[EX Q]: Article: YOU probably think you know about London's problems. The people are unfriendly, it's way too expensive, and the food is terrible - so why do so many tourists flock there? London was named the world's most popular city between July and September 2013. It _ other world-famous cities such as New York and Paris, welcoming 4.9 million visitors, according to the UK Office for National Statistics. Amazingly, this was an increase of almost 19.5 percent on 2012 - the year when the Olympics happened in summer. So can London's success be explained? Well, maybe. As the English writer Samuel Johnson once said, "when a man is tired of London, he is tired of life". London life is often crazy and expensive, but if you can think of something, you can probably do it there. Anywhere in the city, you can often look around a great museum such as the British Museum, watch a concert at a historic venue like the Royal Albert Hall, or dance the night away in a cool nightclub such as Fabric. And it's not just about culture - there are also world-famous sporting venues around the city. Many tourists like to watch soccer matches at stadiums such as Chelsea's Stamford Bridge, Arsenal's Emirates Stadium, or Tottenham's White Hart Lane. Tourists even came to watch British tennis player Andy Murray's famous victory at the Wimbledon tennis tournament in 2013. Yes, but what about the food? Well, even if you don't like British food - and if you've never had real fish and chips, or a summer pudding, then perhaps you should wait until you've tried them - there is plenty of great food from all over the world available in London's many restaurants. London, like many of its buildings, has a long history, but also never lacks a vibrant pulse . All over the city, history and modernity come together to make it an essential place for tourists to discover.

[EX Q]: Article: I often write about the bad state of television these days, but recently my mom told me about a story she saw on 60 Minutesthat was inspiring, educational, and entertaining for the whole family. I went to the show's website to see for myself. My mom was right. At a time when even Barbara Walters says she's really bored with celebrities interviews, this one will not disappoint. It's the story of Derek Paravicini, a 30-year-old who was born three months early, physically disabled (he can't button his own shirt), blind, and severely autistic . Yet, through total luck and coincidence, his family discovered that Derek had a remarkable musical talent when he was three. Derek can hear any musical composition one time and play it perfectly on the piano. That's right. He only has to hear it once. Even more unbelievable, his brain, like a computer, can keep many songs that he can immediately repeat when asked. But his talent isn't limited to just learning things by heart. Derek is a true musical genius and artist who plays beautifully in a wide range of styles and can make his own music. With his talent, Derek has raised millions of dollars putting on charity concerts. He also donates his time to senior centers where he acts as a human jukebox machine, taking requests from senior citizens who haven't heard their favorite songs for decades. As it turns out, Derek loves people and his extraordinary talent has been the key to unlocking his personality and social development. If you want to inspire your family, pop some popcorn and sit everyone down to watch this excellent piece of journalism. If your kids are like mine, it will cause a great family discussion about the definition of "disability" and the extraordinary ability of the human brain and spirit. It may even give you the perfect answer the next time your child says he or she "can't" do something. Now that's priceless. Who says there's nothing good on TV?
Question: How does Derek help the elderly?
Options: (A) By buying them a jukebox machine. (B) By building senior centers for them. (C) By singing the old songs they ask for. (D) By playing the piano to raise money for them.

[EX Q]: Article: It was a sunny holiday Monday. Olivier Ferrante was cooking sausages on the barbecue and entertaining friends in his garden north of Paris when the phone rang. The call came from the BEA, France's air accidents investigation bureau , where the 38-year-old former football player and driver was an investigator. The news was grim. "An Airbus is missing over the Atlantic: we need you." As a safety investigator,Ferrante and his teams had participated, directly and indirectly,in the recovery of crashed planes from the Red Sea, the Black Sea,and every ocean. But this investigation would be his toughest ever: the plane had disappeared without a witness, or a trace on radar . At least eight ships and a dozen military aircraft gathered on the plane's last known position, about halfway between Brazil and Western Africa. After six days the aircraft's tail fin and 50 bodies were spotted on the surface and the first burning questions were answered. The plane wreckage and passenger injuries indicated the doomed Airbus was unbroken when it hit the water. It was not exploded apart by a bomb or lightning, now broken up by violent weather. Strangely, no mayday message had been sent by its pilots. Ferrante worked energetically with his team:collecting offers of help from around the world, consulting navy ministries and research organizations in France and elsewhere, and contracting suitable ships and high-tech equipment. He would not return home for another 29 days. His team used the Autonomous Underwater Vehicle(AUV) operated around the clock, searching about 400 square kilometers a day. But the race against time was lost and no signals were heard and no more wreckage was found. Day after day, the screen remained bare except for objects that turned out to be stones or garbage from ships. Stressed by media attention and painful meetings with victims' s,Ferrante went jogging one day to clear his head. Then he had an idea. He decided to look at what had happened to nine other planes that crashed after something abruptly went wrong while flying at high altitude. He found that none had traveled more than 30 km before hitting the sea; most covered less than half that distance. AUV operations continued but now they focused on a 30 km circle around the plane's last known position. On the ninth day of the new-strategy searching, after searching for 22 months, their hard work paid off finally. The first thing they saw was a woman's handbag. Next,they saw bits of twisted aircraft parts and a panel with "AF" painted on it. Without a doubt,this was the missing Aribus,lying 11 km northeast of its last known position, but nobody felt much like cheering the discovery. "The screen also exposed well-preserved human bodies,and for some of us they were hard to look at," says Ferrante.
