Example Input: Article: Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases(, ) with his students.The case at hand was a Guatemalan man, aged 34, who had a fever and many other medical problems.His condition was not improving, and there was not much hope he would live. Dr.: Mellinkoff asked to see the patient.He introduced himself in Spanish and, in a very gentle voice, asked how he felt.The patient smiled and said everything was all right.Then the doctor asked if he was able to eat.The patient said that he had no desire to eat. "Are you getting food you like?" The patient said nothing. "Do you get the kind of food you have at home?" The answer was no. The doctor put his hand on the man's shoulder and his voice was very soft. "If you had food that you liked, would you eat it?" "Yes, yes," the patient said. The change in the patient's appearance couldn't have been more obvious.Nothing was said, but it was easy to tell that a message had been sent and had also been received. Later, the doctor asked why the Guatemalan man wasn't getting food he could eat.One of the students said, "We all know how difficult it is to get the kitchen to make special meals." "Suppose," the doctor replied, "you felt a certain medicine was absolutely necessary but that our hospital didn't carry it, would you accept defeat or would you insist the hospital meet your request?" "I would probably insist," the student said. "Very well," the doctor said."You might want to try the same method in the kitchen.It won't be-easy, but I can help you.Meanwhile, let's get some food inside this man as fast as possible, and stay with it.Or he'll be killed by hunger.By the way, there must be someone among you who can speak Spanish.If we want to make real progress, we need to be able to talk with him." Three weeks later.Doctor Mellinkoff told me that the Guatemalan man had left the hospital under his own power.It takes more than medicine to help sick people; you also have to talk to them and make them comfortable.

Example Input: Article: One day a woman spotted a beggar sitting on the corner. The man was elderly, unshaven and ragged. Passers-by wanted nothing to do with him. But the woman smiled. "Are you hungry?" she asked. The man slowly looked up. This was a woman clearly used to the finer things in life. Her coat was new. She looked like that she had never missed a meal in her life. "No, " he answered sarcastically . "I've just come from dining with the president. Now go away. "To his surprise, the woman continued standing. And her smile became even broader. "What are you doing, lady?" he asked angrily. "I said to leave me alone. " Just then a policeman came up. "Is there any problem, ma'am?" He asked. "No problem here, officer," the woman answered. "I'm just trying to get this man to his feet. Will you help me?" The officer scratched his head. "That's old Jack. He's been around here for a couple of years. What do you want with him?" "See that cafeteria over there?" She asked. "I'm going to get him something to eat and get him out of the cold. " "Are you crazy, lady? I don't want to go in there!" Then the homeless felt strong hands lift him up. "Let me go, officer. I didn't do anything." "This is a good deal for you, Jack, "the officer answered. "Don't blow it. " Finally, the woman and the police officer got Jack into the cafeteria and sat him at a table. It was the middle of the morning, so most of the breakfast crowd had already left and the lunch bunch had not yet arrived. The woman turned to the officer, "Would you like to join us in a cup of coffee and a meal, officer?" "Yes, ma'am. That would be very nice. " Then, she sat down at the table across from her amazed dinner guest. She stared at him. "Jack, do you remember me?" Old Jack searched her face. "I think so --I mean you do look familiar. " "I'm Penelope Eddy. I'm a little older perhaps, "she said. "In my younger days when you worked here, I came through that very door, cold and hungry. " "I was just out of college, "the woman continued. "I had come to the city looking for a job, but I couldn't find anything. Finally _ and had been kicked out of my apartment. I walked down the streets, saw this place and came in to see if I could get something to eat. " Jack lit up with a smile. "Now I remember," he said. "I was behind the serving counter. " "You made me the biggest roast beef sandwich that I had ever seen and you paid for it out of your own money. " "I got a job that very afternoon. Eventually I started my own business. "She pulled out a business card. "When you are finished here, I want you to meet the personnel director of my company. I'm certain he'll find something for you to do around the office. " There were tears in the old man's eyes. "How can I ever thank you, "he said. "Don't thank me. "the woman answered. "Thank the Universe. It led me to you. " ks5u Outside the cafeteria, the officer and the woman paused at the entrance before going their separate ways. "Thank you for all your help, officer, "she said. "On the contrary, Ms. Eddy," he answered. "Thank you. I saw a miracle today, something that I will never forget. And thank you for the coffee. " She frowned. "I forgot to ask you whether you take sugar. That's black. " "Yes. I do. "the officer said. "But I don't need it now. I'm sure the coffee you bought me is going to taste as sweet as sugar. "

Example Input: Article: Miss Gogers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, "Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?" Tom at once answered, "Your brother. Because electricity travels faster than sound waves." "That's every good," Miss Gogers answered; but then one of the girls raised her hand, and Miss Gogers said. "Yes, Kate." "I disagree," Kate said. "Your brother would hear you earlier because when it's 11 o'clock here it's only 8 o'clock in Los Angeles."
