8. The stable functioning of a society depends upon the relatively long-term stability of the goals of its citizens. This is clear from the fact that unless the majority of individuals have a predictable and enduring set of aspirations, it will be impossible for a legislature to craft laws that will augment the satisfaction of the citizenry, and it should be obvious that a society is stable only if its laws tend to increase the happiness of its citizens. The claim that a society is stable only if its laws tend to increase the happiness of its citizens plays which one of the following roles in the argument? (A) It is the conclusion of the argument. (B) It helps to support the conclusion of the argument. (C) It is a claim that must be refuted if the conclusion is to be established. (D) It is a consequence of the argument. (E) It is used to illustrate the general principle that the argument presupposes. 想知道B和E的区别。为什么不能理解为。第一句是个general principle....然后中间说的那个就是用来illustrate的？。。。。。？？

23. On a certain day, nine scheduled flights on Swift Airlines were canceled. Ordinarily, a cancellation is due to mechanical problems with the airplane scheduled for a certain flight. However, since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day, some of the nine cancellations were probably due to something else. The argument depends on which one of the following assumptions? (A) More than one or two airplanes were scheduled for the nine canceled flights. (B) Swift Airlines has fewer mechanical problems than do other airlines of the same size. (C) Each of the canceled flights would have been longer than the average flight on Swift Airlines. (D) Swift Airlines had never before canceled more than one or two scheduled flights on a single day. (E) All of the airplanes scheduled for the canceled flights are based at the same airport.
这题我就不懂schedule到底是什么意思啊？题目就看不懂，是想说9架取消的飞机里面重新安排的吗？
58. Some people say that the scarcity of food is a function of the finite limits of the earth’s resources, coupled with a relentless rate of population growth. This analysis fails to recognize, however, that much of the world’s agricultural resources are used to feed livestock instead of people. In the United States, for example, almost one-half of the agricultural acreage is devoted to crops fed to livestock. A steer reduces twenty-one pounds of inexpensive grain to one pound of expensive meat. Thus, the scarcity of food is not merely a function of limited resources and population growth. Which one of the following is an assumption that would allow the conclusion in the argument to be properly drawn? (A) People prefer eating meat to eating grain. (B) Meat is twenty-one times more expensive than grain. (C) The limits of the earth’s agricultural resources are not finite. (D) More than one-half of the agricultural acreage in the United States is devoted to drops fed to humans. (E) Growing crops for human consumption on the acreage currently devoted to crops for livestock will yield more food for more people.
63. Some good cooks are gourmet cooks who pride themselves on always using extravagantly rich ingredients in elaborate recipes. Some good cooks can be characterized as fast-food cooks. They may use rich ingredients as long as the recipes are easy to follow and take little time. Other good cooks are health food enthusiasts, who are concerned primarily with the nutritional value of food. But even though not all good cooks are big eaters they all enjoy preparing and serving food. If the information in the passage is true, which one of the following CANNOT be true? (A) Most good cooks do not use extravagantly rich ingredients. (B) Everyone who enjoys preparing and serving food is a good cook. (C) More good cooks who use extravagantly rich ingredients are big eaters than are good cooks who do not use such ingredients. (D) There are fewer good cooks who enjoy serving and preparing food than there are good cooks who are big eaters. (E) Gourmet cooks, fast-food cooks, and cooks who are health food enthusiasts are all big eaters. 答案说是D，说E是对的。还说从原文退出来。E是怎么推出来的？！！！！我退不出。不是原文说，notall good cooks are big eaters.
