Much has been written about the diversity of terrestrial anisms, particularly the (5) exceptionally rich life associated with tropical rainforest habitats. Relatively little has been said, however, about diversity of life in the sea even though coral reef systems are parable to rain forests in terms of richness of life. An alien exploring Earth would probably give priority to the pla39。s surface.

At least a dozen large stone houses took shape below the bluffs of Chiaco Canyon in northwest New Mexico. They were built with masonry walls more than a meter thick and adjoining apartments to acmodate dozens, even hundreds, of families. The largest, later named Pueblo Bonito (Pretty Town) by the Spanish, rose in five terraced (10) stories, contained more than 800 rooms, and could have housed a population of 1,000 or more. Besides living quarters, each pueblo included one or more kivascircular underground chambers faced with stone. They functioned as sanctuaries where the elders met to plan festivals, perform ritual dances, settle pueblo affairs, and impart (15) tribal lore to the younger generation. Some kivas were enormous. Of the 30 or so at pueblo Bonito, two measured 20 meters across. They contained niches for ceremonial objects, a central fire pit, and holes in the floor for municating with the spirits of tribal ancestors. Each pueblo represented an astonishing amount of wellanized labor. Using only (20) stone and wood tools, and without benefit of wheels or draft animals, the builders quarried ton upon ton of sandstone from the canyon walls, cut it into small blocks, hauled the blocks to the construction site, and fitted them together with mud mortar. Roof beams of pine or fir had to be carried from logging areas in the mountain forests 10 many kilometers away. Then, to connect the pueblos and to give access to the (25) surrounding tableland, the architects laid out a system of public roads with stone staircases for ascending cliff faces. In time, the roads reached out to more than 80 satellite villages within a 60kilometer radius. paragraph preceding the passage most (A) how pueblos were built (B) another Native American tribe (C) Anasazi crafts and weapons (D) Pueblo village in New Mexico is the main topic of the passage?

Some continental rocks are over 3,000 million years old, while those of the ocean flow are less than 200 million years old. The crusts and the top, solid part of the mantle, totaling about 70 to 100 kilometers in thickness, at present appear to consist of about 15 rigid plates, 7 of which are very large. These plates move over the semimolten lower mantle to produce all of the major topographical (10) features of the Earth. Active zones where intense deformation occurs are confined to the narrow, interconnecting boundaries of contact of the plates. There are three main types of zones of contact: spreading contacts where plates move apart, converging contacts where plates move towards each other, and transform contacts where plates slide past each other. New oceanic crust is formed along one or (15) more margins of each plate by material issuing from deeper layers of the Ear
