标题: OG12逻辑 94 求助高人
94. 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 fi nancial 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.

lz 你哪里有疑问呀?不说出来,大家怎么给你讲呢? 这题选b。
原文说在给小费时,如果bill上有信用卡的标识,则顾客会多给小费,因为logo提醒他们他们的支付能力高于他们当时身上所带现金数量。b选项说,如果一个人,他当时有巨大的信用卡偿还压力,那么,logo会提醒他,他的支付能力低于身上所带现金(因为要换信用卡上的钱),所以小费就给的少了。所以加强了logo对给小费的多少有影响。也就加强了题干中的结论,因为总有人是没有偿还危机的,那么,他们就会多给小费。

我看og上说 A C D都是weaken  哪位nn能解释一下吗?

刚好也在搜这个题的解释就看到你的问题了,不是NN
但是我理解的OG的ACD削弱是这样的,
A 这个影响不限于有信用卡的客户-- 也就是说,信用卡这个关键信息对顾客付小费没什么影响了,因此就削弱了原文说的“有信用卡的顾客看到这个LOGO会多付钱”
C 说实际上所有付现金的顾客都没有信用卡 ---同上,也是把关键信息的作用直接忽略了,也就削弱原文了
D 说用现金付款的顾客比用信用卡付款的顾客给的小费多--这个很明显削弱了原文有信用卡会付更多的结论

题干:
Conclusion 当盘子里有信用卡logo的时候,现金付款的客户比信用卡付款的客户给的小费高(现金付款的客户看到logo会受刺激)
Premise 看到信用卡logo后,让credit card holders想付更多钱,因为这让他们意识到了自己比现金支付能力更强(看到这里很自然联想,既然能力比现金支付强了,那我自然就愿意多掏钱了——说明收到了logo刺激!)
一开始看这个premise和conclusion我特别诧异,结论说现金付款的人消费高,为啥拿了一个信用卡付款的例子来佐证?!并且还都愿意多掏钱?!
所以题眼并不在付钱一定更多了上面!!(我就是一开始把自己带入了这个点,混乱了)

继续思考——

那么,GMAC在这题的tricky正在于,premise是说,有信用卡的人看到logo也会受刺激——这么做的原因是消除了顾客本身到底有钱没钱对他们tips多少的影响、消除了他们到底是有卡有钱的影响。
只谈信用卡logo出现了就刺激人们掏钱多了这一个因素。

这一招很妙,仔细回味ing。

所以如果要support conclusion,就要证明  影响付tips的动作----看到logo与否   这两者的关联。

再看选项:
(A) The effect noted in the studies is not limited to patrons who  have credit cards. 排除了信用卡的影响,直接削弱了原命题逻辑链
(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. 证明了逻辑链的相互刺激作用,support
(C) In virtually all of the cases in the studies, the patrons who paid bills in cash  did not possess credit cards. 都没有信用卡了——那还哪有logo对它的刺激呢?反正都没卡,就变一样的了。削弱。
(D)  In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.没有提到logo的刺激,无关。
(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.只是比例,不涉及绝对值large与否,排除。

这个分析简直绝了 !!不过一开始做题真的很难想到这样的联系,只能通过多研究这道题来提醒自己的这种思维。

108 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 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.

果因推理
果= 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.
因= 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.
答案必须再解释结果,没有说结果那就给结果另外的解释
A:没有再解释果
B:解释了结果。多给小费是因为信用卡的关系。少给小费也是信用卡的关系。增强了因果关系属于CQ2,因果关系。
C:没有解释结果
D:没有解释结果
E:没有关系

非A推非B,加强·

抱歉又顶起了老帖子

这里非A推非B是加强了,但是我们不是说A推B=非B推非A吗?这里怎么原命题和否命题等价了呢? 欢迎指正

A-->B, 不能得出, 非A-->非B (因果关系除外)

这题的加强逻辑就是把原文认为有关系,再重复一遍有关系。
即,原文说logo和小费是有关系的,选项B又说一遍,logo和小费是有关系的。这样的方式来加强。

噢 明白了 这里不强调A推B非A非B,答案是重复了客户付小费多少与信用卡标志的关系。谢!

这道题目的难点是argument是什么意思。我开始看不明白。其实,有个前提是tips都是cash,credit card holder给tips也是给cash。这个argument是说:
Conclusion:有logo的情况下,客人给cash更多,比无logo的时候给cash多。注意这个比较是和无logo的情况下比较cash的多少。
Premis:有logo的情况下,客人觉得自己消费能力高于当自己没有credit card只有cash的时候的,自己更有钱了,所以愿意给更多cash tips。credit card logo让客人觉得自己更有消费能力。
B选项:有logo的情况下,有还款压力的人会比无logo的情况下人付更少cash。意思是logo让客人觉得自己没有消费能力,因为有还款压力。
