没有思路GWD-2-Q9

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...很迷惑..请NN指教...题目中的首句话感觉和后面没有关系

原题说： 付现金的同学看到有信用卡标志的帐单盘时， 付的比较多。 解释是看到信用卡就觉得自己支付能力比较强。 暗示了这些付的多的同学都是有信用卡的。

问什么支持这个解释。首先我们看到这个解释在说什么， 基本上说信用卡的logo有暗示作用， 加强了消费者的消费信心。

B选项说， 那些欠了信用卡一屁股帐的同学们看到logo就会少付小费。

这个选项看起来跟那个解释不太一样， 但是付的多和付的少的例子都强化了信用卡logo对用户消费信心的影响。

明白了...原来是这样的加强..似乎和我原先思路完全不同
