All electronic messages in a large corporation are transmitted by means of a message network that connects eight computers-Q, R, S, T, W, X. Y, and Z. All of the connections are two-way, so that messages can be sent back and forth between any two connected computers. Any given message enters and leaves a given computer at most once. The computers are connected only in the following way:
Q is connected to R and to T.
S is connected to R and to T
W is connected to S and to Y.
X is connected to S, to Y, and to Z.
The path followed by messages sent from Y to Z must include which of the following computers?
Q
R
S
W
X
答案：(E)
Messages sent from Q to W can go along any of the following paths EXCEPT
Q to R to S to W
Q to T to S to W
Q to R to S to T to W
Q to R to S to X to Y to W
Q to T to S to X to Y to W
答案：(C)
Which of the following specifies in its entirety a sequence, from first to last, of computers through which a message from Z to T can pass?
Z, Q, T
Z, X, Q, T
Z, X, Y, T
Z, X, S, R, T
Z, X, Y, W, S, T
答案：(E)
What is the minimum number of computers, excluding the originating and destination computers, through which a message from T to X must pass?
One

答案：(A)
Disconnecting which of the following computers from every computer to which it is connected would leave exactly one of the other computers unconnected to the rest of the message network?
Q
R
W
X
Z
答案：(D)
A message from one of the computers to another is to be transmitted through all of the other computers, with each transmitting computer sending the message to only one other computer. Which of the following pairs could be the originating computer and the computer finally receiving the message?
Q and W
Q and Z
R and Z
W and T
W and Z

Pauline and Lorraine are paid the same amount of wages per hour for working at the same company, but Pauline has a more difficult job than Lorraine.Pauline argues that because her job is more difficult, the company should pay her more than it pays Lorraine.
Which of the following statements best supports Pauline s argument?
Lorraine is not opposed to being paid less than Pauline.
The company s pay scale is intended to compensate more difficult work with higher wages.
Pauline expects to be promoted to a higher-paying position.
Lorraine was paid more than either woman expected Lorraine to be paid.
Pauline has fewer years of experience in her current job than Lorraine has in hers.
答案：(B)
Scientists warn of a global warming,a "greenhouse effect" resulting from increased atmospheric pollutants, including carbon dioxide from the burning of wood, coal, and oil. A coal-industry spokesperson says that the effect need not cause concern in the near future if, as some scientists believe, the Earth faces another ice age within the next thousand years, since each calamity could cancel out the other.
Which of the following, if true, casts the most serious doubt on the conclusion of the spokesperson?
There is a generally cyclical pattern in the recurrence of ice ages on Earth.
The disastrous results of the greenhouse effect have begun to occur and will probably intensify within the next fifty years.
Trees absorb some of the carbon dioxide in the lower atmosphere and produce oxygen, which is not a pollutant.
Much of the carbon dioxide currently being produced comes not from coal but from the burning of trees cleared from large areas of tropical rain forest.
The greenhouse effect is a scientific conjecture based on incomplete data about gases in the upper atmosphere and on a theory about how those gases could affect the heat from the Sun.
答案：(B)
问题: 下面哪一个如果正确的话,最反对spokesperson的结论?
读题: (注意spokesperson的结论的结论是什么)
科学家警告全球的温暖趋势，由越来越多的大气污染，包括燃烧木材，煤和石油释放的二氧化碳导致的＂温室效应＂. 煤炭工业的发言人说在不远的将来，这种效果没有必要引起关心，如果正如一些科学家相信的那样，地球在下一个千年内将面临另外一个冰川时期，因为每一个灾难能够互相抵消
分析: 文中最后一行的since引导的是原因:
原因: 地球在下一个千年将面临另外一个冰川时期, 而每一个灾难能够互相抵消spokesman的结论: 这种效果没有必要引起关心
这种存在明显since, because原因指示词的题目，往往是直接反对原因.
B. 温室效应灾难性的影响已经开始发生了，并且在下一个50年内会加剧(直接反对两个灾难会相互抵消的原因，温室效应已经开始了)
D. 讨论二氧化碳的来源，无关选项.
E. 温室效应是一个科学推测，基于关于上层大气中不完整的数据和关于那些气体如何影响来自太阳热量的理论.(有点support的味道, support要达到的效果是这种effect的确没有必要引起关心,而e恰恰说明这种温室效应灾难并不一定有,因此也就没有必要引起关心了.)
Although part of the ivory available on world markets was taken from wild elephants that were killed illegally, some ivory is derived from sources that nearly all nations define as legal, such as elephants that have died natural deaths.The world s few remaining wild elephant herds, therefore, are not endangered when those buying ivory at wholesale make a serious effort to limit their purchases to such legal ivory.
The argument above depends on the assumption that
wholesale buyers attempting to limit their purchases to legal ivory can reliably distinguish legal from illegal ivory
the demand for products made from legal ivory will continue to grow in the near future
there are currently fewer wholesale sources of legal ivory in the world than there are of illegal ivory
wholesale buyers of ivory products are generally unaware of the reasons for the dwindling world supply of ivory
a continued supply of legal ivory is ensured because elephants reproduce in captivity
答案：(A)
问题:上面的论述所依赖的假设?
读题:尽管世界市场上可以获得的部分象牙来自与非法捕杀的野象,但是有些象牙来自于几乎所有国家都定义为合法的来源，比如说大象的自然死亡. 当那些在批发市场上购买象牙的人努力限制他们的购买在合法象牙的时候, 世界上剩下的很少的野象群就不会受到危害了.
分析: 倒数第四行therefore引导结论
结论：世界上的野生象群就不会受到危害了.
原因：购买象牙的人努力限制他们的购买在合法象牙
Assumption:
直接: 1. 购买合法象牙和野象没有危害的联系（桥梁关系）
2. 能够购买合法象牙的可行性有意义
没有其他原因:除了限制他们的购买在合法象牙之外, 不再有别的原因影响野生象群的生命
a. 试图限制他们的购买在合法象牙的批发商能够可靠地分清合法象牙和非法象牙(恰恰说明原因是可行的.可以在A中加入not,发现结论就不成立)
