Example Input: Article: A machine which makes water out of air could become the greatest household invention since the microwave. Using the same technology as a dehumidifier , the Water Mill is able to create a ready supply of drinking water by getting it from a limitless source-the air. The company behind the machine says not only does it offer all alterative to bottled water in developed countries,but it is a solution for the millions who face a daily water shortage. The machine works by drawing in damp air through a filter and over a cooling element which changes it into water droplets.It can produce up to 12 liters a day.The Water Mill will also produce more water when storms pass over, as the humidity in the air increases.In keeping with its ecodevelopment,the machine uses the same amount of electricity as three light bulbs. Inventor Jonathan Ritchey said:"The demand for water is .People are looking for freedom from water distribution systems that are shaky and unreliable". The machine,which is about 3 feet wide,is likely to costPS800 when it goes on sale here in the spring.Its maker, Canadian firm Element Four, estimates that a liter of water will cost around 20 pence to produce. Environmentalists claim half the world's population will face water shortage because of climate change by 2080.One in five humans is said to lack access to safe drinking water.

Example Input: Article: For the first time in modem history, less than half of theprefix = st1 /U.S.adult population now reads literature, according to a recent survey. Reading at Risk: A Survey of Literary Reading inAmericapresents a detailed review of the decline of reading's role in the nation's culture. Readingat Risk is a survey of national fashion in adult literary reading. The data source for Reading at Risk is as reliable and objective as any such survey can be. The key results of the survey are presented in the "Summary", but the report can be further explained as: literary reading in Americais not only declining rapidly among all groups, but the rate of decline has been speeded up, especially among the young.Readingat Risk merely shows a great _ that most Americans have already noted - our society's great turn to electronic media for entertainment and information. Reading a book requires a degree of active attention and devotion. Indeed, reading itself is a progressive skill that depends on years of education and practice. On the contrary, most electronic media such as television, recordings, and radio make fewer demands on their audiences, and indeed often require no more than passive participation. While oral culture has a rich reality and electronic media offer the considerable advantages of variety, print culture affords irreplaceable forms of focused attention and thought that make various communications and views possible. The decline in reading, therefore, equals a larger retreat from participation in public and cultural life. What is to be done? There is surely no single solution to the present problem, just as there is no single cause. The important thing now is to understand thatAmericacan no longer take active and devoted reading for granted. Readingis not a timeless, common ability. As more Americans lose this ability, our nation becomes less informed, active, and independent minded. These are not qualities that a free, inventive, or productive society can afford to lose.

Example Input: Article: When I was seven years old my mom was diagnosed with cancer. For this type of cancer the survival rate was low. My family was extremely upset and shocked. I was too young to understand. I had no idea that everyday with my mom had to be the absolute best because we didn't know if it would be our last. I didn't understand why everyone was suddenly taking time out of their busy lives to come over and sit on our couch. The doctors told us my mom might survive with surgery . But it could also kill her. She agreed to have it. The surgery was scheduled for the day after the Columbus Day. The day before the surgery I had off from school, and my mom planned the best day of my life. The day began with her waking me up saying, "Kate, I have a surprise for you. Come see." The surprise was a doll I had wanted for the longest time. Throughout the day, she told me everything that she thought I would need to know to grow up and be a good person; she told me to be the best I could be and that I would always make her proud. The day was filled with laughter. For the first time in a long time I could see she was happy. Really happy. The day passed and the next day, it was time for the surgery. There were no tears; I think I understood that I could lose my mom, because they did tell me she could die. We waited all day for news from the doctor. Everyone jumped when a door opened or anyone walked into the waiting room. Finally the doctor came in, and the news was what we had prayed for. I will never forget that day together, and how her illness pulled our family closer. I understand now how lucky we were. I truly appreciate life and honor my mom for being so strong.
