有人能帮忙翻译一下这道GWD逻辑题吗？

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 能帮我解释一下吗？

这道题谈那些人看到CC的logo会对他们产生很大的影响. 这个被心理学家提出的理论是基于这样一个关键点--人们是否看到logo.  也就是说看见与否对消费行为有很大影响.

而B说,那些被债务压迫的穷苦大众中,看见logo的会比那些没看见的付更少的小费,也就证明了心理学家的观点,即logo对消费行为影响很大.

个人观点,有错误还请NN及时指正

消费者看到logo 多付小费

说是因为logo出现让消费者觉得他们的购买力是超出其现有的现金能力的。

B：有经济危及的人，看到logo，提醒他们，他们的购买力是小于其现有现金能力的，所以消费付的少

支持结论：信用卡logo对消费能力有影响力

arg是正面的

B是负面的
