93. Commentator: The theory of trade retaliation states that countries closed out of another country's markets should close some of their own markets to the other country in order to pressure the other country to reopen its markets. If every country acted according to this theory, no country would trade with any other.
The commentator's argument relies on which of the following assumptions?
(A) No country actually acts according to the theory of trade retalitation.
(B) No country should block any of its markets to foreign trade.
(C) Trade disputes should be settled by international tribunal.
(D) For any two countries, at least one has some market closed to the other.
(E) Countries close their markets to foreigners to protect domestic products.
答案是D.
依我个人看这一题很奇怪的没有正确答案，我全都神奇地排除了，求解啊求解。
og上是说，世界上每个国家都对其他的国家的某些市场有封锁，连环下来可以推出是D。可是这题是假设题啊。
94（很悲催的连在一起的两题）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 avaliable.
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 tho 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 tray with which the bill is presented.
答案是B.为什么为什么，百思不得其解啊/

(D) For any two countries, at least one has some market closed to the other.
(E) Countries close their markets to foreigners to protect domestic products.

Necessary assumption. Use negation.

If you negate D), you have "For any two countries, neither has any market closed to the other". If this is the case and according to the trigger presented in the passage, not a single country would close out its market to any other country. The conclusion just falls apart. D) is the correct answer.

第一题题目的问题是题目论点是基于选项中的哪一种假设
如果D属实，结合题目中得理论----如果贸易双方有一方采取贸易保护手段，另一方也应该采取保护措施向对方施加压力，迫使对方取消贸易保护手段，按照D的说法，任意两国的贸易中都至少一方实施了贸易保护，于是就造成了所有对方都在实施贸易保护，或者是先实施贸易保护的一方迫使另一方也加入到贸易保护的行列，于是贸易无法再进行下去，题目最后的论点就实现了。
A、B明显与题目露点冲突，C与题目无关，E只是对题中理论内容的再描述。

第二题对于题干中心理学家的假设我尚无法理解，所以这题我也搞不定，同求高人解答

94 题是说信用卡的logo对消费的影响。
研究发现，当消费者看到信用卡的logo时，所付的消费就会多一些。
心理学家认为这是因为消费者看到信用卡的logo时就会提醒他们他们所拥有的消费能力高于他们所带的现金数量。
如果这个假设成立，即小费多付是因为 logo 提醒顾客的消费能力，那么反之，当一个人有还贷压力时，logo也会提醒他，则会少付小费，就是B选项。
重点是 logo 对小费多少的影响。
也就是说，如果假设成立，正反两种情况应该不相违背。

希望有所帮助~
