[Q]: Article: The sharing economy has grown in recent years to include everything from apartment sharing to car sharing to community tool sharing. Since 2009, a new form of sharing economy has been emerging in neighborhoods throughout the US and around the world---- Little Free Library. The libraries are boxes placed in neighborhoods from which residents can withdraw and deposit books. Little Free Libraries come in all shapes and sizes. Some libraries also have themes, focusing on books for children, adults, or tour guides. In 2009, Tod Bol built the first Little Free Library as a gift to his mother, who was a devoted reader. When he saw the people of his community gathering around it, exchanging conversation as well as books, he knew he wanted to take his simple idea further. "I think Little Free Libraries open the door to conversations we want to have with each other," Bol said. Since then, his idea has become a movement, spreading from state to state and country to country. According to Little FreeLibrary.org, there are now 18,000 of the little structures around the world, located in each of the 50 US states and 70 countries in Europe, Africa and Asia. The Internet has helped to spread Little Free Libraries. But an Atlantic article says the little structures serve as a cure for a world of e-reader downloads. The little wooden boxes are refreshingly physical and human. For many people, the sense of discovery is Little Free Libraries' main appeal. "A girl walking home from school might pick up a graphic novel that gets her excited about reading; a man on his way to the bus stop might find a volume of poetry that changes his outlook on life," says the Atlantic article. "Every book is a potential source of inspiration".
Question: How do Little Free Libraries get their books?
Options: (A) The communities bought them. (B) Tod Bol donated them. (C) US government provided them. (D) Citizens shared them.
[A]: D

[Q]: Article: When you are far away from home for the first time and have a lot to adjust to,you can't do it alone. However independent you are,it is good to have a roommate during your first year. Living with someone helps ease your loneliness. Sure it may seem appealing to be able to play your music and turn up your TV as loud as you want, but coming home to an empty room every day can be depressing. If you have a bad day, you may want to talk to someone. Friends are great sources of venting , but friends can't always be there. Even worse, they may be selfcentered and show no interest in your problem. It's not that roommates aren't like this, but even just small talk can help you feel better. Having a roommate teaches you how to get along with people and settle conflict. You two should set up rules immediately and discuss what to do when there is conflict. If you two don't like each other,you still study,relax,and sleep in the same room. You must find a way to get along. Finally,having a roommate exposes you to different ways of living. Your roommate may come from a different city,and have different living habits. He or she also has different interests and personalities. You don't have to end up liking the same things your roommate does,but try to learn something different. You will be surrounded by many different people in college and have the chance to try things you never have before. Why not start learning from your roommate? Having a roommate gives you the skills and personal background you will need to utilize when you are out on your own. Make the most of living with a stranger and besides,there will be plenty of opportunities for you to have your own room later in your college years.

[Q]: Article: Why do plants grow in some places and not in others? Why does some land have so much growing on it, while other land has almost no plants growing on it at all? To grow, plants need several things. One is warmth. In very cold places almost nothing grows. Plants also need water. In very dry parts of the Earth only a few unusual plants can grow. That's why dry deserts everywhere are almost not covered by trees or grass. Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The plants here have only the soil found between the _ cracks of the stones to grow in. Another thing plants must have before they can grow is food. What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won't.
