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 centers, 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, has30 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.

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 22 to 28.
The Internet started out as a limited network called the ARPANET (Advanced Research Projects Agency Network). It was a network of computers that allowed communication even if computer became non-functioning. It was the academic and scientific community that adopted Internet, using a protocol called TCP/IP. TCP/IP allows a number of different network computers to be connected together. This is called the Internet. The Internet allows the creation the World Wide Web or the Web for short. The Web consists of Internet sites that allow data to be shared by others. Aside from making the Web possible, the Internet also makes e-mail, chat rom and file-sharing and telephoning possible. It even allows people to watch media and play games.
The Web can be read in a browser. A browser is simply a software program that uses HTTP (Hyper Text Transfer Protocol) data transmission. This will allow you to view Web pages. HTTP let you browser read the text, graphics, animation, video and music that are on the Web page. It also enables you to click on a link on the page using the mouse. The links on a Web page that guide you to go from one Web page to another are called hyperlinks. A Web page usually contains many hyperlinks so that you can “browse” the Internet. It is much like reading a book. You can go from page to page and get new information. One example of a browser is Internet Explorer. In the address box of your browser, you can type in an address called a URL for “uniform resource locator”.
To be able to use the Internet, you must have a computer with an Internet connection and software that lets you view that Web pages. Internet connection is called a dial-up connection. It needs the use of your telephone to connect your computer to an Internet service. A faster type of connection is called broadband. This requires a cable or some other equipment. If you turn on the computer with a broadband connection, it connects you the Internet at a time.
