Read the following passage and mark the letter A, B, C or D to indicate the correct answer.

The Nobel Peace Prize is awarded annually and the first woman to win this prize was Baroness Bertha Felicie Sophie von Suttner in 1905. In fact, her work inspired the creation of the Prize. The first American woman to win this prize was Jane Addams, in 1931. However, Addams is best known as the founder of Hull House.

Jane Addams was born in 1860, into a wealthy family. She was one of a small number of women in her generation to graduate from college. Her commitment to improving the lives of those around her led her to work for social reform and world peace. In the 1880s Jane Addams traveled to Europe. While she was in London, she visited a ‘settlement house’ called Toynbee Hall. Inspired by Toynbee Hall, Addams and her friend, Ellen Gates Starr, opened Hull House in a neighborhood of slums in Chicago in 1899. Hull House provided a day care center for children of working mothers, a community kitchen, and visiting nurses. Addams and her staff gave classes in English literacy, art, and other subjects. Hull House also became a meeting place for clubs and labor unions. Most of the people who worked with Addams in Hull House were well educated, middle-class women. Hull House gave them an opportunity to use their education and it provided a training ground for careers in social work.

Before World War I, Addams was probably the most beloved woman in America. In a newspaper poll that asked, “Who among our contemporaries are of the most value to the community?”, Jane Addams was rated second, after Thomas Edison. When she opposed America’s involvement in World War I, however, newspaper editors called her a traitor and a fool, but she never changed her mind. Jane Addams was a strong champion of several other causes. Until 1920, American women could not vote. Addams joined in the movement for women’s suffrage and was a vice president of the National American Woman Suffrage Association. She was a founding member of the National Association for the Advancement of Colored People (NAACP), and was president of the Women’s International League for Peace and Freedom. . Her reputation was gradually restored during the last years of her life. She died of cancer in 1935.

The word “their” in line 16 refers to

A. children of working mothers

B. middle-class women

C. visiting nurses

D. labor union members

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 following questions

          The dream of a canal across the Isthmus of Suez had existed since the time 4,000 years ago when the pharaohs built Egypt's first canal. (It linked the Nile River with the Great Bitter Lake, which then opened onto the Gulf of Suez.) This canal, however, was filled in, and for centuries trade with the Far East was carried overland across Asia. Eventually ships began to sail around the southern tip of Africa to reach the Mediterranean Sea from the Red Sea.

          Then in 1858 a French engineer, Ferdinand de Lesseps, acquired the rights from his friend, Said Pasha, viceroy of Egypt, to organize a company and build a canal. On November 17, 1869, the Suez Canal was opened with great ceremony at the northern terminus, Port Said, which was named for Said Pasha. The 12,400-mile (19,950-kilometer) voyage from London around South Africa to Bombay, India, was shortened to 7,250 miles (11,670 kilometers).

The Suez Canal is 101 miles (163 kilometers) long, or about twice the length of the Panama Canal. The Suez was easier to construct because it crosses flat, sea-level terrain and requires no locks. About 24 miles (39 kilometers) of the canal are channels dredged through lakes. Most of the banks of the other 77 miles (123 kilometers) are reinforced with stone, cement, or steel to help prevent erosion.

The main channels of the canal are dredged to a depth of about 66 feet (20 meters), and the navigational width between buoys is set at 596 feet (180 meters). Double channels, where ships traveling in opposite directions can pass without stopping, have been constructed at four locations and cover a little more than 41 miles (67 kilometers). The largest ships allowed to pass through the canal may have a beam of up to 210 feet (64 meters) wide and a draught (belowwater depth) of up to 53 feet (16 meters).

Ships move through the canal under their own power, but large ships must be accompanied by a tugboat. The trip takes roughly 12 to 18 hours. To prevent accidents, vessels must travel in convoys at fixed speeds, fixed intervals and fixed distances between passing ships. Convoys going in opposite directions are usually timed so they will pass each other in the Great Bitter Lake where there is a long double channel.

Each day two convoys from south to north and one convoy from north to south sail through the canal, with a maximum total of 80 vessels a day. Yearly traffic numbers about 20,000 ships carrying between 300 million and 400 million net tons. Tankers and cargo ships account for nearly all canal traffic, but occasionally passenger liners and warships use the waterway. Northbound cargo is chiefly oil from the Persian Gulf headed for Western Europe. Southbound cargo consists mainly of manufactured goods and grain from Europe and North America destined for the Far East and southern Asia.

After the digging of the Suez Canal, the whole voyage from London to India was _______. 

A. reduced by 11,670 kilometers

B. 12,400 miles 

C. 7,250 miles 

D. 19,950 kilometers

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 43 to 50.

        An air pollutant is defined as a compound added directly or indirectly by humans to the atmosphere in such quantities as to affect humans, animals, vegetation, or materials adversely. Air pollution requires a very flexible definition that permits continuous changes. When the first air pollution laws were established in England in the fourteenth century, air pollutants were limited to compounds that could be seen or smelled - a far cry from the extensive list of harmful substances known today. As technology has developed and knowledge of the health aspects of various chemicals has increased, the list of air pollutants has lengthened. In the future, even water vapor might be considered an air pollutant under certain conditions.

        Many of more important air pollutants, such as sulfur oxides, carbon monoxides and nitrogen oxides are found in nature. As the Earth developed, the concentration of these pollutants was altered by various chemical reactions; they became components in biogeochemical cycles. These serve as an air purification scheme by allowing the compounds to move from the air to the water or soil. On a global basis, nature's output of these compounds dwarfs that resulting from human activities.

        However, human production usually occurs in a localized area, such as a city. In such a region, human output may be dominant and may temporarily overload the natural purification scheme of the cycles. The result is an concentration of noxious chemicals in the air. The concentrations at which the adverse effects appear will be greater than the concentrations that the pollutants would have in the absence of human activities. The actual concentration need not be large for a substance to be a pollutant; in fact, the numerical value tells us little until we know how much of an increase this represents over the concentration that would occur naturally in the area. For example, sulfur dioxide has detectable health effects at 0. 08 parts per million (ppm), which is about 400 times its natural level. Carbon monoxide, however has a natural level of 0. 1 ppm and is not usually a pollutant until its level reaches about 15 ppm.

For which of the following reasons can natural pollutants play an important role in controlling air pollution?

A. They're less harmful to living beings than other pollutants. 

B. They function as part of a purification process.

C.They occur in greater quantities than other pollutants.

D. They have existed since the Earth developed.
