1,Studies in restaruants 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 following most strongly supports the psychologists' interpretation of the studies?
答案Patrons who are under financial pressure from their credit-card obligations tend to tip less when preested with a restaurant bill on a tray with credit-card logo than when the tray has no logo.

有点困，我来帮搂主回答一下好了，我就简单的说了，有些答案或者题目也都不直译了，就按照我理解的说好了：
1。答案中说，信用卡欠债的那些消费者，看见了信用卡的logo会比不看见tip的少，从消费心理学来讲，这说明看见logo对于消费者的消费心理有影响。因此，证明了原文——即，看见信用卡的logo的人会有心理暗示：他们的消费能力比口袋里的现金要高，因为可以刷卡。
2。题目问得是，那个是对批评的最有力的反驳，即，反驳原文第二段。第二段说，不值得去换landscape，因为每年节省的水费才20块钱，根本不够补偿换landscape设备的钱。然而，答案却说，除了节省水费以外，新的landscape还能节省fertilizer and herbicide的开支，因此，反驳了第二段。即为，每年的节省大于仅仅水费的20块钱
3。取非吧。对答案取非，如果过去3年中，B国电视装配工的生产力提高了，也就是平均装配每台电视的时间减少了，即便工人数量减少了，也不能说明出产的数量相应的减少，即得不到：“从v国进口电视数量增加。”一说
4。T公司上周收到了4个shipment，其中3个是building supply，另外一个不是，而上周五发出的全部为building supply，因此至少有一个不是上周五寄出的
