关,但是有一点和文中相通

文中说  because it reminds them that

这里意思是信用卡logo有remind的作用

B也正是提到了这个Remind,虽然是反方向的

A C D E都无关啦。

然后 B选项 其实是题目中Consumer psychologists的讲法的逆否命题,所以是对的,有加强作用。我是这么想的。大家怎么看?

1、不一定要充要,有支持就行
2、要是题干issue“桥墩”直接的关系
3、关系要与题干同向

Issue: logo=>(car-holder)feeling more powerful=>larger tips
         (car-holder)feeling 和 amount of tips正向相关

A 无关
B 说明 feeling 和 amount有关,且同向变化(psychologist的观点是:1 (assumption) feeling和amount有关 且2. feeling more powerful=.>larger tips 同向变化关系)
           B说的虽然是负向的情况,但也说明是两个桥墩“同向变化”的关系
C 无关 或者 削弱  无关—没说明feeling 和amount的关系
削弱—没卡,所以不是feeling惹的祸,断桥削弱(但有人说,没卡就不能feeling么?恩。。我也不确定,但是也没有说feeling和amount的关系,最多是个无关,也不是加强)
     D 无关 本项说的是payment way 和 amount的关系
     E  无关  percentage of ….. 无关
