Example Input: Article: When people who are nature lovers worldwide wish all humans to realize the importance of their natural surroundings, many Australians are turning caring for the environment into a way of life. Julie, an Australian housewife in Brisbane is one such example. Even though autumn is approaching Australia's Brisbane in April, one can still watch colorful blooming flowers in Julie's little garden, as she tells that in her community,"Each of us has a beautiful yard. The whole community, from children to elderly people, takes care of the environment as if they are taking care of their own garden." "Gardening is the most popular club in our community," she says. "A lot of retired people don't just regularly organize gardening lectures, but also personally visit families in the community to provide gardening training. So you can see that flowers continue to blossom in our gardens throughout the year." Talking about her people's sense of caring for the environment, Julie says when people in the community take along their dog, they always carry a garbage bag to deal with the dog's waste. "In our community, you will never experience the embarrassment of stepping on the dirty waste while you are walking on the grass," says Julie with a smile. "Taking care of the dog's waste can also help to develop children's sense of responsibility!" As to protecting water resources, the Australian government has made strict rules for families. Julie says, "We certainly would not use tap water to water the flowers!" She says almost every family in her community has a huge tank used to store rainwater, which is later used as the resource of all outdoor water use, including car washing and watering the garden. This year, they also asked people to connect the water tank with their toilets.
Question: Why can flowers be seen all year round in Julie's community?
Options: (A) Families are taught how to take care of their gardens. (B) Gardening lessons are often given by professors. (C) The local government provides free gardening training. (D) There is enough rainwater to water the flowers regularly.
Example Output: A

Example Input: Article: In reflecting on the events of my life that have impacted me, I returned to the night of August 1, 2006. I found myself in a hall in New York City sitting by my mother, not at all tired, although we had flown the day before, and driven five hours to the city for "An Evening with Harry, Carrie and Garp," a charity event with readings by three authors. The excitement rushing through me kept me awake and thinking; I was standing and applauding a woman as she prepared to read. The Harry Potter series was my gateway to my academic adolescence. I was so fascinated by the magic world that my mother began taking me to academic conferences focused on the books. Since 2005, I have attended presentations about the Latin origin of terms and spells, the ancient tales, and the idea of magic. These books opened my eyes to the whole world, and to knowledge itself. They kept my brain working over the summers. More importantly, they helped me adopt the ideas useful in school and beyond, that there is always another way to do something, or to understand an issue. With uncertainty and doubt come creative ideas and new ways to look at problems that may result in new, different, faster and easier solutions. And all this came from a little "magic" from a book that many people see as a series for children. I also attended lectures about Ms. Rowling's ability to beautifully write the story, with every small detail connected to something else, for example, details in books by Jonathan Swift to Chaucer to Dickens and Austin. I learned that like all great books, Rowling's stories encouraged a connection across mind, body, and soul. Although the series has been criticized by those who believe it encourages bad behavior in children, I was able to hear discussions by those who claimed that these books teach wonderful messages if one gets its deeper meaning. It is my generation's shared text; all college freshmen are familiar with the stories, and that gives us a set of common beliefs and ideas that help us start to learn new things.
Question: What did the author do on the night of August 1, 2006?
Options: (A) He flew for a charity event. (B) He drove tiredly back home. (C) He listened to readings by some authors. (D) He enjoyed the excitement of driving.
Example Output: C

Example Input: Article: You do something about twenty times a minute without even thinking about it--you breathe! In fact, every day you take about twenty-thousand breaths. The organs of your body that allow you to breathe are called your lungs. You have two of them that work together, located in your chest inside the rib cage. The main purpose of your lungs is to breathe in good air and breathe out bad air. The good air contains oxygen, which your body needs. The bad air is a gas called carbon dioxide, which your body cannot use. When you breathe in through your nose or mouth, air travels down the back of your throat. It passes through your voice box and into your trachea, or windpipe. Your trachea is divided into two air passage tubes. One leads to your left lung. The other leads to your right lung. Inside your lungs, oxygen is removed from the air you breathe and pumped into blood cells. Your lungs also get rid of harmful carbon dioxide from these cells. This process takes place inside hundreds of millions of tiny air sacs. Each adult lung is about the size of a football. When they are healthy, your lungs feel a little like a sponge and are pinkish-gray. When lungs are damaged by smoking, they can appear gray or have black spots on them.One disease that is very common in children involves the lungs. It's asthma. Asthma narrows the breathing tubes, making it harder to breathe. You probably already know that your lungs are important when you swim. But you may not know this--your lungs are the only part of your body that can float on water!
Question: Where are your lungs?
Options: (A) In the organs of your body. (B) inside the rib cage of your chest. (C) between your nose and mouth . (D) at the back of your throat.
