    In its 1903 decision in the case of Lone Wolf v. Hitchcock, the United States Supreme Court rejected the efforts of three Native American tribes to prevent the opening of tribal lands to non-Indian settlement without tribal consent. In his study of the Lone Wolf case, Blue Clark properly emphasizes the Court's assertion of a virtually unlimited unilateral power of Congress (the House of Representatives and the Senate) over Native American affairs. But he fails to note the decision's more far-reaching impact: shortly after Lone Wolf, the federal government totally abandoned negotiation and execution of formal written agreements with Indian tribes as a prerequisite for the implementation of federal Indian policy. Many commentators believe that this change had already occurred in 1871 when— following a dispute between the House and the Senate over which chamber should enjoy primacy in Indian affairs—Congress abolished the making of treaties with Native American tribes. But in reality the federal government continued to negotiate formal tribal agreements past the turn of the century, treating these documents not as treaties with sovereign nations requiring ratification by the Senate but simply as legislation to be passed by both houses of Congress. The Lone Wolf decision ended this era of formal negotiation and finally did away with what had increasingly become the empty formality of obtaining tribal consent.

题目：

According to the passage, which of the following was true of relations between the federal government and Native American tribes?

选项:

A、Some Native American tribes approved of the congressional action of 1871 because it simplified their dealings with the federal government.
B、Some Native American tribes were more eager to negotiate treaties with the United States after the Lone Wolf decision.
C、Prior to the Lone Wolf decision, the Supreme Court was reluctant to hear cases involving agreements negotiated between Congress and Native American tribes.
D、Prior to 1871, the federal government sometimes negotiated treaties with Native American tribes.
E、Following 1871, the House exercised more power than did the Senate in the government's dealings with Native American tribes.

文章：

Two works published in 1984 demonstrate contrasting approaches to writing the history of United States women. Buel and Buel’s biography of Mary Fish (1736–1818) makes little effort to place her story in the context of recent historiography on women. Lebsock, meanwhile, attempts not only to write the history of women in one southern community, but also to redirect two decades of historiographical debate as to whether women gained or lost status in the nineteenth century as compared with the eighteenth century. Although both books offer the reader the opportunity to assess this controversy regarding women’s status, only Lebsock’s deals with it directly. She examines several different aspects of women’s status, helping to refine and resolve the issues. She concludes that while women gained autonomy in some areas, especially in the private sphere, they lost it in many aspects of the economic sphere. More importantly, she shows that the debate itself depends on frame of reference: in many respects, women lost power in relation to men, for example, as certain jobs (delivering babies, supervising schools) were taken over by men. Yet women also gained power in comparison with their previous status, owning a higher proportion of real estate, for example. In contrast, Buel and Buel’s biography provides ample raw material for questioning the myth, fostered by some historians, of a colonial golden age in the eighteenth century but does not give the reader much guidance in analyzing the controversy over women’s status.

题目：

The author of the passage mentions the supervision of schools primarily in order to

选项:

A、remind readers of the role education played in the cultural changes of the nineteenth century in the United Statessuggest an area in which nineteenth-century American women were relatively free to exercise power
B、provide an example of an occupation for which accurate data about women's participation are difficult to obtain
C、speculate about which occupations were considered suitable for United States women of the nineteenth century
D、illustrate how the answers to questions about women's status depend on particular contexts

题目：

Guillemots are birds of Arctic regions. They feed on fish that gather beneath thin sheets of floating ice, and they nest on nearby land. Guillemots need 80 consecutive snow-free days in a year to raise their chicks, so until average temperatures in the Arctic began to rise recently, the guillemots’ range was limited to the southernmost Arctic coast. Therefore, if the warming continues, the guillemots’ range will probably be enlarged by being extended northward along the coast.

Which of the following, if true, most seriously weakens the argument?

选项:

A、Even if the warming trend continues, there will still be years in which guillemot chicks are killed by an unusually early snow.
B、If the Arctic warming continues, guillemots’ current predators are likely to succeed in extending their own range farther north.
C、Guillemots nest in coastal areas, where temperatures are generally higher than in inland areas.
D、If the Arctic warming continues, much of the thin ice in the southern Arctic will disappear.
E、The fish that guillemots eat are currently preyed on by a wider variety of predators in the southernmost Arctic regions than they are farther north.

D

题目：

Wolves generally avoid human settlements.  For this reason, domestic sheep, though essentially easy prey for wolves, are not usually attacked by them.  In Hylantia prior to 1910, farmers nevertheless lost considerable numbers of sheep to wolves each year.  Attributing this to the large number for wolves, in 1910 the government began offering rewards to hunters for killing wolves.  From 1910 to 1915, large numbers of wolves were killed.  Yet wolf attacks on sheep increased significantly.
 
Which of the following, if true, most helps to explain the increase in wolf attacks on sheep?

选项:

A、Populations of deer and other wild animals that wolves typically prey on increased significantly in numbers from 1910 to 1915.
B、Prior to 1910, there were no legal restrictions in Hylantia on the hunting of wolves.
C、After 1910 hunters shot and wounded a substantial number of wolves, thereby greatly diminishing these wolves' ability to prey on wild animals.
D、Domestic sheep are significantly less able than most wild animals to defend themselves against wolf attacks.
E、The systematic hunting of wolves encouraged by the program drove many wolves in Hylantia to migrate to remote mountain areas uninhabited by humans.

C

题目：

Linguist: In English, the past is described as “behind” and the future “ahead,” whereas in Aymara the past is “ahead” and the future “behind.” Research indicates that English speakers sway backward when discussing the past and forward when discussing the future. Conversely, Aymara speakers gesture forward with their hands when discussing the past and backward when discussing the future. These bodily movements, therefore, suggest that the language one speaks affects how one mentally visualizes time.

The linguist's reasoning depends on assuming which of the following?

选项:

A、At least some Aymara speakers sway forward when discussing the past and backward when discussing the future.
B、Most people mentally visualize time as running either forward or backward.
C、Not all English and Aymara speakers tend to sway or gesture forward or backward when discussing the present.
D、How people move when discussing the future correlates to some extent with how they mentally visualize time.
E、The researchers also examined the movements of at least some speakers of languages other than English and Aymara discussing the past and the future.

D

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?
