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?

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.

答案是B, 能帮我解释一下这道题吗? 谢谢.

我看了gwd逻辑汇总, 但没有任何解释, 请大牛们过来看看.

我對這題的看法是這樣的:

題目的意思是:研究指出，當放帳單的盤子上有信用卡的圖樣時(比方說:VISA or Master Card的logo)，付現金的消費者會給比較多的小費。消費心理學家就試圖解釋這個現象，他們認為，當消費者(許多擁有信用卡的人)看到這個圖樣時，會覺得他們的花費能力遠遠超過他們手邊擁有的現金(因為用信用卡可以欠欠卡費囉，很多人都會亂刷)，所以這些人就會花多一些錢(也就是多給一些小費)，反正有萬能的信用卡啊!

我覺得這題有一個缺點就是它沒有說清楚是不是這些付現金的人都有信用卡，不過我們就假設他們都有吧。

答案B就說明了"用信用卡的現象"，當這些消費者在有信用卡債的壓力下，他們如果看到信用卡的圖樣就反而會比沒看到時少給一些小費(因為債務纏身嘛，應該要節約一點)，答案就說明了信用卡圖樣的功能，只是題目是從正面說起，答案從反面說起，所以可以支持那些學家的假設。

完全不理解，请大N们看看是不是我理解错了？

题目说，心理学家认为，看到信用卡的LOGO，让人感觉可以花的更多，因为他们的实际支付能力大于他们所有的现金。

然后B说，看到信用卡LOGO，让那些有还债压力的人给的小费更少了...

题目说看到LOGO给的小费多，B说看到LOGO给的小费少，明明是削弱啊？怎么会是 加强？偶第一个就把B排除了，结果发现没答案。
