Article: When her five daughters were young, Helene An always told them that there was strength in unity . To show this, she held up one chopstick, representing oneperson. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up. Helene An and her family own a large restaurant business in California. However, when Helene and her husband Danny left their home in Vietnam in 1975, they didn't have much money. They moved their family to San Francisco. There they joined Danny's mother, Diana, who owned a small Italian sandwich shop. Soon afterwards, Helene and Diana changed the sandwich shop into a small Vietnamese restaurant. The five daughters helped in the restaurant when they were young. However, Helene did not want her daughters to always work in the family business because she thought it was too hard. Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elisabeth explains, "Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business." Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes more than $20 million each year. Although they began with a small restaurant, they had big dreams, and they worked together. Now they are a big success.

Article: I was working as an intern at my University's Museum of Natural history when I was an undergraduate in college. One day while working at the cash register in the gift shop, I saw an elderly couple come in with a little girl in a wheelchair. As I looked closer at this girl, I saw that she was kind of perched on her chair. I then realized that she had no arms or legs, just a head, neck and upper body. She was wearing a little white dress with red dots. As the couple wheeled her up to me I was looking down at the register. I turned my head toward the girl and gave her a wink , As I took the money from her grandparents, I looked back at the girl, who was giving me a nicest, largest smile I had ever seen. All of a sudden her handicap was gone and all I saw was this beautiful girl, whose smile just melted me and almost instantly gave me a completely new sense of what life is all about. She took me away from a poor, unhappy college student and brought me into her world; a world of smiles, love and warmth. That was 10 years ago. I'm a successful business person now and whenever I get down and think about the troubles of the world, I think about that little girl and the unforgettable lesson about life that she taught me.

Asnwer: C
Yes

Article: In summer, millions of people will head for the beach.And while the ocean can be a great place to swim and play, it may also be useful in another way.Some scientists think that waves could help make electricity. "Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland."There is certainly a lot of energy in waves." Scientists are working on using that energy to make electricity. Most waves are created when winds blow across the ocean."The winds start out by making little ripples in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, "Taylor said."Waves are one of nature's ways of picking up energy and then sending it off on a journey." When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine .The turbine can then power an electrical generator . The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland. The resource is huge.We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal. Oceans cover three quarters of the earth's surface.That would make wave power seem perfect for creating energy around the world.There are some _ , however. Jamie Taylor said that wave power still cost too much money.He said that its effects on animals in the sea were still unknown.Plus, wave power would get in the way of fishing and boat traffic. With more research, however, "many of these problems might be overcome," Taylor said."Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world.Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day." In the future, when you turn on a light switch, an ocean wave could be providing the electricity!
Question: Which of the following is NOT true?
Options: (A) Wave power costs too much money. (B) Wave energy creates the same amount of pollution as other energy sources. (C) Wave power affects fishing and boat traffic. (D) Wave power may affect marine animals.
Asnwer: B
Yes
