Read the following article and select the best answer. Article: A team of researchers from Oxford University has demonstrated a self-driving car that is different from such cars being tested by Audi, Ford, etc. It' s much cheaper because it's based on off-the-shelf technology and controlled by an ordinary iPad. Instead of using GPS to understand the location, the car learns routes when a person is driving, and then asks after it's got it down, if the driver would like the computer to take over. As time passes, it's becoming very clear that people believe computers would be better drivers than humans. This has been proven by extensive research that indicates that computers are able to react more quickly to driving conditions, make smarter decisions, don't take risks, and don't make mistakes in concentration. They don't drink either, of course, which means accidents due to drunk driving could be reduced dramatically if the computer could take over when someone needs to get home from the bar. And the team says drivers don't need their cars to know everything about every road, condition or possible danger. Instead, they just need to know how to get from one point to another, and to do a good job of it when asked. To that end, the researchers have added cameras, lasers, a central computer to process information and a regular iPad. In practice, the car would learn how to get to and from places that the driver frequents, such as their work place, the local pub or grocery store. Once it has it down, the computer asks the driver if they' d like a rest. If so, they simply tap the iPad, and the car takes over. It' s very simple and doesn't require nearly the same number of devices as those being tested by other car companies. The researchers say people might be able to get the total price of the system below a hundred dollars. And of course, the iPad can be lifted out and carried away for other purposes when not being used as a driver assistant.

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. As a paper boy during high school, Buffett delivered two competitor papers, so that even when customers canceled one of the subscriptions , he could still make a profit from the other. 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. He keeps learning from books, street smarts and investigation, from both success and failure. In this way, he over achieved his aptitude ," said Charlie Munger, his... Question: Which is the main factor that determines Buffett's success? - His desire to learn. - His family background. - His education. - His cooperation with his partner.
