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 31 to 35. Water is necessary for life. People can live only a few days without it. Yet, nearly 25 million people die each year because of it. Both industrial nations and less developed countries are worried about the quality and quantity of water in the world. The United Nations called the 1980s the World Water Decade. The UN hoped to provide pure water for everyone by 1990. One of the problems about water is distribution. Water is not always distributed in the areas where the large population centres are. Some regions get enough rain, but others are short of water. Over half of the world is without pure drinking water. Seventy-five percent of city people have safe water, but only 29 percent of rural people do. About 80 percent of all illness is related to bad water. Millions of women and children spend up to six hours a day carrying water. When these women finish carrying water and doing their domestic work, they don't have time for anything else. In some dry areas, children must stay home from school to help carry water. The United Nations hopes to change this situation. It is attempting to develop water systems in a lot of regions in the world. Villages will be able to create and take care of these systems themselves, and other villages can copy them. UNICEF, the World Bank, and other organizations are helping. Local, national, and international organizations must all work together to improve the quality of life of millions of people with pure water. 31.

Read the passage below and choose the correct answer among A, B, C or D. The World Health Organization (WHO) is a specialized agency of the United Nations that acts as a coordinating authority on international public health. Established on 7 April, 1948, and headquartered in Geneva, Switzerland, the agency inherited the mandate and resources of its predecessor, the Health Organization. The WHO's constitution, states that its objective is "the attainment by all peoples of the highest possible level of health." Its major task is to combat diseases, especially key infectious diseases, and to promote the general health of the people of the world. The WHO also sponsors programs to prevent and treat serious epidemics such as SARS, malaria, and AIDS.

The WHO is nearing success in developing vaccines against malaria and aims to eradicate polio within the next few years. The organization has already endorsed the world's first official HIV/AIDS Tool kit for Zimbabwe making it an international standard. In addition to its work in eradicating disease, the WHO also carries out various health-related campaigns, for example, to boost the consumption of fruits and vegetables worldwide and to discourage tobacco use. Experts met at the WHO headquarters in Geneva in February, 2007, and reported that their work on pandemic influenza vaccine development had achieved encouraging progress. More than 40 clinic trials have been completed or are ongoing. Most have focused on healthy adults.
