Question: With more and more cars on the road, traffic jams are really a problem. Traffic jams can lead to increased accidents as there are more cars, with more people trying to get to their destination, all the while getting worse. Although it's impossible to avoid traffic jams altogether, there are some tips you can follow to reduce the amount of time on the road. Check for traffic jams before you leave. You can listen to the radio for traffic news, or check on the Internet to get up-to-minute information on traffic. If the way you want to take is heavy with traffic, you can choose another. Look for a different road all the time. Most traffic jams happen on busy roads. Using country roads could see you avoiding a lot of traffic. Although the distance you may have to travel is further, it can work out quicker. Set your car radio to receive traffic news. Many new car stereo systems are equipped with a radio system by which you can hear the traffic channel. This way you can get the latest traffic information and change your journey if necessary. Try traveling at different time. Most traffic jams usually happen during rush hour, so try to avoid this time period if possible. Some jobs offer flexible working hours so that you can travel to work outside of rush hour. Some jobs even allow you to work at home so as to avoid moving altogether. Ask your manager to see what you can do if traffic is a problem for you. Use public transportation where available. The easiest way to avoid traffic jams is to take buses or the underground instead of driving your own car. Not only will you avoid traffic jams but you will most likely be saving money as the cost rises. The author wrote the text in order to _ .

Question: The film stars out as a normal day at a typical American high school. Friends chat in the dining room and boys play football. But there's big surprise when the movie ends with two students going crazy in the school-shooting and killing people. This is Elephant. It stars real school kids. American director Gus Van Sant had no ready-made lines. The student actors made up their own dialogue, with Van Sant asking them to base their characters on their own lives. Although it may not sound very high quality, the film won the Palme d'Or for Best Film and the award for Best Director at the Cannes film festival. The film is based on the shootings at a high school in the US, where two boys killed 13 people and then themselves in 1999. The title of the movie refers to the old expression about a problem that's as hard to ignore as an elephant in the house. The film takes a close look at a few hours in the lives of the victims and the killers. It shows how high school is a different experience for everyone---fun and friendly, or hard and lonely. In many ways, the two boys, who carry out the shooting, act like ordinary kids. They joke around with one boy's mother as she serves them cakes and play the piano. But there're hints of the anger they feel inside. One of the boys is bullied at school. The other plays violent video games. But Van Sant isn't blaming their killings on either bullying or violent games. In fact, the film doesn't offer any reason for why school violence happens. "I didn't want to explain anything. It's up to the audience to draw its own conclusions," said the 51-year-old director. The film is named Elephant because _ . A) an elephant is always gentle and never causes trouble B) an elephant is a symbol of big problems in American schools C) elephant is used to suggest that the school crime is a big problem D) the two boys liked elephants when alive
Answer: C
