Input: Consider Input: Article: In the 19thcentury, Americans from the eastern states moved out west to settle in the rich new lands along the Pacific Coast. The most difficult part of their trip was crossing "the Great American Desert" in the western part of the United States by horse and wagon. The western desert can be very dangerous. There is little water and there are few trees. But the desert also has scenery of great beauty. Tall towers of red and yellow stone rise sharply from the flat, sandy valley floor. The scene has been photographed many times and appears in movies and on TV. In Arizona, man-made dams across the Colorado River have made two large lakes in the middle of the dry desert country. At Lake Powell, the red stone arch of Rainbow Bridge rises high above the blue lake. There are few roads. Many areas of Lake Powell's shore can only be reached by boat or on foot. But hikers in this empty desert land sometimes find very old native American pictures, painted on the rocks. In Death Valley, California, the summer temperature rises to 130degF--165degF. There is less than inches of rain each year. Death Valley is the lowest place in America---925 metres below sea level. In the 1800s, many travelers died when they tried to cross this waterless valley in the terrible heat. Although the desert is dry and seems empty, there is plenty of life if you look closely. Snakes and rats have learned how to live in the desert heat. They live underground and come out at night, when it is cool. Plants such as cacti need very little water. When it does rain in the desert (sometimes only once or twice a year), plants grow quickly, and flowers open in a single day. For a short time, the desert is covered with brilliant (very bright) colours.

Input: Consider Input: Article: Do you know how to play a game called "Musical Chairs"?It is easy to play and most people enjoy it. All you need are some chairs, some people and some way of making music. You may use a piano or any other musical instrument, if someone can play it. You may use a tape recorder. You can even use a radio. Put the chairs in a row. The chairs may be put in twos, back to back. A better way is to have the chairs in one row with each chair facing in the opposite direction to the chair next to it. The game is easy. When the music starts, the players walk round the chairs. Everyone goes in the same direction, of course, they should walk in time to the music. If the music is fast they should walk quickly. If the music is slow, they should walk slowly. The person playing music cannot see the people in the game. When the music stops, the players try to sit on the chairs. If a person cannot find a chair to sit on, he drops out. Then, before the music starts again, one chair must be taken away. When the music stops again, one more player will be out.. At last, there will be two players and one chair. The one who sits on the chair when the music stops is the winner.
Answer: nine chairs

Output: If ten people are playing musical chairs,you must begin with _ .

Input: Consider Input: Article: Miss Popular I was awkward in middle school: bony and athletic, with a high grade in science and a low one in self-esteem. Though I had a few friends, I wasn't popular. I was picked last in football and I sometimes ate lunch by myself. I remember the day Brittany came to our school. Her teeth were crooked , and she was a little overweight. Not that this mattered though, because she walked around like she was better than all of us. She was outspoken and incredibly frightening, making people lose confidence. Around Brittany, I tried my best to go unnoticed. Standing out or stealing her spotlight could only result in one thing: conflict. Brittany was always the first girl picked for teams; I was lucky if I was picked at all. I was thrown the ball while she stood with the quarterback, chatting about the last party she'd gone to. I had never been to a party before or kissed a boy. One day, a classmate asked me to the school dance. I was flattered. Then Brittany told me during science class that she had persuaded him to invite me. She asked in front of everyone, "Why would anyone even want you?" I went home and cried. Although she was seemingly perfect in everyone's eyes, I wanted to be everything that she wasn't and yet a million times more perfect. Brittany was so frightening and violent, but I wanted to be calm and not at all aggressive. I found Brittany's online profile a few weeks ago. She still had the same chubby face and mocking simile, and had posted half-naked pictures of herself. But as I read on, I realized that Brittany had died in a drunken driving accident a year ago. She had been 16 and pregnant at the time. Suddenly my view of Brittany changed from a bad influence into a struggling little girl whose life was taken before she could understand right from wrong. My experience with Brittany taught me that though we are all innocent in our youth, the choices we make will have great effects on us forever. I will always remember Brittany as that loud, overconfident girl. As part of that shy insecure person I used to be will always keep me modest.
Answer: the author was trying to avoid conflict with Brittany
Output: From the first three passages we can conclude that _ .
