题目：
A newly discovered painting seems to be the work of one of two seventeenth-century artists, either the northern German Johannes Drechen or the Frenchman Louis Birelle, who sometimes painted in the same style as Drechen. Analysis of the carved picture frame, which has been identified as the painting’s original seventeenth-century frame, showed that it is made of wood found widely in northern Germany at the time, but rare in the part of France where Birelle lived. This shows that the painting is most likely the work of Drechen.
Which of the following is an assumption that the argument requires?
Which of the following is an assumption that the argument requires?
选项:
A、The frame was made from wood local to the region where the picture was painted.
B、Drechen is unlikely to have ever visited the home region of Birelle in France.
C、Sometimes a painting so resembles others of its era that no expert is able to confidently decide who painted it.
D、The painter of the picture chose the frame for the picture.
E、The carving style of the picture frame is not typical of any specific region of Europe.

The general availability of high-quality electronic scanners and color printers for computers has made the counterfeiting of checks much easier. In order to deter such counterfeiting, several banks plan to issue to their corporate customers checks that contain dots too small to be accurately duplicated by any electronic scanner currently available; when such checks are scanned and printed, the dots seem to blend together in such a way that the word "VOID" appears on the check.
题目：
A questionable assumption of the plan is that
选项:
A、in the territory served by the banks the proportion of counterfeit checks that are made using electronic scanners has remained approximately constant over the past few yearsmost counterfeiters who use electronic scanners counterfeit checks only for relatively large amounts of money
B、the smallest dots on the proposed checks cannot be distinguished visually except under strong magnification
C、most corporations served by these banks will not have to pay more for the new checks than for traditional checks
D、the size of the smallest dots that generally available electronic scanners are able to reproduce accurately will not decrease significantly in the near future

文章：
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 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 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 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 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 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 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 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 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 considered to have become reservations.

题目：
The passage suggests that, if the criteria discussed in highlight text were the only criteria for establishing a reservation’s water rights, which of the following would be true?
选项:
A、The water rights of the inhabitants of the Fort Belknap Indian Reservation would not take precedence over those of other citizens.Reservations established before 1848 would be judged to have no water rights.
B、There would be no legal basis for the water rights of the Rio Grande pueblos.
C、Reservations other than American Indian reservations could not be created with reserved water rights.
D、Treaties establishing reservations would have to mention water rights explicitly in order to reserve water for a particular purpose.

C

文章：
| Line | Micro-wear patterns found on the teeth of long- |
| extinct specimens of the primate species | |
| australopithecine may provide evidence about their | |
| diets. For example, on the basis of tooth micro-wear | |
| (5) | patterns, Walker dismisses Jolly’s hypothesis that |
| australopithecines ate hard seeds. He also disputes | |
| Szalay’s suggestion that the heavy enamel of | |
| australopithecine teeth is an adaptation to bone | |
| crunching, since both seed cracking and bone | |
| (10) | crunching produce distinctive micro-wear |
| characteristics on teeth. His conclusion that | |
| australopithecines were frugivores (fruit eaters) is | |
| based upon his observation that the tooth micro- | |
| wear characteristics of east African | |
| (15) | australopithecine specimens are indistinguishable |
| from those of chimpanzees and orangutans, which | |
| are commonly assumed to be frugivorous primates. | |
| However, research on the diets of | |
| contemporary primates suggests that micro-wear | |
| (20) | studies may have limited utility in determining the |
| foods that are actually eaten. For example, insect | |
| eating, which can cause distinct micro-wear | |
| patterns, would not cause much tooth abrasion in | |
| modern baboons, who eat only soft-bodied insects | |
| (25) | rather than hard-bodied insects. In addition, the |
| diets of current omnivorous primates vary | |
| considerably depending on the environments that | |
| different groups within a primate species inhabit; if | |
| australopithecines were omnivores too, we might | |
| (30) | expect to find considerable population variation in |
| their tooth micro-wear patterns. Thus, Walker’s | |
| description of possible australopithecine diets may | |
| need to be expanded to include a much more | |
| diverse diet. |
