Whether it is Mozart or Miley, your choice of music could determine whether you will perform well at your job. A new study suggests that listening to music in the office improves the speed and accuracy of tasks such as data entry, proofreading and problem solving. In an officebased experiment, 88 per cent of participants were found to produce their most accurate work when listening to music. The study also found that 81 per cent completed their work fastest when music was played. And it matters what type of music you listen to. For instance, if you're doing your tax returns, then classical music is the most effective as it improves maths skills. Listening to Jessie J or Justin Bieber could also improve your speed, with 58 per cent of participants completing data entry tasks faster while listening to pop songs. During proofreading, dance music, such as David Guetta, had the biggest positive impact with participants increasing their speed by 20 per cent compared to tests undertaken with no music at all. Dance music also had a positive effect on spellchecking with a 75 per cent pass rate compared to 68 per cent when no music was played at all. The research, undertaken by Brightonbased Mindlab International, suggests that silent offices may be the least productive. The Music Works experiment revealed a positive correlation between music and productivity. Overall, it showed that when listening to music, nine out of ten people performed better, said Dr David Lewis, chairman of Mindlab International. The result of the experiment showed that when music was played,   _  . A) 88% of people worked faster B) 81% of people did their most accurate work C) 90% of people worked better D) 75% of people completed data entry task faster

Harry Houdini was one of the greatest American entertainers in the theater this century. He was a man famous for his escapes from prison cells, from wooden boxes floating in rivers, from locked tanks full of water. He appeared in theaters all over Europe and America. Crowds came to see the great Houdini and his "magic" tricks. Of course, his secret was not magic or supernatural power. It was simply strength. He had the ability to move his toes as well as he moved his fingers. He could move his body into almost any position he wanted. Houdini started working in the entertainment world when he was 17, in 1891. He and his brother Theo performed card tricks in clubs in New York. They called themselves the Houdini Brothers. When Harry married in 1894, he and his wife Bess worked together as magician and assistant. But for a long time they were not very successful. Then Harry performed his first prison escape in Chicago in 1898. Harry persuaded a detective to let him try to escape from the prison, and he invited the local newspapermen to watch. It was the publicity   that came from this that started Harry Houdini's success. Harry had fingers trained to escape from handcuffs and toes trained to escape from ankle chains. But his biggest secret was how he unlocked the prison doors. Every time he went into the prison cell, Bess gave him a kiss for good luck and a small skeleton key, which is a key that fits many locks. She passed it quickly from her mouth to his. Harry used these prison escapes to build his fame. He arranged to escape from the local prison of every town he visited. In the afternoon, the people of the town would read about it in their local newspapers, and in the evening every seat in the local theater would be full. What was the result? Worldwide fame and a name remembered today. It can be inferred from the passage that Houdini became famous   _   . A) in 1894 B) before he married C) at the age of 17 D) when he was 24
