[Q]: Article: I was on vacation, and in my mind, vacation does not mean setting my hotel room alarm clock for 6 am. But when you're in Aruba and hoping to reserve a beachside palapa , that's exactly what you do. Tourists begin lining up at the crack of dawn to secure these umbrella-like wood structures that are covered with dried and woven palm leaves. They then place towels on chairs and call them theirs for the day, whether they remain there or not. I knew nothing of _ on my first day in Aruba. I saw an empty chair covered with a towel and took it. It was a big mistake. For many visitors, a week bathing in the sun is the only activity they wish to pursue. It sounded good to my girlfriend, Barbara, and me after Boston's awful winter. Six more inches of snow was predicted on the day we left. The sun, the sand, and the beach seemed just about right. Aruba's slogan is "One Happy Island", and it doesn't take long to understand why. Aruba is said to be on "island time". Translation: No one is in a rush to do anything. When in Aruba, you go with the flow, however slow and lazy that might be. Cooling trade winds, white sandy beaches, turquoise waters, and dazzling sunsets are all good reasons to visit. But this 20-mile island offers more than lazy days walking on the beach. There is amazing night life, casinos, golf, scuba diving , fine dining, shopping, and a great national park. But our first day was spent as you'd expect, swimming in the sea and enjoying cool drinks. Our drink of choice quickly became the Coco Loco. It's as refreshing as it sounds.

Options: (A) want to see the sunrise early (B) need to check out early (C) want to have fun longer (D) need to reserve a beachside palapa

[Q]: Article: Duke Ellington is known as one of the most important composers of his time, and his work has been enjoyed for more than 80 years by music lovers all over the world. During his lifetime Ellington turned musical sounds into many compositions, mostly in the style known as jazz. The Early Years Edward Kennedy Ellington was born in 1899 in Washington, D. C. It wasn't until Ellington was a teenager that his interest in music grew. He taught himself to play the piano by listening to local piano players. Sometime around 1916 Ellington began playing the piano at high school parties. Ellington realized that he enjoyed entertaining people with his music. He soon became a very popular musician, playing at parties and other events in the Washington area. Young adults seemed especially delighted by the modern pieces he composed. Success in New York In 1923, when Ellington was almost 24 years old, he joined The Washingtonians, a five-piece group of musicians in Washington, and became the group's leader in early 1924. In 1927 Ellington and his orchestra won an engagement at Harlem's famous Cotton Club. For the next three years, his orchestra played at the Cotton Club nearly every night. The Influence of the Cotton Club Working at the Cotton Club encouraged Ellington's creativity. Since the shows changed every six months, he was challenged by the need to continually develop new material. He had to compose a wide variety of music to accompany the various acts in the Cotton Club shows and to adapt that music to the strengths and weaknesses of the players in his orchestra. By 1928 the popular nightspot began radio broadcasts. From the broadcasts Ellington and his orchestra gained a national reputation. On the Road As Ellington's popularity increased, he realized that his orchestra could do well on concert tours. They left the Cotton Club in 1931 and toured America and Europe almost continually for the next 43 years. In addition to touring, Ellington made recordings and continued to compose music.

[Q]: Article: Tokyo University laboratory has developed a robot that never loses at the game of Rock Paper Scissors. That is because its visual processing abilities and fingers work together faster than any human brain. A video of the undefeated robot has been watched by more than 3 million viewers on YouTube since going online at the end of June. Tokyo University engineering professor Masatoshi Ishikawa has a good-natured response to frustrated human losers who accuse him of essentially creating a robot that cheats. "It is not cheating. Every one millisecond the image processor decides and recognizes the shape the human hand is going to make. And then the robot can make a winnable shape one millisecond later than a human being. Only one millisecond, but a human cannot see this difference because the human eye is very slow," explained Ishikawa. At the Ishikawa Oku Laboratory there has been amazing progress which shows the near perfect accuracy of robotics. Such as a robot that can catch a falling egg without breaking it, another one that can tie a knot, and a robot that may not be quite ready for the NBA, but is able to dribble a ball. In sports such as baseball and cricket, the misses outnumber(......)successes for even the most skilled athletes. That is not so in this award-winning school laboratory. For instance, an intelligent robot is the result of five years of research and a lot of trial and error. And the cost of just one finger on the robot is equal to that of a mini car. The technology obviously has uses beyond fun and games. Corporations are eager to take advantage of the lab's technology for industrial and other practical uses. And there is talk of applying it to assist disabled people and improve human capabilities.
Question: What brings the robot so much attention on the YouTube?
Options: (A) It never loses in the game against humans. (B) Its eyes and fingers can work at the same time. (C) It can do anything whatever people tell it to do. (D) It plays online games much better than any human.
