Article: The United States covers a large part of the North American continent. Its neighbours are Canada to the north and Mexico to the south. Although the United States is a big country, it is not the largest in the world. In 1964, its population was over 185,000,000. When this land first became a nation, after winning its independence from England, it had thirteen states. Each of the states was represented on the American flag by a star. All these states were in the eastern part of the continent. As the nation grew toward the west, new states were added and new stars appeared on the flag. For a long time, there were 48 stars. In 1959, however, two more stars were added to the flag, representing the new states of Alaska and Hawaii. Indians were the first people of the land which is now the United States. There are still many thousands of Indians now living in all parts of the country. Sometimes it is said that the Indians are "the only real Americans". Most Americans come from all over the world. Those who came first in greatest numbers to make their homes on the eastern coast of North America were mostly from England. It is for that reason that the official language of the United States is English and that its culture and customs are more like those of England than those of any other country in the world. Question: Why is English the official language of America? Yes or no, is the answer "Most of the people who first settled in America were from England."?
No

Article: New York City plans to put a ban on the sale of large sodas and other sugary drinks at restaurants, movie theaters and street carts, in an effort to fight rising obesity. The ban would affect almost all the popular sugary drinks found in fast-food restaurants and even sports centers, from energy drinks to pre-sweetened iced teas. The sale of any cup or bottle of sweetened drink larger than 16 ounces would be forbidden under the first-in-the- nation plan. The measure would not apply to diet sodas, fruit juices, zero-calorie Vitamin Waters, dairy-based drinks like milkshakes , or alcoholic drinks; it would not expand to drinks sold in grocery stores or convenience stores. Stefan Friedman, spokesman for the New York City Beverage Association, criticized the city's plan, saying it turns focus away from the hard work that needs to be done on this front. Kelly Brownell, director of the Rudd Center for Food Policy and Obesity at Yale University, said he believes the ban would be effective. "It is not right to put all the blame for obesity on sugar drinks, but they are strongly connected with this rise in obesity over the last 30 years." Dr. Farley, the health commissioner, said the city had seen higher obesity rates in neighborhoods where soda consumption was more common. City officials said they believe it will finally prove popular and push governments around the U.S. to follow similar rules. Mr. Bloomberg has introduced a series of rules in his term of office, including bans on smoking in restaurants and parks, a ban on trans fat in restaurant food and a requirement for health inspection grades to be posted in restaurant windows. Because of the measures, the mayor was laughed at as Nanny Bloomberg, by those who view the bans as threats to personal freedom. But many of the measures adopted in New York have become models for other cities, including bans on smoking and trans fat, as well as the use of graphic advertising to fight smoking and soda consumption, and the demand that restaurants post calories contents... Question: What's the best title for the passage? Yes or no, is the answer "New York plans to ban sale of big sizes of sugary drinks."?
No

Article: The Chinese Antarctica expedition returned to Shanghai on March 20 following a month living on the ice. It was the first time Chinese scientists had visited the Amery Ice Shelf--the longest ice shelf in the world. The team collected ice samples and data on temperatures, which are necessary for research on global warming. So far, about 27 countries have visited Antarctica for scientific research. Although the living conditions are very hard, many scientists have to stay there for long periods of time. So, how do they manage their lives on the ice? Well, during the summer, the temperature in Antarctica reaches about-20degC. It falls to about-60degCin winter. So, even if there are 24 hours of sunshine, scientists must keep wearing all the correct clothes to protect them from the cold. These clothes include jeans, running shoes, jackets, long underwears, boots and woolen socks. Although highly technical clothing provides much protection against the extreme cold, scientists often need to go outside when there is an icy wind blowing and the temperature is-30degC. Natural protection such as facial hair can also help. "That's why many researchers wear a beard. It really does keep you warm,"says German explorer Arved Fuchs. Usually, the polar researchers have good meals. Some even have feasts on holidays like Christmas and New Year's Day. Vegetables are always welcome and usually finished the quickest. Life on the ice means living with other researchers in tight living space. Most people sleep in dorm style rooms. More remote field camps use separate tents. So, at least some researchers don't have to _ annoying snorers . But what do they do for fun in their spare time? There are actually a lot of things they can do. They watch movies, read tons of books, listen to music, have saunas ,paint and ski. Some female researchers might even do some knitting. It is important for a polar researcher to be in good physical condition. They can be required to climb to heights of more than 3, 000 meters. And the Antarctic... Question: Why do some polar researchers wear beards? Because _ . Yes or no, is the answer "beards are helpful to keep warm"?

Article: Nearly a quarter-century after a German boy threw a message in a bottle off a ship in the Baltic Sea, he's received an answer. A 13-year-old Russian, Daniil Korotkikh, was walking with his parents on a beach when he saw something lying in the sand. "I saw that bottle and it looked interesting," Korotkikh told The Associated Press on Tuesday. "it looked like a German beer bottle and there was a message inside. " It said, "My name is Frank, and I'm five years old. My dad and I are traveling on a ship to Denmark. If you find this letter, please write back to me, and I will write back to you." The letter, dated 1987, included an address in the town of Coesfeld. The boy in the letter, Frank Uesbeck, is now 29. His parents still live at the letter's address. The Russian boy and the German man met each other earlier this month through an internet video link. The Russian boy said he did not believe that the bottle actually spent 24 years in the sea. He believed it had been hidden under the sand where he found it for a long time. Uesbeck was especially happy that he was able to have a positive effect on a life of a young person far away from Germany. "It's really a wonderful story," he said. "And who knows? Perhaps one day we will actually be able to arrange a meeting in person. " Question: What is this passage mainly about? Yes or no, is the answer "Message in a bottle."?
