Guidebook writer: I have visited hotels throughout the country and have noticed that in those built before 1930 the quality of the original carpentry work is generally superior to that in hotels built afterward. Clearly carpenters working on hotels before 1930 typically worked with more skill, care, and effort than carpenters who have worked on hotels built subsequently.
Which of the following, if true, most seriously weakens the guidebook writer’s argument?
A. The quality of original carpentry in hotels is generally far superior to the quality of original carpentry in other structures, such as houses and stores. B. Hotels built since 1930 can generally accommodate more guests than those built before 1930. C. The materials available to carpenters working before 1930 were not significantly different in quality from the materials available to carpenters working after 1930. D. The better the quality of original carpentry in a building, the less likely that building is to fall into disuse and be demolished. E. The average length of apprenticeship for carpenters has declined significantly since 1930. key

When a new restaurant, Martin’s Cafe, opened in Riverville last year, many people predicted that business at the Wildflower Inn, Riverville’s only other restaurant, would suffer from the competition. Surprisingly, however, in the year since Martin’s Cafe opened, the average number of meals per night served at the Wildflower Inn has increased significantly.
Which of the following, if true, most helps to explain the increase?
A. Unlike the Wildflower Inn, Martin’s Cafe serves considerably more meals on weekends than it does on weekdays. B. Most of the customers of Martin’s Cafe had never dined in Riverville before this restaurant opened, and on most days Martin’s Cafe attracts more customers than it can seat. C. The profit per meal is higher, on average, for meals served at Martin’s Cafe than for those served at the Wildflower Inn. D. The Wildflower Inn is not open on Sundays, and therefore Riverville residents who choose to dine out on that day must either eat at Martin’s Cafe or go to neighboring towns to eat. E. A significant proportion of the staff at Martin’s Cafe are people who formerly worked at the Wildflower Inn and were hired away by the owner of Martin’s Cafe. key:B

Historian: In the Drindian Empire, censuses were conducted annually to determine the population of each village. Village census records for the last half of the 1600’s are remarkably complete. This very completeness makes one point stand out; in five different years, villages overwhelmingly reported significant population declines. Tellingly, each of those five years immediately followed an increase in a certain Drindian tax. This tax, which was assessed on villages, was computed by the central government using the annual census figures. Obviously, whenever the tax went up, villages had an especially powerful economic incentive to minimize the number of people they recorded; and concealing the size of a village’s population from government census takers would have been easy. Therefore, it is reasonable to think that the reported declines did not happen.
In the historian’s argument, the two portions in boldface play which of the following roles?
A. The first supplies a context for the historian’s argument; the second acknowledges a consideration that has been used to argue against the position the historian seeks to establish. B. The first presents evidence to support the position that the historian seeks to establish; the second acknowledges a consideration that has been used to argue against that position. C. The first provides a context for certain evidence that supports the position that the historian seeks to establish; the second is that position. D. The first is a position for which the historian argues; the second is an assumption that serves as the basis of that argument. E. The first is an assumption that the historian explicitly makes in arguing for a certain position; the second acknowledges a consideration that calls that assumption into question. key:C

Political Advertisement:
Mayor Delmont’s critics complain about the jobs that were lost in the city under Delmont’s leadership. Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office. So there can be no question that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger.
Which of the following, if true, most strengthens the argument in the advertisement?
A. The average pay for jobs created in the city during the past three years was higher than the average pay for jobs created in the city earlier in Mayor Delmont’s tenure. B. Average pay in the city was at a ten-year low when Mayor Delmont took office. C. Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again. D. The average pay for jobs eliminated in the city during Mayor Delmont’s tenure has been roughly equal every year to the average pay for jobs citywide. E. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city. key:C 對答案質疑
Capuchin monkeys often rub their bodies with a certain type of millipede. Laboratory tests show that secretions from the bodies of these millipedes are rich in two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate capuchins. Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes.
Which of the following, if true, provides the most support for the scientists’ hypothesis?
A. A single millipede often gets passed around among several capuchins, all of whom rub their bodies with it. B. The two chemicals that repel mosquitoes also repel several other varieties of insects. C. The capuchins rarely rub their bodies with the millipedes except during the rainy season, when mosquito populations are at their peak. D. Although the capuchins eat several species of insects, they do not eat the type of millipede they use to rub their bodies. E. The two insect-repelling chemicals in the secretions of the millipedes are carcinogenic for humans but do not appear to be carcinogenic for capuchins. key:E 求教思路
