Input: Consider 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.

Input: Consider Input: Article: Each Indian was supposed to keep his birth name until he was old enough to earn one for himself.But his playmates would always give him a name of their own.No matter what his parents called him, his childhood friends would use the name they had chosen.Often it was not pleasing, such as Bow Legs or Bad Boy.But sometimes a name fit so well that the youngster found it difficult to shake it off.If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life. The Indian earned his real name when he was old enough for his first fight against the enemy.His life name depended on how he acted during this first battle.When he returned from the war, the whole tribe would gather and observe the ceremony in which he would be given his name by the chief.If he had done well, he would get a good name.Otherwise he might be called Crazy Wolf or Man-Afraid-Of-a-Horse.So an Indian's name told his record or described the kind of man he was. A man was given many chances to improve his name, however.If in a later battle he was brave in fighting against the enemy, he was given a better name.Some of our great fighters had as many as twelve names--all good and each better than the last. An Indian's names belonged to him for the rest of his life.No one else could use them.Even he himself could not give them away because names were assigned by the tribe, not the family.So no man could pass on his name unless the chief and the tribe asked him to do so. Sometimes an Indian would be asked to give his name to a son who had performed a noticeable deed.I know of only three of four times when this happened.It is the rarest honor for a person--the honor of assuming his father's name.

Options: (A) his father (B) the enemy (C) the chief of the tribe (D) his childhood friends
