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: 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.

Example Input: Article: Drew Gilpin Faust made history in 2007 when she became the first female president of Harvard University, Massachusetts, US. Faust is an excellent historian known especially for her work on the history of the American South. She was a professor of history at the University of Pennsylvania for 25 years. In 2001, she became dean of the Radcliffe Institute for Advanced Study at Harvard. Born in 1947, Faust grew up in a traditional family. She has often spoken of her "continued confrontations " with her mother "about the requirements of what she usually called femininity ". Her mother used to tell her, "It's a man's world, sweetie. And the sooner you learn that, the better off you'll be." However, the daughter was a rebellious one. For example, Faust would fight with her mother over whether it was suitable for her to drive a car at night, even if one of her three brothers was a passenger. "She was raised to be a rich man's wife," said a friend, Elizabeth Warren. "Instead she becomes the president of the most powerful university in the world." As a girl, Faust rebelled against not only the strict rules of femininity, but also the racial injustice that existed in her native Virginia. At age 9, after a conversation with her family's black handyman and driver, she sent a letter to President Dwight D. Eisenhower decrying racial injustice. When studying in Bryn Mawr, a women's college in Pennsylvania, she was a student activist who would go on to march in the civil rights protests in the 1960s. What would her mother, who never went to college and died in 1966, have to say about her appointment? "I've often thought about that," she said. "I've had dialogues with my dead mother over the 40 years since she died."
