标题: 请教GWD3-Q9 饭店小费

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?

The effect noted in the studies is not limited to patrons who have credit cards.
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.
In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.
In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.
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，我选了D。虽然觉得D怪怪的，但是不明白B为什么正确~~~~

原文是X导Y

答案B是说Y非导致了X非

逆否命题～

B就是直接按照原文的思路来支持的呀，文中说用现金支付比用卡支付时支付的多。B选项说，没有有卡的LOGO ON时比没有LOG ON 要支付得多呀，就是说用卡负的钱少。
