What is the probability his final average is more than 85 16.In the world of art, distinguishing the authentic piece from the forgery is not an easy feat and often requires the use of multiple experts. Millions of dollars can be at stake, yet even experts can be fooled. Howev

15、er, a recent discovery has introduced a new resource for galleries and other groups seeking to establish the origins of their paintings: mathematicians. Math experts were able to analyze digital images of authenticated paintings where they found consistent differences in paint texture. This consiste

16、ncy suggests that each artist has a unique style of brush stroke that cannot be completely duplicated. 17.In many Western European nations, the law is seen as rigid and not open to interpretation. This rigidity grants a consistency to questions of law that many would argue is absent in other, more f

17、lexible systems. The European construction of law provides litigants with a clear picture of how a case will be decided. All parties involved are certain how judges will rule on issues. It is simple-judges will strictly follow the law. This simple fact, that the law will not change from one situatio

18、n to another, allows for court systems in Western Europe to process cases efficiently and cuts down on the amount of frivolous lawsuits. It is useless for an individual to attempt a case if he knows in advance that the law is not in his favor. 18.The water level in a tank is lowered by 6 inches, the

19、n raised by inches, and then lowered by 4 inches. If the water level was x inches before the changes in level, which of the following represents the water level, in inches, after the changes 19.If the radius of a circular region were decreased by 20 percent, the area of the circular region would dec

B.16 C.D. 32 E. 16 21.Eli Whitneys cotton gin famously changed the face of the agricultural industry by greatly incre

21、asing productivity. Although the gin was enormously popular, Whitney himself struggled to make a profit from it. After receiving a patent for his invention, Whitney and his business partner opted to produce as many cotton gins as possible and to charge farmers a user fee instead of selling them outr

22、ight. Farmers considered this fee unnecessary and exorbitant, and began manufacturing copies of the cotton gin instead. Because of a loophole in the patent law, the many lawsuits brought by Whitney and his partner against the farmers were fruitless. The duo finally agreed to license their cotton gin

23、s at a reasonable price. However, due to the costs of their legal battles, they were unable to make the fortune that Whitney had previously predicted. 22.We packed early. An 8 a.m. international flight, especially one to be taken with children, demands strict attention to detail and advance preparat

24、ion. But with that chore finished, it was time to spend one last afternoon in Paris. We chose to see the Louvre. We planned our visit strategically: the Mona Lisa, of course, followed by the Venus De Milo. The Napoleon buff in our party insisted on seeing the Jacques Louis Davids seemingly life-size

25、d painting of the emperors coronation, while the children were thrilled by the Egyptian mummies. I think we walked for miles. Despite the frenetic pace, we saw only a fraction of the museum before it was time to head home-home being a tiny, sixth-floor apartment in the 10th arrondissement. Sitting a

26、mongst our suitcases, we flipped through our souvenirs and swapped stories with our host until bedtime. Lifting a glass toward our window view of a sparkling Eiffel Tower, we toasted each other-and a beautiful day in Paris.Which of the following is implied about the visit to the LouvreA. The Louvre

27、is the largest, most comprehensive art museum in the world.B. The visit was exhausting and inappropriate for small children.C. The visit encompassed diverse tastes.23.Traditional critical scholarship has considered a literary work the product of one focused mind, along with its social influences, st

28、ruggling to achieve self-expression. In such a context, the authors intended meaning, especially as it may be inferred by the circumstances surrounding his life and the work, is extremely important: the authors intention should be taken as the gold standard in determining what constitutes an accurat

29、e and valid reading of the text. A natural outgrowth of measuring the validity of readings by this standard is the rejection of those readings that do not fit what the author intended, or what the surrounding culture expected the author to intend. 24.Directions: The next questions are based on the c

30、ontent of the following passage. Read the passage and then determine the best answer choice for each question. Base your choice on what this passage states directlyor implies, not on any information you may have gained elsewhere. For each of Questions 17-20, select one answer choice unless otherwise

31、 instructed. Questions 17-19 are based on the following passage. As the works of dozens of women writers have been rescued from what E. P. Thompson calls the enormous condescen- Line sion of posterity, and considered in relation (5) to each other, the lost continent of the female tradition has risen

32、 like Atlantis from the sea of English literature. It is now becoming clear that, contrary to Mills the- ory, women have had a literature of their (10) own all along. The woman novelist, accord- ing to Vineta Colby, was really neither sin- gle nor anomalous, but she was also more than a register and

33、 spokesman for her age. She was part of a tradition that had its ori- (15) gins before her age, and has carried on through our own. Many literary historians have begun to reinterpret and revise the study of women writers. Ellen Moers sees womens literature (20) as an international movement, apart fr

34、om, but hardly subordinate to the mainstream: an undercurrent, rapid and powerful. This movement began in the late eighteenth cen- tury, was multinational, and produced some (25) of the greatest literary works of two centuries, as well as most of the lucrative pot-boilers. Patricia Meyer Spacks, in

35、The Female Imagination, finds that for readily discernible historical reasons women have characteristi- (30) cally concerned themselves with matters more or less peripheral to male concerns, or at least slightly skewed from them. The differences between traditional female preoccupations and roles an

36、d male ones make a difference in (35) female writing. Many other critics are begin- ning to agree that when we look at women writers collectively we can see an imaginative continuum, the recurrence of certain pat- terns, themes, problems, and images from generation to generation. 25.What is the aver

37、age (arithmetic mean) of 330, 360, and 390A. 360 B. 3177 C. 310 + 320 + 330D. 327 + 357 + 387 E. 329 + 359 + 38926.Sometimes an object in nature is so rare that it escapes mention in nature books. Such is the case with the delightful Kirtlands warbler. The Kirtlands warbler is a plump, yellow-breast

38、ed bird that can be found nesting almost exclusively in the upper half of Michigans Lower Peninsula. Although this bird does migrate to the Bahamas during the winter months, Michigan is its natural habitat. Unfortunately, reduced numbers have caused the Kirtlands warbler to be designated an endanger

39、ed species. The remaining Kirtlands warblers now enjoy living among the jack pine trees located in protected Michigan forests. The male warblers generally return north before the female birds. Often, they return as early as May. When they arrive, the male warblers stake out their territories and cho

40、ose a nesting area. At the completion of their own long journey from the Bahamas, the female warblers begin to collect leaves and grass to build their nests. Oddly, the Kirtlands warbler nests on the ground and not in the nearby jack pine trees themselves. During the nesting process, the male warble

41、r provides food for his mate while the female Kirtlands warbler lays four to five speckled eggs. The eggs hatch in two to three weeks and both the male and female warblers tend to their chicks.The passage implies that the author isA. disinterested in the fate of Kirtlands warblerB. a proponent of Ki

42、rtlands warblerC. a native of Michigan who travels to the BahamasD. reluctant to discuss the migratory patterns of Kirtlands warblerE. annoyed that Kirtlands warbler is not mentioned in nature books27.Since 1875, when Alexander Graham Bell first discovered how to send the human voice along wires, th

43、e telephone has been one of the worlds most utilized and essential methods of communication. The first telephone exchange in America was established in 1878 and served a total of 21 people. At that time, operators would answer a call and connect two parties by completing an electrical circuit. Littl

44、e could those operators envision that, one century later, calls would be transmitted along optical fibers and, soon after, would become totally wireless and portable. The idea of orbiting satellites picking up millions of calls and relaying them across the planet would have been unimaginable.It can

45、be inferred from the passage thatA. satellites transmit telephone callsB. early telephone users were frustrated by the technologys inefficienciesC. wireless telephones are preferable to land-based lines28.Human fascination with space began hundreds of years ago. That interest has not waned, and toda

46、y, the Hubble Telescope orbits 375 miles above Earth, working nonstop to unlock the secrets of the universe. The Hubble uses state-of-the-art instruments to provide amazing views of the universe that cannot be matched by ground-based telescopes. The reason for this is that, from the ground, we look

47、at stars and other objects in space through Earths atmosphere. Our atmosphere is full of clouds, dust, and pollution, which cause everything we see to shimmer and shake. This effect creates difficulty for scientists on the ground to make steady, accurate measurements of objects moving in space. With

48、 assistance from the Hubble Telescope, astronomers can pinpoint the location of faraway stars and galaxies, and measure the speeds and distances of astronomical objects with far greater precision. Astronomers may even one day tell us exactly when the universe began. 29.Total enrollment in higher educat
