Example Question #1 : Analyzing Argumentative Claims, Bias, And Support In Social Science / History Passages

Adapted from The Condition of the Working-Class in England in 1844 by Friedrich Engels (ed. 1892, trans. Wischnewetzky)

The order of our investigation of the different sections of the proletariat follows naturally from the foregoing history of its rise. The first proletarians were connected with manufacture, were engendered by it, and accordingly, those employed in manufacture, in the working up of raw materials, will first claim our attention. The production of raw materials and of fuel for manufacture attained importance only in consequence of the industrial change, and engendered a new proletariat, the coal and metal miners. Then, in the third place, manufacture influenced agriculture, and in the fourth, the condition of Ireland; and the fractions of the proletariat belonging to each, will find their place accordingly. We shall find, too, that the factory hands are most enlightened as to their own interests, the miners somewhat less so, the agricultural laborers scarcely at all. We shall find the same order again among the industrial workers, and shall see how the factory hands, eldest children of the industrial revolution, have from the beginning to the present day formed the nucleus of the Labour Movement, and how the others have joined this movement just in proportion as their handicraft has been invaded by the progress of machinery. We shall thus learn from the example which England offers, from the equal pace which the Labour Movement has kept with the movement of industrial development, the historical significance of manufacture.

Since, however, at the present moment, pretty much the whole industrial proletariat is involved in the movement, and the condition of the separate sections has much in common, because they all are industrial, we shall have first to examine the condition of the industrial proletariat as a whole, in order later to notice more particularly each separate division with its own peculiarities.

It has been already suggested that manufacture centralizes property in the hands of the few. It requires large capital with which to erect the colossal establishments that ruin the petty trading bourgeoisie and with which to press into its service the forces of Nature, so driving the hand labour of the independent workman out of the market. The division of labour, the application of water and especially steam, and the application of machinery, are the three great levers with which manufacture, since the middle of the last century, has been busy putting the world out of joint. Manufacture, on a small scale, created the middle-class; on a large scale, it created the working-class, and raised the elect of the middle-class to the throne, but only to overthrow them the more surely when the time comes. Meanwhile, it is an undeniable and easily explained fact that the numerous, petty middle-class of the “good old times” has been annihilated by manufacture, and resolved into rich capitalists on the one hand and poor workers on the other.

The centralizing tendency of manufacture does not, however, stop here. Population becomes centralized just as capital does; and, very naturally, since the human being, the worker, is regarded in manufacture simply as a piece of capital for the use of which the manufacturer pays interest under the name of wages. A manufacturing establishment requires many workers employed together in a single building, living near each other and forming a village of themselves in the case of a good-sized factory. They have needs for satisfying which other people are necessary; handicraftsmen, shoemakers, tailors, bakers, carpenters, stonemasons, settle at hand. The inhabitants of the village, especially the younger generation, accustom themselves to factory work, grow skillful in it, and when the first mill can no longer employ them all, wages fall, and the immigration of fresh manufacturers is the consequence. So the village grows into a small town, and the small town into a large one. The greater the town, the greater its advantages. It offers roads, railroads, canals; the choice of skilled labour increases constantly, new establishments can be built more cheaply because of the competition among builders and machinists who are at hand, than in remote country districts, whither timber, machinery, builders, and operatives must be brought; it offers a market to which buyers crowd, and direct communication with the markets supplying raw material or demanding finished goods. Hence the marvelously rapid growth of the great manufacturing towns. The country, on the other hand, has the advantage that wages are usually lower than in town, and so town and country are in constant competition; and, if the advantage is on the side of the town to-day, wages sink so low in the country to-morrow, that new investments are most profitably made there. But the centralizing tendency of manufacture continues in full force, and every new factory built in the country bears in it the germ of a manufacturing town. If it were possible for this mad rush of manufacture to go on at this rate for another century, every manufacturing district of England would be one great manufacturing town, and Manchester and Liverpool would meet at Warrington or Newton; for in commerce, too, this centralization of the population works in precisely the same way, and hence it is that one or two great harbors, such as Hull and Liverpool, Bristol, and London, monopolize almost the whole maritime commerce of Great Britain.

In the third paragraph, the information about the centralization of property ownership serves ultimately to __________.

Possible Answers:

condemn the creation of a class of homeless people

postulate that manufacture leaves no middle class

argue that there is a need for more buildings in the modern manufacturing culture

praise the modern ability for people to own multiple houses

persuade the reader that three classes of people have emerged from the manufacturing boom

Correct answer:

postulate that manufacture leaves no middle class

Explanation:

The end of the third paragraph shows us what the author believes is the ultimate result of the centralization of property ownership: “[the] petty middle-class of the 'good old times' has been annihilated by manufacture, and resolved into rich capitalists on the one hand and poor workers on the other.” The middle classes, in the author's opinion, have been destroyed and replaced by the wealthy and the impoverished.

Example Question #193 : Social Science / History Passages

Adapted from "Federalist No. 46. The Influence of the State and Federal Governments Compared" by James Madison in The Federalist Papers by Alexander Hamilton, James Madison, and John Jay (1788)

Many considerations, besides those suggested on a former occasion, seem to place it beyond doubt that the first and most natural attachment of the people will be to the governments of their respective states. Into the administration of these a greater number of individuals will expect to rise. From the gift of these a greater number of offices and emoluments will flow. By the superintending care of these, all the more domestic and personal interests of the people will be regulated and provided for. With the affairs of these, the people will be more familiarly and minutely conversant. And with the members of these, will a greater proportion of the people have the ties of personal acquaintance and friendship, and of family and party attachments; on the side of these, therefore, the popular bias may well be expected most strongly to incline.

Experience speaks the same language in this case. The federal administration, though hitherto very defective in comparison with what may be hoped under a better system, had, during the war, and particularly whilst the independent fund of paper emissions was in credit, an activity and importance as great as it can well have in any future circumstances whatever. It was engaged, too, in a course of measures which had for their object the protection of everything that was dear and the acquisition of everything that could be desirable to the people at large. It was, nevertheless, invariably found, after the transient enthusiasm for the early Congresses was over, that the attention and attachment of the people were turned anew to their own particular governments; that the federal council was at no time the idol of popular favor; and that opposition to proposed enlargements of its powers and importance was the side usually taken by the men who wished to build their political consequence on the prepossessions of their fellow-citizens.

Which of the following is NOT a result the author mentions as likely to arise from people being more attached to their state governments than to their federal government?

Possible Answers:

More individuals will work for state governments.

More people will have friends and relatives who work in the state governments.

State taxes will increase in order to pay for expanding state governments.

More state governmental offices will be created.

Citizens will be more aware of the actions of their state governments.

Correct answer:

State taxes will increase in order to pay for expanding state governments.

Explanation:

While it is logical that state taxes may very well rise if all of the other effects of citizens' preference for state government take place, the author never mentions taxes in the paragraph. All of the other answer choices are mentioned in the first paragraph of the passage as potential effects caused by the relative popularity of state governments.

Example Question #1 : Purpose And Effect Of Phrases Or Sentences In Social Science / History Passages

Adapted from The Crisis by Carrie Chapman Catt (1916)

The war will soon end and the armies will return to their native lands. To many a family, the men will never come back. The husband, who returns to many a wife, will eat no bread the rest of his life save of her earning. What then, will happen after the war? Will the widows left with families to support cheerfully leave their well-paid posts for those commanding lower wages? Not without protest! Will the wives who now must support crippled husbands give up their skilled work and take up the occupations which were open to them before the war? Will they resignedly say: "The woman who has a healthy husband who can earn for her, has a right to tea and raisin cake, but the woman who earns for herself and a husband who has given his all to his country, must be content with tasteless bread?" Not without protest! On the contrary, the economic axiom, denied and evaded for centuries, will be blazoned on every factory, counting house and shop: "Equal pay for equal work"; and common justice will slowly, but surely enforce that law. The European woman has risen. She may not realize it yet, but the woman "doormat" in every land has unconsciously become a "door-jamb." She will have become accustomed to her new dignity by the time the men come home. She will wonder how she ever could have been content lying across the threshold now that she discovers the upright jamb gives so much broader and more normal a vision of things. The men returning may find the new order a bit queer but everything else will be strangely unfamiliar too, and they will soon grow accustomed to all the changes together. The "jamb" will never descend into a "doormat" again.

The male and female anti-suffragists of all lands will puff and blow at the economic change which will come to the women of Europe. They will declare it to be contrary to Nature and to God's plan and that somebody ought to do something about it. Suffragists will accept the change as the inevitable outcome of an unprecedented world's cataclysm over which no human agency had any control and will trust in God to adjust the altered circumstances to the eternal evolution of human society. They will remember that in the long run, all things work together for good, for progress and for human weal.

The economic change is bound to bring political liberty. From every land, there comes the expressed belief that the war will be followed by a mighty, oncoming wave of democracy for it is now well known that the conflict has been one of governments, of kings and czars, kaisers and emperors — not of peoples. The nations involved have nearly all declared that they are fighting to make an end of wars. New and higher ideals of governments and of the rights of the people under them, have grown enormously during the past two years. Another tide of political liberty, similar to that of 1848, but of a thousand-fold greater momentum, is rising from battlefield and hospital, from camp and munitions factory, from home and church which, great men of many lands, tell us, is destined to sweep over the world. On the continent, the women say, "It is certain that the vote will come to men and women after the war, perhaps not immediately but soon. In Great Britain, which was the storm centre of the suffrage movement for some years before the war, hundreds of bitter, active opponents have confessed their conversion on account of the war services of women. Already, three great provinces of Canada, Manitoba, Alberta, and Saskatchewan, have given universal suffrage to their women in sheer generous appreciation of their war work.

The example of the Canadian provinces who have recently granted women the right to vote serves primarily to highlight the __________ of the suffrage movement.

Possible Answers:

imperceptibility

immorality 

apathy 

futility 

inevitability 

Correct answer:

inevitability 

Explanation:

In the preceding sentences the author states how opponents to female suffrage in Great Britain have had their minds changed by the contribution of women to the British war effort. The author intimates that as the war goes on and women’s role in wartime society becomes stronger and more defined the trend towards acceptance will inevitably continue. To provide evidence to support this inevitability the author highlights the three provinces of Canada that have already enabled women to vote.

Example Question #21 : Understanding Causes And Effects In Social Science Or History Passages

Adapted from On Women’s Right to Vote (1872) by Susan B. Anthony

Friends and fellow citizens, I stand before you tonight under indictment for the alleged crime of having voted at the last presidential election, without having a lawful right to vote. It shall be my work this evening to prove to you that in thus voting, I not only committed no crime, but, instead, simply exercised my citizen's rights, guaranteed to me and all United States citizens by the National Constitution, beyond the power of any state to deny.

The preamble of the Federal Constitution says: "We, the people of the United States, in order to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity, do ordain and establish this Constitution for the United States of America." It was we, the people; not we, the white male citizens; nor yet we, the male citizens; but we, the whole people, who formed the Union. And we formed it, not to give the blessings of liberty, but to secure them; not to the half of ourselves and the half of our posterity, but to the whole people—women as well as men. And it is a downright mockery to talk to women of their enjoyment of the blessings of liberty while they are denied the use of the only means of securing them provided by this democratic-republican government—the ballot.

What does the author of this passage believe is the only means of securing the “blessings of liberty” (line 16)?

Possible Answers:

Peaceful protest

Organized exhortations of politicians

Voting in elections

Adhering to the Cult of Domesticity

Rewriting the United States Constitution

Correct answer:

Voting in elections

Explanation:

This question can be answered simply by reading the concluding sentence to the passage. The author states that the “blessings of liberty” can only be secured at “the ballot.” This is an idiomatic way of expressing that liberty is secured through voting in elections. Although the author does mention the United States Constitution, it is primarily used to quote the authority of a respected source and to support the author’s argument.

Example Question #3 : Social Science / History Passages

Adapted from “Letting Go,” part of A Southern Woman’s Story by Phoebe Yates Pember (1879)

 Instructing him to find the doctor immediately and hastily getting on some clothing I hurried to the scene, for Fisher was an especial favorite. He was quite a young man, of about twenty years of age, who had been wounded ten months previously, very severely, high up on the leg near the hip and who by dint of hard nursing; good food and plenty of stimulant had been given a fair chance for recovery. The bones of the broken leg had slipped together, then lapped, and nature anxious as she always is to help herself had thrown a ligature across, uniting the severed parts; but after some time the side curved out, and the wounded leg was many inches shorter than its fellow. He had remained through all his trials, stout, fresh and hearty, interesting in appearance, and so gentle-mannered and uncomplaining that we all loved him. Supported on his crutches he had walked up and down his ward for the first time since he was wounded, and seemed almost restored. That same night he turned over and uttered an exclamation of pain.

Following the nurse to his bed, and turning down the covering, a small jet of blood spurted up. The sharp edge of the splintered bone must have severed an artery. I instantly put my finger on the little orifice and awaited the surgeon. He soon came--took a long look and shook his head. The explanation was easy; the artery was imbedded in the fleshy part of the thigh and could not be taken up. No earthly power could save him. 

The hardest trial of my duty was laid upon me; the necessity of telling a man in the prime of life, and fullness of strength that there was no hope for him. It was done at last, and the verdict received patiently and courageously, some directions given by which his mother would be informed of his death, and then he turned his questioning eyes upon my face.

"How long can I live?"

"Only as long as I keep my finger upon this artery." A pause ensued. God alone knew what thoughts hurried through that heart and brain, called so unexpectedly from all earthly hopes and ties. He broke the silence at last.

"You can let go--"

But I could not. Not if my own life had trembled in the balance. Hot tears rushed to my eyes, a surging sound to my ears, and a deathly coldness to my lips. The pang of obeying him was spared me, and for the first and last time during the trials that surrounded me for four years, I fainted away. No words can do justice to the uncomplaining nature of the Southern soldier. Whether it arose from resignation or merely passive submission, yet when shown in the aggregate in a hospital, it was sublime. Day after day, whether lying wasted by disease or burning up with fever, torn with wounds or sinking from debility, a groan was seldom heard. The wounded wards would be noisily gay with singing, laughing, fighting battles o'er and o'er again, and playfully chaffing each other by decrying the troops from different States, each man applauding his own.

The description of nature as “anxious” serves to __________ nature.

Possible Answers:

elevate

condemn 

dramatize 

demonize 

personify 

Correct answer:

personify 

Explanation:

By affixing a human characteristic to nature the author is personifying nature. To personify means to ascribe human qualities to something abstract. To condemn means to consider someone guilty; demonize means to compare someone to a real or abstract evil; elevate means to raise something or someone up; dramatize is make more dramatic.

The revelation that this incident was the only time the author fainted during the war serves to __________.

Possible Answers:

minimize the effect of the story on the reader

demonstrate the weakness of the author

dramatize the strength of the Southern soldier

highlight the impact of the experience on the author

show how war is usually more manageable than is usually perceived

Correct answer:

highlight the impact of the experience on the author

Explanation:

By revealing that the experience with the young Southern soldier was the only instance during the war in which the author fainted the author is trying to highlight the impact that the experience had on her. The author states: “Hot tears rushed to my eyes, a surging sound to my ears, and a deathly coldness to my lips. The pang of obeying him was spared me, and for the first and last time during the trials that surrounded me for four years, I fainted away.” It also has the additional effect of intensifying the emotional response of the reader.

Example Question #501 : Sat Critical Reading

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.

The author argues that understanding the content of dreams is necessary for __________.

Possible Answers:

understanding the rest of the work from which this passage is drawn

accurately diagnosing a number of psychological conditions in patients

comprehending the therapeutic importance of dreams

understanding delusional ideas

understanding why he had difficulty choosing dreams to discuss in the work that follows

Correct answer:

understanding delusional ideas

Explanation:

At the end of the first paragraph, the author states, “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.” Thus, the correct answer is that understanding the content of dreams is necessary for understanding delusional ideas.

Example Question #21 : Understanding Causes And Effects In Social Science Or History Passages

Adapted from Common Sense by Thomas Paine (1776)

Society in every state is a blessing, but government even in its best state is but a necessary evil, in its worst state an intolerable one; for when we suffer, or are exposed to the same miseries heightened by reflecting that we furnish the means by which we suffer. Government, like dress, is the badge of lost innocence; the palaces of kings are built on the ruins of the bowers of paradise. For were the impulses of conscience clear, uniform, and irresistibly obeyed, man would need no other lawgiver; but that not being the case, he finds it necessary to surrender up a part of his property to furnish means for the protection of the rest; and this he is induced to do by the same prudence that in every other case advises him out of two evils to choose the least. WHEREFORE, security being the true design and end of government, it unanswerably follows that whatever FORM thereof appears most likely to ensure it to us, with the least expense and greatest benefit, is preferable to all others. 

In order to gain a clear and just idea of the design and end of government, let us suppose a small number of persons settled in some sequestered part of the Earth, unconnected with the rest; they will then represent the first peopling of any country, or of the world. In this state of natural liberty, society will be their first thought. A thousand motives will excite them thereto, the strength of one man is so unequal to his wants, and his mind so unfitted for perpetual solitude, that he is soon obliged to seek assistance and relief of another, who in his turn requires the same. Four or five united would be able to raise a tolerable dwelling in the midst of a wilderness, but ONE man might labor out the common period of life without accomplishing any thing; when he had felled his timber he could not remove it, nor erect it after it was removed; hunger in the mean time would urge him from his work, and every different want call him a different way.

What reason does the author give to support his opinion that government is “in its best state is but a necessary evil, in its worst state an intolerable one”?

Possible Answers:

You’re not allowed to get your money back if you pay for the government and then don’t agree with it. 

The government is not at all beholden to the people and functions as an independent entity.

People who live in the wilderness can get along without a government.

Whether or not we like the government, we provide the money and resources that keeps it running.

The government is an intolerable evil when taxes are high, and a necessary evil when taxes are more reasonable.

Correct answer:

Whether or not we like the government, we provide the money and resources that keeps it running.

Explanation:

The author states that government is in ““in its best state is but a necessary evil, in its worst state an intolerable one” in the first sentence of the passage. He continues, “for when we suffer, or are exposed to the same miseries heightened by reflecting that we furnish the means by which we suffer.” You can tell by the way he uses the word “for” that it is functioning like the word “because.” This means that the information following the “for” is the information the author is using to back up his initial assertion. To paraphrase that information, the author is saying that the government is in its best state a necessary evil because whether we like it or not, we provide the money and resources  that keeps it running. 

Example Question #501 : Sat Critical Reading

Adapted from The Wealth of Nations by Adam Smith (1776)

The greatest improvements in the productive powers of labor, and the greater part of the skill, dexterity, and judgment with which it is anywhere directed or applied, seem to have been the effects of the division of labor. The effects of the division of labor, in the general business of society, will be more easily understood by considering in what manner it operates in some particular manufactures. It is commonly supposed to be carried furthest in some very trifling ones; not perhaps that it really is carried further in them than in others of more importance, but in those trifling manufactures that are destined to supply the small wants of but a small number of people, the whole number of workmen must necessarily be small; and those employed in every different branch of the work can often be collected into the same workhouse, and placed at once under the view of the spectator.

In those great manufactures, on the contrary, which are destined to supply the great wants of the great body of the people, every different branch of the work employs so great a number of workmen that it is impossible to collect them all into the same workhouse. We can seldom see more, at one time, than those employed in one single branch. Though in such manufactures, therefore, the work may really be divided into a much greater number of parts, than in those of a more trifling nature, the division is not near so obvious, and has accordingly been much less observed.

To take an example, therefore, from a very trifling manufacture, but one in which the division of labor has been very often taken notice of: the trade of a pin-maker. A workman not educated to this business (which the division of labor has rendered a distinct trade), nor acquainted with the use of the machinery employed in it (to the invention of which the same division of labor has probably given occasion), could scarce, perhaps, with his utmost industry, make one pin in a day, and certainly could not make twenty. But in the way in which this business is now carried on, not only the whole work is a peculiar trade, but it is divided into a number of branches, of which the greater part are likewise peculiar trades. One man draws out the wire; another straights it; a third cuts it; a fourth points it; a fifth grinds it at the top for receiving the head; to make the head requires two or three distinct operations; to put it on is a peculiar business; to whiten the pins is another; it is even a trade by itself to put them into the paper; and the important business of making a pin is, in this manner, divided into about eighteen distinct operations, which, in some manufactories, are all performed by distinct hands, though in others the same man will sometimes perform two or three of them.

In every other art and manufacture, the effects of the division of labour are similar to what they are in this very trifling one; though, in many of them, the labour can neither be so much subdivided, nor reduced to so great a simplicity of operation. The division of labour, however, so far as it can be introduced, occasions, in every art, a proportionable increase of the productive powers of labour. The separation of different trades and employments from one another, seems to have taken place, in consequence of this advantage.

Which of the following does the author identify as the likely cause of the invention of the specific machinery involved in manufacturing pins?

Possible Answers:

the relative usefulness of pins.

the number of people involved in the pin-making industry.

the huge demand for pins.

the division of labor.

Correct answer:

the division of labor.

Explanation:

The only point at which the author discusses the machinery involved in manufacturing pins is in the third paragraph, when he states, “A workman not educated to this business (which the division of labor has rendered a distinct trade), nor acquainted with the use of the machinery employed in it (to the invention of which the same division of labor has probably given occasion), could scarce, perhaps, with his utmost industry, make one pin in a day, and certainly could not make twenty.” The second parenthetical remark tells us that the author thinks that the division of labor likely gave rise to the machinery used in pin-making.
