The modern comic strip started out as ammunition in a newspaper war between giants of the American press in the late nineteenth century. The first full-color comic strip appeared January 1894 in the New York World, owned by Joseph Pulitzer. The first regular weekly full-color comic supplement, similar to today's Sunday funnies, appeared two years later, in William Randolph Hearst's rival New York paper, the Morning Journal.
Both were immensely popular, and publishers realized that supplementing the news with comic relief boosted the sale of papers. The Morning Journal started another feature in 1896, the "Yellow Kid," the first continuous comic character in the United States, whose creator, Richard Outcault, had been lured away from the World by the ambitious Hearst. The "Yellow Kid" was in many ways a pioneer. Its comic dialogue was the strictly urban farce that came to characterize later strips, and it introduced the speech ballon inside the strip, usually placed above the characters' heads.
The first strip to incorporate all the elements of later comics was Rudolph Dirks's "Katzenjammer Kids," based on Wilhelm Busch's Max and Moritz, a European satire of the nineteenth century. The "Kids" strip, first published in 1897, served as the prototype for future American strips. It contained not only speech balloons, but a continuous cast of characters, and was divided into small regular panels that did away with the larger panoramic scenes of earlier comics.
Newspaper syndication played a major role in spreading the popularity of comic strips throughout the country. Though weekly colored comics came first, daily black-and-white strips were not far behind. The first appeared in the Chicago American in 1904. It was followed by many imitators, and by 1915 black-and-white comic strip had become a staple of daily newspapers around the country.
The word “it” refers to _________.
A.The“Yellow Kid”
B.dialogue                  
C.farce                       
D.balloon

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.
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 disease. 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 turns 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 lower 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.
Eggs 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 30 dietary fat will probably not help reduce the blood cholesterol level.
According to the passage, one yolk contains approximately what fraction of the suggested daily limit for human consumption of cholesterol?
A.1/2        
B. 1/3 
C.3/4 
D.2/3
