Input: Consider Input: Article: The first day my new teacher walked into our school in Spanish Harlem, I burst out laughing. Ron Clark was a young white guy from North Carolina who talked with a funny Southern accent . He said he used to be a singing waiter. I thought, who is this guy? He's a complete joke. It was 1999 and I was in the fifth grade at New York City's P.S. 83. _ . I'd always been a troublemaker. I'd get yelled at, and then the teachers would give up on me. I thought that's what would happen with Ron Clark. I was wrong. That first week, I kept mocking him. He pulled me out to the hallway and said I'd better shape up. "Tamara," he said, "you're a smart kid. You can do better." He told me I was a natural leader and that I'd go far in life if I started applying myself. I was mad at first, but then something happened: I began to respect him. There were 29 students in our class, and it didn't take long for us to realize that Ron Clark was no ordinary teacher. He was only 27 and had the most unusual way of teaching. To help us learn the states and capitals, he changed the lyrics of a popular rap hit called "Thong Song" and had us sing and dance with him. When we read the Harry Potter books, he decorated our classroom like Hogwarts. And during the Presidential election, he put campaign posters on the walls and covered the room with 5,000 red, white and blue stars.
Question: What's the author's attitude toward the new teacher on the first day?
Options: (A) Excited. (B) Disappointed. (C) Appreciative. (D) Disdainful .

Output: D

Input: Consider Input: Article: Handshaking, though a European practise is often seen in big cities of China. Nobody knows exactly when the practice started in Europe. It is said that long long ago in Europe when people met, they showed their unarmed hands to each other as a sign of goodwill. As time went on and trade in cities grew rapidly, people in cities began to clap each other's hands to make a deal or to reach an agreement. This practice was later changed into shaking hands among friends on meeting or leaving each other. "Let's shake (hands) on it" sometimes means agreement reached. Do the Europeans shake hands wherever they go and with whomever they meet? No. Sometimes the Chinese abroad reach out their hands too often to be polite. It is really very impolite to give your hand when the other party, especially when it is a woman, shows little interest in shaking hands with you and when the meeting does not mean anything to him or-her. Even if, for politeness, he holds out his unwilling hand in answer to your uninvited hand, just touch it slightly- There is generally a misunderstanding among the Chinese that westerners are usually open and straighforward, while the Chinese are rather reserved in manner. But in fact some people in western countries more reserved than some Chinese today. So it is a good idea to shake hands with a westerner only when he shows interest in further relations with you.
Question: In the old days in Europe, people put out their unarmed hands to each other _ .

Input: Consider Input: Article: Trapped on the 37thFloor Melinda Skaar wasn't expecting any phone calls. Skaar was working late in her office at the First Internet bank of California. By 10:45 that night she was almost ready to go home when the phone rang. Picking it up, she heard a guard shouting. There is a fire! Get out of there. Skaar didn't panic. She figured that it was just a small fire. Her office building was huge. There were 62 floors and her desk was on the 37thfloor. Skaar called out to office mate Stephen Oksas, who also stayed late to work. But when they got out to the hallway, they were met by a cloud of black smoke. Rushing back, Skaar shut the door and filled the space at the bottom of the door with her jacket to keep the smoke out. Then they called 911. before they could call their families, however, the line went dead. That meant that they were completely cut off from the outside world. All they could do was wait and hope someone would come to rescue them. Minutes ticked by. Smoke began to float into the office. Soon it became hard for them to breathe. Looking around, Skaar noticed a small workroom. It seemed to have cleaner air. So they crowed there. That helped for a while, but in time even the workroom was filled with deadly smoke. Hopeless, they tried to break the windows, but the glass was not breakable. Everything they threw at just bounced back. Defeated, they struggled back to the workroom. They felt weak and dizzy. Soon Skaar found Oksas had passed out. Skaar and Oksas knew they were lucky to be alive. Sunday is my birthday, Skaar told a reporter. She would be turning 29. but she knew she had already got the best present possible----the gift of life.
Question: What did Skaar and Oksas do where were stopped by the fire?
Options: (A) they called their families (B) they waited where they were (C) they tried to run down the stairs (D) they rushed back and shut the door
Output: D
