Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:

Since water is the basis of life, composing the greater part of the tissues of all living things, the crucial problem of desert animals is to survive in a world where sources of flowing water are rare. And since man’s inexorable necessity is to absorb large quantities of water at frequent intervals, he can scarcely comprehend that many creatures of the desert pass their entire lives without a single drop. Uncompromising as it is, the dessert has not eliminated life but only those forms unable to withstand its desiccating effects. No moist-skinned, water–loving animals can exist there. Few large animals are found: the giants of the North America desert are the deer, the coyote, and the bobcat. Since desert country is open, it holds more swift–footed, running, and leaping creatures than the tangled forest. Its populations are largely nocturnal, silent, filled with reticence, and ruled by stealth. Yet they are not emaciated. Having adapted to their austere environment, they are as healthy as animals anywhere in the world. The secret of their adjustment lies in a combination of behavior and physiology. None could survive if, like mad dogs and Englishmen, they went out in the midday sun; many would die in a matter of minutes. So most of them pass the burning hours asleep in cool, humid burrows underneath the ground, emerging to hunt only by night. The surface of the sun–baked desert averages around 150 degrees, but 18 inches down the temperature is only 60 degrees.

Baseball evolved from a number of different ball-and stick games (paddle ball, trap ball, one-old-cat, rounders, and town ball) originating in England. As early as the American Revolution, it was noted that troops played “baseball” in their free time. In 1845 Alexander Cartwright formalized the New York Knickerbockers version of the game: a diamond shaped infield, with bases ninety feet apart, three strikers – you’re – out, batter out on a caught ball, three outs per inning, a nine man team. “The New York Game” spread rapidly, replacing earlier localized forms. From its beginnings, baseball was seen as a way of satisfying the recreational needs of an increasingly urban – industrial society. At its inception it was it was played by and for gentlemen. A club might consist of 40 members. The president would appoint two captains who would choose teams from among the members. Games were played on Monday and Thursday afternoons, with the losers often providing a lavish evening’s entertainments for the winners. During the 1850 - 70 period the game was changing, however, with increasing commercialism (charging admission), under – the – table payments to exceptional to players, and gambling on the outcome of games. By 1868 it was said that a club would have their regular professional ten, an amateur first - nine, and their "muffins" (the gently duffers who once ran the game). Beginning with the first openly all – salaried team (Cincinnati’s Red Stocking Club) in 1869, the 1870 - 1890 period saw the complete professionalization of baseball, including formation of the National Association of Professional baseball players in 1871. The National League of Professional Baseball Clubs was formed in 1876, run by business-minded invertors in joint-stock company clubs. The 1880s has been called Major League Baseball’s “Golden Age”. Profits soared, player’s salaries rose somewhat, a season of 84 games became one of 132, a weekly periodical “The sporting News” came into being, wooden stadiums with double-deck stands replaced open fields, and the standard refreshment became hot dogs, soda pop and peanuts. In 1900 the Western League based in the growing cities of the Mid-west proclaimed itself the American League.

Question 15: The word “inception” in line 8 is closest in meaning to _____         

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:

Cooperation is the common endeavor of two more people to perform a task of reach a jointly cherished goad. Like competition and conflict, there are different forms of cooperation, based on group organization and attitudes. In the first form, known as primary cooperation, group and individuals fuse. The group contains nearly all of each individual’s life. The rewards of the group’s work are share with each number. There is an interlocking identity of individual, group, and task performed. Means and goals become one, for cooperation itself is valued. While primary cooperation is most often characteristic of preliterate societies, secondary cooperation is characteristic of many modern societies. In secondary cooperation, individuals devote only part of their lives to the group. Cooperation itself is not a value. Most member of the group fell loyalty, but the welfare of the group is not the first consideration. Members perform tasks so that they can separately enjoy the fruits of their cooperation in the form of salary, prestige, or power. Business offices and professional athletic teams are example of secondary cooperation. In the third type, called tertiary cooperation or accommodation, latent conflict underlies the share work. The attitudes of the cooperation parties are purely opportunistic; the organization is loose and fragile. Accommodation involve common means cease to aid achieve antagonistic goals; it breaks when the common means cease to aid each party in reaching its goals. This is not, strictly speaking, cooperation at all, and hence the somewhat contradictory term antagonistic cooperation is sometimes used for this relationship.
