Scientists believe that someday one-man submarines will be as numerous as automobiles today. One says," One day soon, men will walk on the ocean floor as they do on the street. " Perhaps during your life time, people will travel, work and live under the sea. Ships carrying oil and articles of trade will move beneath the ocean. Passenger ships will be built to travel underwater, where storms cannot delay them or make people seasick. Special underwater ships will be designed for mining, fishing, and exploring unknown areas. For military use, there may be submarines that can fly and then dive underwater to approach the battle area without being seen. First, however, the human problems associated with living in the ocean will need to be studied in detail. Many of these problems are the same as the problems of living in outer space: pressure, lack of oxygen, and weightlessness. Already scientists have begun to study these problems. In 1963 and 1964 scientists and Navy divers lived and worked underwater for several days in two projects which were called Sealab I and Sealab II. The Sealab II experiment kept the scientists and divers 215 feet below the surface for thirty days, studying marine biology, temperature, pressure, currents, and ocean bottom geology. Many puzzling questions remain unanswered, however. Man's warm blood makes it difficult for him to live long in the sea without some kind of warmth. Can our blood be changed to fit new water surroundings? What will happen to our muscles if we live in the water very long? Will they become soft away from our usual land existence? Will bones become weak and our blood pressure change? Scientists are searching for answers. By studying plants and animals deep in the ocean, scientists may find a cure for some of our most serious human diseases. We may learn to use plants to increase our world food supply. Engineers may learn to use the power of the sea by building huge walls to catch the force of...

Read the article and select the best answer. Article: Luo Jingyu, 19, has four years of experience of running business. He is also a freshman in the arts department of Hubei University. Luo Jingyu is from an ordinary family. He said, "My parents told me if I wanted something I should make an effort to get it, so I earned pocket money by doing housework when I was little." The dream of running his own business grew in his heart. He said, "I want to be a successful person, like Alibaba's Ma Yun." When Luo was a junior student, he had the idea of selling lanterns when he saw many people flying Chinese lanterns in a square. Luo bought some lanterns from a store, but the sales were not as good as he had expected. Then he found another way to do business. He bought lanterns on the Internet at a very low price. Finally he easily made 5,000 yuan in two days. With a happy beginning, Luo planned to open a dress shop. "My parents didn't support me opening a dress shop, so I had to borrow 120,000 yuan for it." Although he did market research before starting, the business wasn't very good because his taste in fashion wasn't accepted by customers. The shop eventually closed down after half a year. After experiencing a big loss, he decided to do something he was familiar with --- selling painting tools. As a fine arts student, he knew the market. He convinced his friends to invest one million yuan in his shop. With a good business mind and a lot of effort, the sales of the shop reached six million yuan in a year. Even though Luo is rich, he uses a cheap cell phone and does not wear luxury clothes. He has a simple lifestyle. "It isn't easy to make money, so money should be used on something worthwhile," he said. Question: Why wasn't the dress shop successful? Options: A: He had to prepare for his exam. B: The dresses he bought weren't of high quality. C: Customers didn't accept his taste in fashion. D: He didn't have enough money to buy beautiful dresses.
