But ever since then the little boy has set about learning how to make money by selling drinks, delivering newspaper and buying stocks. The American had already earned $9,000 (equal to $90,000 today) by the time he graduated from the high school. And this month the 78-year-old, who earned his fortune by making a lot of sound investment in the stock market, took the place of Microsoft founder, Bill Gates, as the world's richest man. Gates' worth declined $1.5 billion to $55.5 billion in 33 days after the recent financial storm, according to Forbes Magazine. Buffett, the only son of a stockbroker, was ready to think outside the box to develop his business from a very early age. At 8, he went to golf courses collecting and selling the used balls. At 11 when he sold soda pop door-to-door with a friend, the pair collected lids on streets to judge which flavor was the most popular.

With his paper delivery savings, Buffett bought 162,000 square meters of farmland and collected rent. Young Buffett stepped into the stock market at 11 but earned only $5. The experience taught him one of the virtues in investing patience. After graduating from university, Buffett started his venture with stocks with his childhood earnings and money from friends. He researched the stocks and just bought those of solid companies that were undervalued and inexpensive at the time. By sticking to companies such as American Express and Coca-Cola, Buffett has become rich. "Learning is important to Buffett's success. He is a learning machine who can spend his entire day reading.

Question: Read the following article and answer the question. Article: Last year college students in America spent an estimated $700 on textbooks on average. The National Association of College Stores reported more than five billion dollars in sales of textbooks and course materials. The association spokesman Charles Schmidt says electronic textbooks now just make up 2%~3% of sales. But he says that is expected to reach 10%~15% by 2012. Online versions are now available for many of the most popular college textbooks. An etextbook can cost half the price of a new print textbook. But students usually lose access to them after the end of the term. And the books cannot be placed on more than one device ,so they are not easy to share. So what do students think of etextbooks?Administrators at Northwest Missouri State University wanted to find it out. Earlier this year they tested them with 500 students in 20 classes. The university is unusual. It provides laptop computers for all 7,000 of its fulltime students. It does not require students to buy their textbooks either. They rent them to save money. The school aims to save even more by moving to etextbooks. The students in the survey reported that downloading the books from the Internet was easy. They liked the idea of carrying lighter backpacks. And 56% said they were better able to find information. But most found that using etextbooks did not change their study habits. And 60% felt they read more when they were reading on paper. In all,almost half the students said they still liked physical textbooks better. But the survey found that cost could be a big influence.55% said they would choose etextbooks if using them meant their textbook rental fee would not increase. Roger Von Holzen heads the Center for Information Technology in Education at Northwest Missouri State University. He tells us that administrators are disappointed with the etextbooks now available because the majority are not interactive . He thinks growth will come when more digital books include video,activities,games and other ways to interact with the information....

Question: Read the following article and answer the question. Article: People often ask me how, as a man, I became so devoted to improving the quality of women's lives. It wasn't until age forty that I realized what had started me down my career path. One morning more than thirty-seven years ago, I was awakened by the passing school bus. I was thirteen years old, living at home with my two younger brothers and our mother, Doris Joy Heavin. She had just passed her fortieth birthday. She was a mother of five children and had suffered emotional and physical problems most of her life. Her doctor had tried various treatments on her with little benefit. As I awoke to the sound of the passing school bus, my brother Paul came in and told me that I'd better come quickly because mother was sick. As I knelt beside her bed, I could feel the absence of warmth. I put my arms around her, first to feel for a sign of life, and then as a final hug. I took my younger brothers, aged eight and nine, in my arms and gently told them that our mother was in heaven. Her death was unnecessary. The high blood pressure causing the blood clot that took her life was unnecessary. Rather than _ , she could have dealt with the cause of her high blood pressure: we now know that exercise and proper nutrition will almost always reduce the causes of high blood pressure and most other chronic diseases. Many years later, while teaching a fitness and weight loss class to a group of about eighty women, I realized I was subconsciously searching the crowd for the face of my mother. Question: From the passage we learn that _ . Answer:
OPTIONS:
- the author was the oldest child in his family
- the author's father died long before his mother
- high blood pressure is a kind of chronic disease
- many women were found with blood clot at the time
Answer:
high blood pressure is a kind of chronic disease
