Read the following passage and answer these questions: For many people, commuting by car or by public transportation is a daily necessity. People with their own cars, use it to commute to work, to go shopping or to take the family out on weekends. For those who cannot drive or afford to buy their own vehicles, public transportation provides these commuterswith their only means of transportation. However, it seems that it won't be too long before our society will have to resort back to the horse and buggy cart era if our politicians don't build better roads or resolve the on-going oil crisis. Our roads and highways are crowed most of the time,especially in rush hour.Heavy traffic and poorly designed roads are all factors that can lead to a slow down in traffic flow.A lot of construction work that takes place along our roads and highways are actually worsening the traffic problem worse than providing a better solution to it. 1.What do people do with their own vehicles? 2.How do people without private vehicles travel to work? 3.Why may vehicles not be used any more? 4.Why are roads and highways crowded? 5.What may lead to a slow down in traffic flow?
