Adapted from “Birds in Retreat” in “Animal Defences—Active Defence” in Volume Four of The Natural History of Animals: The Animal Life of the World in Its Various Aspects and Relations by James Richard Ainsworth Davis (1903)

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.

What kinds of reptiles are indigenous to Mauritius?

"Darwinism's Effect on Science" by Matthew Minerd (2014)

For much of the history of human thought, the sciences have studied subjects that seemed to be eternal and unchanging. Even the basic laws of the Nile’s flooding were investigated in the hopes of finding never-altering laws. Similarly, the scientific investigations of the ancient Near East and Greece into the regular laws of the stars ultimately looked for constant patterns. This overall pattern of scientific reasoning has left deep marks on the minds of almost all thinkers and found its apotheosis in modern physics. From the time of the early renaissance to the nineteenth century, physics represented the ultimate expression of scientific investigation for almost all thinkers. Its static laws appeared to be the unchanging principles of all motion and life on earth. By the nineteenth century, it had appeared that only a few details had to be “cleared up” before all science was basically known.

In many ways, this situation changed dramatically with the arrival of Darwinism. It would change even more dramatically in early twentieth-century physics as well. Darwin’s theories of evolution challenged many aspects of the “static” worldview. Even those who did not believe that a divine being created an unchanging world were shaken by the new vistas opened up to science by his studies. It had been a long-accepted inheritance of Western culture to believe that the species of living organisms were unchanging in nature. Though there might be many different kinds of creatures, the kinds themselves were not believed to change. The thesis of a universal morphing of types shattered this cosmology, replacing the old world-view with a totally new one. Among the things that had to change in light of Darwin’s work was the very view of science held by most people.

Which of the following gives the best example of the “static worldview” discussed in the second paragraph?

Adapted from Volume Four of The Natural History of Animals: The Animal Life of the World in Its Various Aspects and Relations by James Richard Ainsworth Davis (1903)

The examples of protective resemblance so far quoted are mostly permanent adaptations to one particular sort of surrounding. There are, however, numerous animals which possess the power of adjusting their color more or less rapidly so as to harmonize with a changing environment.

Some of the best known of these cases are found among those mammals and birds that inhabit countries more or less covered with snow during a part of the year. A good instance is afforded by the Irish or variable hare, which is chiefly found in Ireland and Scotland. In summer, this looks very much like an ordinary hare, though rather grayer in tint and smaller in size, but in winter it becomes white with the exception of the black tips to the ears. Investigations that have been made on the closely allied American hare seem to show that the phenomenon is due to the growth of new hairs of white hue. 

The common stoat is subject to similar color change in the northern parts of its range. In summer it is of a bright reddish brown color with the exception of the under parts, which are yellowish white, and the end of the tail, which is black. But in winter, the entire coat, save only the tip of the tail, becomes white, and in that condition the animal is known as an ermine. A similar example is afforded by the weasel. The seasonal change in the vegetarian Irish hare is purely of protective character, but in such an actively carnivorous creature as a stoat or weasel, it is aggressive as well, rendering the animal inconspicuous to its prey.

Why is the American hare mentioned in the passage?

Adapted from Reflections on the Revolution in France, by Edmund Burke (1790) (Project Gutenberg Edition)

It is now sixteen or seventeen years since I saw the Queen of France, then the Dauphiness, at Versailles; and surely never lighted on this orb, which she hardly seemed to touch, a more delightful vision. I saw her just above the horizon, decorating and cheering the elevated sphere she just began to move in—glittering like the morning-star, full of life and splendor and joy. Oh! what a revolution! and what an heart must I have, to contemplate without emotion that elevation and that fall! Little did I dream, when she added titles of veneration to those of enthusiastic, distant, respectful love, that she should ever be obliged to carry the sharp antidote against disgrace concealed in that bosom! little did I dream that I should have lived to see such disasters fallen upon her in a nation of gallant men, in a nation of men of honor, and of cavaliers! I thought ten thousand swords must have leaped from their scabbards to avenge even a look that threatened her with insult. But the age of chivalry is gone. That of sophisters, economists, and calculators has succeeded; and the glory of Europe is extinguished forever. Never, never more, shall we behold that generous loyalty to rank and sex, that proud submission, that dignified obedience, that subordination of the heart, which kept alive, even in servitude itself, the spirit of an exalted freedom! The unbought grace of life, the cheap defence of nations, the nurse of manly sentiment and heroic enterprise, is gone! It is gone, that sensibility of principle, that chastity of honor, which felt a stain like a wound, which inspired courage whilst it mitigated ferocity, which ennobled whatever it touched, and under which vice itself lost half its evil by losing all its grossness!

The tone of this passage can best be described as __________.

Adapted from “The Celebration of Intellect” by Ralph Waldo Emerson (1861)

I cannot consent to wander from the duties of this day into the fracas of politics. The brute noise of cannon has, I know, a most poetic echo in these days when it is an instrument of freedom and the primal sentiments of humanity. Yet it is but representative and a far-off means and servant; but here in the college we are in the presence of the constituency and the principle itself. Here is, or should be, the majesty of reason and the creative cause, and it were a compounding of all gradation and reverence to suffer the flash of swords and the boyish strife of passion and the feebleness of military strength to intrude on this sanctity and omnipotence of Intellectual Law.

Against the heroism of soldiers I set the heroism of scholars, which consists in ignoring the other. You shall not put up in your Academy the statue of Caesar or Pompey, of Nelson or Wellington, of Washington or Napoleon, of Garibaldi, but of Archimedes, of Milton, of Newton. . . .

For either science and literature is a hypocrisy, or it is not. If it be, then resign your charter to the Legislature, turn your college into barracks and warehouses, and divert the funds of your founders into the stock of a rope-walk or a candle-factory, a tan-yard or some other undoubted conveniency for the surrounding population. But if the intellectual interest be, as I hold, no hypocrisy, but the only reality, then it behooves us to enthrone it, obey it, and give it possession of us and ours; to give, among other possessions, the college into its hand casting down every idol, every pretender, every hoary lie, every dignified blunder that has crept into its administration.

Which of the following adjectives best matches the author’s opinion of “intellectual interest,” underlined in the passage's third paragraph?

Adapted from Jack London’s The Road (1907)

Barring accidents, a good hobo, with youth and agility, can hold a train down despite all the efforts of the train-crew to "ditch" him—given, of course, night-time as an essential condition. When such a hobo, under such conditions, makes up his mind that he is going to hold her down, either he does hold her down, or chance trips him up. There is no legitimate way, short of murder, whereby the train-crew can ditch him. That train-crews have not stopped short of murder is a current belief in the tramp world. Not having had that particular experience in my tramp days I cannot vouch for it personally.

But this I have heard of the "bad" roads. When a tramp has "gone underneath," on the rods, and the train is in motion, there is apparently no way of dislodging him until the train stops. The tramp, snugly ensconced inside the truck, with the four wheels and all the framework around him, has the "cinch" on the crew—or so he thinks, until some day he rides the rods on a bad road. A bad road is usually one on which a short time previously one or several trainmen have been killed by tramps. Heaven pity the tramp who is caught "underneath" on such a road—for caught he is, though the train be going sixty miles an hour.

The "shack" (brakeman) takes a coupling-pin and a length of bell-cord to the platform in front of the truck in which the tramp is riding. The shack fastens the coupling-pin to the bell- cord, drops the former down between the platforms, and pays out the latter. The coupling-pin strikes the ties between the rails, rebounds against the bottom of the car, and again strikes the ties. The shack plays it back and forth, now to this side, now to the other, lets it out a bit and hauls it in a bit, giving his weapon opportunity for every variety of impact and rebound. Every blow of that flying coupling-pin is freighted with death, and at sixty miles an hour it beats a veritable tattoo of death. The next day the remains of that tramp are gathered up along the right of way, and a line in the local paper mentions the unknown man, undoubtedly a tramp, assumably drunk, who had probably fallen asleep on the track.

What can be inferred from the passage about the author's opinion of the hobo lifestyle?
