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 from 37 to 41.

        In the future, cities will need to grow in a good way and not damage the environment. People who manage cities in the future will have to consider a large number of things, including transportation, energy use and green spaces. All of these will need to be improved to make future cities pleasant places to live. 

        Smart systems will run successful future cities, including self-driving vehicles powered by eco-friendly fuels, such as electricity produced by solar panels or wind power. Transportation by car within the city will actually be faster than now, because there will be less congestion. A lot more people will commute to and from work on subway systems and in buses with their own lanes. Most trucks will disappear from city streets because delivery of goods will be by drone. 

         Successful future cities will have a lot more green spaces than today, which will improve air quality and reduce, to some extent, the worst effects of climate change. Research has shown that green spaces improve mental health as well as physical health, so the people who live in these cities will generally be happier than today. Although it will be expensive, new parks must be built. In addition, green spaces will also be put on top of buildings, private and public, and trees will be planted alongside all streets.
