Article: Social media is one of the fastest-growing industries in today's world. A study conducted by the US think tank Pew Research Center showed that 92 percent of teenagers go online daily. The wide spread of social media has changed nearly all parts of teenagers' lives. Changing relationships High school student Elly Cooper from Illinois said social media often reduces face-to-face communication. "It makes in-person relationships harder because people give attention to their phones instead of their boyfriends or girlfriends," Cooper said. There's also a greater possibility of things getting lost in translation over social media. "If half of your relationship is over social media, you don't really know how the other person is reacting," Sienna Schulte, a junior student from Illinois, said. Yet, some people believe social media has made it easier to start relationships with anyone from anywhere. Beth Kaplan from Illinois met her long-distance friend through social media. He currently lives in Scotland, but they're still able to frequently communicate with one another. "I can feel close to someone that I'm talking to via FaceTime," Kaplan said. Wanting to be "liked" The rise of social media has changed the way teenagers see themselves. The 19-year-old Essena O'Neill announced on the social networking service Instagram that she was quitting social media because it made her obsessed with appearing perfect online. Negative comments also can do great damage to a teenager's self-esteem . In particular, anonymous social media apps such as Yik Yak may provide opportunities for cyber bullying . The app allows users within 5 miles (8 km) to create and add comments to everything. Teenagers who get negative comments on these sites can't help but feel hurt. Opening new doors However, Armin Korsos, a student from Illinois, takes advantage of the comments he receives over social media to improve his videos on the social networking site Youtube. "Social media can help people show themselves and their talents to the world in a way that was never possible before," Korsos said. But Korsos recognizes that social media has become a distraction . "Social media, though it helps people connect with their friends and stay updated, is not all necessary."

question:
Article: A mouse looked through a crack in the wall to see the farmer and his wife opening a package: What food might it contain? He was astonished to discover that it was a mouse trap! Retreating to the farmyard, the mouse declared the warning, "There is a mouse trap in the house, there is a mouse trap in the house." The chicken clucked and scratched, raised her head and said, "Mr Mouse, I can tell you this is a grave concern to you, but it is of no consequence to me, I cannot be bothered by it." The mouse turned to the pig and told him, "There is a mouse trap in the house." "I am so sorry, Mr Mouse," sympathized the pig, "but there is nothing I can do about it but pray; be assured that you are in my prayers." The mouse turned to the cow, who replied, "A mouse trap, am I in grave danger, huh?" So the mouse returned to the house, head down and depressed to face the farmer's mouse trap alone. That very night a sound was heard throughout the house, like the sound of a mouse trap catching its prey. The farmer's wife rushed to see what was caught. In the darkness, she did not see that it was an evil snake whose tail the trap had caught. The snake bit the farmer's wife. The farmer rushed her to the hospital. She returned home with a fever. Now everyone knew to treat a fever with fresh chicken soup, so the farmer took his hatchet to the farmyard for the soup's main _ . His wife's sickness continued so that friends and neighbors came to sit with her around the clock. To feed them, the farmer butchered the pig. The farmer's wife did not get well, in fact, she died, and so many people came for her funeral. The farmer had the cow slaughtered to provide meat for all of them to eat. So the next time you hear that someone is facing a problem and think that it does not concern you, remember that when the least of us is threatened, we are all at risk.
