听第10段材料,回答第17至20题。
If you only need to travel a short distance, the quickest way to travel in most cities is to walk. During working hours (between approximately 9:00 a.m. and 5:00 p.m. Monday through Friday), the traffic is very heavy on most city streets, sometimes, coming to a complete stop in places. As a result, many people prefer to walk. You should therefore be aware of some of the traffic laws. It is against the law in many cities to cross the street at any place except at the comer. These rules may not be followed as closely in small towns because the traffic is usually not so heavy. However, the purpose of the law is to provide for the safety and protection of the people. Remember to look both ways for automobiles when you cross the street.
What's the best way to travel a short distance in most cities？
[A] By car.
[B] On foot.
[C] By taxi.
