Article: Have you dreamed of traveling to cool places, meeting different people, and maybe picking up a language or two? No matter which country you live in, you can fly over the world's highest waterfalls in Venezuela, study in France or take dancing lessons in Ghana. Besides the excitement of traveling, there is another reason to study abroad. "Obviously, I learned the language and am now fluent, but perhaps what's more important was how much I learned about cultures, people, and myself." said Andrew, who studied in France. Christina studied in Caracas, Venezuela, a city of 10 million people and a huge change from her hometown of 35,000! Christina said she learned how to better speak for herself and her beliefs and to express herself in another language. What could make you more confident than that? Living away from home can also help you become adapted to the transition to college and adulthood. Matthew said that he returned from studying in Australia with confidence, and a real interest in international affairs. "After having gone abroad in high school, _ -- moving 560 miles from home didn't seem difficult at all after having lived thousands of miles away. " Speaking of college, improving your language skills might help you get into ideal colleges and even land future jobs. Colleges and employers know that studying abroad provides leadership skills in a world that needs much communication. Most of all, it's fun! You won't suffer from the general boredom while you're studying in a different learning environment. Question: According to Christina, studying abroad enables people to _ . Yes or no, is the answer "have confidence in themselves"?
Yes

Article: If a noisy neighbor is blasting music at all hours of the day and night, drowning out your phone conversations and interrupting your sleep, you can call the police. But what is a whale to do? Natural noise from waves, wind, rain and even earthquakes is common in oceans. Unfortunately, man-made noise from oil and gas drilling, sonar, and ships is also present. Low frequency noise has doubled off the California coast every decade since the nineteen sixties. The main reasons are ships' propellers . They not only generate continuous low frequency sound, some propellers cavitate , which means they create air bubbles that collapse, creating loud popping sounds. Whales use low frequency calls to communicate across thousands of miles of ocean. They are threatened by noise pollution because it can prevent them from contacting each other and from locating their foods. Endangered humpback and right whales, which use fibrous baleen to strain food from the water, are the most at risk. Scientists studying right whales off Canada's east coast have discovered that whales are sending louder calls through the water to make themselves heard. Because they invest more energy in making calls, they have less energy available for finding food and mating. Other scientists measuring whale calls against background noise pollution have discovered that right whales have lost about eighty percent of their normal communication area. This could seriously affect survival of this already threatened species. Scientists don't have badges and guns, but they are trying to correct the noise pollution problem. By tracking ships and marine mammals and understanding how noise travels, they are creating sound maps. They hope to get shipping lanes moved so that the noise pollution ships create will not overlap with areas most important to the whales. Question: What does the passage mainly talk about? Yes or no, is the answer "Noise pollution is affecting whales."?
No

Article: In 1961 Obama was born in Hawaii, US. His father was an African and his mother was a white American. He grew up in Indonesia and Hawaii. When Obama was 10 years old, he was one of the only three black students at his school in Hawaii. He felt very different from most other students. White girls wanted to touch his hair. A white boy even asked him what his father was. "I lied to them that my father was a Kenyan prince. But I kept asking myself who I am," said Obama. However, 37 years later, the boy made history. Obama became the first black president in US history. Obama's unusual background made him wonder who he was. He once turned to alcohol to help forget this question. With the help of his friends, Obama finally turned his life around at college. His hard work made him a star at Harvard. Later, he became the third black senator in US history. "Obama's success has made Martin Luther King's dream come true. That is: A man should not be judged by the colour of his skin, but by the content of his character," wrote ABC news. Question: Which of the following is TURE according to the passage? Yes or no, is the answer "Obama was once very depressed because of his unusual background."?
No

Article: The man who learned to fly It is publicly accepted that it was the Wright brothers that invented the plane, but actually George Cayley knew how to make a plane a century before the Wright brothers took off. If only he'd got the internal combustion engine to work. During the 18thand 19thcenturies, scientists and the public all believed that it was only impossible to fly using an artificial wing, but an act of silly deed to suggest that you could. This did not discourage the English gentleman scientist George Cayley, even though his contemporaries --- including his own son--- were embarrassed by his efforts. In 1799, Cayley carved a silver disc with one side bearing a design for the world's first aeroplane and the other illustrating the earliest published description of the aerodynamic forces on the wing that enable a plane to fly. His three--part essay Aerial Navigation, published in 1809 and 1810, was greeted with skepticism by his contemporaries. But Cayley "didn't give a rat's ass" about what they all thought, according to Richard Dyde of York University in Ontario, Canada, author of The Man Who Discovered Flight--- and with good reason. He had completed a series of experiments to back up his theories and "was convinced that everyone else was wrong". Cayley constructed increasingly excellent model flying machines, and finally invented a full-scale glider, which was flown in 1853 by his grandson, George. This pioneering work would prove inspirational to Orville and Wilbur Wright, who made the first controlled and sustained heavier-than-air human flight 50 years later. Their success was dependent on the recent invention of the internal combustion engine--- a device which Cayley, having realized its great importance, had spent many fruitless years trying to develop. Question: How many years later was George Cayley's glider flown after he first designed a plane? Yes or no, is the answer "Fifty-four years."?
Yes
