2、lan to have several modern office buildings constructed and to offer reduced local tax rates to any business that leases space in a new downtown building.Which of the following, if true, most threatens the plans likelihood of success?（A） Most of the businesses currently located in downtown Villieu h

3、ave long-term leases on the space they occupy there.（B） The existing office buildings in downtown Villieu have, on average, a much higher vacancy rate than do office buildings in Villieus suburbs.（C） The local tax rates in Villieus suburbs are significantly lower than downtown Villieus proposed rate

4、 for businesses that lease space in the new office buildings.（D） Most of the businesses that currently lease office space in downtown Villieu also lease office space in Villieu（E） With the new office buildings, downtown Villieu would have a greater amount of modern office space than any other downto

5、wn business district in the region.3. （24117-!000708）Northern Air has dozens of flights daily into and out of Belleville Airport, which is highly congested. Northern Air depends for its success on economy and quick turnaround and consequently is planning to replace its large planes with Skybuses, wh

6、ose novel aerodynamic design is extremely fuel efficient. The Skybus fuel efficiency results in both lower fuel costs and reduced time spent refueling.Which of the following, if true, could present the most serious disadvantage for Northern Air in replacing their large planes with Skybuses?（A） The S

7、kybus would enable Northern Air to schedule direct flights to destinations that currently require stops for refueling.（B） Aviation fuel is projected to decline in price over the next several years.（C） The fuel efficiency of the Skybus would enable Northern Air to eliminate refueling at some of its d

8、estinations, but several mechanics would lose their jobs.（D） None of Northern Airs competitors that use Belleville Airport are considering buying Skybuses.（E） The aerodynamic design of the Skybus causes turbulence behind it when taking off that forces other planes on the runway to delay their takeof

These workers have heard, however, that the company is buying 100 new computers. So the workers concluded that the companys real reason for laying them off is

10、to fill their jobs with lower-paid workers.Which of the following, if true, would most undermine the workers conclusion?（A） Most of the workers being laid off know how to enter data on a number of different computer systems.（B） Orders for almost all of Beta Corporation products have increased over t

11、he past year.（C） A recent memorandum from the president of Beta Corporation requested that all data generated by the company be stored in computerized form.（D） Beta Corporations computer data-entry workers are more experienced and hence more highly paid than people doing comparable work in other com

12、panies.（E） Beta Corporations new computers will allow its current management and sales staff to perform many of the tasks that the data-entry workers were previously doing.13. （25752-!002668）An unusually severe winter occurred in Europe after the continent was blanketed by a blue haze resulting from

13、 the eruption of the Laki Volcano in the European republic of Iceland in the summer of 1984. Thus, it is evident that major eruptions cause the atmosphere to become cooler than it would be otherwise.Which of the following statements, if true, most seriously weakens the argument above?（A） The cooling

14、 effect triggered by volcanic eruptions in 1985 was counteracted by an unusual warming of Pacific waters.（B） There is a strong statistical link between volcanic eruptions and the severity of the rainy season in India.（C） A few months after El Chichns large eruption in April 1982, air temperatures th

15、roughout the region remained higher than expected, given the long-term weather trends.（D） The climatic effects of major volcanic eruptions can temporarily mask the general warming trend resulting from an excess of carbon dioxide in the atmosphere.（E） Three months after an early springtime eruption i

16、n South America during the late 19th century, sea surface temperatures near the coast began to fall.15. （25986-!002914）Some airlines allegedly reduce fares on certain routes to a level at which they lose money, in order to drive competitors off those routes. However, this method of eliminating compe

17、tition cannot be profitable in the long run. Once an airline successfully implements this method, any attempt to recoup the earlier losses by charging high fares on that route for an extended period would only provide competitors with a better opportunity to undercut the airlines fares.Which of the

18、following, if true, most seriously weakens the argument?（A） In some countries it is not illegal for a company to drive away competitors by selling a product below cost.（B） Airline executives generally believe that a company that once underpriced its fares to drive away competitors is very likely to

19、do so again if new competitors emerge.（C） As part of promotions designed to attract new customers, airlines sometimes reduce their ticket prices to below an economically sustainable level.（D） On deciding to stop serving particular routes, most airlines shift resources to other routes rather than red

20、uce the size of their operations.（E） When airlines dramatically reduce their fares on a particular route, the total number of air passengers on that route increases greatly.22. （28162-!003858）Herbicides allow cereal crops to be grown very efficiently, with virtually no competition from weeds. In Bri

21、tain, partridge populations have been steadily decreasing since herbicide use became widespread. Some environmentalists claim that these birds, which live in and around cereal crop fields, are being poisoned by the herbicides. However, tests show no more than trace quantities of herbicides in partri

22、dges on herbicide-treated land. Therefore, something other than herbicide use must be responsible for the population decrease.Which of the following, if true about Britain, most seriously weakens the argument?（A） The elimination of certain weeds from cereal crop fields has reduced the population of

23、the small insects that live on those weeds and that form a major part of partridge chicks diet.（B） Since partridges are valued as game birds, records of their population are more carefully kept than those for many other birds.（C） Some of the weeds that are eliminated from cereal crop fields by herbi

24、cides are much smaller than the crop plants themselves and would have no negative effect on crop yield if they were allowed to grow.（D） Birds other than partridges that live in or around cereal crop fields have also been suffering population declines.（E） The toxins contained in herbicides typically

25、used on cereal crops can be readily identified in the tissues of animals that have ingested them.36. （31643-!006431）Traveler: Southern Airways has a far worse safety record than Air Dacentaria over the past few years, in terms of both the frequency of accidents and the severity of accidents. Therefo

26、re, although Air Dacentaria is slightly more expensive, I will choose it over Southern Airways for my flight from Pederton to Dacenta, since it is worth paying extra to have a safer flight.Which of the following, if true, casts the most serious doubt on the travelers argument?（A） Air Dacentarias fli

27、ght from Pederton to Dacenta is nonstop, whereas Southern Airways flight touches down in Gorinda on the way.（B） Most Southern Airways flights, but not its flight from Pederton to Dacenta, use Sarmouth airport, which because of its mountainous location is one of the worlds most dangerous.（C） For its

28、flights from Pederton to Dacenta, Southern Airways uses a different model of airplane, with a smaller capacity, than the model Air Dacentaria uses for its flights on the same route.（D） Only in the last few years has the cost of flying from Pederton to Dacenta been more expensive on Air Dacentaria th

29、an on Southern Airways.（E） Although the frequency of accidents is greater on Southern Airways, on both airlines the proportion of flights that have accidents is very small.38. （32291-!006866）Offshore oil-drilling operations entail an unavoidable risk of an oil spill, but importing oil on tankers pre

30、sently entails an even greater such risk per barrel of oil. Therefore, if we are to reduce the risk of an oil spill without curtailing our use of oil, we must invest more in offshore operations and import less oil on tankers.Which of the following, if true, most seriously weakens the argument above?

31、（A） Tankers can easily be redesigned so that their use entails less risk of an oil spill.（B） Oil spills caused by tankers have generally been more serious than those caused by offshore operations.（C） The impact of offshore operations on the environment can be controlled by careful management.（D） Off

32、shore operations usually damage the ocean floor, but tankers rarely cause such damage.（E） Importing oil on tankers is currently less expensive than drilling for it offshore.39. （32799-!007548）The imposition of quotas limiting imported steel will not help the big American steel mills.
