※ 引述《lovekyoko (匹茲堡的天空)》之銘言： : 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. 支持題，注意結論句在討論什麼。結論句的因果關係大致是: spending power exceeds the cash---willing to spend more 也就是討論到底是不是因為信用卡logo會讓人覺得有較強的支出能力而願意付多一點錢，主題 在討論到底會不會因為信用卡logo而想spend more。 答案B是無因無果類型，去除spending power這個因，就不會導致willing to spend more 這個果。AT無因無果類型題目不少，可以去找SV40那題，也是相同概念。 至於答案E，已經跳脫議題焦點，答案E是在討論用信用卡logo是否會讓"使用信用卡"的 量增加，和是否想spend more無關。 : Which of the following, if true, most strongly supports the psychologists’ : interpretation of the studies? : (A)The effect noted in the studies is not limited to patrons who have credit : cards. : (B)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. : (C)In virtually all of the cases in the studies, the patrons who paid bills in : cash did not possess credit cards. : (D)In general, restaurant patrons who pay their bills in cash leave larger tips : than do those who pay by credit card. : (E)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 : 請問B是哪裡有支持哩 感覺不出來 : 我是在b跟e做選擇 : 所以我選e : e又錯哪裡?? 感覺這題很繞 所以我迷路了 冏 --
