Article: When I was growing up, 16 was always a magical age, a symbol of maturity, responsibility and of course more independence and freedom. I sat through the hours of Driver's Ed classes eager to get out on the road. I couldn't wait to get my driver's license. But it's a different story for today's teens. In January, the U.S. Department Transportation released 2012 data that showed only 30.7 percent of U.S. teens got their license at age 16, Twenty years before, that number was almost 45 percent. There are numbers of reasons for the fall - off. The growing responsibilities like paying for insurance and high gas prices discourage teens from getting behind the wheel. Plus, many teens today are so busy with homework, endless hours of activities and part-time jobs, that finding the time for Driver's Ed classes may be more difficult that ever. In addition, many states have raised the driving age, or restricted when teens can drive and who they can have in the car. Parents may also be making their own personal restrictions until they feel their teens are responsible enough to drive safely. Driving is part of the American culture, but it's not the central focus like it was 25 years ago. They have so many other things to do now. One of the more interesting factors delaying teens driving might be the change of their social life. Today, teens need to look no further than Face book or other social networking sites to connect with their friends. There is simply less need, maybe less desire, to be able to grab the keys and go. Michelle Wei got her license as a senior in high school because her digital social life made it easy no to drive. "If I couldn't get a ride to see my friend who lives a town over," the 19-year-old said, "I could talk on IM or Skype." Research has shown that these online relationships can lead to higher quality friendships, so it isn't necessarily a bad thing. However, it's important to find a balance. If old face-to-face friendships are good, why not drive to find them?
Question: What does the passage mainly talk about?
Options: (A) Desire to drive on the road declines among American teens. (B) Getting a license costs much more than ever before. (C) Social networking sites are changing the life of American teens. (D) American teens are becoming more responsible than ever.

Article: Chinese New Year Celebration is the most important celebration of the year. Chinese people may celebrate the Chinese New Year in slightly different ways but their wishes are almost the same; they want their family members and friends to be healthy and lucky during next year. Chinese New Year Celebration usually lasts for 15 days. Celebratory activities include Chinese New Feast, firecrackers, giving lucky money to children, the New Year bell ringing and Chinese New Year Greetings. Most of Chinese people will stop the celebrating in their home on the 7th day of New Year because the national holiday usually ends around that day, however celebrations in public areas can last until the 15th day of New Year. It is the money given to kids from their parents and grandparents as New Year gift. The money is believed to bring good luck, ward off monsters; hence the name "lucky money". Parents and grandparents first put money in small, especially-made red envelopes and give the red envelopes to their kids after the New Year's Feast or when they come to visit them on the New Year. They choose to put the money in red envelopes because Chinese people think red is a lucky color. They want to give their children both lucky money and lucky color.

Article: Photography has been my interest ever since I was old enough to pick up a camera, but today I want to share with you the 15 most treasured photos of mine, and I didn't take any of them. There were no art directors, no stylists, no chance for reshoots, not even any regard for lighting. In fact, most of them were taken by random tourists. My story begins when I was in New York City for a speech, and my wife took a picture of me holding my daughter on her first birthday. We're on the corner of the 57thand 5thavenue. We happened to be back in New York exactly a year later, so we decided to take the same picture. Well you can see where this is going. Approaching my daughter's third birthday, my wife said, "Hey, why don't you take Sabina back to New York and make it a father-daughter trip, and continue the ceremony?" This is when we started asking passing tourists to take the picture. So these photos are far more than representatives for a single moment, or even a specific trip. They're also ways for us to freeze time for one week in October and reflect on our times and how we change from year to year, and nor just physically, but in every way. Because while we take the same photo, our viewpoints change, and she reaches new milestones and I get to see life through her eyes, and how she communicates with and sees everything. This very focused time we get to spend together is something we value and expect the entire year.
Question: Who came up with the idea of having a father-daughter trip when Sabina was 3 years old?
Options: (A) Her mother. (B) Her father. (C) Sabina herself (D) An unknown tourist.
