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.

正确答案为：B

这题目没大明白，请解释一下，说说是怎么推导出来的？

作者的观点是credit-card logo会提醒customer想到自己经济情况。他已经说了一个方面，就是当自己还挺"富裕”的时候，他们会多给tips。为了支持作者的观点，只用说出另一种情况，customer的表现就行了。（就是发现自己不够钱的时候就少给了）

这题是通过论述一个事情的两个方面来加强结论的

题干说的是   心理学家分析LOGO会影响消费者行为

因为在经济状况好的情况下, 消费者看到LOGO, 会多付钱(A=>B)

如果要加强的话, 可以反之, 经济条件不好的情况下, 消费者看到LOGO, 会少付钱(-A=>-B)
