Example Input: Article: Selfie is a photograph taken of oneself, typically with a smartphone or webcam and uploaded to a social media website. In the digital age, selfies have taken off in a way that no one could have predicted. The art of the selfie is one that lots of people have practiced and perfected in recent years. A recent study shows 91 percent of teens have posted a photo of themselves online. Some celebrities are regular selfie posters, too. It seems that selfies are more than just a trend. They are here to stay. Why are selfies so popular? The appeal of selfies comes from how easy they are to create and share. And posting selfies is popular for another reason: you can control your own image. "I like having the power to choose how I look," admits Samantha, a 19-year-old girl from Missouri, "even if I'm making a face." Actually, the most common selfie is the one where you look cute, partly because it's a quick way to get positive comments about your appearance. "If I feel pretty, I take one," says Andrew, a 23-year-old girl from Maryland, "when other people Like it, it's a mini boost of confidence." Sure, showing off a new coat or that you're at a cool event is fun, but can be a trap to fall in. There's a danger that your self-respect may start to be tied to the comments and Likes you get when you post a selfie, and they aren't based on who you are--they are based on what you look like. Seeking validation is totally normal, and it's a healthy way for teenagers to develop their identity. But with social networks, where it's easy to get quick approval almost constantly, the selfie thing can quickly go out of control. It may even start to feel like an addiction: when you get a "LIKE", you're up. But when you get nothing, your confidence can decrease quickly. Overall, opinions vary on selfie culture. It's up to you to shape the future of the habit. Ask yourself: are my selfies for fun, or do I need the comments? If you belong to the latter, it's recommended that you change your view. That could mean cutting selfies out entirely or just cutting down and making them more fun. So maybe you like to travel, or read or dance, or create crazy 3-D nail art...post them! Take it from us: it's so much more interesting.

Example Input: Article: Sam, an unemployed piano tuner, said it was only the second thing he had ever won in his life. The first thing was an Afghan blanket at a church raffle when he was 25 years old. But this was much bigger: it was $120,000! He had won the Big Cube, a state lottery game. To win, a contestant must first guess which number a spinning cube will stop on. The cube has six numbers on it: 1X, 10X, 50X, 100X, 500X, and 1000X. If he is correct, the contestant must then guess which of two selected variables is going to be greater. So, just guessing which number appears on the cube does not guarantee that you will win any money. Sam correctly guessed 1000X, but he still had to choose between two variables. One variable was the number of cars that would run the stop sign at Hill Street and Lake Avenue in six hours. The other variable was the number of times that a teenage boy would change TV channels in a three-hour period. This was a tough decision. Finally, Sam flipped a coin. It came up heads, so Sam picked the teenager. He picked right. The stop sign was run only 76 times, but the teen clicked 120 times. Sixty-year-old Sam jumped for joy, for he had just won 1000 times 120, or $120,000. Sam dreamily left the lottery studio. Talking excitedly on his cell phone while crossing the street, he got hit by a little sports car. Sam is slowly getting better. He was in the hospital for a month. His hospital bill was $110,000. And the insurance company for the little sports car's owner sued Sam for $9,000 worth of repairs. Also, Sam still has to pay federal taxes on his winnings. Sam doesn't play the state lottery any more. He says it's better to be unlucky.
