Read about traffic problems in two cities. Match the city with its problem.
|
A. Ho Chi Minh City |
In Ho Chi Minh City, it is not strange to see the sight of a street that is crowded with vehicles. People cannot move and their health is affected by polluted air from exhausted fumes. What are the reasons? The citizens in the city use many personal vehicles to go from one place to another. They aren't used to transporting by public transports. May be because the bus drivers are careless, impolite to them or the taxi fare is too high for some people.
Bangkok is world renowned for its terrible traffic problems, so getting around on the roads is a bit of a nightmare. In my opinion, there are 3 main causes of Bangkok traffic jams. First, the quality of public transportation is low. Bus is of low quality and causes congestion. Second, the BTS and MRT are not enough for users. Finally, the most important cause of traffic jam is car accidents. Bad bus drivers cause accidents frequently and make the road stuck for hours.
PROBLEMS
1. It has low quality public transport: B. Bangkok.
2. It costs a lot to go by taxi: A. Ho Chi Minh City.
3. There are not enough MRTs for its inhabitants: B. Bangkok.
4. Its citizens use a lot of personal vehicles: A. Ho Chi Minh City.
5. There is a high frequency of accidents: B. Bangkok.
