Example Input: Article: Disposing of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities,the waste disposal problem becomes increasingly difficult. During the eighteenth century,it was usual for several neighboring towns to get together to select a faraway spot as a dump site. People would transport household rubbish,rotted wood and old possessions to the site. Regularly some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by. Factories and some other industrial sites also had waste to be disposed of. Those located on rivers often just poured the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem. Several facts make these choices unacceptable to modern society. The first problem is space. Dumps , are most needed in heavily populated areas. Such areas rarely have empty land suitable. Farm areas are refusing to accept rubbish from elsewhere,cheap land in major city areas to dispose wastes is nonexistent . Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers,ground water,land and air is a price people can no longer pay to get rid of waste. The amount of waste,however, continues to grow. Recycling efforts have become commonplace,and many towns require their people to take part. Even the most efficient recycling programs,however,can hope to deal with only about 50 percent of a city's reusable waste,so more people should be involved in recycling programs.
Answer: Waste Disposal Problem

Example Input: Article: The Goldman Environmental Foundation recently recognized a group of individuals for their efforts to protect the environment. Each year, the American-based group honors environmental activists from six different areas. The first three winners of the 2012 Goldman Prize are from Kenya, the Philippines and China. The Goldman Environmental Foundation says Ikal Angelei is a hero to those who live around Lake Turkana. The Kenyan woman received the award because of her efforts to stop a dam project on a river in Ethiopia. Critics say the dam will harm the lake and restrict the flow of water for people who live nearby. The Philippine island of Mindoro is home to those who depend on the area's natural resources for food and jobs. Edwin Gariguez became concerned when a European company announced plans to mine for nickel on the island. The Roman Catholic minister said waste materials from the mining project would pollute the water and destroy the forests. So he started a campaign to stop the project. In China, Ma June is working with businesses to clean up their pollution. He formed a group that collects information about pollution, and publishes it on the Internet. The Goldman Prize was also awarded to activists from Argentina, Russia and the United States. Sofia Gatica of Argentina is from a town where farmers commonly use pesticide products to protect soybean crops from insects. The town also has a high rate of cancer. Miz Gatica believed that pesticide use was responsible for the death of her baby. She worked with other mothers to get government officials to ban the use of chemicals near populated areas. Evgenia Chirikova objects to the plans to build a road through a protected forest just outside Moscow. She has demanded that Russian officials redirect the road away from the forest. She and her followers have been arrested for their activities. However, their campaign has gained widespread public support. The sixth winner is American Caroline Cannon -- a community leader in Point Hope, Alaska. Miz Cannon is fighting to keep Arctic waters safe from oil and gas exploration.

Example Input: Article: There was once a farmer. His land was hilly and the soil was not the best. He had a cow that wasn't giving much milk and he had chickens who were laying few eggs. The place looked run-down and the barn and fences needed repair. The farmer and his wife felt _ . One stormy evening, a poorly-dressed man knocked on their door, asking if he could get shelter for the night. They shared the food that had been prepared, while they talked a great deal about the farm. When the stranger left the following morning, he thanked the farmer and his wife and pulled a little bag of gold pieces out of his pocket. He said that maybe this would help them. He added that he'd come by next year with hopes of finding a revived farm. After this, the farmer and his wife often talked about whether they should buy a more promising cow. Other times they considered whether they should buy chickens who laid more eggs. However, every conversation ended with the farmer trusting the farm would improve as he found himself fixing the barn and the fences, caring for the animals, preparing food for themselves and their animals. The farmer beamed when the stranger did come by again a year later. Everything looked so much better. The stranger asked, "What did you use the gold for?" The farmer said, "We hid the gold under a kitchen tile and, while we often thought of it, we never did think of anything we needed the gold for." Then the farmer added thoughtfully, "I do thank you, though, ever so much. You gave us what we really needed to keep going -- you lifted our spirits." Saying that, the farmer removed the tile and cheerfully returned the gold to the stranger.
