"The Aging of Public Transportation Systems" by Matthew Minerd (2013)

As cities develop, their public transportation systems often show signs of aging that are mixed with aspects that are quite up-to-date.  An example of such a situation can be found in the transportation system in Washington DC. This system is made up of a mixture of buses and trains that connect people to locations in DC, Maryland, and Virginia. While the system has been well maintained and updated over the years, it still shows evidence that certain sections are older than others.

This is particularly noticeable when one considers the multiple lines that connect in Washington DC itself. Within the city, there are five different sets of tracks that run in various directions and to sundry places. A number of the newer lines are in excellent condition and rarely break down; however, the case of the red line is somewhat different. This oldest line of the metro train system often has issues because of its age, experiencing a number of track and signal issues even at rush hour when the overall system is its most efficient. Admittedly, the transportation authority is working to update this line and make it less problematic. Still, until this work is completed, it is obvious to all who are familiar with the metro train system that the red line is the oldest and most out of date.

Why is it obvious to all who are familiar with the metro train system that the red line is the oldest and most out of date?

"Conservatism" by Matthew Minerd (2013)

In American politics, there is perhaps no word that is more over-simplified than “conservative.” Many people use this term as though it has a single meaning and expresses a single historical-political outlook. Nothing could be further from the truth. The development of American conservatism must be understood as a combination of a number of strands of ideology that often coexist with great tension and difficulty. Although there are many groups that are combined in this larger assortment, two examples will suffice to show the great diversity present in this seemingly simple group.

For instance, there are the “traditionalist conservatives,” who generally are concerned with preserving Western culture and tradition against the developments of modern thought and culture. In many ways, this type of conservatism is the most “conserving”; that is, traditionalists are primarily concerned with maintaining the “old order” of Western civilization and learning. Because of these concerns, the traditionalist conservatives are very wary of any kind of major governmental program that promises to bring a “new order” into existence. While not disagreeing with the idea of progress, these conservatives believe that any such changes should occur organically, in a natural manner over a period of years. 

On the other hand, there are also the “libertarians," who are often classed as “conservatives” as well. They are surprisingly different from the traditionalist conservatives. The libertarians are primarily concerned with maximizing freedom and limiting the role of government in individual lives. In many ways, they represent the kind of modern individualism disagreed with by the traditionalists.

These two opposed groups are able to come together in the general notion of “conservatism” because of their shared attitudes toward the government, particularly the federal government. The traditionalists wish to limit the role of the federal government out of a fear that it will ruin traditional culture through radically new plans and agendas. The libertarians seek to limit it out of a desire to give individual citizens maximum freedom of choice and action. While these two branches of “conservatism” are in many ways opposed to each other, they somehow manage to coexist along with many other positions that are all called “conservative” in spite of similarly striking differences.

Based on what the author has said, why might it be fair to say that traditionalist conservatives most closely deserve the title “conservative” in the strict sense of that word?

"The Meaning of 'Liberal Arts Education'" by Matthew Minerd (2013)

Many people use the expression “liberal arts education” but do not know much at all about the original meaning of such an education. It is often thought that a “true liberal education” is one that gives the student knowledge that is not pursued for “utilitarian values”—that is, knowledge that is not merely “for the sake of getting a job.” Sometimes, the expression “liberal education” is used to describe an education that is not a mere repetition of old beliefs, but is open-minded and “liberal” in this way.

To understand the original meaning of the expression “liberal arts” it is necessary to consider each part of the expression as it was used in its ancient and medieval senses. The word “liberal” was used to describe these “arts” insofar as they were not the “servile arts,” that is, “arts” in the sense of “artisan work.” In this regard, “liberal arts” were not a matter of “getting a job.” The word “art” still had a meaning that was related to “artisanship.” However, these “arts” were “liberal” because they were the “arts of reasoning,” that is, “the arts of the mind.” They were meant to be tools that prepared someone for more in-depth studies. Thus, they were not envisioned as “knowledge for the sake of knowledge.” Instead, they were the initial tools that enabled the young student to reason properly.  This more ancient sense of the “liberal arts” is often missed or, at least, partially overlooked in contemporary discussions about them.

According to the reasoning of the passage, which sentence directly explains the older meaning of “art” in the expression “liberal arts”?

Adapted from "Errors in Our Food Economy" in Scientific American Supplement No. 1082 Vol. XLII (September 26th, 1896)

Scientific research, interpreting the observations of practical life, implies that several errors are common in the use of food.

First, many people purchase needlessly expensive kinds of food, doing this under the false impression that there is some peculiar virtue in the costlier materials, and that economy in our diet is somehow detrimental to our dignity or our welfare. And, unfortunately, those who are most extravagant in this respect are often the ones who can least afford it.

Secondly, the food which we eat does not always contain the proper proportions of the different kinds of nutritive ingredients. We consume relatively too much of the fuel ingredients of food, such as the fats of meat and butter, and the starch which makes up the larger part of the nutritive material of flour, potatoes, sugar, and sweetmeats. Conversely, we have relatively too little of the protein of flesh-forming substances, like the lean of meat and fish and the gluten of wheat, which make muscle and sinew and which are the basis of blood, bone and brain.

Thirdly, many people, not only the well-to-do, but those in moderate circumstances, use needless quantities of food. Part of the excess, however, is simply thrown away with the wastes of the table and the kitchen; so that the injury to health, great as it may be, is doubtless much less than if all were eaten. Probably the worst sufferers from this evil are well-to-do people of sedentary occupations.

Finally, we are guilty of serious errors in our cooking. We waste a great deal of fuel in the preparation of our food, and even then a great deal of the food is very badly cooked. A reform in these methods of cooking is one of the economic demands of our time.

The primary argument of the second paragraph is that _________.

Adapted from "Wild Animals in Captivity" by W. A. Atkinson in Chatterbox Periodical (1906, ed. J. Erskine Clark)

Notwithstanding all the care which is now bestowed upon wild animals in our zoological gardens and menageries, nearly all of them suffer a little in some way or other by confinement. When we think of the great difference which exists between the surroundings natural to a free wild animal, and those of even the best zoological gardens, we cannot but be surprised that so many animals from all parts of the world can be kept alive and in good condition in a climate so changeable as ours. Every effort is made by the keepers to copy as far as possible the natural conditions to which each animal is accustomed.

It was usual, for instance, to deprive all the flesh-eating animals of one of the greatest traveling menageries of food during one day in each week. It was found by experience that the animals were healthier when they suffered periods of fasting like this, than they were when they were fed regularly every day without a break. The explanation of this was very simple. These animals, when they were living wild in the jungles, forests, deserts, or ice-fields, obtained all their food by hunting. When game was scarce or difficult to catch, they were compelled to go hungry; and this occurred so often as to be a natural condition to which they were well accustomed. When, therefore, they were placed in cages, and were fed as regularly, though not as frequently as human beings, their health was more or less impaired.

Animals in confinement often undergo slight changes even when no alteration in their appearance or falling-off in health is noticeable. Many of them, for instance, rarely have young ones, and even when they have, the young are seldom as healthy and robust as if born in a wild state. The keepers have frequently the utmost difficulty in rearing animals which are born in menageries and zoological gardens. Yet if these animals were born in their own countries and under natural conditions, they would grow up healthy and strong, without receiving any more care than a kitten receives from its mother.

An incident which occurred in the Zoo not long ago affords a striking illustration of these facts. A wolf had an ordinary family of eight young ones. The keepers, probably thinking that these were too many for the captive wolf to bring up alone, divided the family. Four of them were left with their mother, and four of them were placed in charge of a collie. The dog took kindly to her foster-children, and reared them successfully with her own. This was only what the keepers expected. But when they placed the young ones together again, and compared the collie's family with the wolf's family, they were surprised to find that the four which had been nurtured by the collie were stronger and better animals than their four brothers and sisters. The best explanation of this result is that the collie was living a healthy natural life, while the wolf, though to all appearance quite well, was not enjoying the full vigor which results from a free and active life.

According to the passage, why is it better for meat-eating animals kept in captivity to occasionally be denied a daily meal?

"The Difficulties of Writing One's First Research Paper" by Matthew Minerd (2013)

When a high school student writes his or her first research paper, he or she likely will face a number of difficulties in finding and using sources for the essay. The single most significant of these difficulties is the finding of sources for the paper. The student will likely only know about his or her topic from the discussion that has occurred in class, based on the textbook that is being used. For a research paper, however, it will be necessary to find appropriate texts in the library to support the topic about which he or she is writing. This can be quite overwhelming, for there are often so many books on a given topic that it is difficult to know where to begin if your starting point is only a high school textbook. Many students will be tempted to use every book that they find, not focusing on the most appropriate texts for the topic. On the other hand, some students will rely heavily on a single book on the topic. In this case, many things are overlooked because of the student’s narrow research. Of course, there are a number of other difficulties involved in the writing of such a paper, but the use of sources likely remains the most troublesome by far.

Which sentence explains why students experience difficulties choosing the appropriate kinds and quantities of texts for their first research papers?
