Article: Could cities that float   on the sea solve the problems caused by floods and provide food for the world? Some scientists think so. The idea is already being tested and they believe that floating citied will provide more homes for a growing population, without having to use land needed to grow food. And they believe floating areas will allow more food to be grown, so that no one in the world is hungry. In some places, cities that float on the sea are already being planned, A company in the Netherlands called DeltaSync thinks that sea cities will save the world, with more than one in ten people living in them. They say sea cities solve many of the problems the world faces in the 21st century, like not having enough land , more and more people needing homes, fossil fuels   running low and the increasingly serious problems caused by floods. DeltaSync says building in the desert   is not possible because there is no enough water and that developing ways for people to live in space is still too expensive. So they believe the answer is our oceans, which cover over two thirds of the Earth's surface. Their plans for floating areas include using algae   to produce fuel and food. More than a quarter of the land in the Netherlands already lies underwater and scientists there have spent years trying to find ways to deal with it. In the city of Rotterdam they already have floating homes. Bart Roeffen from DeltaSync says: "We have plans for neighbourhoods including roads and, in the end, I believe we can build floating cities on the sea." 
 Question: DeltaSync is a company that wants to build cities   _  . 
 Options: (A) on land (B) in space (C) on the sea (D) in the desert

Article: If you want to see climate change, head north and keep going until you run out of globe. That is easier said than done. The Arctic   is home to few people and covered in ice much of the year. But those who make their way to the icy seas of the Arctic Ocean will see a part of the planet that is warming and changing faster than anywhere else. In September, scientists announced at the National Snow and Ice Data   Center that Arctic summer sea ice had fallen to its second lowest level since 1979, and probably long before that. The Arctic has lost an area of ice greater than the area of all U.S. states east of the Mississippi River. And what ice remains appears to be getting thinner and weaker. Nick Toberg and Till Wagner are polar ice scientists who are doing sea ice fieldwork. "There is plenty of data to suggest that the ice is becoming thinner as well as smaller in area," they say. The changes happening in the Arctic are a warning for the entire world .  As polar expert Walt Meier puts it, " _  Some scientists worry that Arctic sea ice may be going from a downward spiral   to a "death spiral", one from which there is no escape. As more ice melts  , more dark open water appears. The darkness absorbs   more heat, which speeds up the pace of melting. Until recently, many scientists thought it might take until the end of the century for the North Pole to become completely ice free during the summer. Now some believe it could happen by 2030 or even earlier. "The melting is happening faster in the real world than it has in the models," says Nick Toberg. 
 Question: Nick Toberg may agree that   _  . 
 Options: (A) the ice in the North Pole will stop melting (B) the ice in the North Pole is melting faster than expected (C) the ice in the North Pole will melt before 2030 or even earlier (D) the ice in the North Pole will not disappear until the end of the century

Article: Oprah Winfrey has come a long way from her poor childhood home in a small Mississippi town. She was an unwanted child whose parents never married. She was brought up on her grandmother's farm. The possibility that she would become rich and famous was slim. Oprah's mother left her child in her mother's care, so she could go to work in Milwaukee, Wisconsin. It was a strict and difficult life for Oprah. But it also led the way for her future. She was a highly intelligent child. By the age of three, she had learned to read and write. She also made her first public appearance at that age. Oprah's intelligence was resented   by other children of her age. They called her unkind names and pushed her away. Oprah felt very isolated and unwanted. It made her feel worse that she didn't live with her mother and father. She felt that no one loved her. This made her angry and rebellious  . These feelings brought her much trouble as she was growing up. She often behaved badly, causing her grandmother to punish her. By the age of seven, she was too much for her grandmother to discipline. Then Oprah went to live with her mother, Vernita, who worked very hard as a housekeeper in Milwaukee. It was hard for her to work and take care of her bright, troublesome child. They lived in poverty in a small apartment. Oprah took out all her angry feelings on her mother. When Oprah was eight, Vernita sent her to live with her father and stepmother in Nashville, Tennessee. But she moved again a few months later when Vernita married a man with two children. Vernita wanted Oprah to be with her and her new family. Unfortunately, she felt she didn't belong with them. She believed she wasn't loved by anyone. Her angry and frustration grew stronger. She struck back by misbehaving and running away from home. Her parents found her impossible to discipline. When she was 14, they tried to send her to a special center for troubled girls. But there was no room for her. So Vernita sent Oprah back to live with her father. Vernon Winfrey was by then a successful businessman and family man. He took one look at his daughter and knew she needed love, guidance and discipline. He gave her all three. It was a turning point in Oprah's life. He was strict about his daughter's education. He gave her homework in addition to her schoolwork. She was allowed to watch only one hour of television a day. She became an A student and a popular girl in her class. Oprah watched Barbara Walters, a famous journalist, and decided that was what she wanted to be. When she was still in high school, she got a part-time job reading news on the radio. In her senior year she won a beauty contest and a four-year scholarship to Tennessee State University. While still in college she was offered a job as a news broadcaster at a local television station. She was the first female and the first African-American newscaster in Nashville. She was promoted to anchor, the most important position on the news team, while still a senior. After Oprah graduated she got a job with a Baltimore news station. But she soon realized that broadcasting news wasn't enough for her. She had to let her personality shine through. She wanted to show emotion when she told a story, not just report it. Meanwhile the station managers were thinking the same way. They removed her from the anchor spot and wondered what to do with her. Finally they put her on an early morning talk show called People Are Talking. No one knew what to expect. The show was a great success. In a very short time, the managers and Oprah all knew what she was born to do. She was everything a talk show host should be. She was so successful that she got a show with a bigger station in Chicago. In 1985 the show was changed to The Oprah Winfrey Show. It was broadcast nationally and soon became the most popular talk show on television. By the age of 35, Oprah Winfrey was one of the most famous celebrities in America.
