A Short History of Recent Zoos, by Will Floyd

Throughout the twentieth century, zoos underwent large-scale transformations. Before World War I, zoos were small parts of larger municipal parks, and featured sparse cages with little room for their inhabitants. This model held sway until mid-century, with many zoos struggling to remain open during the Great Depression and World War II. The successful zoos survived through making themselves cheap family entertainment. In the 1960s, zoos began to change in drastic ways. With the growing strength of environmental- and animal-rights movements, the public clamored for more naturalistic and spacious environments in which the animals could live.

The most emblematic of these transformations was the development of the Los Angeles Zoo. In 1966, the cramped and antiquated zoo used grants from the city government to move to a brand-new facility. Although the zoo moved just two miles away, the new location was exponentially bigger, and it featured fresh landscapes that resembled the animals’ natural habitats, instead of dilapidated cages. As the Los Angeles Zoo developed, it was able to work on preservation and conservation efforts for endangered species. New educational programs also became key elements of the Zoo’s mission. Now the old Zoo’s cages stand as ruins and reminders of what past generations saw when they visited years ago.

The phrase "this model" in the passage refers to __________.

Adapted from "The Writing of Essays" in Certain Personal Matters by H.G. Wells (1901)

The art of the essayist is so simple, so entirely free from canons of criticism, and withal so delightful, that one must needs wonder why all men are not essayists. Perhaps people do not know how easy it is. Or perhaps beginners are misled. Rightly taught it may be learnt in a brief ten minutes or so, what art there is in it. And all the rest is as easy as wandering among woodlands on a bright morning in the spring.

Then sit you down if you would join us, taking paper, pens, and ink; and mark this, your pen is a matter of vital moment. For every pen writes its own sort of essay, and pencils also after their kind. The ink perhaps may have its influence too, and the paper; but paramount is the pen. This, indeed, is the fundamental secret of essay-writing. Wed any man to his proper pen, and the delights of composition and the birth of an essay are assured. Only many of us wander through the earth and never meet with her—futile and lonely men.

And, of all pens, your quill for essays that are literature. There is a subtle informality, a delightful easiness, perhaps even a faint immorality essentially literary, about the quill. The quill is rich in suggestion and quotation. There are quills that would quote you Montaigne and Horace in the hands of a trades-union delegate. And those quirky, idle noises this pen makes are delightful, and would break your easy fluency with wit. All the classical essayists wrote with a quill, and Addison used the most expensive kind the Government purchased. And the beginning of the inferior essay was the dawn of the cheap steel pen.

The phrase "mark this" as Wells uses it in the first sentence of the second paragraph most likely means __________.

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 does the author mean in using the underlined phrase “kept green”?

"Cacti" by Ami Dave (2013)

Cacti are plants suited to the desert and we must keep this factor in mind always when growing ornamental cacti in our gardens, for it helps in the survival of the plant. For example, a cactus should never be watered over its body as it will start to rot. This is because it is covered with a waxy coating which prevents water loss through evaporation. When one waters the cactus over its body, the waxy coating is washed away and the plant begins to rot. The amount of water that you must supply to the cactus is very much dependent upon the season and upon the climate of the place. During the summer season one should water cacti every four days whereas in the rainy season once every fifteen days is quite enough.

Cacti need a minimum of two and a half hours of sunlight per day. However they should not be kept all day in the sun because they may wrinkle in too much of bright sunlight. Unlike other plants cacti produce carbon dioxide during the day and oxygen during the night. Hence, they are ideal plants to be kept in bedrooms to freshen up the air at night.

If the cactus plant is to thrive and prosper, the size of the pot in which it is grown has to be carefully monitored. The pot should always be a little smaller than the plant itself because it is only when the plant has to struggle to survive that it will thrive. If the pot is too spacious the struggle element is removed and the chances are that the cactus will die. Cacti are like human beings. When they suffer they will grow. Similarly if a cactus shows no signs of growth, stop the watering. It should be resumed only when the plant resumes growth.

The substrata of a cactus pot is ideally composed of pieces of broken bricks at the bottom, charcoal above it, then coarse sand and pebbles above it. Leaf mould is the best manure.

Grafting of cacti is very simple. A very small piece of the cactus plant should be stuck with cellotape to the plant that needs grafting. The smaller the piece the easier it is to graft. To reproduce cacti, one has to simply cut off a piece of the cactus, allow it to dry for a few days and then just place it over the cacti substrate. It will automatically develop roots.

To differentiate between cacti and other plants that look like cacti is very easy. All cacti have fine hair at the base of each thorn. The so-called thorns are in fact highly modified leaves which prevent loss of water through transpiration. If one ever gets pricked by cacti thorns, one should take cellotape, place it over the area where the thorns have penetrated the skin and then peel it off. All the thorns will get stuck to the cellotape and will be removed.

If the author were to add the underlined sentences, "Cacti are like human beings. When they suffer they will grow," to the third paragraph, what would these lines mean in context?

"Interpreting the Copernican Revolution" by Matthew Minerd (2014)

The expressions of one discipline can often alter the way that other subjects understand themselves. Among such cases are numbered the investigations of Nicolaus Copernicus. Copernicus is best known for his views concerning heliocentrism, a view which eventually obliterated many aspects of the ancient/medieval worldview, at least from the standpoint of physical science. It had always been the natural view of mankind that the earth stood at the center of the universe, a fixed point in reference to the rest of the visible bodies. The sun, stars, and planets all rotated around the earth.

With time, this viewpoint became one of the major reference points for modern life. It provided a provocative image that was used—and often abused—by many people for various purposes. For those who wished to weaken the control of religion on mankind, it was said that the heliocentric outlook proved man’s insignificance. In contrast with earlier geocentrism, heliocentrism was said to show that man is not the center of the universe. He is merely one small being in the midst of a large cosmos. However, others wished to use the “Copernican Revolution” in a very different manner. These thinkers wanted to show that there was another “recentering” that had to happen. Once upon a time, we talked about the world. Now, however, it was necessary to talk of man as the central reference point. Just as the solar system was “centered” on the sun, so too should the sciences be centered on the human person.

However, both of these approaches are fraught with problems. Those who wished to undermine the religious mindset rather misunderstood the former outlook on the solar system. The earlier geocentric mindset did not believe that the earth was the most important body in the heavens. Instead, many ancient and medieval thinkers believed that the highest “sphere” above the earth was the most important being in the physical universe. Likewise, the so-called “Copernican Revolution” in physics was different from the one applied to the human person. Copernicus’ revolution showed that the human point of view was not the center, whereas the later forms of “Copernican revolution” wished to show just the opposite.

Of course, there are many complexities in the history of such important changes in scientific outlook. Nevertheless, it is fascinating to see the wide-reaching effects of such discoveries, even when they have numerous, ambiguous effects.

How was the underlined view about geocentrism incorrect?

A PLEA FOR A LONG WALK

Sir—In these days of increasing rapid artificial locomotion, may I be permitted to say a word in favor of a very worthy and valuable old friend of mine, Mr. Long-Walk?

I am afraid that this good gentleman is in danger of getting neglected, if not forgotten. We live in days of water trips and land trips, excursions by sea, road, and rail—bicycles and tricycles, tram cars and motor cars, hansom cabs and ugly cabs; but in my humble opinion good honest walking exercise for health beats all other kinds of locomotion into a cocked hat. In rapid traveling all the finer nerves, senses, and vessels are "rush" and unduly excited, but in walking every particle of the human frame, and even the moral faculties, are evenly and naturally brought into exercise. It is the best discipline and physical mental tonic in the world. Limbs, body, muscles, lungs, chest, heart, digestion, breathing, are healthily brought into normal operation, while. especially in the long distance walk, the exercise of patience, perseverance, industry, energy, perception, and reflection—and, indeed, all the senses and moral faculties—are elevated and cultivated healthfully and naturally. Many never know the beauty of it because they never go far enough: exercise and hard work should never be relinquished at any age or by either sex. Heart disease, faintness, and sudden death, and even crime, are far more due to the absence of wholesome normal exercise and taste than to anything else, to enervating luxuries rather than to hill climbing.

I usually give myself a holiday on a birthday, and as I lately reached my 63rd I determined to give myself a day with my old friend Mr. Long-Walk, and decided to tramp to the city of Wells and back for my birthday holiday—a distance of about forty-two miles. Fortune favors the brave, and, thanks to a mosquito that pitched on my nose and was just commencing operations, I woke very early in the morning. It is an ill wind that blows no one any good. Mosquitoes are early birds, but I stole a march on them. But to my journey.

I started at about 5 A.M., and proceeding via Dundry and Chow Stoke, reached Wells soon after 10 A.M. After attending the cathedral, I pursued my walk homeward by a different route, via Chewton Mendip, Farrington, Temple Cloud, Clutton, and Pensford.

To make a walk successful, mind and body should be free of burden. I never carry a stick on a long walk, but prefer to be perfectly free, giving Nature’s balancing poles—the pendulum arms—complete swing and absolute liberty. Walking exercises, together with a well-educated palate, are the greatest physicians in the world: no disease can withstand them. I returned from my forty-two miles tramp with birthday honors and reward. I had no headache on the following morning, but was up early in good form, fresh and ready for work. Forty-two miles may be too strong a dose for many, but I cannot too strongly recommend for a day’s companionship the society of my old and well-tried friend, Mr. Long-Walk.

Faithfully yours,

T. Thatcher

44 College Green, Bristol.

Adapted from "The Eulogy of the Dog" by George Graham Vest (1870)

The best friend a man has in this world may turn against him and become his enemy. His son or daughter whom he has reared with loving care may prove ungrateful. Those who are nearest and dearest to us, those whom we trust with our happiness and our good name, may become traitors to their faith. The money that a man has, he may lose. It flies away from him, perhaps when he needs it the most. A man’s reputation may be sacrificed in a moment of ill-considered action. The people who are prone to fall on their knees to do us honor when success is with us may be the first to throw the stone of malice when failure settles its cloud upon our heads. The one absolutely unselfish friend that a man can have in this selfish world, the one that never deserts him and the one that never proves ungrateful or treacherous is his dog.

Gentlemen of the jury, a man’s dog stands by him in prosperity and in poverty, in health and in sickness. He will sleep on the cold ground, where the wintry winds blow and the snow drives fiercely, if only he can be near his master’s side. He will kiss the hand that has no food to offer, he will lick the wounds and sores that come in encounter with the roughness of the world. He guards the sleep of his pauper master as if he were a prince.

When all other friends desert, he remains. When riches take wings and reputation falls to pieces, he is as constant in his love as the sun in its journey through the heavens. If fortune drives the master forth an outcast into the world, friendless and homeless, the faithful dog asks no higher privilege than that of accompanying him, to guard him against danger, to fight against his enemies. And when the last scene of all comes, and death takes his master in its embrace and his body is laid in the cold ground, no matter if all other friends pursue their way, there by his graveside will the noble dog be found, his head between his paws, his eyes sad but open, in alert watchfulness, faithful and true, even unto death.

The expression “riches take wings” could be paraphrased as __________.

"Commentaries" by Matthew Minerd (2013)

The idea of a commentary is not anywhere as simple as most people think. To the popular imagination, the commentator makes a few observations based on a text, not going far beyond its contents. This standard opinion completely misses the various types of commentaries that can be written. Indeed, even the notion of “literal commentary” is itself so variegated that it is incorrect to imagine that such “literal” work is merely a slavish repetition of an original text.

Some literal commentaries truly are “literal,” that is, based on the letters and words of the text. Such philological studies investigate the language structures and meanings of a text. The interpretation of the text proceeds based on these linguistic investigations. Often, this process will note the types of rhetoric being used, the dialects utilized, and any odd language structures that might imply something with regard to the text’s meaning. All of these methods remain very concerned with the “letter of the text” in a very direct manner.

Indeed, even the Medieval commentaries on Aristotle’s works could be considered “literal,” though they do differ from such linguistic approaches. Men like Thomas Aquinas would very carefully read Aristotle’s text, giving what was called a divisio textus for every section of the text in question. This “division of the text” sought to provide a succinct but correct outline of the text in question so that its literal meaning might be more easily noticed. Certainly, the commentary that followed this divisio textus did express some aspects of Aquinas’ own thought. However, he (like other literal commentators of this type) would attempt to remain as close to the literal meaning of the text as possible, always using the divisio textus as a guide for understanding the structure of the original author’s thought.

What is the difference between the type of commentary mentioned in the second paragraph and that which is mentioned in the third paragraph?

Adapted from The Struggles of Charles Goodyear by George C. Towle (1916)

Never did any man work harder, suffer more keenly, or remain more steadfast to one great purpose of life, than did Charles Goodyear. The story of his life—for the most part mournful—teems with touching interest. No inventor ever struggled against greater or more often returning obstacles, or against repeated failures more overwhelming. Goodyear is often compared, as a martyr and hero of invention, to Bernard Palissy the potter. He is sometimes called "the Palissy of the nineteenth century." But his sufferings were more various, more bitter, and more long enduring than ever were even those of Palissy; while the result of his long, unceasing labors was infinitely more precious to the world. For if Palissy restored the art of enameling so as to produce beautiful works of art, Goodyear perfected a substance which gives comfort and secures health to millions of human beings.

It was by accident at last that he hit upon the secret of how to make India-rubber durable. He was talking one day to several visitors, and in his ardor making rapid gestures, when a piece of rubber that he was holding in his hand accidentally hit against a hot stove. To his amazement, instead of melting, the gum remained stiff and charred, like leather. He again applied great heat to a piece of rubber, and then nailed it outside the door, where it was very cold. The next morning he found that it was perfectly flexible; and this was the discovery which led to that successful invention which he had struggled through so many years to perfect. The main value of the discovery lay in this, that while the gum would dissolve in a moderate heat, it both remained hard and continued to be flexible when submitted to an extreme heat. This came to be known as the "vulcanization" of India-rubber.

Goodyear was terribly afraid that he should die before he could make the world perceive the great uses to which his discovery might be applied. What he was toiling for was neither fame nor fortune, but only to confer a vast benefit on his fellow men.

At last, after infinite struggles, the absorbing purpose of his life was attained. India-rubber was introduced under his patents, and soon proved to have all the value he had, in his wildest moments, claimed for it. Success thus crowned his noble efforts, which had continued unceasingly through ten years of self-imposed privation. India-rubber was now seen to be capable of being adapted to at least five hundred uses. It could be made "as pliable as kid, tougher than oxhide, as elastic as whalebone, or as rigid as flint." But, as too often happens, his great discovery enriched neither Goodyear nor his family. It soon gave employment to sixty thousand artisans, and annually produced articles in this country alone worth eight millions of dollars.

Happily the later years of the noble, self-denying inventor were spent at least free from the grinding penury and privations of his years of uncertainty and toil. He died in 1860 in his sixtieth year, happy in the thought of the magnificent boon he had given to mankind.

Why does the author think that comparisons between Goodyear and Palissy are irrelevant?
