I'm taking a test and have to guess the right answer to the question after the article. Article: Many of us enjoy doing it: you turn on the camera on your mobile phone and hold it at a high angle--- making your eyes look bigger and your cheekbones more defined. You turn to your best side and click. There it is - your selfie. Over the past year, "selfie" has become a well-known term across the globe. This August the Oxford dictionary added the word to their online dictionary and define it as: "A photograph that one has taken of oneself, typically with a smartphone or webcam and uploaded to a social media website." Today it's not difficult to find social networking pages full of photos people have taken of themselves and their friends. And selfie culture has become especially relevant for young people. As many as 91 percent of teenagers have posted photos of themselves online, according to a recent survey by the US Pew Research Center. So what are the reasons for the rise of selfie culture? "The craziness about the selfie celebrates regular people," Pamela Rutledge, a professor at the Massachusetts School of Professional Psychology, told Vogue magazine. "There are many more photographs available now of real people than models." Posting selfies also allows you to control your image online. "I like having the power to choose how I look, even if I'm making a funny face:' Samantha Barks, 19, a high school student in the US, told Vogue. In addition to self-expression and documentation , selfies "allow for a close friendship for long-distance friends, because you can see each other's faces every day", wrote Casey Miller at The Huffington Post. But US psychologist Jill Weber is concerned that selfies might lead to social problems. "There's a danger that your self-esteem may start to be tied to the comments and '1ikes' you get when you post a selfie, and they aren't based on who you are - they're based on what you look like," Weber told Vogue. "When you get nothing or a negative response, your confidence can decrease." Question: Many people post photos of themselves online to _ . Options: A: make fun of themselves B: become powerful C: beautify themselves D: choose how they look

I'm taking a test and have to guess the right answer to the question after the article. Article: If you thought taking vitamins would reduce the risk of lung cancer, think again. Researchers who studied 77,721 people said on Friday that people who took too much vitamin E,especially smokers,had a small but higher risk of developing lung cancer. They tracked the subjects'use of multi-vitamins,vitamin C and vitamin E to see if it offered protection from lung cancer.But they found that none of the vitamins was tied to a reduced risk. "If you could find some sort of magic pill--a pill you could take once a day to decrease your risk--that would be wonderful.But unfortunately.we didn't find that in our study,"lead researcher Christopher Slatore,of the University of Washington Seattle,said. The subjects of the study were followed for four years,and 521 developed lung cancer,the majority of them smokers or former smokers,Slatore's team reported in the American Journal of Respiratory and Critical Care Medicine. Among those in the study who developed lung cancer, the researchers saw a small increased risk related with vitamin E supplements in addition to the expected connections to smoking,family history and age. This added up to a 28 percent increased risk of developing lung cancer for those taking 400 mg of vitamin E supplements daily for 10 years,the researchers said. "For people--especially smokers--I suggest that they not take vitamin E(as a supplement) unless they have a very strong reason to take it." Slatore said. The idea that vitamin supplements are healthful,or at least not harmful.comes from the desire of many people to match the benefits of a healthful diet with a convenient pill,Tim Byers of the University of Colorado School of Medicine.wrote in an essay. Question: What is the main idea of the passage? Options: A: Taking vitamins would reduce the risk of lung cancer. B: Vitamins are no guard against lung cancer. C: Vitamin supplements are convenient and magic. D: Vitamins ale harmful,or at least not healthful.
