D Section Three: Reading Comprehension Questions 18 Prehistoric mammoths have been preserved in the famous tar pits of Rancho La Brea (Brea is the Spanish word for tar) in what now the heart of Los Angeles, California. These tar pits have been known for centuries and were formerly mined for their natural Line asphalt, a black or brown petroleumlike substance. Thousands of tons were extracted (5) before 1875, when undertaken that established the significance of this remarkable site. excavations were undertaken that established the significance of this remarkable site The tar pits were found to contain the remains of scores of species of animals from the last 30,000 years of the Ice Age. Since then, over 100 tons of fossils, million from vertebrates, million from (10) invertebrates, have been recovered, often in densely concentrated tangled masses. The creatures found range form insects and birds to giant ground sloth’s, but a total of 17 proboscides (animal with a proboscis or long nose) including mastodons and Columbian mammoths have been recovered, most of them from Pit 9, the deepest bonebearing deposit, which was excavated in 1914. Most of the fossils date to between (15) 40,000 and 10,000 years ago. The asphalt at La Brea seeps to the surface, especially in the summer, and forms shallow puddles that would often have been concealed by leaves and dust. Unwary animals would bee trapped on these thin sheets of liquid asphalt, which are extremely sticky in warm weather. Stuck, the unfortunate beasts would die of exhaustion and (20) hunger or fall prey to predators that often also became stuck. As the animals decayed, more scavengers would be attracted and caught in their turn. 7 Carnivores greatly outnumber herbivores in the collection: for every large herbivore, there is one sabertooth cat, a coyote, and four wolves. The fact that some bones are heavily weathered shows that some bodies remained above the surface for weeks or (25) months. Bacteria in the asphalt would have consumed some of the tissues other than bones, and the asphalt itself would dissolve what was left, at the same time impregnating and beautifully preserving the saturated bones, rendering then dark brown and shiny. aspect of the La Brea tar pits does the passage mainly discuss?

(D) To define the term ―scavengers‖ Questions 919 The principal difference between urban growth in Europe and in the American colonies was the slow evolution of cities in the former and their rapid growth in the latter. In Europe they grew over a period of centuries from town economies to their present] (Line) urban structure. In North America, they started as wilderness munities and developed (5) to mature urbanism’s in little more than a century. In the early colonial day in North America, small cities sprang up along the Atlantic Coastline, mostly in what are now New America, small cities sprang up along the Atlantic United States and in the lower Saint Lawrence valley in Canada. This was natural because these areas were nearest England and France, particularly England, from which (10 ) most capital goods (assets such as equipment) and many consumer goods were imported Merchandising establishments were, accordingly, advantageously located in port cities from which goods could be readily distributed to interior settlements. Here, too, were the favored locations for processing raw materials prior to export. Boston, Philadelphia, New York, Montreal, and other cities flourished, and, as the colonies grew, these cities 8 (15) increased in importance. This was less true in the colonial South, where life centered around large farms, known as plantations, rather than around towns, as was the case in the areas further north along the Atlantic coastline. The local isolation and the economic selfsufficiency
