Article: Almost every day we come across situations in which we have to make decisions one way or another. Choice, we are given to believe, is a right. But for a good many people in the world, in rich and poor countries, choice is a luxury, something wonderful but hard to get, not a right. And for those who think they are exercising their right to make choices, the whole system is merely an illusion, a false idea created by companies and advertisers hoping to sell their products. The endless choice gives birth to anxiety in people's life. Buying something as basic as a coffee pot is not exactly simple. Easy access to a wide range of everyday goods leads to a sense of powerlessness in many people, ending in the shopper giving up and walking away, or just buying an unsuitable item that is not really wanted. Recent studies in England have shown that many electrical goods bought in almost every family are not really needed. More difficult decision-making is then either avoided or trusted into the hands of the professionals, lifestyle instructors, or advisors. It is not just the availability of the goods that is the problem, but the speed with which new types of products come on the market. Advances in design and production help quicken the process. Products also need to have a short lifespan so that the public can be persuaded to replace them within a short time. The typical example is computers, which are almost out-of-date once they are bought. This indeed makes selection a problem. Gone are the days when one could just walk with ease into a shop and buy one thing: no choice, no anxiety. Question: By using computers as an example, the author wants to prove _ . Yes or no, is the answer "products of the latest design flood the market"?
Yes

Article: Social networking websites are causing alarming changes in the brains of young users, a famous scientist has warned.Sites such as Facebook, Twitter and Bebo are said to shorten attention spans , encourage instant satisfaction and make children more self-centered. Warnings from neuroscientist Susan Greenfield will disturb the millions whose social lives depend on surfing their favorite websites each day.But they will strike a chord with parents and teachers who complain that many teenagers lack the ability to communicate or concentrate away from their screens. More than 150 million use Facebook to keep in touch with friends, share photographs and videos and post regular updates of their movements and thoughts.A further six million have signed up to Twitter, the "micro-blogging" service that lets users exchange text messages about themselves.But while the sites are popular and extremely profitable, a growing number of psychologists and neuroscientists believe they may be doing more harm than good. Baroness Tarot, an Oxford University neuroscientist believes repeated exposure could rewire the brain.Computer games and fast-paced TV shows were also a factor, she said."My fear is that these technologies are weakening the brain to the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and live for the moment." "I often wonder whether real conversation in real time may eventually give way to these easier and faster screen dialogues, in much the same way as killing and butchering an animal to eat has been replaced by the convenience of packages on the supermarket shelf," she said. Psychologists have also argued that digital technology is changing the way we think.They point out that students no longer need to plan their term papers before starting to write--thanks to word processors they can edit as they go along. A study by the Broadcaster Audience Board found teenagers now spend seven and a half hours a day in front of a screen.Educational psychologist...

Ques: Article: The ozone layer is a thin layer of gas around the earth. It forms a special "blanket" around the planet. This "blanket" protects the earth from dangerous rays produced by the sun. Without the ozone layer, the earth's climate could warm to dangerous levels. This increase in temperature would threaten our survival. Scientists recently have discovered a hole in the ozone layer above the Antarctica. Now there is great concern that this warning has started, endangering all life on the earth. What has destroyed part of the ozone layer? Scientists do not know for sure. They suspect that our popular spray cans have played a part in the damage. Many spray cans contain dangerous gases. These gases might have destroyed the ozone layer fifteen miles above the earth's surface, The chemicals used in refrigerators and air conditioners may contribute to the problem, too. Many scientists believe that the destruction of the ozone layer is a serious problem for people everywhere. Global warming could change weather patterns around the world. Farmers and ranchers could find it more and more difficult to produce enough food for the earth's people. If more of the sun's dangerous rays reached the earth, there also could be an increase in skin cancers. Some skin cancers might cause people to die. Although some scientists do not believe there is a serious danger, obviously no one wants to take any chance on such a possibility. Can scientists repair the hole in the ozone layer? They really don't know the answer to that question. Can people do anything to save the ozone layer that the earth still has? Scientists stress the need to limit the use of spray cans and other items that contain the dangerous gases. This will not be an easy task. People all over the world use these items. Solving the problem certainly will require commitment and cooperation from everyone. Question: Saving the ozone layer needs everyone's effort because _ . Yes or no, is the answer "people all over the world use items containing dangerous gases"?
Ans: No
