[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?

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: 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: It is amazing to note that the Internet is still such a new device, and yet it is one of the fastest and most powerful media tools. But think about it for a moment. On the Internet, a big online company can be run by two guys out of their garage. So it is only reasonable that people shopping on the Net would be a little _ of the security levels. Internet giants such as Microsoft knew consumer confidence was the key to getting virtual shopping off the ground, and they work hard to make people feel safe to shop online. Credit card companies, too, quickly saw the potential for Internet shopping, and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases, many credit card companies will happily refund your money and then set their claws on the company that wronged you. Now that's buying power! There are other bonuses for online shoppers, of course. No line-ups, for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won't get them what they want. When shopping online, consumers can sit down, have a coffee, and wear their slippers, not have to worry about their hair or parking and just click through sale after sale. Comparison shopping couldn't be any easier. And thanks to courier companies getting in on the act, you never need wait longer than a day or two to get those all important purchases delivered right to your door. No wonder so many companies are shaking their heads at traditional advertising and instead looking to the "virtual" world to attract online shoppers.
Question: _ leads to consumers' trust in online shopping.
Options: (A) Shopping law (B) Shopping convenience (C) Internet access (D) Shopping security
