GWD-24-Q 22: Often patients with ankle fractures that are stable, and thus do not
require surgery, are given follow-up x-rays because their orthopedists
are concerned about possibly having misjudged the stability of the fracture. When a number of follow-up x-rays were reviewed, however, all
the fractures that had initially been judged stable were found to have
healed correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable.
Which of the following, if true, most strengthens the argument?
A. Doctors who are general practitioners rather than orthopedists are
less likely than orthopedists to judge the stability of an ankle fracture correctly. B. Many ankle injuries for which an initial x-ray is ordered are revealed
by the x-ray not to involve any fracture of the ankle. C. X-rays of patients of many different orthopedists working in several
hospitals were reviewed. D. The healing of ankle fractures that have been surgically repaired is
always checked by means of a follow-up x-ray. E. Orthopedists routinely order follow-up x-rays for fractures of bone
other than ankle bones. --------------------------------------------------------------------------------------------------
T-9-Q18. The growing popularity of computer-based activities was widely expected to result in a decline in television viewing, since it had been assumed that people lack sufficient free time to maintain current television-viewing levels while spending increasing amounts of free time on the computer. That assumption, however, is evidently false: in a recent mail survey concerning media use, a very large majority of respondents who report increasing time spent per week using computer report no change in time spent watching television.
Which of the following would be most useful to determine in order to evaluate the argument?
A. Whether a large majority of the survey respondents reported watching television regularly B. Whether the amount of time spent watching television is declining among people who report that they rarely or never use computers C. Whether the type of television programs a person watches tends to changes as the amount of time spent per week using computer increases D. Whether a large majority of the computer owners in the survey reported spending increasing amounts of time per week using computers E. Whether the survey respondents’ reports of time spent using computers included time spent using computers at work.
A为什么不对 Which of the following, if true, most logically completes the passage? A recent poll found that over 80 percent of the residents of Nalmed Province favored a massive expansion of the commuter rail system as a means of significantly easing congestion on the province’s highways and were willing to help pay for the expansion through an increase in their taxes. Nevertheless, the poll results indicate that expansion of the rail system, if successfully completed, would be unlikely to achieve its goal of easing congestion, because . A. most of people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience. B. of the less than 20 percent of residents not counted as favoring the expansion, about half claimed to have no opinion one way or the other. C. the twice-daily periods of peak congestion caused by people commuting in cars have grown from about an hour each to almost two and a half hours each in the past 20 years. D. expanding the commuter rail system will require the construction of dozens of miles of new railroads. E. the proposed expansion to the commuter rail system will make it possible for some people who both live and work at suburban locations to commute by rail. 这个A是什么意思？想不明白 11. GWD17-Q11:
Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species. Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates. Clearly, dropping this restriction would allow the other species to recover.
Which of the following, if true, most seriously undermines the argument?
A. Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese. B. It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date. C. The number of snow geese taken by hunters each year has grown every year for several years. D. As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons. E. In the snow goose’s winter habitats, the goose faces no significant natural predation.
