Q: Read the article and select the best answer. Article: Beyond two or three days, the world's best weather forecasts are doubtful, and beyond six or seven they are worthless. The Butterfly Effect is the reason. For small pieces of weather--to a global forecaster, small can mean thunderstorms and blizzards --any prediction becomes worse rapidly. Errors and uncertainties increase, from dust devils and storms up to continent-size eddies that only satellites can see. The modern weather models work with net-like points sixty miles apart, and even so, some starting data have to be guessed, since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart, rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature, pressure, humidity , and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02, then 12.03... the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations that the computer will not know about. By 12.01, those fluctuations will already have created small errors one foot away. Soon the errors will have added to the ten-foot scale, and so on up to the size of the globe. Question: Our computer will not be able to know about fluctuations because _ . Options: A: the sensors are not good enough B: they are hidden by the spaces between the sensors C: they are too far away D: they move very fast
A: B

Q: Read the article and select the best answer. Article: Living and dealing with kids can be a difficult job these days, but living and dealing with parents can be even more complex. If I have learned anything in my 16 years, it is that communication is very important. With any relationship, you need to let other people know how you are feeling. If you are not able to communicate, you drift apart . When you are mad at your parents, or anyone else, not talking to them doesn't solve anything. Communication begins with the concerns of others. It means that you can't just come home from school, go up to your room and ignore everyone. To keep a good relationship, you must keep communication, even if it's just by writing a note. When dealing with parents, you always have to make them feel good about how they are doing as a parent. If you are trying to make them see something as you see it, tell them that you'll listen to what they have to say, but ask them politely to listen to you. Yelling or walking away only makes the situation worse. This is an example: one night, Sophie went to a street party with her friends. She knew she had to be home by midnight after the fireworks, but she didn't. She was late getting home. Her parents were mad at first, not giving Sophie a chance to explain why she was late. Later, they kept calm and listened to her. Communication is the key factor here. If Sophie's parents had not been willing to listen, Sophie would have been in a lot of trouble. Question: In the writer's view, dealing with parents is _ . Options: A: more difficult B: easier C: more uninteresting D: more interesting
A: A

Q: Read the article and select the best answer. Article: His name is James,but people call him Rocky.The name fits.He's big,over six feet tall,and he's tough when he needs to be.James "Rocky" Robinson lives and works in New York City's BedfordStuyvesant district,one of the poorest and most dangerous neighborhoods in the United States.Yet it is here in BedStuy that he is saving lives and reviving a community. In 1966,when Rocky was twentysix years old,his sevenyearold niece was struck by a car on the street of BedStuy.Had someone at the scene known first aid or CPR,she might have lived.But by the time she reached a hospital,she was dead. His niece's unnecessary death was one reason why Rocky became a paramedic .Working for the Emergency Medical Service of New York City,he realized that more than half the city's emergency calls came from highcrime areas.According to Rocky,residents of crimeplagued minority neighborhoods like BedStuy sometimes had to wait as long as 26 minutes after calling 911 for an ambulance while calls in richer white communities were answered _ . Rocky decided to find out more about the problem.His research showed that the richer communities had organized their own ambulance corps to improve city services because the city was overwhelmed with calls."If that's the key to success,"he told his friend and EMT (Emergency Medical Technician) colleague,Joe Perez,"we'll start our own corps in BedStuy!" In 1988,Rocky had no idea that he and Joe would be attempting to establish the first minorityrun ambulance service in the country,or just how creative he would have to be to overcome the difficulty.The pair's first challenge was to find a location for the headquarters.They took over an abandoned building that was commonly used by drug dealers.Because there was no electricity or running water (except for the leaks in the roof),the two men worked during daylight hours.They used a twoway radio to receive emergency calls. Although they could make do with their new headquarters,Rocky and Joe still lacked the most important component of an ambulance... Question: James' sevenyearold niece would have been saved if _ . Options: A: she had been sent to a better hospital B: she had got first aid and arrived in hospital earlier C: James had been at the spot D: emergency calls had been available in the area
A: B
