Article: The red crab lives on Christmas Island in the Indian Ocean and has been found nowhere else in the world. But on its homeland it is a very significant species -- some 120 million individuals cover the rain forest floor and play a major role in determining the structure of the ecosystem. These large crabs are active during the day but prefer to stay in the shade and can die in the heat of direct sunlight. They feed on fallen leaves, seeds, fruits and flowers, recycling nutrients and helping to determine the spread and composition of native plants. Most of the year the red crabs live in the holes they dig throughout the forest. During the dry season they hide in these shelters to keep their body wet and remain there for two to three months. But when wet season returns in October or November they begin a legendary mass migration to their seaside breeding grounds, moving in color1ful wave that wash over all obstacles like roads (including special passages and some closed roads built for the red crab) and even seaside cliffs. The annual migration is also closely tied to the lunar schedule. The crabs arrive at the coast and breed at such a time that the females can produce eggs and develop them in caves for a dozen or so days before carrying them into the sea exactly when high tide turns between the last quarter and new moon. During this period sea level on the beaches varies the least and offers an easier approach, which is so important that if the weather delays the migration crabs will put off laying eggs until the next lunar month. Red crab eggs grow right away, and the young live in the sea for a month before returning to the coast, changing into air breathers, and slowly returning inland to begin the cycle once again.

Article: A senior United Nations Children's Fund (UNICEF) official on May 29 praised China for its remarkable achievements in children s welfare. A. H. M. Farook, UNICEF's operations area officer for China and Mongolia said that China "can be very satisfied to tell the whole world what can be done with limited resources to help its children to grow healthily and happily." China's child population makes up one-filth of the world's total. "The reason behind the tremendous achievement is China's long tradition of caring for children home at home and in society." he said. "What's more is that Chinese people have always given special attention to children who are in special need." The UN official made the remarks when addressing a group of 50 children and staff from the Beijing Children's Welfare Home at the Shangri-la Hotel, Beijing. The hotel invited the orphans to share snacks, sing, dance and play games at a park inside the hotel for a "Share the Sunshine" party, as a prelude to celebrations to mark the Children's Day. The Beijing children s Welfare Home, set up soon after New China, was founded in 1949, has at present more than 400 children. A leading official of the welfare institution said that the children live a happy life and that the agency spends about 400 yuan a month for an average orphan. An average Chinese worker earned 440 yuan a month during the first quarter this year. Gu Xiaojin, deputy secretary-general of the China Youth Development foundation (CYDF), said people from all walks of life had contributed to the welfare of the Chinese children. She said that CYDF set up the Project Hope in 1989, which calls on people across the country to donate money to help poor children to continue their schooling. By the end of last year, she said, CYDF had collected nearly 700 million yuan in donations, which has helped the establishment of 2, 074 Hope primary schools and enabled more than 1.25 million dropouts to return to school classrooms. Three "Hope Stars" also attended the party. They were model teenagers chosen among students who are economically supported by the Project Hope to further their nine-year compulsory studies in the poverty-stricken regions. They will be torchbearers for the Chinese Team for the upcoming Atlanta Olympic Games this year.

question:
Article: Educating Girls Is a Real Lifesaver Clare Short knows it. Every developing economist knows it. The World Bank knows it. The education of girls is the surest way to reduce poverty. The reason is simple. All the evidence shows that taking girls out of the fields and homes, and putting them behind desks, raises economic productivity, lowers infant and maternal death rates, reduces birth rates, and improves environmental management. Why, then, are 90 million primary school-age girls around the world not in school? For the same reason that when Charles Dickens was writing David Copperfield 150 years ago girls were absent from the British education system: Men in power mostly prefer _ that way, or are not interested enough in changing the situation to commit energy and money to doing so. The countries with the poorest record for having women in positions of power or influence have the worst figures for girls' education. High-profile intervention by organizations such as the World Bank has begun successfully with several countries, and more of the same will probably be needed to bring change in conservative, male-run states. Even if there were no development payoff from gender equality in schools, the education of girls would still be a cause worth fighting for. Education is a human right, and the denial of it to girls is a scar on the community in the twenty-first century. To be born a girl in a rural area in Nepal, Pakistan, Indonesia, Morocco, Togo, or Sudan -- half a dozen of the most shameful performers -- means being condemned to a life without school, education, or clean water, marriage and babies coming too early, too many births, children who die of preventable diseases, backbreaking work in the fields, subordination to husband and his family, and an early death. Every year, almost 12 million children under the age of five needlessly die of infectious diseases associated with poverty. But each additional year spent by their mothers in primary school lowers the risk of premature child deaths by about 8 percent. In Pakistan, an extra year of school for 1,000 girls could prevent sixty infant deaths. With women and girls being the main farmers in Africa and southern Asia, their education offers a chance to develop more efficient farming practices, improve output, and raise awareness of the ecological needs of the land with tree planting and farming. Therefore, the world community cannot afford to ignore this avenue of change.
Question: Which is Not the reason why educating girls reduces poverty?
Options: (A) It improves environmental management. (B) It raises economic productivity. (C) It creates more children. (D) It lowers maternal death rates.
answer:
C
