The rowboat Fox, of the port of New York, manned by George Harbo, thirty-one years of age, captain of a merchantman, and Frank Samuelson, twenty-six years of age, left New York for Havre on the sixth of June. Ten days later the boat was met by the German transatlantic steamer Fürst Bismarck proceeding from Cherbourg to New York. On the eighth, ninth and tenth of July, the Fox was cast by a tempest upon the reefs of Newfoundland. The two men jumped into the sea, and thanks to the watertight compartments provided with air chambers fore and aft, it was possible for them to right the boat; but the unfortunates lost their provisions and their supply of drinking water. On the fifteenth they met the Norwegian three-masted vessel Cito, which supplied them with food and water. The captains of the vessels met with signed the log book and testified that the boat had neither sail nor rudder. The Fox reached the Scilly Islands on the first of August, having at this date been on the ocean fifty-five days. It arrived at Havre on the seventh of August.

Cost what it might, the men were bent upon reaching this port in order to gain the reward promised by Mr. Fox, of the Police Gazette. Thanks to the wind and a favorable current, they made one hundred and twenty-five miles in twenty-four hours. One slept three hours while the other rowed. Their skins and faces were tumefied by the wind, salt water, and sun; the skin of their hands was renewed three times; their legs were weakened; and they were worn out.

Why did the two men want to row across the Atlantic?

Adapted from Early European History by Hutton Webster (1917)

The Phoenicians were a Syrian people whose country was a narrow stretch of coast, about one hundred and twenty miles in length, seldom more than twelve miles in width, between the Lebanon Mountains and the sea. This tiny land could not support a large population. As the Phoenicians increased in numbers, they were obliged to betake themselves to the sea. The Lebanon cedars furnished soft, white wood for shipbuilding, and the deeply indented coast offered excellent harbors. Thus, the Phoenicians became preeminent sailors. Their great cities, Sidon and Tyre, established colonies throughout the Mediterranean and had an extensive commerce with every region of the known world.

Why could the Phoenician land not support a large population?

"The Holy Roman Empire" by Daniel Morrison (2014)

The Holy Roman Empire was somewhat unique among the various organized states of Middle and Early Modern Europe in that the Emperor was chosen by a group of electors. This is in stark contrast to the strict hereditary nature of English or French succession, where the position of monarch was handed down from the outgoing ruler to his closest legitimate heir, usually a son. In the Holy Roman Empire, the Emperor was chosen by seven electors, which in theory might seem to give the Empire a sort of early democratic flavor. However, in practice, only two or three families were ever able to draw on sufficient personal wealth to stand for election. Of these, the Luxembourgs and the Hapsburgs are most well known. The Hapsburgs were so successful that they were able to maintain their “elected” position for almost four centuries, and the Luxembourgs somehow still have a small country named after their family almost seven hundred years after their fall from dominance.

Why were the Hapsburg and Luxembourg families able to stand for election?

"The Units of Ancient Warfare" by Daniel Morrison (2014)

The armies of the ancient world were generally composed of three distinct units who faced off against each other in a gigantic game of rock-paper-scissors. These were the infantry, cavalry, and slingers. The heavily armored but slow-moving infantry were able to fend off the cavalry with their long pikes, but were sitting ducks for the fast moving slingers who carried only a sling and a bag of small rocks. The slingers in turn were great at taking down infantry as they could out-maneuver them and never get bogged down in hand-to-hand combat, but were easily decimated by the rapidly advancing cavalry.

In this manner the history of warfare progressed for several thousand years. The slingers were replaced by archers, and then by heavily artillery; the cavalry constantly advanced in tactical awareness and arms; and the infantry progressed from swordsmen, to pikemen, to riflemen. Next time you are playing rock-paper-scissors to decide who gets the last slice of pizza, don’t forget that you are channeling your inner Scipio Africanus.

Why did slingers maintain an advantage over infantry?

Adapted from The Swiss Family Robinson by Johann David Wyss (1879 Kingston ed.)

Thus talking, we pushed on until we came to a pleasant grove which stretched down to the water's edge. Here, we halted to rest, seating ourselves under a large tree, by a rivulet that murmured and splashed along its pebbly bed into the great ocean before us. A thousand gaily-plumaged birds flew twittering above us, and Fritz and I gazed up at them.

My son suddenly started up.

"A monkey," he exclaimed. “I am nearly sure I saw a monkey."

As he spoke, he sprang round to the other side of the tree, and in doing so, stumbled over a small round object. He handed it to me, remarking as he did so that it was a round bird's nest, of which he had often heard. "You may have done so," said I, laughing, "but this is a coconut."

We split open the nut, but, to our disgust, found the kernel dry and uneatable.

"Hullo," cried Fritz, "I always thought a coconut was full of delicious sweet liquid, like almond milk."

"So it is," I replied, "when young and fresh, but as it ripens the milk becomes congealed, and in course of time is solidified into a kernel. This kernel then dries as you see here, but when the nut falls on favorable soil, the germ within the kernel swells until it bursts through the shell, and, taking root, springs up a new tree."

"I do not understand," said Fritz, "how the little germ manages to get through this great thick shell, which is not like an almond or hazelnut shell, which is divided down the middle already."

"Nature provides for all things," I answered, taking up the pieces. " Look here, do you see these three round holes near the stalk? It is through them that the germ obtains egress. Now let us find a good nut if we can."

As coconuts must be overripe before they fall naturally from the tree, it was not without difficulty that we obtained one in which the kernel was not dried up. When we succeeded, however, we were so refreshed by the fruit that we could defer eating until later in the day, and so spare our stock of provisions.

The narrator says that there are holes in coconut shells so that __________.

Adapted from The Call of the Wild by Jack London (1903)

Buck did not read the newspapers, or he would have known that trouble was brewing, not alone for himself, but for every tide-water dog, strong of muscle and with warm, long hair, from Puget Sound to San Diego. Because men, groping in the Arctic darkness, had found a yellow metal, and because steamship and transportation companies were booming the find, thousands of men were rushing into the Northland. These men wanted dogs, and the dogs they wanted were heavy dogs, with strong muscles by which to toil, and furry coats to protect them from the frost.

Buck lived at a big house in the sun-kissed Santa Clara Valley. Judge Miller's place, it was called. It stood back from the road, half hidden among the trees, through which glimpses could be caught of the wide cool veranda that ran around its four sides. The house was approached by graveled driveways which wound about through wide-spreading lawns and under the interlacing boughs of tall poplars. At the rear things were on even a more spacious scale than at the front. There were great stables, where a dozen grooms and boys held forth, rows of vine-clad servants' cottages, an endless and orderly array of outhouses, long grape arbors, green pastures, orchards, and berry patches. Then there was the pumping plant for the artesian well, and the big cement tank where Judge Miller's boys took their morning plunge and kept cool in the hot afternoon.

And over this great demesne Buck ruled. Here he was born, and here he had lived the four years of his life. It was true, there were other dogs, There could not but be other dogs on so vast a place, but they did not count. They came and went, resided in the populous kennels, or lived obscurely in the recesses of the house after the fashion of Toots, the Japanese pug, or Ysabel, the Mexican hairless—strange creatures that rarely put nose out of doors or set foot to ground. On the other hand, there were the fox terriers, a score of them at least, who yelped at Toots and Ysabel looking out of the windows at them, protected by a legion of housemaids armed with brooms and mops.

Which of the following groups of adjectives best describes the location in which Buck lives?

Adapted from "The Bat, the Birds, and the Beasts" by Aesop (trans. Jacobs 1909)

A great conflict was about to take place between the Birds and the Beasts. When the two armies were gathered together, the Bat hesitated which to join. The Birds that passed his perch said "Come with us," but he said to them, "I am a Beast."

Later on, some Beasts who were passing underneath him looked up and said "Come with us," but he said, "I am a Bird." Luckily at the last moment peace was made, and no battle took place, so the Bat came to the Birds and wished to join in the celebrations, but they all turned against him and he had to fly away. He then went to the Beasts, but soon had to run away, or else they would have torn him to pieces. "Ah," said the Bat, "I see now: he that is neither one thing nor the other has no friends."

Why do you think the birds and the beasts refuse to be friends with the bat at the end of the story?

Adapted from Through the Looking Glass by Lewis Carroll (1871)

One thing was certain, that the white kitten had had nothing to do with it—it was the black kitten's fault entirely. For the white kitten had been having its face washed by the old cat for the last quarter of an hour (and bearing it pretty well, considering); so you see that it COULDN'T have had any hand in the mischief.

The way Dinah washed her children's faces was this: first she held the poor thing down by its ear with one paw, and then with the other paw she rubbed its face all over, the wrong way, beginning at the nose: and just now, as I said, she was hard at work on the white kitten, which was lying quite still and trying to purr—no doubt feeling that it was all meant for its good.

But the black kitten had been finished with earlier in the afternoon, and so, while Alice was sitting curled up in a corner of the great arm-chair, half talking to herself and half asleep, the kitten had been having a grand game of romps with the ball of worsted Alice had been trying to wind up, and had been rolling it up and down till it had all come undone again; and there it was, spread over the hearth-rug, all knots and tangles, with the kitten running after its own tail in the middle.

'Oh, you wicked little thing!' cried Alice, catching up the kitten, and giving it a little kiss to make it understand that it was in disgrace. 'Really, Dinah ought to have taught you better manners! You OUGHT, Dinah, you know you ought!' she added, looking reproachfully at the old cat, and speaking in as cross a voice as she could manage—and then she scrambled back into the arm-chair, taking the kitten and the worsted with her, and began winding up the ball again. But she didn't get on very fast, as she was talking all the time, sometimes to the kitten, and sometimes to herself. Kitty sat very demurely on her knee, pretending to watch the progress of the winding, and now and then putting out one paw and gently touching the ball, as if it would be glad to help, if it might.

Alice didn’t stop the black kitten from unwinding the ball because __________.

Adapted from The Fight at the Pass of Thermopylæ by Charlotte M. Yonge (1876)

The troops sent for this purpose were from different cities, and amounted to about 4,000 who were to keep the pass against two millions. The leader of them was Leonidas, who had newly become one of the two kings of Sparta, the city that above all in Greece trained its sons to be hardy soldiers, dreading death infinitely less than shame. Leonidas had already made up his mind that the expedition would probably be his death, perhaps because a prophecy had been given at the Temple at Delphi that Sparta should be saved by the death of one of her kings of the race of Hercules. He was allowed by law to take with him 300 men, and these he chose most carefully, not merely for their strength and valor, but selecting those who had sons, so that no family might be altogether destroyed. These Spartans, with their helots or slaves, made up his own share of the numbers, but all the army was under his generalship. It is even said that the 300 celebrated their own funeral rites before they set out lest they should be deprived of them by the enemy, since, as we have already seen, it was the Greek belief that the spirits of the dead found no rest till their obsequies had been performed. Such preparations did not daunt the spirits of Leonidas and his men, and his wife, Gorgo, not a woman to be faint-hearted or hold him back. Long before, when she was a very little girl, a word of hers had saved her father from listening to a traitorous message from the King of Persia; and every Spartan lady was bred up to be able to say to those she best loved that they must come home from battle "with the shield or carried upon it."

Why did the Spartans celebrate their funeral rites before they departed?

Adapted from "The Sing-Song of Old Man Kangaroo" in Just So Stories by Rudyard Kipling (1902)

Not always was the Kangaroo as now we do behold him, but a Different Animal with four short legs. He was grey and he was woolly, and his pride was inordinate: he danced on an outcrop in the middle of Australia, and he went to the Little God Nqa.

He went to Nqa at six before breakfast, saying, “Make me different from all other animals by five this afternoon.”

Up jumped Nqa from his seat on the sand flat and shouted, “Go away!”

He was grey and he was woolly, and his pride was inordinate: he danced on a rock-ledge in the middle of Australia, and he went to the Middle God Nquing.

He went to Nquing at eight after breakfast, saying, “Make me different from all other animals; make me, also, wonderfully popular by five this afternoon.”

Up jumped Nquing from his burrow in the spinifex and shouted, “Go away!”

He was grey and he was woolly, and his pride was inordinate: he danced on a sandbank in the middle of Australia, and he went to the Big God Nqong.

He went to Nqong at ten before dinner-time, saying, “Make me different from all other animals; make me popular and wonderfully run after by five this afternoon.”

Up jumped Nqong from his bath in the salt-pan and shouted, “Yes, I will!”

Nqong called Dingo—Yellow-Dog Dingo—always hungry, dusty in the sunshine, and showed him Kangaroo. Nqong said, “Dingo! Wake up, Dingo! Do you see that gentleman dancing on an ashpit? He wants to be popular and very truly run after. Dingo, make him SO!”

Up jumped Dingo—Yellow-Dog Dingo—and said, "What, that cat-rabbit?"

Off ran Dingo—Yellow-Dog Dingo—always hungry, grinning like a coal-scuttle—ran after Kangaroo.

Off went the proud Kangaroo on his four little legs like a bunny.

This, O Beloved of mine, ends the first part of the tale!

He ran through the desert; he ran through the mountains; he ran through the salt-pans; he ran through the reed-beds; he ran through the blue gums; he ran through the spinifex; he ran till his front legs ached.

He had to!

Still ran Dingo—Yellow-Dog Dingo—always hungry, grinning like a rat-trap, never getting nearer, never getting farther—ran after Kangaroo.

He had to!

Still ran Kangaroo—Old Man Kangaroo. He ran through the ti-trees; he ran through the mulga; he ran through the long grass; he ran through the short grass; he ran through the Tropics of Capricorn and Cancer; he ran till his hind legs ached.

He had to!

Still ran Dingo—Yellow-Dog Dingo—hungrier and hungrier, grinning like a horse-collar, never getting nearer, never getting farther; and they came to the Wollgong River.

Now, there wasn't any bridge, and there wasn't any ferry-boat, and Kangaroo didn't know how to get over; so he stood on his legs and hopped.

He had to!

Which of these answers explains why the Dingo chased the Kangaroo?

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.

Based on the passage, which of the following can we infer would be the best reason for animals living in variable arctic environments to change their fur color?

Adapted from Cassell’s Natural History by Francis Martin Duncan (1913)

The penguins are a group of birds inhabiting the southern ocean, for the most part passing their lives in the icy waters of the Antarctic seas. Like the ratitae, penguins have lost the power of flight, but the wings are modified into swimming organs and the birds lead an aquatic existence and are scarcely seen on land except in the breeding season. They are curious-looking creatures that appear to have no legs, as the limbs are encased in the skin of the body and the large flat feet are set so far back that the birds waddle along on land in an upright position in a very ridiculous manner, carrying their long narrow flippers held out as if they were arms. When swimming, penguins use their wings as paddles while the feet are used for steering.

Penguins are usually gregarious—in the sea, they swim together in schools, and on land, assemble in great numbers in their rookeries. They are very methodical in their ways, and on leaving the water, the birds always follow well-defined tracks leading to the rookeries, marching with much solemnity one behind the other in soldierly order.

The largest species of penguins are the king penguin and the emperor penguin, the former being found in Kerguelen Land, the Falklands, and other southern islands, and the latter in Victoria Land and on the pack ice of the Antarctic seas. As they are unaccustomed from the isolation of their haunts to being hunted and persecuted by man, emperor penguins are remarkably fearless, and Antarctic explorers invading their territory have found themselves objects of curiosity rather than fear to the strange birds who followed them about as if they were much astonished at their appearance.

The emperor penguin lays but a single egg and breeds during the intense cold and darkness of the Antarctic winter. To prevent contact with the frozen snow, the bird places its egg upon its flat webbed feet and crouches down upon it so that it is well covered with the feathers. In spite of this precaution, many eggs do not hatch and the mortality amongst the young chicks is very great.

According to the passage, why are emperor penguins so bold in approaching Antarctic explorers?

Adapted from "America the Old World" by L. Agassiz in Wonders of Earth, Sea, and Sky (1902, ed. Edward Singleton Holden)

There is, perhaps, no part of the world where the early geological periods can be studied with so much ease and precision as in the United States. Along their northern borders, between Canada and the United States, there runs the low line of hills known as the Laurentian Hills. Insignificant in height, nowhere rising more than fifteen hundred or two thousand feet above the level of the sea, these are nevertheless some of the first mountains that broke the uniform level of the earth's surface and lifted themselves above the waters. Their low stature, as compared with that of other more lofty mountain ranges, is in accordance with an invariable rule, by which the relative age of mountains may be estimated. The oldest mountains are the lowest, while the younger and more recent ones tower above their elders, and are usually more torn and dislocated also. So it is known the Alps, Rockies, and Himalayas are considerably younger than the Appalachian mountains.

How do we know that the Appalachians are older than the Alps?

Adapted from "Bats" by W. S. Dallas in A Book of Natural History (1902, ed. David Starr Jordan)

Like the owls, with which they share the dominion of the evening air, the bats have a perfectly noiseless flight; their activity is chiefly during the twilight, although some species are later, and in fact seem to keep up throughout the whole night. As they rest during the day, concealed usually in the most inaccessible places they can find, and are seen only upon the wing, their power of flight is their most striking peculiarity in the popular mind, and it is perhaps no great wonder that by many people, both in ancient and modern times, they have been regarded as birds. Nevertheless, their hairy bodies and leathery wings are so unlike anything that we ordinarily understand as pertaining to a bird, that opinion was apparently always divided, as to the true nature of these creatures—“a mouse with wings,” as Goldsmith called it once, according to James Boswell, is certainly a curious animal, and very difficult to classify so long as the would-be systematist has no particularly definite ideas to guide him. The likeness of the bat to a winged mouse has made itself felt in the name given to the creature in many languages, such as the “chauvesouris” of the French and the “flitter-mouse” of some parts of England, the latter being reproduced almost literally in German, Dutch, and Swedish, while the Danes called the bat a “flogenmues,” which has about the same meaning.

Why does the author believe many people have long regarded bats as birds?

Adapted from Anecdotes of the Habits and Instincts of Animals by Mrs. R. Lee (1852)

The Carnivora are divided by naturalists into three groups, the characters of which are taken from their feet and manner of walking. Bears rank among the Plantigrada, or those which put the whole of their feet firmly upon the ground when they walk. They are occasionally cunning and ferocious, but often evince good humor and a great love of fun. In their wild state, they are solitary the greater part of their lives. They climb trees with great facility; live in caverns, holes, and hollow trees; and in cold countries, retire to some sequestered spot during the winter, where they remain concealed and bring forth their young. Some say they are torpid, but this cannot be, for the female bears come from their retreats with cubs that have lived upon them, and it is not likely that they can have reared them and remained without food; they are, however, often very lean and wasted, and the absorption of their generally large portion of fat contributes to their nourishment. The story that they live by sucking their paws is, as may be supposed, a fable; when well-fed they always lick their paws, very often accompanying the action with a peculiar sort of mumbling noise. There are a few which will never eat flesh, and all are able to do without it. They are, generally speaking, large, clumsy, and awkward, possessing large claws for digging, and often walk on their hind feet, a facility afforded them by the peculiar formation of their thigh bone. They do not often attack in the first instance, unless impelled by hunger or danger; they are, however, formidable opponents when excited. In former times, there were few parts of the globe in which they were not to be found, but, like other wild animals, they have disappeared before the advance of man. Still they are found in certain spots from the northern regions of the world to the burning climes of Africa, Asia, and America. The latest date of their appearance in Great Britain was in Scotland during the year 1057.

What reason does the author give for the disappearance of bears around the world?

Adapted from Cowboy Songs and Other Frontier Ballads by John A. Lomax (1910)

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?

"Addictions" by Matthew Minerd (2013)

Addictions come in many forms, often quite hidden from those who should be aware of them. It is helpful to be aware of how hidden these obsessive behaviors can be. Often, they appear to be harmless, but this appearance is deceptive. Perhaps several examples can assist in increasing the reader’s awareness of these potentially problematic habits.

A very simple example of such an apparently innocuous addiction is the addiction that many people have to a beverage like coffee. While not as destructive as an addiction to alcohol, an extreme need for caffeine often covers a need for more sleep or an overzealous desire to be completely energetic at every waking moment. Also, a great deal of caffeine can potentially do damage to one’s heart due to the stress caused by its stimulating effects.

Another example of a seemingly harmless addiction can be found in the case of people who are addicted to work. It is very tempting to praise such obsessive behavior, as it provides many benefits for others and even for the one doing the work. The advancement of a career certainly seems beneficial and often allows for great personal and financial fulfillment. Nevertheless, constant work often hides some sadness, insecurity, or fear that should be confronted by the person who slaves away without cessation. Likewise, over time, such continuous work often can be greatly destructive of important personal relationships.

Of course, many more examples could be brought forth, for one can obsess over almost anything. Still, even these two simple examples should make clear to the reader that it is possible for there to be apparently harmless—indeed, seemingly helpful—life practices that in reality can pose a potential harm to one’s physical or mental well-being.
