Q9:
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?
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.
Q15:
Capuchin monkeys often rub their bodies with a certain type of millipede. Laboratory tests show that secretions from the bodies of these millipedes are rich in two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate capuchins. Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes.
Which of the following, if true, provides the most support for the scientists’ hypothesis?
Answer:

Q38:
Journalist: Well-known businessman Arnold Bergeron has long been popular in the state, and he has often talked about running for governor, but he has never run. However, we have just learned that Bergeron has fulfilled the financial disclosure requirement for candidacy by submitting a detailed list of his current financial holdings to the election commission. So, it is very likely that Bergeron will be a candidate for governor this year.
The answer to which of the following questions would be most useful in evaluating the journalist’s argument?
Q41:
Magazine Publisher: Our magazine does not have a liberal bias. It is true that when a book review we had commissioned last year turned out to express distinctly conservative views, we did not publish it until we had also obtained a second review that took a strongly liberal position. Clearly, however, our actions demonstrate not a bias in favor of liberal views but rather a commitment to a balanced presentation of diverse opinions.
Determining which of the following would be most useful in evaluating the cogency of the magazine publisher’s response?
Q22: Denoma, a major consumer-electronics maker, had a sizeable decline in sales revenue for its most recent fiscal year. This result appears surprising, because electronics retailers report that although their overall sales were considerably lower than in the previous year, their sales revenue from Denoma models actually grew, largely thanks to some innovative and popular models that Denoma introduced.
Which of the following, if true, does most to explain the apparently surprising result?
Answer:
It's better if you could break down this to several posts.

Sorry已更新
难怪我逻辑老是不好
倍感开心，GWD-41终于读懂了，解释一下：
C 是说：要是第一次的review显示的是liberal position ,那the magazine还会不会做进一步的reviews呢？

欧已经迷惑了，nanalin 说 Q38 选 B, 在看其第2个链接n多人选 E.
有没有定论？

GWD7-38 有没有定论？
to joe11，除非官方给答案，否则如何有定论呢，周围取决于你觉得谁有道理。
我认为B明显错误。它虽然肯定回答能加强原文结论，但否定回答对原文结论不起削弱作用。对B否定，即还有其他方法可以完成选举委员会要求的financial disclosure ，这不能削弱B的完成financial disclosure requirement 表示它要竟选governor。就像表示竟选governor有三种做法，某人按一种做法去表示他要竞选governor，你不能说有其他做法的存在便说他的做法不算，不能表示他要竟选governor。俗话说井水不犯河水嘛。
E是用某个人过去的做法来评价现在的做法。当然起评价作用
GWD-12verbal里的22题
Key: E
"命题成立不代表其逆否命题成立"
什么时候又有这种解释了?
我认为B明显错误。它虽然肯定回答能加强原文结论，但否定回答对原文结论不起削弱作用。对B否定，即还有其他方法可以完成选举委员会要求的financial disclosure ，这不能削弱B的完成financial disclosure requirement 表示它要竟选governor。就像表示竟选governor有三种做法，某人按一种做法去表示他要竞选governor，你不能说有其他做法的存在便说他的做法不算，不能表示他要竟选governor。俗话说井水不犯河水嘛。
E是用某个人过去的做法来评价现在的做法。当然起评价作用
对这个问题，偶对lawyer大牛稍微作点“削弱”。
对B的肯定回答，其加强作用没有争议。但否定回答， 当然也能削弱了，因为文章说，递交材料是竞选的only way ，不交材料当然不能参选，这是个必要条件，而且偶觉得削弱的口气甚至大于加强（可以理解为一种必要条件的假设）。而且为了使题目更无懈可击，提问也用了一词： likely 。偶理解，只要能做到大部分的加强或削弱就可以了。
希望NN们指正，最好能说动lawyer大牛亲自出马
偶觉得E还是无关,因为这是以前的年份,不一定对今年的起作用,比如原先要求当省长,必须要先当过市长,而今年要求当省长的必须是"海归",这种变数太多,很难说是能起到加强或削弱作用.但现在偶有一种感觉,好象GMAT喜欢用这种不同年份或不同公司,或是不同人的情况作点对比类的加强或削弱.
支持B选项， E真的很难理解。Bergeron had fulfilled the financial disclosure requirements for candidacy before any previous gubernatorial election 但是he had never run ,没办法联系在一起阿

支持zhaoyak7, CHOOSE B:
xxxx 不是 参选的唯一办法。。。。。 那么就削弱了记者根据xxxx 就判断要参选的推理了。。。。。
