TAILIEUCHUNG - Sat - MC Grawhill part 82

McGraw-Hill's SAT I is the only one that seems to provide just about everything students really need to prepare seriously for the new test. The biggest problem, I've found, with books like Princeton Review, Up Your Score, and REA, is that they repeat the same test-taking "tricks" that have been around for decades, and really don't help most students all that much. (Sure, it's kind of nice to have a simple rule for when to guess on a multiple choice question, but isn't it better to be able actually to solve the problems?) Princeton, Up Your Score and REA just. | 800 McGRAW-HILL S SAT 6 6 6 6 6 6 Questions 10-16 are based on the following passage. The following passage was written by a naturalist about his studies of the wildlife in the African plains particularly Serengeti National Park in Tanzania. How can so many wild animals manage to survive in the Serengeti Their migrations of Line course tell part of the story. By moving from place to place with the changing seasons they 5 do not overuse and damage the grass in any one area. But other less obvious factors also are involved. Here on the eastern plains in January it is clear that most of the animals are eating the 10 abundant grass that springs up like a well-mown lawn between low clumps of Sodom apple and indigo plants. Nearly all of them from 1 500-pound eland bulls to tiny 10-pound Thomson s gazelle calves are grazers rather 15 than browsers which feed on shrubs or the leaves of trees. Singly or in pairs long lines or little groups they move over the green pastures never remaining long in one place. Where the grass is all short as it will be when 20 it has been heavily grazed all the animals apparently eat much the same sort of grass. But where the grass is of varied lengths and toughness we can see that each animal copes differently with the available fodder. 25 The herds of zebras tend to roam in areas separate from the rest of the grazing multitude. Unlike all the other grazers on the plain they have teeth in both jaws. This enables them to deal with taller coarser grass than can 30 the other herbivores. All the rest are various species of antelope which nip off the grass between their lower incisors and toothless upper palates. Thus the zebras eat down the longer grasses to a certain level and then move on. 35 Following the zebras come the wildebeests and in better-wooded areas hartebeests. These animals eat the grass down a stage further until it is really short. They also eat new growth before it has had a chance to grow 40 tall. Then the Thomson s gazelles .
