(A) One of the species whose members are likely to eat the poison is the red squirrel, a species on which owl

15、s do not prey. (B) The owls whose nesting sites are currently being destroyed by the gray squirrels feed primarily on rodents.

Questions 5-6 Sales manager: Last year the total number of meals sold in our company restaurant

17、s was much higher than it was the year before. Obviously consumers find our meals desirable. Accountant: If you look at individual restaurants, however, you find that the number of meals sold actually decreased substantially at every one of our restaurants that was in operation both last year and th

18、e year before. The desirability of our meals to consumers has clearly decreased, given that this group of restaurants-the only ones for which we have sales figures that permit a comparison between last year and the year before-demonstrates a trend toward fewer sales. 5. If the sales figures cited by

19、 the accountant and the sales manager are both accurate, which one of the following must be true? (A) The company opened at least one new restaurant in the last two years.

(E) Most of the companys restaurants that were in operation throughout both last year and the year before are located in areas where residents experienced a severe overall decli

23、ne in income last year. 7. Problems caused by the leaching of pollutants from dumps and landfills are worst in countries with an annual per capita economic output of $4,000 to $5,000, and less severe for considerably poorer and considerably richer countries. This is so because pollution problems inc

24、rease during the early stages of a countrys industrial development but then diminish as increasing industrial development generates adequate resources to tackle such problems. Therefore, problems caused by such leaching in Country X, where the annual per capita economic output is now $5,000, should

25、begin to diminish in the next few years. Which one of the following is an assumption on which the argument depends? (A) Within the next few years, Country X will impose a system of fines for illegal waste disposal by its industrial companies. (B) Countries surrounding Country X will reduce the amoun

26、t of pollution that their factories release into the air and water. (C) Industrial development in Country X will increase in the next few years.

27、ollution problems that are as severe as those in Country X. 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

28、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.

(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 i

30、s used to illustrate the general principle that the argument presupposes. 9. Astronauts who experience weightlessness frequently get motion sickness. The astronauts see their own motion relative to passing objects, but while the astronauts are weightless their inner ears indicate that their bodies a

31、re not moving. The astronauts experience is best explained by the hypothesis that conflicting information received by the brain about the bodys motion causes motion sickness. Which one of the following, if true, provides the strongest additional support for the hypothesis above? (A) During rough voy

32、ages ship passengers in cabins providing a view of the water are less likely to get motion sickness than are passengers in cabins providing no view. (B) Many people who are experienced airplane passengers occasionally get motion sickness. (C) Some automobile passengers whose inner ears indicate that they are moving and who have a clear view of the objects they are passing get motion sickness.
