Article: More than a century ago, the composer and bandleader John Philip Sousa warned that technology would destroy music, who said, "These talking machines are going to ruin the artistic development of music in this country. When I was a boy ... in front of every house in the summer evenings you would find young people together singing the songs of the day or the old songs. Today you hear these terrible machines going night and day. We will not have a vocal cord left." Music has greatly changed in the past hundred years, which has been everywhere in our world: rivers of digital melody flow on the Internet or on disc; MP3 players with forty thousand songs can be put in a back pocket or a purse. Yet, for most of us, music is no longer something we do ourselves, or even watch other people do in front of us. It has become a radically virtual medium, an art without a face. Ever since Edison invented the phonograph cylinder , people have been assessing what the medium of recording has done for and to the art of music. Sousa was a spokesman for the party of doom; in the opposite corner are the utopians , who argue that technology has not imprisoned music but liberated it. Before Edison came along, Beethoven's symphonies could be heard only in select concert halls. Now the recordings carry the man from Bonn to the corners of the earth. Glenn Gould, after renouncing live performance in 1964, predicted that within the century the public concert would disappear into the electronic air. Having discovered much of my favorite music through LPs and CDs, I am not about to join Sousa's party. Modern urban environments are often so soulless or ugly that I'm grateful for the humanizing touch of electronic sound. But neither can I accept Gould's slashing futurism. I want to be aware of technology's effects, positive and negative. Fortunately, scholars and critics have been methodically exploring this _ for many decades, trying to figure out exactly what happens when we listen to music with no musicians in the room.

Article: A Battery's Nightmare Portable electronics that can be carried about easily are only as good as their batteries and, let's face it, batteries aren't very good, especially when compared with, say, petrol, which packs 100 times a battery's energy into an equal space. That's why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go. The engine---about the size of a ten-cent coin---starts with a combustion chamber that burns hydrogen. Its tiny parts are etched onto silicon wafers in the same manner that computer parts are etched onto integrated circuits . The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply. But the _ in all this nice detail is efficiency. Tiny engine parts don't always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine's designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine. The scientists' goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren't likely until at least the end of the next ten years.

Article: Many of today's parents fondly remember childhood days spent playing outdoors. When children make mud pies and observe ants, it may seem like just fun and games, but the truth is the outdoor play is an important part of growing up healthily. The National Association for the Education of Young Children reports that outdoor play reduces (make...less) stress and restlessness in children and improves their attention. Outdoor play is the perfect way to fight against the childhood's obesity(being fat).Research shows that children who play outdoors are more fit and thin, according to the National Center for Physical Development and Outdoor Play. Children who spend time outside on a regular basis also have healthier immune systems. And playing outdoors is a good way to get enough vitamin D. Playing outside enables children to relax , reduces tension and helps them solve problems. When children play outdoors, they learn to share and cooperate (work together) with one another. Kids who feel confident outdoors are likely to become able clever adults. The outdoors is a giant laboratory for learning that improves creative thinking and problem solving. Researchers have found that children learn best when their body, mind and spirit are involved , and this appears in outdoor play. Outside activities develop all five senses, which create a powerful learning environment. The outdoors also lets children have the chance to explore , experiment, form questions and create their own ideas about how the world works. Although there are the many advantages of outdoor play, time spent outside has been reduced for many of today's children. Kids today spend much more time in front of electronic media than children a generation ago. The lack of outdoor play is tied to the childhood widespread obesity. And experts predict that the situation is so serious that this generation will have much trouble when they grow up. To get kids involved with the outdoors, encourage them to collect rocks, fly kites, climb trees, garden, camp, swim, go fishing, watch birds and butterflies or play games with other children.
Question: Why don't the children play outdoors nowadays?
Options: (A) Because their parents prevent them from going out. (B) Because they spent time on computers and so on. (C) Because their parents want to make them indoors. (D) Because they do not know what to do outsides.
Asnwer: A
answer:
No
