Example Input: Article: Mattel Inc. is _ 4.4 million Polly Pocket toys with magnets after some of them caused serious injuries to children who swallowed magnets that fell off. Tiny magnets inside the toys may fall off without being noticed by parents and babysitters. The magnets can be swallowed or placed in children's noses or ears. When more than one magnet is swallowed, the magnets can attract each other and cause intestine perforation which can be deadly. The Consumer Product Safety Commission(CPSC)received 170 reports of the small magnets coming out of these recalled toys. There were three reports of serious injuries to children who swallowed more than one magnet. All three suffered intestinal perforations that required operation. A 2-year-old child stayed in hospital for seven days and a 7-year-old child was hospitalized for 12 days. An 8-yeal-old child was also hospitalized. The recalled Polly Pocket toys contain plastic dolls and accessories that have small magnets. The magnets measure one-eighth inch in diameter and are fixed in the hands and feet of some dolls, and even in the plastic clothing, hairpieces and other accessories to help the pieces stay on the doll or the doll's house. The model number is printed on the bottom of the largest pieces on some of the toys. Contact Mattel if you cannot find a model number on your product to determine if it is part of the recall. Polly Pocket magnetic toys currently sold in stores are not included in this recall. The model numbers included in the recall are: B2632, B3158, B3201, B7118, G8605, H1537, H1538 and H3211. The toys were on sales in department stores and toy stores from May 2006 through September 2009 for between $15 and $30. Consumers should immediately take these recalled toys away from children and contact Mattel for the return of the toys. For more information contact Mattel at 888 597-6597 anytime or visit the company's Web site.

Example Input: 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.
Example Output: C
