The big ranches of the West are now being cut up into small farms. The nester has come, and come to stay. Gone is the buffalo and the free grass of the open plain—even the stinging lizard, the horned frog, the centipede, the prairie dog, the rattlesnake, are fast disappearing. Save in some of the secluded valleys of southern New Mexico, the old-time round-up is no more; the trails to Kansas and to Montana have become grass-grown or lost in fields of waving grain; the maverick steer, the regal longhorn, has been supplanted by his unpoetic but more beefy and profitable Polled Angus, Durham, and Hereford cousins from across the seas. The changing and romantic West of the early days lives mainly in story and in song. The last figure to vanish is the cowboy, the animating spirit of the vanishing era. He sits his horse easily as he rides through a wide valley, enclosed by mountains, clad in the hazy purple of coming night,—with his face turned steadily down the long, long road, "the road that the sun goes down." Dauntless, reckless, without the unearthly purity of Sir Galahad though as gentle to a woman as King Arthur, he is truly a knight of the twentieth century. A vagrant puff of wind shakes a corner of the crimson handkerchief knotted loosely at his throat; the thud of his pony's feet mingling with the jingle of his spurs is borne back; and as the careless, gracious, lovable figure disappears over the divide, the breeze brings to the ears, faint and far yet cheery still, the refrain of a cowboy song.

Why does the author start the passage by listing disappearing species of the plains?

As can be inferred from the passage, the author most values __________.

Adapted from The Wind in the Willows by Kenneth Grahame (1908)

The Mole had been working very hard all the morning, spring cleaning his little home. First with brooms, then with dusters, then on ladders and steps and chairs, with a brush and a pail of whitewash, 'till he had dust in his throat and eyes, and splashes of whitewash all over his black fur, and an aching back and weary arms. Spring was moving in the air above and in the earth below and around him, penetrating even his dark and lowly little house with its spirit of divine discontent and longing. It was small wonder, then, that he suddenly flung down his brush on the floor, said "Bother!" and "O blow!" and also "Hang spring cleaning!" and bolted out of the house without even waiting to put on his coat. Something up above was calling him imperiously, and he made for the steep little tunnel which answered in his case to the gaveled carriage-drive owned by animals whose residences are nearer to the sun and air. So he scraped and scratched and scrabbled and scrooged and then he scrooged again and scrabbled and scratched and scraped, working busily with his little paws and muttering to himself, "Up we go! Up we go!" 'till at last, pop! His snout came out into the sunlight, and he found himself rolling in the warm grass of a great meadow.

"This is fine!" he said to himself. "This is better than whitewashing!" The sunshine struck hot on his fur, soft breezes caressed his heated brow, and after the seclusion of the cellarage he had lived in so long, the carol of happy birds fell on his dulled hearing almost like a shout. Jumping off all his four legs at once, in the joy of living and the delight of spring without its cleaning, he pursued his way across the meadow 'till he reached the hedge on the further side.

"Hold up!" said an elderly rabbit at the gap. "Sixpence for the privilege of passing by the private road!" He was bowled over in an instant by the impatient and contemptuous Mole, who trotted along the side of the hedge chaffing the other rabbits as they peeped hurriedly from their holes to see what the row was about. "Onion-sauce! Onion-sauce!" he remarked jeeringly, and was gone before they could think of a thoroughly satisfactory reply. Then they all started grumbling at each other. "How STUPID you are! Why didn't you tell him—" "Well, why didn't YOU say—" "You might have reminded him—" and so on, in the usual way; but, of course, it was then much too late, as is always the case.

Why does the mole say "Bother," "O blow," and "Hang spring cleaning" in the passage's first paragraph?

The Princess was still puzzled. "But I'm grown up," she said. "I don't want a mother so much now."

The King turned his flagon round and studied the other side of it.

"A mother's—er—tender hand," he said, "is—er—never——" and then the outrageous thing happened.

It was all because of a birthday present to the King of Barodia, and the present was nothing less than a pair of seven-league boots. The King being a busy man, it was a week or more before he had an opportunity of trying those boots. Meanwhile he used to talk about them at meals, and he would polish them up every night before he went to bed. When the great day came for the first trial of them to be made, he took a patronizing farewell of his wife and family, ignored the many eager noses pressed against the upper windows of the Palace, and sailed off. The motion, as perhaps you know, is a little disquieting at first, but one soon gets used to it. After that it is fascinating. He had gone some two thousand miles before he realized that there might be a difficulty about finding his way back. The difficulty proved at least as great as he had anticipated. For the rest of that day he toured backwards and forwards across the country; and it was by the merest accident that a very angry King shot in through an open pantry window in the early hours of the morning. He removed his boots and went softly to bed.

It was, of course, a lesson to him. He decided that in the future he must proceed by a recognized route, sailing lightly from landmark to landmark. Such a route his Geographers prepared for him—an early morning constitutional, of three hundred miles or so, to be taken ten times before breakfast. He gave himself a week in which to recover his nerve and then started out on the first of them.

Based on the passage, the primary purpose for the landmarks was to __________.

Adapted from The Story of Mankind by Hendrik Van Loon (1921)

During the first twenty years of his life, young Napoleon was a professional Corsican patriot—a Corsican Sinn Feiner, who hoped to deliver his beloved country from the yoke of the bitterly hated French enemy. But the French revolution had unexpectedly recognised the claims of the Corsicans and gradually Napoleon, who had received a good training at the military school of Brienne, drifted into the service of his adopted country. Although he never learned to spell French correctly or to speak it without a broad Italian accent, he became a Frenchman. In due time he came to stand as the highest expression of all French virtues. At present he is regarded as the symbol of the Gallic genius.

Napoleon was what is called a fast worker. His career does not cover more than twenty years. In that short span of time he fought more wars and gained more victories and marched more miles and conquered more square kilometers and killed more people and brought about more reforms and generally upset Europe to a greater extent than anybody (including Alexander the Great and Genghis Khan) had ever managed to do.

He was a little fellow and during the first years of his life his health was not very good. He never impressed anybody by his good looks and he remained to the end of his days very clumsy whenever he was obliged to appear at a social function. He did not enjoy a single advantage of breeding or birth or riches. For the greater part of his youth he was desperately poor and often he had to go without a meal or was obliged to make a few extra pennies in curious ways.

He gave little promise as a literary genius. When he competed for a prize offered by the Academy of Lyons, his essay was found to be next to the last and he was number 15 out of 16 candidates. But he overcame all these difficulties through his absolute and unshakable belief in his own destiny, and in his own glorious future. Ambition was the main-spring of his life. The thought of self, the worship of that capital letter "N" with which he signed all his letters, and which recurred forever in the ornaments of his hastily constructed palaces, the absolute will to make the name Napoleon the most important thing in the world next to the name of God, these desires carried Napoleon to a pinnacle of fame which no other man has ever reached.

Adapted from Seven Discourses Delivered in the Royal Academy By the President by Joshua Reynolds (1778)

All the objects which are exhibited to our view by nature, upon close examination will be found to have their blemishes and defects. The most beautiful forms have something about them like weakness, minuteness, or imperfection. But it is not every eye that perceives these blemishes. It must be an eye long used to the contemplation and comparison of these forms—and which, by a long habit of observing what any set of objects of the same kind have in common, that alone can acquire the power of discerning what each wants in particular. This long laborious comparison should be the first study of the painter who aims at the greatest style. By this means, he acquires a just idea of beautiful forms; he corrects nature by herself, her imperfect state by her more perfect. His eye being enabled to distinguish the accidental deficiencies, excrescences, and deformities of things from their general figures, he makes out an abstract idea of their forms more perfect than any one original—and what may seem a paradox, he learns to design naturally by drawing his figures unlike to any one object. This idea of the perfect state of nature, which the artist calls the ideal beauty, is the great leading principle by which works of genius are conducted. By this, Phidias acquired his fame. He wrought upon a sober principle what has so much excited the enthusiasm of the world—and by this method you, who have courage to tread the same path, may acquire equal reputation.

The author's view of nature is best summarized as __________.

Adapted from The Adventures of Tom Sawyer by Mark Twain (1876)

Within two minutes, or even less, he had forgotten all his troubles. Not because his troubles were one whit less heavy and bitter to him than a man's are to a man, but because a new and powerful interest bore them down and drove them out of his mind for the time—just as men's misfortunes are forgotten in the excitement of new enterprises. This new interest was a valued novelty in whistling, which he had just acquired, and he was suffering to practice it undisturbed. It consisted in a peculiar bird-like turn, a sort of liquid warble, produced by touching the tongue to the roof of the mouth at short intervals in the midst of the music—the reader probably remembers how to do it, if he has ever been a boy. Diligence and attention soon gave him the knack of it, and he strode down the street with his mouth full of harmony and his soul full of gratitude. He felt much as an astronomer feels who has discovered a new planet—no doubt, as far as strong, deep, unalloyed pleasure is concerned, the advantage was with the boy, not the astronomer.

The summer evenings were long. It was not dark, yet. Presently Tom checked his whistle. A stranger was before him—a boy a shade larger than himself. A newcomer of any age or either sex was an impressive curiosity in the poor little shabby village of St. Petersburg. This boy was well-dressed, too—well-dressed on a weekday. This was simply astounding. His cap was a dainty thing, his close-buttoned blue cloth roundabout was new and natty, and so were his pantaloons. He had shoes on—and it was only Friday. He even wore a necktie, a bright bit of ribbon. He had a citified air about him that ate into Tom's vitals. The more Tom stared at the splendid marvel, the higher he turned up his nose at his finery and the shabbier and shabbier his own outfit seemed to him to grow. Neither boy spoke. If one moved, the other moved—but only sidewise, in a circle; they kept face to face and eye to eye all the time.

The underlined part of the passage is most likely intended to __________.

The world described by physics is a surprisingly strange world, somewhat distant from our regular experience. Many high school students likely suspect this fact, given the difficulty that they often experience when taking physics courses. However, they are rarely instructed in the explicit difference between the world expressed by their equations and the world that they experience. Many of the concepts used in physics are related to the figures, facts, and equations that are learned in mathematics. The world is recast into a form that looks more like a geometry problem than the world as experienced in day-to-day life. All of this at first seems strange to the budding young physics student. However, after performing a number of experiments, he or she soon sees that these mathematical formulas seem to “work.” That is, these equations really do predict the outcomes of experiments in the real world, not merely in mathematical equations on paper.

Still, it is interesting to notice some examples of how much is overlooked in these kinds of mathematical models. Most obviously, there are few (if any) objects in reality that perfectly match the form and shape of a pure geometric figure. Few physical triangles are exact triangles in the manner of the shapes used in geometric problems. Likewise, motion becomes merely something to be expressed in an equation that has time as a variable. Finally, all of the physical descriptions of light waves tell us about everything except for what it is like to experience color. This last reason is perhaps the most interesting reason of all. No matter how many equations and shapes are used to describe color, none of these will have anything to do with the experience of color itself. To speak of a “rectangular surface” or an “icosahedron-like body” does not tell us anything about colors. Rectangles and icosahedrons can be any color. That is, color does not enter into their definitions at all—a red rectangle is just as much a rectangle as is a green one.

Among the large running birds are forms, like the African ostrich, in which the absence of powers of flight is largely compensated by the specialization of the legs for the purpose of rapid movement on the ground. For straightforward retreat in open country nothing could be more effective; but another kind of adaptation is required in birds like rails, which are deficient in powers of flight, and yet are able to run through thickly-growing vegetation with such rapidity as to commonly elude their enemies. This is rendered possible by the shape of their bodies, which are relatively narrow and flattened from side to side, so as to easily slip between the stems of grasses, rushes, and similar plants. Anyone who has pursued our native land-rail or corn-crake with intent to capture will have noted how extremely difficult it is even to get within sight of a bird of this sort.

Certain birds, unfortunately for themselves, have lost the power of flight without correspondingly increased powers of running, and have paid the penalty of extinction. Such an arrangement, as might be anticipated, was the result of evolution in islands devoid of any predatory ground-animals, and a classic example of it is afforded by the dodo and its allies, birds related to the pigeons. The dodo itself was a large and clumsy-looking species that at one time abounded in the island of Mauritius, which, like oceanic islands generally, possessed no native mammals, while its indigenous reptiles were only represented by lizards. The ubiquitous sailor, however, and the animals (especially swine) which he introduced, brought about the extinction of this helpless bird in less than a century after its first discovery in 1598. Its memory is now only kept green by a few contemporary drawings and descriptions, certain museum remains, and the proverb "as extinct as a dodo.” A similar fate must overtake any organism suddenly exposed to new and unfavorable conditions, if devoid of sufficient plasticity to rapidly accommodate itself to the altered environment.

The purpose of the underlined sentence is __________.
