Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 55 to 64.

         Although they are an inexpensive supplier of vitamins, minerals, and high-quality protein, eggs also contain a high level of blood cholesterol, one of the major causes of heart diseases. One egg yolk, in fact, contains a little more than two-thirds of the suggested daily cholesterol limit. This knowledge has caused egg sales to plummet in recent years, which in turn has brought about the development of several alternatives to eating regular eggs. One alternative is to eat substitute eggs. These egg substitutes are not really eggs, but they look somewhat like eggs when they are cooked. They have the advantage of having low cholesterol rates, and they can be scrambled or used in baking. One disadvantage, however, is that they are not good for frying, poaching, or boiling. A second alternative to regular eggs is a new type of egg, sometimes called 'designer' eggs. These eggs are produced by hens that are fed low-fat diets consisting of ingredients such as canola oil, flax, and rice bran. In spite of their diets, however, these hens produce eggs that contain the same amount of cholesterol as regular eggs. Yet, the producers of these eggs claim that eating their eggs will not raise the blood cholesterol in humans.

         Egg producers claim that their product has been portrayed unfairly. They cite scientific studies to back up their claim. And, in fact, studies on the relationship between eggs and human cholesterol levels have brought mixed results. It may be that it is not the type of egg that is the main determinant of cholesterol but the person who is eating the eggs. Some people may be more sensitive to cholesterol derived from food than other people. In fact, there is evidence that certain dietary fats stimulate the body's production of blood cholesterol. Consequently, while it still makes sense to limit one's intake of eggs, even designer eggs, it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol level.

 

What is the meaning of 'back up'?

A. reverse

B. advance  

C. block 

D. support

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

Farming has come a long way since the days of horse-drawn plows, and now it’s heading swiftly into the twenty-first century. Research at Indiana’s Purdue University uses the Navistar Global Positioning System (GPS) to help increase crop yields and reduce chemical use. GPS uses satellite signals to determine location within inches. Under Purdue’s scheme, a farmer out in the field would use a GPS receiver mounted on his vehicle to pinpoint his position. A computer linked to the receiver and programmed with the field’s soil conditions – which can vary widely from one area to another – would tell the farmer precisely where the plant and how much pesticide and fertilizer to use at that specific site. “Currently the number one cost to the famer is chemicals” say Gary Kurtz, a Professor of Agriculture Engineering at Purdue. Site-specific farming can increase yields while reducing chemical use.

But the cost of this new technology may be too high for the small farmer. The cost of taking and testing soil samples every few feet in a farmer’s field is a limiting factor. Soil tests can run $7 to  $8 each. Mark Morgan, assistant Professor of Agriculture Engineering at Purdue and his graduate assistants are working on a sensor to be attached to the front of a farm implement, enabling the farmer to perform his own soil tests on the go.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

How is the news different from entertainment? Most people would answer that news is real but entertainment is fiction. However, if we think more carefully about the news, it becomes clear that the news is not always real. The news does not show us all the events of the day, but stories from a small number of chosen events. The creation of news stories is subject to specific constraints, much like the creation of works of fiction. There are many constraints, but three of the most important ones are. commercialism, story formulas, and sources. Newspapers, radio, and TV stations are businesses, all of which are rivals for audiences and advertising revenue. The amount of time that the average TV station spends on news broadcasts has grown steadily over the last fifty years - largely because news is relatively cheap to produce, yet sells plenty of advertising. Some news broadcasts are themselves becoming advertisements. For example, during one week in 1996 when the American CBS network was airing a movie about the sinking of the Titanic, CBS news ran nine stories about that event (which had happened 84 years before). The ABC network is owned by Disney Studios, and frequently runs news stories about Mickey Mouse. Furthermore, the profit motive drives news organizations to pay more attention to stories likely to generate a large audience, and to shy away from stories that may be important but dull. This pressure to be entertaining has produced shorter, simpler stories. more focus on celebrities than people of substance, more focus on gossip than on news, and more focus on dramatic events than on nuanced issues.

As busy people under relentless pressure to produce, journalists cannot spend days agonizing over the best way to present stories. Instead, they depend upon certain story formulas, which they can reuse again and again. One example is known as the inverted pyramid. In this formula, the journalist puts the most important information at the beginning of the story, than adds the next most important, and so on. The inverted pyramid originates from the age of the telegraph, the idea being that if the line went dead halfway through the story, the journalist would know that the most crucial information had at least been relayed. Modern journalists still value the formula for a similar reason. Their editors will cut stories if they are too long. Another formula involves reducing a complicated story into a simple conflict. The best example is "horse race" election coverage. Thorough explication of the issues and the candidates' views is forbiddingly complex. Journalists therefore concentrate more on who is winning in the opinion polls, and whether the underdog can catch up in the numbers than on politicians' campaign goals.

Sources are another constraint on what journalists cover and how they cover it. The dominant sources for news are public information officers in businesses and government offices. The majority of such officers try to establish themselves as experts who are qualified to feed information to journalists. How do journalists know who is an expert? In general, they don't. They use sources not on the basis of actual expertise, but on the appearance of expertise and the willingness to share it. All the major news organizations use some of the same sources (many of them anonymous), so the same types of stories always receive attention. Over time, the journalists may even become close friends with their sources, and they stop searching for alternative points of view. The result tends to be narrow, homogenized coverage of the same kind.

The word them in paragraph 4 refers to _________.

A. journalists

B. organizations

C. experts

D. sources

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 44 to 55.

         Panel painting, common in thirteenth- and fourteenth-century Europe, involved a painstaking, laborious process. Wooden planks were joined, covered with gesso to prepare the surface for painting, and then polished smooth with special tools. On this perfect surface, the artist would sketch a composition with chalk, refine it with inks, and then begin the deliberate process of applying thin layers of egg tempera paint (egg yolk in which pigments are suspended) with small brushes. The successive layering of these meticulously applied paints produced the final translucent colors.

         Backgrounds of gold were made by carefully applying sheets of gold leaf, and then embellishing of decorating the gold leaf by punching it with a metal rod on which a pattern had been embossed. Every step in the process was slow and deliberate. The quick-drying tempera demanded that the artist know exactly where each stroke be placed before the brush met the panel, and it required the use of fine brushes. It was, therefore, an ideal technique for emphasizing the hard linear edges and pure, fine areas of color that were so much a part of the overall aesthetic of the time. The notion that an artist could or would dash off an idea in a fit of spontaneous inspiration was completely alien to these deliberately produced works.

         Furthermore, making these paintings was so time-consuming that it demanded assistance. All such work was done by collective enterprise in the workshops. The painter or master who is credited with having created the painting may have designed the work and overseen its production, but it is highly unlikely that the artist’s hand applied every stroke of the brush. More likely, numerous assistants, who had been trained to imitate the artist’s style, applied the paint. The carpenter’s shop probably provided the frame and perhaps supplied the panel, and yet another shop supplied the gold. Thus, not only many hands, but also many shops were involved in the final product.

         In spite of problems with their condition, restoration, and preservation, many panel paintings have survived, and today many of them are housed in museum collections. 

 

The author mentions all of the following as problems with the survival of panel paintings EXCEPT ______.

A. condition

B. restoration 

C. preservation

D. theft
