Example Input: Article: In my procession as an educator and health care provider, I have worked with numerous children infected with the virus that causes AIDS. The relationships that I have had with these special kids have been gifts in my life. They have taught me so many things, but I have especially learned that great courage can be found in the smallest of packages. Let me tell you about Tyler. Tyler was born infected with HIV: his mother was also infected. From the very beginning of his life, he was dependent on medications to enable him to survive. When he was five, he had a tube surgically inserted in a vein in his chest. This tube was connected to a pump, which he carried in a small backpack on his back. Medications were hooked up to this pump and were continuously supplied through this tube to his bloodstream. At times, he also needed supplemented oxygen to support his breathing. Tyler wasn't willing to give up one single moment of his childhood to this deadly disease. It was not unusual to find him playing and racing around his backyard, wearing his medicine-laden backpack and dragging his tank of oxygen behind him in his little wagon. All of us who knew Tyler marveled at his pure joy in being alive and the energy it gave him. Tyler's mom often teased him by telling him that he moored so fast she needed to dress him in red. That way, when she peered through the window to check on him playing in the yard, she round quickly spot him. This dreaded disease eventually wore down even the likes of a little dynamo like Tyler. He grew quite ill and, unfortunately, so did his HIV-infected mother. When it became apparent that he wasn't going to survive, Tyler's mom talked to him about death. She comforted him by telling Tyler that she was dying too, and that she would be with him soon in heaven. A few days before his death, Tyler beckoned me over to his hospital bed and whispered, "I might die soon. I'm not scared. When I die, please dress me in red. Mom promised she's coming to heaven, too. I'll be playing when she gets there, and I want to make sure she can find me."
Question: What is the boy Tyler's attitude towards death?
Options: (A) pessimistic. (B) optimistic. (C) sorrowful. (D) fearful.
Example Output: B

Example Input: Article: A man came home from work late, tired and irritated, to find his 5-year-old son waiting for him at the door. "Daddy, may I ask you a question?" "Yeah sure, what is it?" replied the man. "Daddy, how much do you make an hour?" "That's none of your business. Why do you ask such a thing?" the man said angrily. "I just want to know. Please tell me. How much do you make an hour?" pleaded the little boy. "If you must know, I make $20 an hour." "Oh," the little boy replied, with his head down. Looking up, he said, "Daddy, may I please borrow $10?" The father was furious, "If the only reason you asked that is so you can borrow some money to buy a silly toy or some other nonsense, then you march yourself straight to your room and go to bed. Think about why you are being so selfish. I don't work hard every day for such childish behavior." The little boy quietly went to his room and shut the door. The man sat down and started to get even angrier about the little boy's questions. How dare he ask such questions only to get some money? About an hour or so, the man had calmed down, and started to think: maybe there was something he really needed to buy with that $10 and he really didn't ask for money very often. The man went to the door of the little boy's room and opened the door. "Are you asleep, son?" He asked. "No daddy, I'm awake," replied the boy. "I've been thinking, maybe I was too hard on you earlier," said the man. "It's been a long day and I took out my aggravation on you. Here's the $10 you asked for." The little boy sat straight up, smiling. "Oh, thank you, daddy!" he yelled. Then, reaching under his pillow he pulled out some crumpled up bills. The man, seeing that the boy already had money, started to get angry again. The little boy counted out his money, then looked up at his father. "Why do you want more money if you already have some?" the father grumbled. "Because I didn't have enough, but now I do," the little boy replied. "Daddy, I have $20 now. Can I buy an hour of your time? Please come home early tomorrow. I would like to have dinner with you."

Options: (A) was very happy (B) answered him immediately (C) was not willing to tell him (D) didn't tell him at all
Example Output: C

Example Input: Article: Since the beginning of time, man has been interested in the moon. The Romans designed a special day to show admiration and respect to the moon. They called it "Moonday", or "Monday", as we know it today. Later, the great mind of Leonardo da Vinci studied the moon and designed a machine to carry a human to the moon. Leonardo said that one day a great machine bird would take a person to the moon and bring great honour to the home where it was born. Four and a half centuries later, Leonardo's idea was realized. Apollo II took three Americans--Collins, Aldrin, and Armstrong--to the moon. The mission did fill the whole world with great surprise, as Leonardo had said it would. A lot of essays, articles, and books were written about man's first moon mission. But perhaps the most interesting story was one written before the event----over 100 years before. In 1865, French author Jules Verne wrote a story about the first journey to the moon. His story was very similar to the 1969 Apollo II mission. Verne's spacecraft also contained three men--two Americans and a Frenchman. The spacecraft was described as being almost the same size as Apollo II. The launch site in Verne's story was also in prefix = st1 /Florida. The spacecraft in Verne's story was named the "Columbiad". The Apollo II command ship was called "Columbia". His account of sending the spacecraft into the space could easily have been written about how Apollo II was sent into the space. Verne's story was the same as the actual event in several other respects. The speed of Verne's spacecraft was 36,000 feet per second; Apollo's was 35,533 feet per second. Verne's spacecraft took 97 hours to reach the moon; Apollo's time was 103 hours. Like Apollo's spacemen, Verne's spacemen took pictures of the moon's surface, relaxed on their seats, cooked with gas, and experienced weightlessness. They too came down in the Pacific and were picked up by an American warship. What were the reasons for Jules Verne's extreme accuracy in describing an event 100 years or more before it actually occurred? He based his writings on the law of physics and astronomy . Nineteenth-century science and the vivid Verne's imagination gave people an unbelievably accurate preview of one of the greatest events of the 20thcentury.
