文章：

Line         In Winters v. United States (1908), the Supreme
  Court held that the right to use waters flowing through
  or adjacent to the Fort Belknap Indian Reservation
  was reserved to American Indians by the treaty
(5) establishing the reservation. Although this treaty did
  not mention water rights, the Court ruled that the
  federal government, when it created the reservation,
  intended to deal fairly with American Indians by
  reserving for them the waters without which their
(10) lands would have been useless. Later decisions, citing
  Winters, established that courts can find federal rights
  to reserve water for particular purposes if (1) the
  land in question lies within an enclave under exclusive
  federal jurisdiction, (2) the land has been formally
(15) withdrawn from federal public lands—i.e., withdrawn
  from the stock of federal lands available for private
  use under federal land use laws—and set aside
  or reserved, and (3) the circumstances reveal the
  government intended to reserve water as well as land
(20) when establishing the reservation.
       Some American Indian tribes have also established
  water rights through the courts based on their
  traditional diversion and use of certain waters prior
  to the United States’ acquisition of sovereignty. For
(25) example, the Rio Grande pueblos already existed
  when the United States acquired sovereignty over
  New Mexico in 1848. Although they at that time
  became part of the United States, the pueblo lands
  never formally constituted a part of federal public
(30) lands; in any event, no treaty, statute, or executive
  order has ever designated or withdrawn the pueblos
  from public lands as American Indian reservations.
  This fact, however, has not barred application of the
  Winters doctrine. What constitutes an American Indian
(35) reservation is a question of practice, not of legal
  definition, and the pueblos have always been treated
  as reservations by the United States. This pragmatic
  approach is buttressed by Arizona v. California (1963),
  wherein the Supreme Court indicated that the manner
(40) in which any type of federal reservation is created
  does not affect the application to it of the Winters
  doctrine. Therefore, the reserved water rights of
  Pueblo Indians have priority over other citizens’ water
  rights as of 1848, the year in which pueblos must be
(45) considered to have become reservations.


题目：

The author cites the fact that the Rio Grande pueblos were never formally withdrawn from public lands primarily in order to do which of the following?

选项:

A、Suggest why it might have been argued that the Winters doctrine ought not to apply to pueblo lands
B、Imply that the United States never really acquired sovereignty over pueblo lands
C、Argue that the pueblo lands ought still to be considered part of federal public lands
D、Support the argument that the water rights of citizens other than American Indians are limited by the Winters doctrine
E、Suggest that federal courts cannot claim jurisdiction over cases disputing the traditional diversion and use of water by Pueblo Indians

A

题目：

A study of ticket sales at a summer theater festival found that people who bought tickets to individual plays had a no-show rate of less than 1 percent, while those who paid in advance for all ten plays being performed that summer had a no-show rate of nearly 30 percent. This may be at least in part because the greater the awareness customers retain about the cost of an item, the more likely they are to use it.

Which of the following would, if true, best serve as an alternative explanation of the results of the study?

选项:

A、The price per ticket was slightly cheaper for those who bought all ten tickets in advance.
B、Many people who attended the theater festival believed strongly that they should support it financially.
C、Those who attended all ten plays became eligible for a partial refund.
D、Usually, people who bought tickets to individual plays did so immediately prior to each performance that they attended.
E、People who arrived just before the performance began could not be assured of obtaining seats in a preferred location.

D

文章：

Jon Clark’s study of the effect of the modernization of a telephone exchange on exchange maintenance work and workers is a solid contribution to a debate that encompasses two lively issues in the history and sociology of technology: technological determinism and social constructivism.

Clark makes the point that the characteristics of a technology have a decisive influence on job skills and work organization. Put more strongly, technology can be a primary determinant of social and managerial organization. Clark believes this possibility has been obscured by the recent sociological fashion, exemplified by Braverman’s analysis, that emphasizes the way machinery reflects social choices. For Braverman, the shape of a technological system is subordinate to the manager’s desire to wrest control of the labor process from the workers. Technological change is construed as the outcome of negotiations among interested parties who seek to incorporate their own interests into the design and configuration of the machinery. This position represents the new mainstream called social constructivism.

The constructivists gain acceptance by misrepresenting technological determinism: technological determinists are supposed to believe, for example, that machinery imposes appropriate forms of order on society. The alternative to constructivism, in other words, is to view technology as existing outside society, capable of directly influencing skills and work organization.

Clark refutes the extremes of the constructivists by both theoretical and empirical arguments. Theoretically he defines "technology" in terms of relationships between social and technical variables. Attempts to reduce the meaning of technology to cold, hard metal are bound to fail, for machinery is just scrap unless it is organized functionally and supported by appropriate systems of operation and maintenance. At the empirical level Clark shows how a change at the telephone exchange from maintenance-intensive electromechanical switches to semi-electronic switching systems altered work tasks, skills, training opportunities, administration, and organization of workers. Some changes Clark attributes to the particular way management and labor unions negotiated the introduction of the technology, whereas others are seen as arising from the capabilities and nature of the technology itself. Thus Clark helps answer the question: "When is social choice decisive and when are the concrete characteristics of technology more important?"

选项:

A、advocate a more positive attitude toward technological changediscuss the implications for employees of the modernization of a telephone exchange
B、consider a successful challenge to the constructivist view of technological change

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.

What was the dealer's approximate profit or loss as a percent of the dealer's initial cost for the 60 cameras?
