Unformatted text preview: ls supports the coastal hypothesis by providing evidence that ○humans were changing their hunting techniques to adapt to coastal rather than inland environments ○animals had migrated from the inland to the coasts, an indication that a midcontinental ice­free corridor was actually implausible ○humans probably would have been able to find enough resources along the coastal corridor ○the continental shelf was still exposed by lower sea levels during the period when the southward migration of people began 10. The word inhospitable in the passage is closest in meaning to ○not familiar ○not suitable ○not dangerous ○not reachable 11. According to paragraph 5, the most recent geologic research provides support for a first colonization of America dating as far back as ○16,000 years ago ○14,000 years ago ○12,500 years ago ○10,000 years ago Paragraph 6: The coastal hypothesis suggests an economy based on marine mammal hunting, saltwater fishing gathering, and the use of watercraft. Because of the barrier of ice to the east, the Pacific Ocean to the west, and populated areas to the north, there may have been a greater impetus for people to move in a southerly direction. 267 Mail@liuwenyong.com 在在在在在在 www.liuwenyong.com 在在在在在在在在在在在在在在在,在在在在在在在在在在 12. The word impetus in the passage is closest in meaning to ○chance ○protection ○possibility ○incentive Paragraph 1: It has long been accepted that the Americas were colonized by a migration of peoples from Asia, slowly traveling across a land bridge called Beringia (now the Bering Strait between northeastern Asia and Alaska) during the last Ice Age. ■The first water craft theory about the migration was that around 11,000­12,000 years ago there was an ice­free corridor stretching from eastern Beringia to the areas of North America south of the great northern glaciers. It was the midcontinental corridor between two massive ice sheets­the Laurentide to the west­that enabled the southward migration. ■But belief in this ice­free corridor began to crumble when paleoecologist Glen MacDonald demonstrated that some of the most important radiocarbon dates used to support the existence of an ice­ free corridor were incorrect. ■He persuasively argued that such an ice­free corridor did not exist until much later, when the continental ice began its final retreat. ■ 13. Look at the four squares [■] that indicate where the following sentence could be added to the passage. Moreover, other evidence suggests that even if an ice­free corridor did exist, it would have lacked the resources needed for human colonization. Where could the sentence best fit? 14. Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some answer choices do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points. Recent evidence favors a rival to the...
