Câu 2:

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

Clean, Convenient, and Cheap

Big cities like New York and London have a lot of great things. They have museums, parks, shopping centres, and a huge variety of restaurants. However, there are a lot of annoying things in big cities. The most common problems are air pollution and noise.

Traffic is the main cause of air pollution and noise. For example, drivers in New York are famous for honking their horns and shouting. That noise drives many visitors crazy - it even drives a lot of the locals crazy, too. Other big cities have similar problems with their traffic.

City governments have a lot of pressure to solve these problems. The most common solution is public transportation. Public transportation is a form of travel provided by the government. For example, New York’s biggest form of public transportation is the subway.

Public transportation helps reduce these problems, but it is not enough. Another solution is bicycle sharing. This is a system that provides cheap bicycles. In cities that have bicycle sharing programmes, there are spots that have parked public bikes. People borrow the bikes and use them. They can drop off the bike at the same spot where they borrowed it, or they can drop it off at another spot.

Bicycle sharing programmes are different in each city. In some cities, the bikes are completely free. They are not even locked. In other cities, you have to pay a small deposit. You get the deposit back when you return the bike. In still other cities, you need to have a membership with the bicycle sharing programme. Once you have a membership with the bicycle sharing programme, you can use a bike at any time you want.

Bicycle sharing is hugely popular all over the world. People love this system because it is cheap, clean, and easy to use. There are bicycle sharing systems in dozens of countries and hundreds of cities. In total, there are more than 530 bicycle sharing systems around the world, and that number is going up all the time.

Which statement is true according to the passage?
