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(15) withdrawn from federal public lands—i.e., withdrawn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  order has ever designated or withdrawn the pueblos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：

Which of the following most accurately summarizes the relationship between Arizona v. California in lines 38–42, and the criteria citing the Winters doctrine in lines 10–20 ?

选项:

A、Arizona v. California abolishes these criteria and establishes a competing set of criteria for applying the Winters doctrine.
B、Arizona v. California establishes that the Winters doctrine applies to a broader range of situations than those defined by these criteria.
C、Arizona v. California represents the sole example of an exception to the criteria as they were set forth in the Winters doctrine.
D、Arizona v. California does not refer to the Winters doctrine to justify water rights, whereas these criteria do rely on the Winters doctrine.
E、Arizona v. California applies the criteria derived from the Winters doctrine only to federal lands other than American Indian reservations.

题目：

The symptoms that United States President Zachary Taylor began showing five days before his death are consistent with arsenic poisoning.  Recent examination of Taylor's bones, however, revealed levels of arsenic comparable to those found in the bones of Taylor's contemporaries.  These levels are much lower than the levels of arsenic that remain in the bones of arsenic poisoning victims who live for more than a day after ingesting a lethal dose of the poison.
Which of the following is most strongly supported by the statements given?

选项:

A、The symptoms that Taylor began showing five days before his death are consistent with poisoning other than arsenic poisoning.
B、Taylor's death was not the result of any kind of poisoning.
C、The symptoms that Taylor began showing five days before his death were not caused by a lethal dose of arsenic.
D、The symptoms that Taylor began showing five days before his death grew more severe each day.
E、It is unusual for a person who has ingested a lethal dose of arsenic to survive for more than a day.

文章：

Codex Berinensis, a Florentine copy of an ancient Roman medical treatise, is undated but contains clues to when it was produced. Its first 80 pages are by a single copyist, but the remaining 20 pages are by three different copyists, which indicates some significant disruption. Since a letter in handwriting identified as that of the fourth copyist mentions a plague that killed many people in Florence in 1148, Codex Berinensis was probably produced in that year.

题目：

Which of the following, if true, most strongly supports the hypothesis that Codex Berinensis was produced in 1148?

选项:

A、Other than Codex Berinensis, there are no known samples of the handwriting of the first three copyistsAccording to the account by the fourth copyist, the plague went on for 10 months. 
B、A scribe would be able to copy a page of text the size and style of Codex Berinensis in a day.
C、There was only one outbreak of plague in Florence in the 1100s. 
D、The number of pages of Codex Berinensis produced by a single scribe becomes smaller with each successive change of copyist.

D

文章：

The growing popularity of computer-based activities was widely predicted to result in a corresponding decline in television viewing. Recent studies have found that, in the United States, people who own computers watch, on average, significantly less television than people who do not own computers. In itself, however, this finding does very little to show that computer use tends to reduce television viewing time, since __________.

题目：

Which of the following most logically completes the argument?

选项:

A、many people who watch little or no television do not own a computereven though most computer owners in the United States watch significantly less television than the national average, some computer owners watch far more television than the national average
B、computer owners in the United States predominantly belong to demographic groups that have long been known to spend less time watching television than the population as a whole does 
C、many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television
D、many people use their computers primarily for tasks such as correspondence that can be done more rapidly on the computer, and doing so leaves more leisure time for watching television

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.
