题目：

Over the past two decades, a wide gap in pay has arisen between medical professionals who practice in the public health arena as opposed to those who practice privately. As a result, many doctors, nurses and other health professionals employed by public and nonprofit agencies have left their public health jobs in favor of private clinics and hospitals. Public and nonprofit agencies will be able to entice these professionals to return to public health jobs if salaries are made commensurate with those paid in the private sector. The quality of medical care provided by public and nonprofit agencies will thus be improved.
Which one of the following is presumed in the position stated above?

选项:

A、A. The experience obtained by medical professionals in private clinics and hospitals will be especially important in the public health arena.
B、B. How well public and nonprofit health agencies perform depends for the most part upon the experience level of their health professionals.
C、C. Unless public and nonprofit health agencies act, the salaries paid to medical professionals in private practice will continue to outpace those paid in the public health arena.
D、D. Medical health professionals who moved from the public sector to the private sector would change jobs again.
E、E. If the pay disparity between the public and private medical sectors continues to increase, many doctors and nurses will move from private practice to the public health area.

D

题目：

Urban planner: When a city loses population due to migration, property taxes in that city tend to rise. This is because there are then fewer residents paying to maintain an infrastructure that was designed to support more people. Rising property taxes, in turn, drive more residents away, compounding the problem. Since the city of Stonebridge is starting to lose population, the city government should therefore refrain from raising property taxes.

Which of the following, if true, would most weaken the urban planner's argument?

选项:

A、
A. If Stonebridge does not raise taxes on its residents to maintain its infrastructure, the city will become much less attractive to live in as that infrastructure decays.
B、
B. Stonebridge at present benefits from grants provided by the national government to help maintain certain parts of its infrastructure.
C、
C. If there is a small increase in property taxes in Stonebridge and a slightly larger proportion of total revenue than at present is allocated to infrastructure maintenance, the funding will be adequate for that purpose.
D、
D. Demographers project that the population of a region that includes Stonebridge will start to increase substantially within the next several years.
E、
E. The property taxes in Stonebridge are significantly lower than those in many larger cities.

A

题目：

Press Secretary: Our critics claim that the President's recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties. They offer as evidence the fact that 90 percent of the projects canceled were in such districts. But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors. So the President's choice was clearly motivated by sound budgetary policy, not partisan politics.

Which of the following is an assumption on which the press secretary's argument depends?

选项:

A、Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties.
B、The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President's party.
C、The number of projects canceled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future.
D、The highway projects canceled in districts controlled by the President's party were not generally more expensive than the projects canceled in districts controlled by opposition parties.
E、Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessments of government projects.

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.
 
Which of the following, if discovered in experiments using artificially moved prey insects, would support one of the two hypotheses and undermine the other?
