Example Input: Article: On a Friday night, a poor young artist stood at the gate of the New York railway station, playing his violin. The music was so great that many people stopped to put some money into the hat of the young man. The next day, the young artist came to the same place, and put his hat on the ground gracefully. Different from the day before, he took out a large piece of paper and laid it under his hat. Then he began to play the violin. It sounded more pleasant than ever. Soon he was surrounded with people who were attracted by the words on that paper. It said, "Last night, a gentleman named George Sang put an important thing into my hat by mistake. Please come to claim it soon." After about half an hour, a middle-aged man rushed through the crowd to the violinist and said, "Yes, it's you. I knew that you were an honest man and would certainly come here." The young violinist asked calmly, "Are you Mr. George Sang?" The man nodded. The violinist asked, "Did you lose something?" "It's a lottery ticket," said the man. The violinist took out a lottery ticket on which George Sang's name was seen. "Is it?" he asked. George nodded and took the lottery ticket and kissed it, then danced with the violinist. The violinist was a student at an arts college and had planned to attend advanced studies in Vienna. Later his classmate asked the violinist, "At that time you needed money to pay the tuition and you had to play the violin in the railway station every day to make money. Why didn't you keep the lottery ticket for yourself?" The violinist said, "Although I don't have much money, I live happily. But if I lose honesty I won't be happy forever." Through our lives, we can gain a lot and lose so much. But being honest should always be with us.

Example Input: Article: Outside her cottage, old Mrs. Taylor was hanging out laundry on a wire line, unaware that some children were hiding in a nearby tree watching her every move. They were determined to find out if she really was a witch. They watched nervously as she took a broomstick to sweep the dirt from her stone steps. But much to their disappointment, she didn't get on the broomstick and fly off. The old lady only looked up when her hen began to make sounds loudly --signaling that she had laid an egg in the nest on the top of the haystack. . The old lady put aside her broomstick and walked to the haystack, followed by Michael, a black cat she had rescued from a fox trap. With only three legs, it was hard for Michael to keep up with his mistress. The cat was proof for the children that only a witch would own a black cat with three legs! Crawling further along the branches, they could clearly see the haystack. Mrs. Taylor was standing on a wooden box with the new-laid egg in one hand. Placing the egg in her pocket, she readied herself to climb down. Then, without warning, the box broke under her and she crashed to the ground. The children were in horror. "Should we go and help her?" asked Mia. "What if it's a trick?" replied Patrick. "She probably knows we're here. Witches know things like that!" After thinking for a while, Julia said"Anyway, we should go and check whether she is all right." Approaching _ , they could see a wound on the old lady's forehead. She had knocked her head on a stone and was unconscious. "Go and get Dad," Mia yelled to her brothers. "Tell him about the accident." The boys didn't need another excuse to leave. They ran as fast as they could for help, hoping that Mrs. Taylor would not regain consciousness and turn the girls into frogs. Later, in the hospital, the old lady smiled her thanks. "I was so lucky that you lovely children happened to be passing when 1 fell. I must have yelled quite loudly." The children exchanged guilty glances, but were very pleased that she was not a witch after all!

Example Input: Article: It is probably the strangest sport anyone has ever invented.And at first sight,it looks like the easiest.Competitors have to do two things.The first is to stand still.The second is to place their hands anywhere on the body of a car,and keep it there. This is where things start getting difficult.Lots of people are doing the same thing.And the winner of the "handathon" contest is the person who can carry on doing it for the longest time.That person gets to own the car. It still seems to be an easy thing to do.At the beginning it is.Anyone can stand still.But when the contest has been going for four or five days,standing still seems like the most difficult job in the world.And keeping the hand in place over this time becomes an act of serious attention.After a few days,the hand seems to belong to someone else--someone who wants to go home and get some sleep. Competitors are allowed to take a five-minute break every hour to eat,drink or do whatever else is necessary.No one is allowed to lean on the car for support.Winners need to be able to show great powers of attention.They also need to be able to develop special skills. Maybe the popularity of the handathon is due to the fact that it is not necessary to be a trained athlete to enter.Entrants in the Longview handathon certainly don't seem to do much preparation.Most say they will prepare by "getting lots of sleep".Others say they will "eat healthy food" or "pray for success".The whole event gives ordinary people the chance to do something interesting and win something in the end. Handathons are competitions,but there is little rivalry between competitors.They help each other out and keep each other's spirits up.People who drop out early return with food,drink and encouragement.
