Example Input: Article: After 10 seasons wearing the No.8 on his back, Kobe Bryant will become No.24 next season. The reason for the surprising decision by the Los Angeles Lakers super guard last week has become a hot topic for debate. Bryant wore No.24 when he was in early high school, but he changed to No.33 in his senior year. He switched to No.8 when he was selected by the Lakers in 1996, and has been not changed since. Bryant has refused to explain the decision until the end of the play-offs. So guessing Bryant's motive has become a popular game among NBA fans and newspaper columnists. There are all kinds of speculations . Many say that Bryant wants to leave the past behind and have a fresh start. He has often been criticized for playing to benefit himself and not the team as a whole.

Some, such as NBC Sport columnist Michael Ventre, argue that it is "all about money". Bryant will make more money by selling new jerseyto his fans. Some speculations are more about fun.

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.
