PROBLEM: 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.

PROBLEM: Article: It is amazing to note that the Internet is still such a new device, and yet it is one of the fastest and most powerful media tools. But think about it for a moment. On the Internet, a big online company can be run by two guys out of their garage. So it is only reasonable that people shopping on the Net would be a little _ of the security levels. Internet giants such as Microsoft knew consumer confidence was the key to getting virtual shopping off the ground, and they work hard to make people feel safe to shop online. Credit card companies, too, quickly saw the potential for Internet shopping, and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases, many credit card companies will happily refund your money and then set their claws on the company that wronged you. Now that's buying power! There are other bonuses for online shoppers, of course. No line-ups, for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won't get them what they want. When shopping online, consumers can sit down, have a coffee, and wear their slippers, not have to worry about their hair or parking and just click through sale after sale. Comparison shopping couldn't be any easier. And thanks to courier companies getting in on the act, you never need wait longer than a day or two to get those all important purchases delivered right to your door. No wonder so many companies are shaking their heads at traditional advertising and instead looking to the "virtual" world to attract online shoppers.
Question: _ leads to consumers' trust in online shopping.
Options: (A) Shopping law (B) Shopping convenience (C) Internet access (D) Shopping security

SOLUTION: D

PROBLEM: Article: Making greener choices and encouraging healthy lifestyles can promote your health and benefit the environment. Here are some guidelines to follow: Choose foods thoughtfully Americans have never had such a variety or abundance of food to choose from. Besides so many choices, we now hear about our "food print", the amount of land needed to supply one person's nutritional needs for a year. Do we buy cherry tomatoes from Mexico or tomatoes grown locally in a hothouse? Do we get the Granny Smiths from the farmers' market or the supermarket? Is organic produce healthier for us and the planet? These are very complex issues that require analysis of many criteria, including the energy used in producing and transporting the food, as well as the type of soil and methods of raising the food. Despite the complexities, there are some general guidelines you can follow. For instance, eat less meat or eat low on the food chain. Your doctor may have recommended you to restrict your consumption of red meat because of its too much fat content. Beyond that, there are environmental reasons, too. Raising food animals contributes substantially to climate change because a meat-based diet requires more land, energy and water than a plant-based one. _ Drinking plenty of fluids is significant during hot weather or when exercising. But is bottled water the way to go? You may not think so when seeing the true costs. Based on a survey, manufacturing the 30-plus billion plastic water bottles can produce more than 2.5 million tons of carbon dioxide and use three times the amount of water in the bottle. Adding in transportation, the energy used comes to over 50 million barrels of oil equivalent . Consequently, skip the bottled water and drink tap water, both at home and at restaurants. Additionally, bottled water is not necessarily cleaner than tap.
Question: In Paragraph 2 the author puts forward three questions mainly _ .
