Q: Have you ever remembered something with your nose? Maybe the smell of hot dogs makes you think of being at a baseball game. Or the smell of barbequed meat reminds you of a night around a fire. Scientists know that smells can make people think of powerful memories. Wouldn't it be great to somehow save those memories?      _ is exactly what Mark Crames, a businessman making perfumes  , is trying to do. His company, Demeter Fragrance, makes more than 200 kinds of perfumes. "Imagine every smell in the world as a musical note," Crames said. "We try to join those notes to make a piece of beautiful music." He has made many perfumes and he got the idea from plays, storms and even animals.     Everyday smells mean different things to different people. "A perfume called Poison Ivy might make you think of sadness or surprise," Crames says. "But it could make another person think of a great time at summer camp."     Crames produces perfumes using a high-tech method called headspace technology. This month, Crames is making scent for Tootsie Roll and Junior Mints. Not every smell can be easily copied. "One of our most needed perfumes is a little dog's breath," he says. "But it is so chemically complicated   that it's very hard to get."     What scent would you like to bottle? A zoo? Or grandma's old house? Crames may be able to help you bring back your memories, so all you have to do is have a smell when you want to remember. Which part of a website can this passage come from? A) Fashion. B) Science.

Q: The first kind of air transportation was not a plane. It was a balloon. People traveled by balloon 100 years before there were planes or jet aircraft. Those early days of ballooning were exciting, but they were also dangerous. Sometimes the balloons fell suddenly. Sometimes they burned. However, the danger did not stop the balloonists. The first real balloon flight was in France in 1783. Two Frenchmen, the Montgolfier brothers, made a balloon. They filled a very large paper bag with hot air.  Hot air is lighter than cold air, so it goes up. The Montgolfier's hot air balloon went up 1,000 feet in the sky. Later that same year, two other Frenchmen ascended   in a basket under a balloon. They built a fire under the balloon to make the air hot. This made the balloon stay up in the air for a few hours. But their balloon was tied to the ground. So it could not go anywhere. The first free balloon flight was in December, 1783. The balloon flew for 25 minutes over Paris. It traveled about 5.5 miles. Flying a balloon is not like flying a plane. The balloon has no engine and therefore no power of its own. The wind directs the balloon. It goes where the wind blows. The pilot can control only the altitude of the balloon to find the right wind direction. That is how a good pilot controls where the balloons goes. Soon balloonists tried longer flights. A major event in the history of ballooning was the first long flight over water. In 1785, an American and a Frenchman flew over the English Channel. During the nineteenth century, ballooning became a popular sport. There were balloon races in Europe. Balloons were also used by scientists to study the air and by armies in wartime. After the airplane was invented, people lost interest in balloons. Planes were much faster and easier to control.  But some people today still like to go up in balloons. High up in the balloon basket, they find quietness. They have wonderful view of the world below. One way to control a balloon is to  _  . A) use the engine B) find the right wind direction C) ask the pilot D) not change altitude
A: B

Q: Bringing up children is hard work, and you are often to blame for any bad behavior of your children. If so, Judith Rich Harris has good news for you. Parents, she argues, have no important long -term effects on the development of the personality of their children. Far more important are their playground friends and neighborhood. Ms. Harris takes to hitting the assumption, which has dominated  developmental psychology for almost half a century. Ms. Harris's attack on the developmental psychologists' "nurture" argument looks likely to reinforce  doubts that the profession was already having. If parents matter, why is it that two adopted children, brought up in the same home, are no more similar in personality than two adopted children brought up in separate homes? Or that a pair of identical twins, brought up in the same home, are no more alike than a pair of identical twins brought up in different homes? Difficult as it is to track the clear effects of parental upbringing, it may be harder to measure the exact influence of the peer  group in childhood and adolescence. Ms. Harris points to how children from immigrant homes soon learn not to speak at school in the way their parents speak. But acquiring a language is surely a skill, rather than a characteristic of the sort developmental psychologists hunt for. Certainly it is different from growing up tensely or relaxed, or from learning to be honest or hard -working or generous. Easy though it may be to prove that parents have little impact on those qualities, it will be hard to prove that peers have vastly more. Moreover, mum and dad surely cannot be ignored completely. Young adults may, as Ms. Harris argues, be keen to appear like their peers. But even in those early years, parents have the power to open doors: they may choose the peers with whom their young associate, and pick that influential neighborhood. Moreover, most people suspect that they come to resemble their parents more in middle age. So the balance of influences is probably complicated. Even if... What does the author mean by saying parents are not completely off the look at the end of the passage? A) Parents should control the situation. B) Parents should give their way to children. C) Parents should spend more time on children. D) Parents should take on their responsibility.
