Lake Baikal
1 Crescent-shaped Lake Baikal, in Siberia, is only the ninth largest lake in area at 385 miles (650 km) in length and 46 miles (74 km) in width, yet it is easily the largest body of fresh water in the world. It holds one-fifth of the world's total fresh water, which is more than the total of all the water in the five Great Lakes; it holds so much fresh water in spite of its less-than-impressive area because it is by far the world's deepest lake. The average depth of the lake is 1,312 feet (400 meters) below sea level, and the Olkhon Crevice, the lowest known point, is more than 5,250 feet (1,600 meters) deep.
2 Lake Baikal, which today is located near the center of the Asian peninsula, is most likely the world's oldest lake. It began forming 25 million years ago as Asia started splitting apart in a series of great faults. The Baikal Valley dropped away, eventually filling with water and creating the deepest of the world's lakes.

(C) is greater than the area of any other freshwater lake (D) is equal to the area of the five Great Lakes 3. According to paragraph 1, Lake Baikal (A) holds one-fifth of the world's water (B) holds five times the water of the Great Lakes (C) holds one-ninth of the world's water (D) holds 20 percent of the world's fresh water 4. According to paragraph 1, the Olkhon Crevice is (A) outside of Lake Baikal

Paragraph The Postage Stamp
1 The postage stamp has been around for only a relatively short period of time. The use of stamps for postage was first proposed in England in 1837, when Sir Rowland Hill published a pamphlet entitled \Its Importance and Practicability\to put forth the ideas that postal rates should not be based on the distance that a letter or package travels but should instead be based on the weight of the letter or package and that fees for postal services should be collected in advance of the delivery, rather than after, through the use of postage stamps.
2 The ideas proposed by Hill went into effect in England almost immediately, and other countries soon followed suit. The first English stamp, which featured a portrait of then Queen Victoria, was printed in 1840. This stamp, the \black,\came in sheets that needed to be separated with scissors and provided enough postage for a letter weighing 14 grams or less to any destination. In 1843, Brazil was the next nation to produce national postage stamps, and various areas in what is today Switzerland also produced postage stamps later in the same year. Postage stamps in five-and ten-cent denominations were first approved by the U.S. Congress in 1847, and by 1860 postage stamps were being issued in more than 90 governmental jurisdictions worldwide. 6. According to paragraph 1, postage stamps were first suggested (A) in the first half of the eighteenth century (B) in the second half of the eighteenth century
400-080-6358 www.zhan.com (C) in the first half of the nineteenth century (D) in the second half of the nineteenth century
7. It is indicated in paragraph 1 that Sir Rowland Hill believed that postage fees (A) should be paid by the sender (B) should be related to distance
(C) should have nothing to do with how heavy a package is (D) should be collected after the package is delivered
8. What is stated in paragraph 2 about the first English postage stamp? (A) It was designed by Queen Victoria. (B) It contained a drawing of a black penny. (C) It was produced in sheets of 14 stamps. (D) It could be used to send a lightweight letter.

paragraph The Clovis Culture
1 Archeologists have found sites all over North America that contain similar tools dating from a period about 12,000 years ago. The culture that developed these tools has been named Clovis after the site near Clovis, New Mexico, where the first tools of this sort were discovered in 1932. The tools are quite sophisticated and are unlike any tools that have been found in the Old World. 2 In the years since the first tools of this sort were discovered in New Mexico, archeologists
400-080-6358 www.zhan.com have discovered Clovis tools in areas ranging from Mexico to Montana in the United States and Nova Scotia in Canada. All of the Clovis finds date from approximately the same period, a fact which suggests that the Clovis spread rapidly throughout the North American continent.
3 From the evidence that has been discovered, archeologists have concluded that the Clovis were a mobile culture. They traveled in groups of 40 to 50 individuals, migrating seasonally and returning to the same hunting camps each year. Their population increased rapidly as they spread out over the continent, and they were quite possibly motivated to develop their sophisticated hunting tools to feed their rapidly expanding populace. 11. What is stated in paragraph 1 about Clovis tools? (A) They date from around 10,000 B.C. (B) They have been in use for 12,000 years. (C) They have been found at only one location.
(D) They were discovered by archeologists hundreds of years ago. 12. According to paragraph 1, the town of Clovis (A) is in Mexico (B) was founded in 1932
(C) is where all members of the Clovis culture lived
(D) is where the first remnants of an ancient culture were found
13. It is indicated in paragraph 1 that the tools found near Clovis, New Mexico, were (A) very rudimentary
(B) similar to others found prior to 1932 (C) rather advanced
(D) similar to some found in Africa and Europe
14. According to paragraph 2, what conclusion have archeologists drawn from the Clovis finds? (A) That the Clovis tended to remain in one place (B) That the Clovis expanded relatively quickly (C) That the Clovis lived throughout the world (D) That the Clovis were a seafaring culture
