Read the following passage and choose the best answer (A, B, C, D):
Aspirin's origins go back at least as early as 1758. In that year, Englishman Edward Stone noticed a distinctive bitter flvor in the bark of the willow tree. To Stone, this particular bark seem to have much in common with "Peruvian Bark", which had been used medicinally since the 1640s to bring down fevers and to treat malaria, stone decided to test the effectiveness of the willow bark. He obtained some, pulverized it into tiny pieces, and conducted experiments on its properties. His tests demonstrated that this pulverized willow bark was effective both in reducing high temperatures and in relieving aches and pains. In 1763, stone presented his tiding to the British Royal Society. Several decades later, further studies on the medicinal value of the willow bark were being conducted by two Italian scientists. These chemists, Brugnatelli and Fontana, determined that the active chemical that was responsible for the medicinal characteristics in the willow bark was the chemical salicin, which is the active ingredient of today's aspirin. The name "aspirin" is the trade name of the drug based on the chemical salicin, properly known as acetylsalicylic acid.The trade name "aspirin" was invented for the drug in the 1890s by the Bayer Drug Company in Germany. The fist bottles of aspirin actually went on sale to the publicjust prior to the turn of the century, in 1899.

Cleaning the World’s Oceans
Imagine taking a romantic walk on the beach with your loved one. As the sun begins to set, you hope to treasure this moment forever. Just then, your bare feet stumble over something and you hear a crack. You have just stepped upon a plastic soda bottle and some junk that the tide has washed ashore. Scenarios like this are happening more frequently due to an access amount of sea rubbish, and the worst of it is found far from land. The increasing accumulation of garbage in oceans is due to a number of factors. Studies suggest that 80 percent of all debris originated on land. The majority of this waste is in the form of plastics. This is particularly troublesome because plastic does not degrade at the same rate that other materials do. Therefore, these articles will remain there for quite some time. Some of the pollution is caused accidentally. For example, about 10,000 product-filled containers are lost at sea every year by freight ships. In other cases, the littering is more deliberate, such as the moment when people toss things into the water from boats or land. One of the most startling discoveries of recent years was an area which is now dubbed the Great Pacific Garbage Patch. It is a large collection of marine debris that collected in the North Pacific Ocean. Although the patch is quite massive, it is undetectable from satellites in space because most of the rubbish is underneath the surface. It was discovered in 1997 by a man who happened to spot it while returning home from a sailing race. The patch formed as a result of rubbish being carried by currents and then getting trapped in the area. Thankfully, the problem of ocean garbage is not being ignored. Organizations like the National Oceanic and Atmospheric Association (NOAA) are taking action. It has funded 76 projects that take an aggressive approach to eliminating sea rubbish. Since 2006, it has removed 3,814 metric tons of marine debris from oceans. Methods of rubbish removal include using machines that skim the surface of ocean waters and remove any drifting materials found. In addition, special traps are set by the mouths of rivers to snatch rubbish before it reaches the sea. If everyone does their part, sea rubbish seems like an issue that can be resolved.

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:
As working women continue to receive better and better wages, housewives still work at home without receiving pay – checks. Should a woman who works at home, doing the housework and caring for children, be paid for her service? In a 1986 study at Cornell University, sociologists found that the value of the services of a housewife averaged $ 11,600 a year. This rate was based on a family composed of a husband, wife, and three young children. The $ 11,600 is what the husband would have to pay if he hired others to take over his wife’s household chores. The researchers concluded that it would be fair for husbands to pay wives according to federal guidelines for minimum wages.
Another plan for rewarding women who work at home has been suggested by a former Secretary of Health and Human Services. He says that full-time housewives should be allowed to pay social security taxes, with their employers contributing part of the payment. He feels that the present system is unfair. He said, “ If you stay at home and raise a family, nobody will give you credit for it.”

The word “employers” in the passage refers to     .

Early peoples had no need of engineering works to supply their water. Hunters and nomads camped near natural sources of fresh water, and populations were so sparse that pollution of the water supply was not a serious problem. After community life developed and agricultural villages became urban centres, the problem of supplying water became important for inhabitants of a city, as well as for irrigation of the farms surrounding the city. Irrigation works were known in prehistoric times, and before 2000 BC the rulers of Babylonia and Egypt constructed systems of dams and canals to impound the flood waters of the Euphrates and Nile rivers, controlling floods and providing irrigation water throughout the dry season. Such irrigation canals also supplied water for domestic purposes. The first people to consider the sanitation of their water supply were the ancient Romans, who constructed a vast system of aqueducts to bring the clean waters of the Apennine Mountains into the city and built basins and filters along these mains to ensure the
clarity of the water. The construction of such extensive water-supply systems declined when the Roman Empire disintegrated, and for several centuries local springs and wells formed the main source of domestic and industrial water. The invention of the force pump in England in the middle of the 16th century greatly extended the possibilities of development of water-supply systems. In London, the first pumping waterworks was completed in 1562; it pumped river water to a reservoir about 37 m above the level of the River Thames and from the reservoir the water was distributed by gravity, through lead pipes, to buildings in the vicinity. Increased per-capita demand has coincided with water shortages in many countries. Southeast England, for example, receives only 14 per cent of Britain's rainfall, has 30 per cent of its population, and has experienced declining winter rainfall since the 1980s.
In recent years a great deal of interest has been shown in the conversion of seawater to fresh water to provide drinking water for very dry areas, such as the Middle East. Several different processes, including distillation, electrodialysis, reverse osmosis, and direct-freeze evaporation, have been developed for this purpose. Some of these processes have been used in large facilities in the United States. Although these processes are successful, the cost of treating seawater is much higher than that for treating fresh water.

For several centuries after the disintegration of the Roman Empire, the main source of water supply was from _ .
