Example Input: 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.
Example Output: D

Example Input: Article: This is a true story that happened in Japan. In order to _ the house, a Japanese tore open the walls. Japanese houses normally have a empty space between the wooden walls. When tearing down the walls, he found that there was a lizard stuck there because a nail from outside was hammered into one of its feet. He saw this, feeling pity and curious. When he checked the nail, he found it was nailed 10 years ago when the house was first built. What happened? The lizard had survived in such a position for 10 years! It has been in a dark wall partition for 10 years without moving! Then he wondered how this lizard survived for 10 years without moving a single step--since its foot was nailed! So he stopped his work and observed the lizard: What has it been doing? What and how has it been eating? Later, he didn't know from where another lizard appeared, with food in its mouth. Ah! He was astonished and touched deeply. The free lizard had been feeding the stuck one for the past 10 years. Such love, a beautiful love! Such love happened with this tiny creature... What can love do? It can do wonders! Just think about it: one lizard had been feeding the other one untiringly for 10 long years, without giving up hope on its partner. If a small creature like a lizard can love like this, just imagine how we can love if we try.
Question: How did the Japanese feel when seeing the stuck lizard?
Options: (A) Frightened (B) Enjoyable (C) Confused (D) Usual
Example Output: C

Example Input: Article: How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that's more than an academic question, as Tracy Smith reports in our Cover Story. There are now more than a thousand genetic tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer' . "If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up." Said Dr. Robert Green, a Harvard geneticist. "Every ache and pain," Smith suggested, "could be understood as the beginning of the end." "That 's right. If you ever worried you were at risk for Alzheimer's disease, then every time you can't find your car in the parking lot, you think the disease has started." Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer's. It was thought that people who got bad news would, for lack of a better medical term, _ . But Green and his team found that there was "no significant difference" between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.
Question: Which of the following is true about James Watson?
Options: (A) He doesn't want to know his chance of getting a disease. (B) He is strongly in favor of the present genetic tests. (C) He believes genetic mapping can help cure any disease. (D) He is more likely to suffer from Alzheimer's disease.
