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: Study-abroad programs are a great way to learn about different cultures. Sometimes students don't have the money to join in these programs. That is why scholarships for study-abroad programs are starting to become popular.    Study-abroad programs can often be quite expensive. Finding scholarships is not that difficult. Usually, you can just visit the study-abroad office at your educational institution or even the financial services office. They will have a large directory  of available scholarships. If  your school does not have these offices, you can just quickly have a look on the Internet and find a wide variety of scholarships you might qualify for.    The credentials you need to be considered for a scholarship vary greatly. But, to be a candidate for any scholarship, you generally need to have good grades, be an outstanding person, and be able to take full advantage of the opportunities presented to you. You will be able to show why you are a good candidate through the application process.     The application process for each scholarship varies, which usually includes submitting  an academic record, an essay, and sometimes an interview. Usually, you will have to submit your academic records. The administrators of the scholarship will know that you take your academic studies seriously. Next you usually need to write an essay. This could be on a wide variety of subjects, but they usually focus on something related to 'why you should get this scholarship' to determine how much you want the scholarship and how good of a candidate you would be. After this, the final few applicants may be asked in for an interview to learn about you and why you would be a good recipient  of the scholarship. If you satisfy all these requirements, there is a good chance you will get a scholarship. If you don't have enough money, don't give up but use plenty of scholarship opportunities for you!
