Q: Write a multi-choice question for the following article: Article: More and more people are taking their iPads to bed with them to surf the web, check facebook or send e-mails before switching off the light. But researchers are warning that the blue light their screens give off can stop users getting a good night's sleep. That is because this type of light is similar to daylight, convincing the brain that it is still daytime. Blue light prevents the production of a brain chemical called melatonin, which helps us fall asleep. By contrast, light which is more orange or red does not prevent melatonin production, perhaps because our brains recognize it as a cue that the day ends. Scientists have known for years that staring at screens late in the evening can affect sleep ---- they are television screens, computer screens or mobile phone screens. However, because mobiles and iPads are by nature portable ---- not to say addictive ---- more people are taking them into the bedroom. Users also tend to hold them much closer to their eyes than a computer or television screen. Researchers are warning that looking at iPad displays for more than two hours leads to lower natural melatonin levels as the devices give off blue light. They say, "Turning off the devices at night is the final solution. But if you have to use these devices at night, dim the display to cut down irritation of the eyes and limit the time you spend on them before bed." They wrote in the journal Applied Ergonomics that iPad makers should adjust the spectral power distribution of the devices so that they affect the sleep patterns of users less. It is not just a good night's sleep that could be harmed by too much late night screen time. Researchers know that long-term harm to sleep patterns can lead to an increased risk of obesity and even cancers.

Q: Write a multi-choice question for the following article: Article: There was once an old wise man living on the top of a mountain. Whenever the villagers had a problem, they would climb up the mountain and ask the old man for advice. One day a young man arrived. "Wise man," he asked, "What makes a man truly great?" The old man said, "Do you sincerely want to know?" "Yes, yes!" the young man replied. "Well," the wise old man said to him, "Let me tell you in the form of a story." There was once a Greek man who suffered from a deadly disease. Knowing that he would die soon, he was the first to join the army when his country was in a battle with the enemy. Hoping to die in battle, he would fight in the front line, risking himself without any worry for his life. Finally they won the battle and he was still alive. His general was so impressed with his bravery which contributed much to the victory. The general decided to promote him and award him with medals of bravery and honor. On the day of presentation , he was looking very down and sad. Curiously, the general asked him why he was so sad on a day he should be so proud. The soldier told him of his deadly disease. "How could I let such a brave soldier die?" the general thought. So the general hired the best physician and finally cured the soldier. But from that day on, the once _ soldier was no longer seen at the front. He would always avoid danger and tried his best to protect his life. "Young man," the wise man said, "if you want to be truly great, you must not be afraid of dying, you must be daring."

Q: Write a multi-choice question for the following article: Article: Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It's awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way. It may sound risky, so many teens stay within their own social circles to find rides, and don't branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern. "I think the digital connection of young people is really key, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they've been very used to sharing," said Juliet Schor, a sociology professor at Boston College. The sharing economy got big during the recession , allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, "The symbol of freedom isn't the car any more because there's technology out there connecting you to a car." According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver's license compared to six in ten today. So it's not that surprising that on my 16th birthday I wasn't rushing to get a license but an iPhone. "Driving, for young people, does mean they have to disconnect from their technology, and that's a negative. So if they could sit in the passage side and still be connected, that's going to be a plus." Schor continued. To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.
