Article: My first performance in front of an audience was coming up soon. I tried as hard as I could to remain calm, but my heart was racing. I stared down at my sweat-covered, shaking hands. I looked up again at the audience, realizing that these were real people. They were not just my mum and dad, who would say, "Good job!" even if I messed up the entire piece. What if I had the wrong music? What if I played the wrong notes? As it turned out, I was never able to answer these questions because the spotlight was waiting for me. I grasped my hands tightly together, drying off the sweat. Slowly I walked to the mud-brown piano in the center of the room. It contained 88 demanding keys, which were waiting impatiently to be played. I swallowed the golf-ball-sized lump in my throat and sat down. Slowly, I opened the music. Next, I rested my still shaking hands on the ivory keys. As my fingers played across the keys, I was becoming more unsure of my preparation for this moment. But the memory of my years of training came flooding back. I knew that I had practiced this piece so many times that I could play it backwards if requested. Although at one point I accidentally played two keys instead of the intended one, I continued to move my fingers automatically . My eyes burned holes into (were fixed on) the pages in front of me. There was no way that I was going to lose my concentration. To keep this to myself, I leaned forward and focused carefully on the music. When I came to the end of the page, a warning went off inside my head: DON'T MAKE A MISTAKE WHEN YOU TURN THE PAGE! Needless to say, I obeyed myself with all my heart and mind. And, proud of my "page-turning" feat , I finished the rest of the piece without making a single mistake. After the final note died away, a celebration went into action inside my head. I had finished. I had mastered the impossible. Question: What did the author feel about her performance? Yes or no, is the answer "She thought it was very difficult but successful."?
Yes

Article: Surface Exploration. Robots make great explorers on planets,moons,and other landing areas. Aside from earth,just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient for humans to breathe,making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand .Plus there would be complications with radiation,weather,and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions. Data Collection. Robots are designed for collecting scientific data. Robots are also able to perform many tasks at a time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals,analyzing ground samples,and finding water are all performed much quicker and more accurately by robots. Cost Effective. The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans,but also enough food and water to keep them alive for the duration of the trip. Moreover,robots have no problems working for hours on end. Robots never complain,they don't require food or water,and they never need a bathroom break. Space Travel. Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are the Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history. Question: Which column could the passage come from?

Article: The triathlon promises to be one of the most popular Olympic sports.Recently it has drawn huge crowds attracted by athletes swimming 1,500m,cycling 40km,then running 10km without stopping.But what makes an attractive 17yearold girl give up everything for the doubtful pleasure it offers? Melanie Sears has not yet learnt those oftenrepeated phrases about personal satisfaction,mental challenge and higher targets that most athletes use when asked similar questions."You swim for 1,500m,then run out of the water and jump on your bike,still wet.Of course,then you freeze.When the 40km cycle ride is over,you have to run 10km,which is a long way when you're feeling exhausted.But it's great fun,and all worth it in the end," she says. Melanie entered her first triathlon at 14 and she won the junior section.Full of confidence,she entered the National Championships,and although she had the second fastest swim and the fastest run,she came nowhere."I was following this man and suddenly we came to the sea.We realised then that we had gone wrong.I ended up cycling 20 kilometres too far.I cried all the way through the running." But she did not give up and was determined that she never will."Sometimes I wish I could stop,because then the pain would be over,but I am afraid that if I let myself stop just once,I would be tempted to do it again."Such doggedness draws admiration from Steve Trew,the sport's director of coaching."I've just been testing her fitness," he says, "and she worked so hard on the running machine that it finally threw her off and into a wall.She had given it everything,and she just kept on." Melanie was top junior in this year's European Triathlon Championships,finishing 13th."I was almost as good as the top three in swimming and running,but much slower in cycling.That's why I'm working very hard at it." She is trying to talk her longsuffering parents,who will carry the PS1,300 cost of her trip to New Zealand for this year's world championships,into buying a PS2,000 bike,so she can try 25km and 100km races... Question: How does Melanie differ from other athletes,according to the writer? Yes or no, is the answer "She expresses herself differently."?
No
