Model Test 12

　　At the bottom of the world lies a mighty continent still wrapped in the Ice Ag e and, until recent times, unknown to man. It is a 1 land mass crisscrossed by mountain 2 whose extent and elevation are still uncertain. Much of the 3 is a complete blank on our maps. A 1,00-mile stretch of the coastline has never been 4 by any ship. Man has 5 , on foot, less than one per cent of its area.

　　Antarctica differs 6 from the Arctic regions. The Arctic is an ocean, 7 with drifting packed ice and surrounded by the land masses of Europe, Asia, and North America. The Antarctic is a continent nearly as 8 as Europe and Australia combined, centered roughly 9 the South Pole and 10 by the most unobstructed water areas of the world - the Atlantic, Pacific, and Indian Oceans.

　　The continental ice 11 is more than two miles high at its center; thus, the air over the Antarctic is 12 more refrigerated than it is over the Arctic regions. This 13 air cascades off the land with such 14 that it makes the near by seas the stormiest in the world and renders 15 those regions whose counterparts at the opposite end of the 16 a re inhabited. Thus, more than a million persons 17 within 2,000 miles of the North Pole in an area that 18 most of Alaska, Siberia, and Scandinavia - a region 19 in forest and mining industries. Except for a handful of weather, within the same 20 of the South Pole there is not a single tree, industry, or settlement.
