Using a web camera equipped in Jennifer's Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down? In the battle against cheating, this is the _ and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven't just searched the Internet to get the right answers.

Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance. Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students' identities using personal information, such as the telephone number they once used. Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating. Question: Why was Jennifer watched in an online exam? Options: A: To correct her typing mistakes. B: To find her secrets in the room. C: To prevent her from slowing down. D: To keep her from dishonest behaviors.

So, I began looking around for individuals who would be my first investors. "Angel money" it was called. But when I reviewed my list of acquaintances to find those who might be able to help, I found the number got small. With no other choices, I began meeting with the venture-capital companies. But I was warned they took a huge share of your company for the money they put in. And if you struggled, they could drop you cold. As I was searching for "angel money", I started to build a team who trusted me even though I didn't have money for paychecks yet. Bill Becker was an expert in computer programming and image processing at a very famous Media Lab at M. I.T. With his arrival, my company suddenly had a major technology "guy" in-house. Katherine Henderson, a filmmaker and a former real-estate dealer, joined us as our director of market research. Steve White came on as operating officer. He had worked for the developer of a home-finance software, Quicken. We grabbed him. We had some really good people, but we still didn't have enough money. One night, my neighbor, Louise Johnson, came for a visit. She and I were only nodding acquaintances, but her boys and ours were constant companions. She ran a very good business at the time. Louise was brilliant and missed nothing. She had been watching my progress closely. She knew I was dying for money and I had prospects but could offer no guarantees of success. She told me that her attorney had talked to mine and the terms had been agreed upon. She handed me an envelope. Inside was a check for $ 500,000. I almost fell down. I heard her voice as if from heaven. "I have confidence in your plan," she said. "You' 11 do well. You're going to work hard for it, but it' s satisfying when you build your own company." Who would have thought I'd find an angel so close to home? There were no words sufficient for the moment. We just said good night. She...

Q: Read the article and select the best answer. Article: If your cellphone suddenly stops working, don't blame the service provider.The malfunction might well have been caused by something bigger -- a solar storm.Experts expect that Earth will see more solar activity in the near future.The malfunction of electronic devices will just one of the effects. Sunspots serve as an indicator of the sun's activity.For the past two years, sunspots have mostly been missing.Their absence, the most prolonged in nearly 100 years, has taken even seasoned sun watchers by surprise. When the number of sunspots drops at the end of each 11-year cycle, solar storms die down and all become much calmer. This "solar minimum" doesn't last long. Within a year, sunspots and solar storms begin to build toward a new crescendo, the next solar maximum. What's special about this latest cycle is that the sun is having trouble starting the next solar cycle. The sun began to calm down in late 2007, so no one expected many sunspots in 2008. They should return in 2010. Scientists have predicted that the next solar cycle could be the most active on record: more sunspots and more solar storms. However, sunspots are mostly missing now. Since the earth is in close contact with the sun, strong solar activities can bring trouble to our life. People of the 21st century rely on high-tech systems for the basics of daily life. Air travel and radio communications can be affected by strong solar activities. A big solar storm could cause 20 times more economic damage than Hurricane Katrina. What the sun will do next is beyond our ability to predict. Most astronomers think that the solar cycle will go on but at low level. However, there is also evidence that the sun is losing its ability to produce sunspots. By 2015, they could be gone altogether. Question: What is the passage mainly about? Options: A: The earth is in close contact with the sun. B: Sunspots can cause trouble to our life. C: Introduction of sunspots. D: Introduction of the solar storm.
