Write a multi-choice question for the following article: Article: "Humans should not try to avoid stress any more just as they would not _ food, love or exercise," said Dr. Hans Selye, the first physician to record the effects of stress on the body. While here's one question that continuous stress is harmful, several studies suggest that challenging unexpected and difficult situations can be good for you. In a 2001 study of 158 hospital nurses, those who faced considerable work demands but dealt with the challenge were more likely to say they were in good health. In a study at theprefix = st1 /AcademicCenter, researchers put volunteers through a stressful experience: a timed task that required memorizing a list followed by a short test. Those who did well on the memory test had an increase in levels of immunoglobulin A, which is the body's first line of defense against germs . Stress makes the body produce certain stress hormones. In short bursts these hormones have a positive effect including improved memory function. "They can help nerve cells deal with information and put it into storage," says Dr. Bruce McEwen of Rockefeller University inNew York. But in the long run these hormones can have a harmful effect on the body and brain. "Continued stress is not good for you," says Dr. Bruce," it's the short burst of stress that could be protective."

Write a multi-choice question for the following article: Article: By now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friends' new baby on Facebook, or reading about Justin Bieber's latest conflict with the law on Twitter, what are some of the real influences? Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choice. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills. Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker. Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees. Also, what you carelessly post on the Net can come back to trouble you. Revealing( ) personal information on social sites can make users vulnerable to crimes like identity theft, stalking, etc. Many companies perform a background check on the Web before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too,...

Write a multi-choice question for the following article: Article: On a Saturday morning earlier this September, the world got its first look at the Strati. This electric vehicle is unlike any other currently on the road. It rolls on four wheels, but its body and chassis weren't built in a factory. Instead, Strati's designers used a technology called 3-D printing. It created those parts of the car in one piece, from the ground up. "Compared to a typical vehicle on the road, the Strati definitely looks different," says Greg Schroeder, a senior research engineer at the Center for Automotive Research in Ann Arbor, Mich. He did not work on the new car. His organization studies trends and changes in the auto industry. It took 44 hours to print the new car at the International Manufacturing Technology Show in Chicago. Over the next few days, the car's designers installed additional parts. These included the car's engine, brakes and tires. Then, early on September 13, Jay Rogers climbed into the car, started its engine and drove the vehicle onto the street. Rogers helped found Local Motors. It's the Arizona-based company behind the Strati. Two weeks later, his team printed a second Strati, and just as fast, at a fair in New York City. Justin Fishkin, a local Motors official, sees the Strati as a window into the future. Today, car buyers are limited in their choice of a vehicle. They can order only what car companies have already designed. But in the future, he says, you may be able to design your own car online and then get it printed to order. Manufacturing experts say 3-D printing has begun to revolutionize how they make things. The technology has been around for decades. But these machines used to be so expensive that only large companies could afford them. In the last few years, though, that has changed. Many of the machines are now inexpensive enough for small companies--or even individuals --to own. Some local libraries make them available to the public. High Schools are beginning to use them in classrooms. Wide access to these printers means people can now design and print...
