input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: The first kind of air transportation was not a plane. It was a balloon. People traveled by balloon 100 years before there were planes or jet aircraft. Those early days of ballooning were exciting, but they were also dangerous. Sometimes the balloons fell suddenly. Sometimes they burned. However, the danger did not stop the balloonists. The first real balloon flight was in France in 1783. Two Frenchmen, the Montgolfier brothers, made a balloon. They filled a very large paper bag with hot air. Hot air is lighter than cold air, so it goes up. The Montgolfier's hot air balloon went up 1,000 feet in the sky. Later that same year, two other Frenchmen ascended in a basket under a balloon. They built a fire under the balloon to make the air hot. This made the balloon stay up in the air for a few hours. But their balloon was tied to the ground. So it could not go anywhere. The first free balloon flight was in December, 1783. The balloon flew for 25 minutes over Paris. It traveled about 5.5 miles. Flying a balloon is not like flying a plane. The balloon has no engine and therefore no power of its own. The wind directs the balloon. It goes where the wind blows. The pilot can control only the altitude of the balloon to find the right wind direction. That is how a good pilot controls where the balloons goes. Soon balloonists tried longer flights. A major event in the history of ballooning was the first long flight over water. In 1785, an American and a Frenchman flew over the English Channel. During the nineteenth century, ballooning became a popular sport. There were balloon races in Europe. Balloons were also used by scientists to study the air and by armies in wartime. After the airplane was invented, people lost interest in balloons. Planes were much faster and easier to control. But some people today still like to go up in balloons. High up in the balloon basket, they find quietness. They have wonderful view of the world below. Options: A a jet plane B an aircraft C a balloon D a ship Answer: C a balloon Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: A nurse took the tired, anxious serviceman to the bedside. "Your son is here,"she said to the old man. She had to repeat the words several times before the patient's eyes opened. Heavily drugged with sleep because of the pain of his heart attack, he dimly saw the young uniformed Marine standing outside the oxygen tent. He reached out with his hand. The Marine wrapped his toughened fingers around the old man's weak ones, expressing a message of love and encouragement. The nurse brought a chair so that the Marine could sit beside the bed. All through the night the young Marine sat there in the poorly lighted ward , holding the old man's hand and offering him words of love and strength. Occasionally, the nurse suggested that the Marine move away and rest a while. He refused. Now and then she heard him say a few gentle words. The dying man said nothing, only holding tightly to his son all through the night. Along towards dawn, the old man died. The Marine released the now lifeless hand he had been holding and went to tell the nurse. While she did what she had to do, he waited. Finally, she returned. She started to offer words of sympathy, but the Marine interrupted her."Who was that man?"he asked. The nurse was surprised. "He was your father,"she answered. "No, he wasn't,"the Marine replied. "I never saw him before in my life.""Then why didn't you say something when I took you to him?"asked the nurse. "I knew right away there had been a mistake, but I also knew he needed his son, and his son just wasn't here. When I realized that he was too sick to tell whether or not I was his son, knowing how much he needed me, I stayed."he answered. Options: A Because he was the old man's son. B Because she knew that he was a warm-hearted man. C Because she couldn't find anyone else there. D Because she thought he was the old man's son. Answer: D Because she thought he was the old man's son. Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Acting is such an over-crowded profession that the only advice that should be given to a young person thinking of going on the stage is "Don't!". But it is useless to try to discourage someone who feels that he must act, though the chances of his becoming famous are slim. The normal way to begin is to go to a drama school. Usually only students who show promise and talent are accepted, and the course lasts two years. Then the young actor or actress takes up work with a repertory company, usually as an assistant stage manager. This means doing everything that there is to do in the theatre: painting scenery, looking after the furniture, taking care of the costumes, and even acting in very small parts. It is very hard work indeed. The hours are long and the salary is tiny. But young actors with the stage in their blood are happy, waiting for the chances of working with a better company, or perhaps in films or television. Of course, some people have unusual chances which lead to fame and success without this long and dull training. Connie Pratt, for example, was just an ordinary girl working in a bicycle factory. A film producer happened to catch sight of her one morning waiting at a bus stop, as he drove past in his big car. He told the driver to stop, and he got out to speak to the girl. He asked her if she would like to go to the film studio to do a test, and at first she thought he was joking. Then she got angry and said she would call the police. It took the producer twenty minutes to tell Connie that he was serious. Then an appointment was made for her to go to the studio the next day. The test was successful. They gave her some necessary lessons and within a few weeks she was playing the leading part opposite one of the most famous actors of the day. Of Course, she was given a more dramatic name, which is now world-famous. But chances like this happen once in a blue moon! Options: A actors are very unusual people B the course at the drama school lasts two years C acting is really a hard job D there are already too many actors Answer: D there are already too many actors Question:
