Example Input: Article: We are much happier in our new house because it has a large garden, and you know how enthusiastic we both are about gardening. When we moved in a month ago, Mary wanted to get a dog to keep out burglars. However, we finally decided that it would be cheaper to put an iron grille in front of the door and get a burglar alarm. Last week, I went to a shop and bought an alarm for just over PS200. It consists of a control unit with three smaller units. I put the control unit in the lounge and put the other units in place by the front door, back door and lounge windows. That night I soon fell asleep because I was confident that no one could get into our house undetected. At about 1:50 a.m. I woke up suddenly and heard the siren. It was like an ambulance driving right through our bedroom. I couldn't leave the siren on all night. I went downstairs in the dark. When I reached the bottom of the stairs, I switched on the light and looked around. Oh my gosh. The back door was unlocked. I rushed to lock it and it was just at that exact moment that the 'burglar' disappeared behind a curtain. Guess what? It was an ordinary house lizard .Apparently the alarm system had been made for American or European homes in which lizards are never seen. I switched the alarm off and sat down to watch. A few moments later, a lizard ran across a wall, right in front of one of the alarm units. I won't bother to finish this story but if you'd like a burglar alarm system free of charge, just let us know.

Example Input: Article: On a Friday night in May 2015, Oliver and Lone Kleven heard angry shouts coming from their front lawn. Lone, 68, stepped onto the porch and saw two men in dark clothes struggling with something on the ground--right where she and her grandson had planted a flower bed the weekend before. "Go fight somewhere else!" she shouted, worried her plants would get damaged. At the sound of her voice, the face of a boy appeared from beneath the two men. He looked 13 or 14 or so. "They're trying to kill me!" the boy screamed. Lone ran toward them and, without hesitation, caught the boy's arm, pulling him out. "Leave _ alone!" she shouted. When the men stood up, Lone saw what looked like a sharp object in one man's hand. When she turned back toward the boy, he was moaning in pain and holding his stomach. The attackers began to move in on the boy again when Lone's husband shouted: "Get lost!" The two men walked quickly and quietly across the street and drove off in a dark car. "I have to get to the hospital!" the boy cried. He lifted his shirt, and Lone could see a bloody wound on his stomach. Oliver hugged the trembling boy while Lone caught her cell phone and car keys inside the house. She handed the phone to Oliver. "Call 911," she told him. "I'm going after them." Lone took off but was unable to find the car. The Klevens then learned what had happened. Earlier that night, as the boy waited for his parents to pick him up from the high school across the street from the Klevens' house, two men approached and demanded his wallet. When he refused, one of the men hit him in the face. The boy ran across the street. The men caught up with him, and one hurt him in the back and stomach with a sharp knife. That's when Lone stepped in. The boy's wounds required operations, but he has fully recovered. "He was alone and outnumbered," says Lone. "There was no time to do anything except what I did."
Question: Why did Lone shout at the man at the beginning of the story?
Options: (A) To stop them fighting with each other. (B) To prevent her flowers being ruined. (C) To stop them stealing in the flower bed. (D) To keep the boy from being wounded.
Example Output: B

Example Input: Article: If you're into sports, you've seen it happen. You've probably even experienced it: basketball players shaking hands after four quarters of knocking each other around, tennis players leaping over the net to shake hands with their opponents after a hard-fought match, soccer players exchanging sport shirts after an intense 90 minutes, even boxers touching gloves at the beginning of each round, then hugging each other after beating each other into a pulp for 12 rounds. It seems like competitors in every event, from spelling bees to hockey, behave this way. What's going on? It's all part of sportsmanship, a great tradition in sports and competition that means playing clean and handling both victory and defeat with grace, style, and dignity. What is sportsmanship? Sportsmanship is defined as: playing fair, following the rules of the game, respecting the judgment of referees and officials, treating opponents with respect. Some people define good sportsmanship as the "golden rule" of sports --- in other words, treating the people you play with and against as you'd like to be treated yourself. You demonstrate good sportsmanship when you show respect for yourself, your teammates, and your opponents, for the coaches on both sides, and for the referees, judges, and other officials. But sportsmanship isn't just reserved for the people on the field. Cheerleaders and fans also need to be aware of how they behave during competition. Sportsmanship is a style and an attitude; and it can have a positive influence on everyone around you. Learning good sportsmanship means finding that the positive attitude learned on the field carries over into other areas of life. At school, for example, you're able to appreciate the contributions made by classmates and know how to work as part of a team to complete a project. You may enjoy more success at work as well, because a big part of learning good sportsmanship is learning to be respectful of others, including customers and co-workers.
