Adapted from “Humming-Birds: As Illustrating the Luxuriance of Tropical Nature” in Tropical Nature, and Other Essays by Alfred Russel Wallace (1878)

The food of hummingbirds has been a matter of much controversy. All the early writers down to Buffon believed that they lived solely on the nectar of flowers, but since that time, every close observer of their habits maintains that they feed largely, and in some cases wholly, on insects. Azara observed them on the La Plata in winter taking insects out of the webs of spiders at a time and place where there were no flowers. Bullock, in Mexico, declares that he saw them catch small butterflies, and that he found many kinds of insects in their stomachs. Waterton made a similar statement. Hundreds and perhaps thousands of specimens have since been dissected by collecting naturalists, and in almost every instance their stomachs have been found full of insects, sometimes, but not generally, mixed with a proportion of honey. Many of them in fact may be seen catching gnats and other small insects just like fly-catchers, sitting on a dead twig over water, darting off for a time in the air, and then returning to the twig. Others come out just at dusk, and remain on the wing, now stationary, now darting about with the greatest rapidity, imitating in a limited space the evolutions of the goatsuckers, and evidently for the same end and purpose. Mr. Gosse also remarks, ” All the hummingbirds have more or less the habit, when in flight, of pausing in the air and throwing the body and tail into rapid and odd contortions. This is most observable in the Polytmus, from the effect that such motions have on the long feathers of the tail. That the object of these quick turns is the capture of insects, I am sure, having watched one thus engaged pretty close to me.”

What do Azara, Bullock, and Waterton have in common?

"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.

Consider the underlined sentence. What was the new “cosmology” that arose after Darwin’s day?

Although today high-heeled and platform shoes are often seen as footwear designed simply to make a woman seem more fashionable and appealing, they served a more utilitarian purpose during the Middle Ages. During this time, both men and women would wear detachable wooden platforms in order to protect their shoes from the weather and the grit of the streets. However, in contemporary times, heeled shoes are almost exclusively reserved for women’s footwear, primarily for aesthetic effect. Not only is the foot made to seem more petite and dainty, but the entire appearance of a woman’s body is altered.

In order to maintain her balance, a woman must tense her legs and buttocks, making them to appear more fit and firm. The back is forced in a sinuous arch, and the elongation of the legs makes a woman’s hips sway back and forth in a wider ellipsis. Whereas heels were once used for practical purposes, today they are employed purely for a pleasant aesthetic effect.

Taking this into consideration, we should evaluate why it is that women wear high heels. Is it to increase confidence in one’s sexual appeal? To attract attention from others? Or is it simply to conform to the dress expectations of society at large? The various possible motivations that might cause a woman to wear a high-heeled shoe create a great level of ambiguity as to why the shoe continues to persevere in fashion.

The author would likely agree with all of the following claims except which one?

Adapted from The Prince by Niccolo Machiavelli (1513)

Every one admits how praiseworthy it is in a prince to keep faith, and to live with integrity and not with craft. Nevertheless our experience has been that those princes who have done great things have held good faith of little account, and have known how to circumvent the intellect of men by craft, and in the end have overcome those who have relied on their word. You must know there are two ways of contesting, the one by the law, the other by force; the first method is proper to men, the second to beasts; but because the first is frequently not sufficient, it is necessary to have recourse to the second. Therefore it is necessary for a prince to understand how to avail himself of the beast and the man. This has been figuratively taught to princes by ancient writers, who describe how Achilles and many other princes of old were given to the Centaur Chiron to nurse, who brought them up in his discipline; which means solely that, as they had for a teacher one who was half beast and half man, so it is necessary for a prince to know how to make use of both natures, and that one without the other is not durable. A prince, therefore, being compelled knowingly to adopt the beast, ought to choose the fox and the lion; because the lion cannot defend himself against snares and the fox cannot defend himself against wolves. Therefore, it is necessary to be a fox to discover the snares and a lion to terrify the wolves. Those who rely simply on the lion do not understand what they are about. Therefore a wise lord cannot, nor ought he to, keep faith when such observance may be turned against him, and when the reasons that caused him to pledge it exist no longer. If men were entirely good this precept would not hold, but because they are bad, and will not keep faith with you, you too are not bound to observe it with them. Nor will there ever be wanting to a prince legitimate reasons to excuse this non-observance. Of this endless modern examples could be given, showing how many treaties and engagements have been made void and of no effect through the faithlessness of princes; and he who has known best how to employ the fox has succeeded best. But it is necessary to know well how to disguise this characteristic, and to be a great pretender and dissembler; and men are so simple, and so subject to present necessities, that he who seeks to deceive will always find someone who will allow himself to be deceived.

Which of the following is given as an example of the faithlessness of princes in the passage?

Adapted from “Introductory Remarks” in The Interpretation of Dreams by Sigmund Freud (trans. 1913)

In attempting to discuss the interpretation of dreams, I do not believe that I have overstepped the bounds of neuropathological interest. For, when investigated psychologically, the dream proves to be the first link in a chain of abnormal psychic structures whose other links—the hysterical phobia, the obsession, and the delusion—must interest the physician for practical reasons. The dream can lay no claim to a corresponding practical significance; however, its theoretical value is very great, and one who cannot explain the origin of the content of dreams will strive in vain to understand phobias, obsessive and delusional ideas, and likewise their therapeutic importance.

While this relationship makes our subject important, it is responsible also for the deficiencies in this work. The surfaces of fracture, which will be frequently discussed, correspond to many points of contact where the problem of dream formation informs more comprehensive problems of psychopathology which cannot be discussed here. These larger issues will be elaborated upon in the future.

Peculiarities in the material I have used to elucidate the interpretation of dreams have rendered this publication difficult. The work itself will demonstrate why all dreams related in scientific literature or collected by others had to remain useless for my purpose. In choosing my examples, I had to limit myself to considering my own dreams and those of my patients who were under psychoanalytic treatment. I was restrained from utilizing material derived from my patients' dreams by the fact that during their treatment, the dream processes were subjected to an undesirable complication—the intermixture of neurotic characters. On the other hand, in discussing my own dreams, I was obliged to expose more of the intimacies of my psychic life than I should like, more so than generally falls to the task of an author who is not a poet but an investigator of nature. This was painful, but unavoidable; I had to put up with the inevitable in order to demonstrate the truth of my psychological results at all. To be sure, I disguised some of my indiscretions through omissions and substitutions, though I feel that these detract from the value of the examples in which they appear. I can only express the hope that the reader of this work, putting himself in my difficult position, will show patience, and also that anyone inclined to take offense at any of the reported dreams will concede freedom of thought at least to the dream life.

In the third paragraph, what does the author tell us about the omissions and substitutions he made when discussing his own dreams in the work that follow the passage?

Since William II of Germany ascended the throne as German Emperor and King of Prussia on June 15, 1888, the eyes of Europe have been fixed on him. The press of the world delights in showing up his weak points, and the "war lord" undoubtedly has them, but, at the same time, he has qualities which are to be admired and which make him conspicuous among the rulers of Europe.

He is popular in Germany, and it is not surprising, for, in spite of being autocratic to the last degree, he is honest, courageous, ambitious, hard working, and a thorough German, being intensely patriotic. Indeed, if the people of Germany had the right to vote, they would undoubtedly choose their present ruler, for, while the virtues we have named may seem commonplace, they are not so when embodied in an emperor. One thing which places William at a disadvantage is his excessive frankness. His mistakes have largely resulted from his impulsive nature coupled with chauvinism, which is, perhaps, excusable, in a ruler.

Since the time when William was a child, he evidenced a strong desire to become acquainted with the details of the office to which his lofty birth entitled him. In the army he has worked his way up like any other officer and has a firm grasp on all the multifarious details of the military establishment of the great country. He believes in militarism, or in force, to use a more common expression, but in this he is right, for it has taken two hundred and fifty years to bring Prussia to the position it now holds, and what it has gained at the point of the sword must be retained in the same way. The immense sacrifices which the people make to support the army and navy are deemed necessary for self-preservation, and with France on one side and Russia on the other, there really seems to be ample excuse for it.

Which of these is a possible weakness that the author notes in William II’s character?
