Please answer this: Write a multi-choice question for the following article: Article: On May 2, 2012, Ashok Gadgil became the winner of the $100,000 Lemelson-MIT Award for Global Innovation . Each year, the honor is given to an inventor who has made a big difference in the lives of people in developing countries. Gadgil is a professor and physicist at the University of California, Berkeley. He spent thirty years helping people in need. His inventions have helped more than 100 million people around the world. "I chose to focus on problems where my knowledge of science could help," Gadgil said. In the 1990s, Gadgil designed his first life-saving invention after more than 10,000 people died from Bengal cholera because of the clean water crisis in India. His invention uses ultraviolet light to kill deadly disease-carrying germs from drinking water. It costs just one cent to clean five liters of water (about 21 cups). So far, the invention has provided safe drinking water for more than five million people in India and other developing countries. Gadgil's another important invention is the Berkeley-Darfur Stove . The long and violent war in Darfur, Sudan, has caused many people to move to foreign countries and live in refugee camps . They are given food aid. But people still have to travel a long distance five times a week to gather firewood to cook meals. This can be dangerous because of street violence in the area. To avoid danger, some spend much of their money used to feed their families buying firewood. The stove Gadgil created cuts fuel usage by 55%. That means people wouldn't have to leave the camps to find firewood as often. The invention also helps to save homes more than $300 a year. About 125,000 people and their families have been helped. As a professor, Gadgil encourages his students, "Be optimistic when you try a hard problem," he says. "It's when you solve a large problem that you can have a big influence on the world."

Problem: Given the question: Write a multi-choice question for the following article: Article: Now, everybody is taking _ . From your best friend to your favourite pop star, selfies are taking over Facebook and Sina Weibo. The word "selfie" was even named Word of the Year by Oxford Dictionaries in 2013. But why do people feel the need to take them? And are they doing us more harm than good? According to some scientists, humans have an area in their brain that controls social activity. Receiving 'LIKE' on a selfie you have posted online can be the same as someone stopping you in the street and speak highly of you on your appearance. The act of taking a selfie also puts you in a position of power. You are the director and the subject of your own work of art. It helps people feel in control of their appearance and can be a powerful tool. But can it go too far? Scientists warn that too much time spent on selfies can influence people's confidence, especially in teenagers. If you are spending a lot of time choosing the perfect selfie clothes, then there could be a problem. At the same time, posting selfies online can harm your personal relationships. UK studies found that many people find it hard to talk to people who are often posting selfies online. So next time you want to use your smartphone to take a quick selfie, it may be better to drop it straight back into your pocket.

input question: Write a multi-choice question for the following article: Article: Teachers say the digital age has had a good and a not-so-good influence on the American teenagers. More than 2,000 high school teachers took an online survey. 75 percent of the teachers said the Internet and digital search tools have had a "mostly good" use for their students' research habits and skills, But 87 percent agreed that these technologies "make the students not have enough attention." And 64 percent said the technologies "do little to help them in courses." Judy Buchanan is a director of the National Writing Project. Ms. Buchanan says digital research tools are helping students learn more, and learn faster. Teachers really like these tools, because they are ways to make some of learning exciting. Young people enjoy using these tools. And the goal is to help them become creative students of meaningful work, and not just that kind of copyist. But one problem the survey found is that many students don't have a good understanding of how to use the digital knowledge well. In other words, they trust too much of the information. Judy Buchanan says these students have not developed the skills they need to tell whether the online information is good or bad. Another problem the survey found is something that might not seem like a problem, at all, being-able to quickly find information online. Teachers say the ability of their students to work hard to find answers is becoming weaker. They say students depend too much on search engines and do not make enough use, of printed books or research, librarians. Besides, many teachers are also worried about the problem that the Internet makes it easy for students to copy work done by others, instead of using their own abilities.???
