Read the following article and answer the question. Article: Betty and Harold have been married for years .But one thing still puzzles   old Harold .How is it that he can leave Betty and her friend Joan sitting on the sofa ,talking ,go out to a ballgame ,come back three and a half hours later ,and they're still sitting on the sofa ? Talking ? What in the world ,Harold wonders ,do they have to talk about ? Betty shrugs .Talk ? We're friends . Researching this matter called friendship ,psychologist Lillian Rubin spent two years interviewing more than two hundred women and men .No matter what their age ,their job ,their sex ,the results were completely clear :women have more friendships than men ,and the difference in the content and the quality of those friendships is "marked and unmistakable ." More than two -thirds of the single men Rubin interviewed could not name a best friend. Those who could were likely to name a woman .Yet three-quarters of the single women had no problem naming a best friend ,and almost always it was a woman .More married men than women named their wife/husband as a best friend ,most trusted person ,or the one they would turn to in time of emotional distress  ."Most women ,"says Rubin ,"identified   at least one ,usually more ,trusted friends to whom they could turn in a troubled moment ,and they spoke openly about the importance of these relationships in their lives ." "In general,"writes Rubin in her new book ,"women's friendships with each other rest on shared emotions and support ,but men's relationships are marked by shared activities." For the most part ,Rubin says ,interactions  between men are emotionally controlled -a good fit with the social requirements of "manly behavior ." "Even when a man is said to be a best friend ,"Rubin writes ,"the two share little about their innermost feelings .Whereas a woman's closest female friend might be the first to tell her to leave a failing marriage ,it wasn't unusual to hear a man say he didn't know his friend's marriage was in serious trouble until he appeared one night asking if he could sleep on... Question: What old Harold cannot understand or explain is the fact that  _  . Answer:

Read the following article and answer the question. Article: Frank Lloyd Wright probably is the greatest architect that the United States has ever produced. He was very gifted and had a natural ability to design buildings. His buildings were not only beautiful, but they were also practical and useful. They fit their purposes very well. Wright's churches, for example, make people feel like thinking and praying. His office buildings make people enjoy working, and his houses make people feel comfortable at home. However, Frank Lloyd Wright's beautiful, practical and useful buildings are not the only reason that he is famous. There is another reason. Frank Lloyd Wright is called the greatest American architect because he started an American style in architecture. Most of the architecture in the United States before Wright was really European, not American. Wright's buildings do not look like old European buildings. They have their own style. Wright's ideas about style are still used in the United States and in other parts of the world. The most important idea in Frank Lloyd Wright's Style of Architecture is that a building must fit its purpose and the land around it. His houses are often called "grass-land houses" because their lines are similar to the lines on the grassland. Both the lines of the grassland and the lines of Wright's house are parallel to the horizon, the place where earth and sky seem to meet. They are horizontal lines. Most European style houses, in contrast, have many vertical lines that form 90degangles with the horizon. Question: Frank Lloyd Wright's style in architecture was   _  . Answer:
****
A: not only limited to the U.S

Read the following article and answer the question. Article: A Brown University sleep researcher has some advice for people who run high schools: Don't start classes so early in the morning. It may not be that the students who at their desks are lazy. And it may not be that their parents have failed to enforce   bedtime. Instead, it may be that biologically these sleepyhead students aren't used to the early hour. "Maybe these kids are being asked to rise at the wrong time for their bodies," says Mary Carskadon, a professor looking at problem of adolescent    sleep at Brown's School of Medicine. Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level. she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns. Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought. Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at nigh and sleep later in the morning. But it's not just a matter of choice -their bodies are going through a change of sleep patterns. All of this makes the transfer from middle school to high school--which may start one hour earlier in the morning  ---- all the more difficult , Carskadon says. With their increased need for sleep and their biological clocks set on the "sleep late, rise late" pattern, adolescent are up against difficulties when it comes to trying to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body's way of saying. "I need a timeout." Question: Carskadon suggests that high schools should not start classes so early in the morning because    _   . Answer:
****
A: it is biologically difficult for students to rise early

Read the following article and answer the question. Article: One mile long runway can take people across the oceans, to reach every corner of the world. That's the magic power of airplanes as well as airports. Similar as most airports are, some do have their unique features. Lukla Airport Lukla Airport, is a small airport in the town of in the town of Lukla, eastern Nepal. A program titled Most Extreme Airports, rated the airport as the most dangerous airport in the world. The airport is popular because Lukla is the place where most people start the climb to Mount Everest Base Camp. High wind, cloud cover, and changing visibility often mean flights can be delayed or the airport closed. The airport's runway is accessible only to helicopters and small, fixed-wing, short-takeoff-and-landing aircraft. The runway is only 527m with an elevation of 2,845m. Princess Juliana International Airport Princess Juliana International Airport is in the country of Saint Maarten. The airport is perhaps best known for very low-altitude flyover landing approaches due to one end of its runway being extremely close to the shore and Maho Beach. The thrilling approaches and ease of access for shooting spectacular images make the airport one of the world's favorite places among plane spotters. Gibraltar Airport Gibraltar Airport serves the British overseas territory of Gibraltar, a tiny peninsula with an area of only 6.8 square kilometers. The lack of flat space there means the peninsula's only runway is bisected by its busiest road, the Winston Churchill Avenue that heads towards the land border with Spain. It is really scary that there is a four lane highway passing through the middle of the runway! Kai Tak Airport Kai Tak Airport was officially known as Hong Kong International Airport from 1954 to 6 July 1998, when it was closed and replaced by the new one at Chek Lap Kok, 30 kms to the west. With numerous skyscrapers and mountains located to the north and its only runway jutting out into Victoria Harbour, landing at the airport were dramatic to experience and technically demanding for...
