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.

Example Input: Article: When young people begin to live independently, home-hunting can bring some stress. But they would do well to remember that a new alternative is available--micro-home. Called "tiny houses", these houses have all living necessities in a small package, including kitchen, bedroom and bathroom. Generally under 50 square meters, most tiny houses accommodate just one or two people though some claim the space for more. What's lost in size is not lost in design as these homes are often quite unique and modern in design. Besides an attractive appearance, tiny houses can also have unique practical features. Making the best of urban space, the 72- to122-centimeter-wide Keret House in Warsaw, the world's narrowest home, fills in an alley. The Ecocapsule home uses solar power, wind power and rainwater collection to enable its owner to live practically anywhere. A system of rails allows the DALE micro-home to adjust room size and number as well as adding the option of an open or enclosed courtyard. Visually appealing as micro-homes are, there are a few drawbacks to consider before getting cozy on a mini-couch. Moving into a tiny house requires the removing of most non-essentials, regardless of the emotional connection to them. Guests will also mostly be out of the question as the limited space may even cause a solitary individual to experience some cabin fever . And finally, a micro-home is likely a temporary living option for most people since they will probably start families and acquiremore possessions. Though the limitations will scare some, there is usually a benefit. A small size results in a small price tag and small bills, making tiny houses easier to save up for and budget. And though you won't have much stuff around the house, this can provide the comfort of simple living and repairs. Micro-homes are also practically mobile and have eco-friendliness that can't be matched by other homes. They probably aren't for everyone or forever, but when it comes to your next (or first) home, they could be just what you need.
Question: Micro-homes are especially fit for _ .
Options: (A) a young couple in hope of settling down permanently (B) an individual constantly suffering from cabin fever (C) a college graduate on a tight budget for the time being (D) a family of five in favor of environmental protection
Example Output: C

Example Input: Article: ,. Three-year-old Teddy Lasry was sleeping in his cowboy outfit yesterday at his family's Fifth Ave.apartment when he shot up in bed screaming.A 3-foot-long black-and-white snake twisted around his left arm and had just bitten his little finger. "The babysitter (a person taking care of children while their parents are away for a short time) was frightened to death," said Teddy's father, David Lasry, who, along with his wife, Evelyn, was at work when the snake appeared about 4:00 pm. The horrified babysitter called 911 and the building's doorman.The doorman and two cable TV workers helped take the snake off the boy's arm and put it in a garbage bag.Police rushed Teddy to Mount Sinai Medical Center, where he spent two hours attached to a heart monitor as a precaution in case the snake was poisonous.It wasn't.Experts at the snakebite treatment center at Jacobi Medical Center in the Bronx, where policemen took the snake, found out it was a non-poisonous California king snake. But how did it end up in Teddy's bed? A little detective work determined that the snake had escaped two weeks ago from its cage in the apartment of a doctor whose family lives four floors below the Lasrys.The apologetic owner said his son's pet snake likely traveled up the water pipes and into his neighbor's apartment."It's a very gentle, very harmless snake," he said."It's handled by our family all the time." David Lasry believed the pet was simply hungry after two weeks of wandering.Evelyn said her son seems to have overcome his fright by thinking of himself as a hero cowboy as he rode in the back of the police car to the hospital. "I told Teddy he's a pretty snake, a nice pet snake who got out of his cage," Evelyn said."But he asked, 'Why did he bite my finger, Mamma?' And I said, 'Because he saw that you are a big boy, Teddy, in your cowboy outfit and he got scared.'"
Question: What did the babysitter do after Teddy was bitten by a snake?
Options: (A) She ran out of the apartment. (B) She called the TV company. (C) She made an emergency call. (D) She took the snake off Teddy's arm.
Example Output: C

Example Input: Article: Move Earth--it's no science fiction LONDON--Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system. This idea for improving our climate comes from a group of US National Aeronautics and Space Administration(NASA) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet--effectively doubling its working life. The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams is designed to carefully direct a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth. "Earth's orbital speed would increase as a result and we would move to a higher orbit away from the Sun," Laughlin said. Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated. In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so "seriously _ " our biosphere by cooking us. That's why the group decided to try to save Earth. The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation in orbit could fire it straight at Earth--with deadly consequences. There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is "most likely the Moon would be stripped away from Earth," it states. This would greatly change our planet's climate.
Question: What makes the scientists plan to move Earth?
Options: (A) A few comets are moving to the direction of Earth. (B) Earth's working life is coming to an end soon. (C) Earth will become too hot for mankind to keep alive. (D) The moon is moving farther and farther away from Earth.
