Read the following article and select the best answer. Article: Using tablet computers like Apple's iPad and Samsung's Galaxy Note just before bed can lead to a poor night's sleep, according to research. More and more people are taking their tablets to bed with them to surf the web, check Facebook or email before switching off the light. But researchers are warning that the blueish light their screens emit can stop users getting a good night's sleep. That is because this type of light mimics daylight, convincing the brain that it is still daytime. Blue light suppresses production of a brain chemical called melatonin, which helps us fall sleep. This is because our brains have evolved to be wakeful during daylight hours. By contrast, light which is more orange or red in tone does not reduce melatonin production, perhaps because our brains recognize it as a cue that the day is ending. Neurologists have known for years that staring at screens late in the evening can disrupt sleep. Researchers at the Lighting Research Centre, at the Rensselaer Polytechnic Institute in New York, are warning that looking at tablet displays for more than two hours "leads to a suppression of our natural melatonin levels as the devices emit optical radiation at short wavelengths" - in other words, they emit bluer light. They say: "Although turning off devices at night is the ultimate solution, it is recommended that if these devices are used at night displays are dimmed as much as possible and that the time spent on them before bed should be limited." They drew their conclusions after measuring melatonin levels in 13 volunteers, after they had spent time viewing iPads at full brightness at a distance of 10 inches, for two hours. Melatonin levels were significantly lower after they had done this, than they were after the volunteers had viewed their iPads for the same time, but while wearing orange glass goggles, which cut out the blue light. They wrote in the journal Applied Ergonomics that tablet makers could "tune the spectral power distribution of self-luminous devices " so that they... Question: Based on their findings, researchers have made the following suggestions except that _ . - Devices like iPads should be turned off at night. - Tablet makers should make improvements in devices. - Users should view iPads at full brightness instead of wearing orange glass goggles. - The time spent on screen before bed should be controlled.
Users should view iPads at full brightness instead of wearing orange glass goggles.

They were known as the Roaring Twenties, and the best place to experience this exciting time was New York City. But what was it really like? Prohibition In 1919, a new law in the US known as Prohibition made it illegal to buy and sell alcohol. But Prohibition didn't stop people drinking; it just drove the sale of strong alcoholic drink underground. Bootleggers waited off the coast of New York after dark and brought illegal alcohol into the city. Jazz Jazz was the music of New York in the 1920s. In fact, the decade is called Jazz Age. The best place to listen to this new form of music was the Cotton Club in Harlem. All the great jazz musicians played at the Cotton Club, including Louis Armstrong, Dizzy Gillespie and Duke Ellington. Also, in 1942 George Gershwin composed the jazz--influenced Rhapsody in Blue. The piece has been called "a musical portrait of New York" and was used by Woody Allen in his filmManhattan. Art Deco Art Deco was the most popular style of the 1920s, with bright colors and geometric designs; it can be seen in the art, architecture and inside designs of the period. New York is full of Art Deco buildings, but the most famous ones are the Chrysler Building (built between 1928 and 1930) and the Empire State Building (built between 1930 and 1931). The Great Depression On 29th October, 1929, the Roaring Twenties came to a dramatic end. On that day (known as "Black Tuesday"), the US stock market crashed, causing the Great Depression. The economic downturn lasted ten years and affected most of the Western world. Unemployment in America reached 25% and the country didn't recover until after World War II. Question: The 1920s is called _ . - Country Music Time - Jazz Age - Folk Music Age - Pop Age
Jazz Age

Q: Read the following article and select the best answer. Article: During his college years, Rogers spent his summer holidays at an Idaho logging camp . When Roy, the manager, had to leave for a few days, he put Rogers in charge. "What if the workers refuse to follow my orders?" Rogers asked. He thought of Tony, a worker who was always giving the other men a hard time. "Fire them," Roy said. Then, as if reading Rogers' mind, he added, "I suppose you want to fire Tony if you get the chance. I'd feel bad about that. Tony is the most reliable worker I've ever had. I know he complains a lot, but he comes first and leaves last. There has not been an accident on the hill where he works for eight years." Rogers took over the manager's job the next day. He went to Tony and spoke to him, "Tony, did you know that I'm in charge today?" Tony didn't show any respect or interest. "I was going to fire you because you once gave me a hard time, but I want you to know I'm not," he told Tony, adding what Roy had said. When Rogers finished, tears streamed down Tony's face. That day Tony worked harder than ever before --and he smiled for the first time! Rogers went back to school after that summer. Twelve years later he met Tony again. He was in charge of one of the largest logging companies in the West. Rogers asked him how he managed to become so successful. Tony replied, "If it were not for that time you spoke to me back in Idaho, I would not be myself today. That one minute changed my whole life." Have you got one minute to appreciate someone? It can make a difference for a lifetime. Question: Which of the following statements about Tony is TRUE? - He worked hard but he always complained. - He never showed respect to his co-workers. - Nobody liked Tony because of his bad temper. - He didn't care about his work.
