Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.
One example: Article: Homework can put you in a bad mood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Now, solve this: 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."
