【文章內(nèi)容簡介】 5Q12.In Kantovia, physicians’ ine es from insurance panies, which require physicians to document their decisions in treating patients and to justify deviations from the panies’ treatment guidelines. Ten years ago physicians were allowed more discretion. Most physicians believe that the panies’ requirements now prevent them from spending enough time with patients. Yet the average amount of time a patient spends with a physician during an office visit has actually increased somewhat over the last ten years.Which of the following, if true, most helps to resolve the apparent discrepancy between physicians’ perceptions and the change in the actual time spent?A. Patients are more likely to be in a hurry nowadays and are less willing to wait a long time to see their physician.B. Physicians today typically have a wider range of options in diagnosis and treatment to consider with the patient before prescribing.C. Physicians are increasingly likely to work in group practices, sharing the responsibility of night and weekend work.D. Most patients would rather trust their physicians than their insurance panies to make decisions about their treatment.E. Since the insurance panies pay physicians a set amount for each office visit, it is to physicians’ financial advantage to see as many patients as possible.1317 GWD25Q 13 to 15: Grassland songbirds often nest in the same grasslandwetland plexes as waterfowl, particularly in a certain part of those plexes, namely, upland habitats surrounding wetlands. Although some wildlife management procedures directed at waterfowl, such as habitat enhancement or restoration, may also benefit songbirds, the impact of others, especially the control of waterfowl predators, remains difficult to predict. For example, most predators of waterfowl nests prey opportunistically on songbird nests, and removing these predators could directly increase songbird nesting success. Alternatively, small mammals such as mice and ground squirrels are important in the diet of many waterfowlnest predators and can themselves be important predators of songbird nets. Thus. Removing waterfowlnest predators could affect songbird nesting success through subsequent increases in smallmammal populations. In 1995 and 1996, researchers trapped and removed certain waterfowlnest predators, primary raccoons and striped skunks, then observed subsequent survival rates for songbird nests. Surprisingly. They observed no significant effect on songbird nesting success. This may be due to several factors. Neither raccoons nor striped skunks consume ground squirrels, which are important predators of songbird nests. Thus, their removal may not have led to significant increases in populations of smaller predators. Additionally, both raccoons and striped skunks prefer wetlands and spend little time in upland habitats。 removing these species may not have increased the nesting success of songbirds in the uplands enough to allow detection.Q 13:According to the passage, which of the following is true about the role played by ground squirrels in the ecology of grasslandwetland plexes?A. While not important in the diet of raccoons or striped skunks, ground squirrels are a significant source of food for other waterfowlnest predators.B. Whereas ground squirrels are typically important as predators of songbird nests, their opportunistic predation on waterfowl nests also has an observable effect on waterfowl nesting success.C. Although most waterfowlnest predators prey on small mammals such as mice and ground squirrels, populations of ground squirrels tend to increase quickly enough to pensate for this level of predation.D. Although ground squirrels have been known to prey on songbird nests, a larger portion of their diets is usually provided by predation on waterfowl nests.E. Since larger predators tend to prefer small mammals to songbird eggs as a food source, a large population of ground squirrels plays an important role in controlling opportunistic predation on songbird nests.Q 14: Which of the following best describes the function of the sentence “Neither raccoons…songbird nests” (lines 3437) in the context of the passage as a whole?A. It raises questions about the validity of a theory described in the first paragraph. B. It points out an oversimplification that is inherent in the argument presented in the first paragraph.C. It introduces information that may help explain the results of the experiment that are presented earlier in the paragraph.D. It provides a specific example of the type of data collected in the experiment described earlier in the paragraph.E. It anticipates a potential objection to the conclusions drawn by the researchers involved in the experiment described earlier in the paragraph.Q 15:The primary purpose of the passage is toA. describe some procedures used for wildlife management and consider some problems associated with the execution of those proceduresB. outline a problem related to a wildlife management procedure and offer potential explanations for the results of an experiment bearing on that problemC. present experimental results that illustrate the need for certain wildlife management procedures and point out some inconsistencies in those resultsD. argue that a certain procedure used for wildlife management should be modified because of its unintended consequencesE. propose that further experiments be performed to assess the longterm effects of certain wildlife management proceduresQ16:TTGWD27Q32 The passage suggests that
