52. Most employees in the computer industrymove from company to company, changing jobs several times in their careers.However, Summit Computers is known throughout the industry for retaining itsemployees. Summit credits its success in retaining employees to its informal,nonhierarchical work environment.Which of the following, if true, moststrongly supports Summit’s explanation of its success in retaining employees?(A) Some people employed in the computerindustry change jobs if they become bored with their current projects.(B) A hierarchical work environment hindersthe cooperative exchange of ideas that computer industry employees considernecessary for their work.(C) Many of Summit’s senior employees hadpreviously worked at only one other computer company.(D) In a nonhierarchical work environment,people avoid behavior that might threaten group harmony and thus avoiddiscussing with their colleagues any dissatisfaction they might have with theirjobs.(E) The cost of living near Summit isrelatively low compared to areas in which some other computer companies arelocated.

答案为B
从题目意思上我已经选了B了，
但是，从理论上来讨论这道题目的话，应该怎么考虑？

我的理解是：
B选项的意思不太好把握，是属于逆否命题，还是仅仅是否命题？

如下两个命题
人留下因为工作环境好

否命题
人离职因为工作环境不好

逆否命题
因为工作环境不好人离职

52：公司将retain员工归因于环境，如果真的是这样，那么环境好，能留下员工，环境不好，则员工走，说明A能推出B,非A推出非B，则A是B的充要条件
95：专家将消费行为归因于信用卡对人的影响，如果真是这样，那么信用卡钱足够，多花；信用卡钱不够，少花，说明A能推出B,非A推出非B，则A是B的充要条件

因此，可以说明这种归因是成立的。

类似OG 95
95. 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?
(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 a 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 a given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is presented.

选B

题目中结论是
因为看到信用卡标记让人觉得的支付力超过他们的现金，因此他们给的更多

答案B是
财政有压力的人，看到信用卡标记后会给的更少

这里又是如何解释呢？多谢
