这道题目好像没有讨论过。偶觉得E比B好，请大家讨论。谢谢。

Q31:

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?

1. The effect noted in the studies is not limited to patrons who have credit cards.


2. 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.


3. In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.


4. In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.


5. 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.

I choose B.

Because B responds to the psychologists hypothesize that the exist of the logo can effect the patons' feeling of their paying ability.

E is unrelated. what if more paid by credit cards but the tips become less.

我觉得Ｅ也说明了ｌｏｇｏ对人行为的影响啊？？

1. 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.

ｌｏｇｏ出现，于是人们就用这个ｌｏｇｏ的信用卡付账了…………
