20. Read one of the following materials and answer the following questions. (6 points) Vauban is a small German town in Freiburg near the border between France and Switzerland.

(1) (Environmental Protection) Building Wobang Town is a beneficial attempt to realize sustainable development. The rapid development of global automobile industry has caused serious pollution to the environment. Building a car-free town in Wobang has greatly improved the air quality and people's living environment. Moreover, walking instead of riding in a small area is just a good exercise. So what it provides is undoubtedly a real modern civilized life that is beneficial to physical and mental health.

(2) (Modern Lifestyle) Efficient and convenient is a prominent feature of modern civilized life. Although the construction of Wobang Town is beneficial to environmental protection, it is not suitable for the fast-paced life of people today. In modern society, most people are busy with things and stress efficiency in everything. If there is no car, it will directly reduce the work efficiency for office workers, bring inconvenience to daily life and ultimately affect the quality of life. Therefore, Vauban-style towns are difficult to promote.

(3) (Modern Industrial Civilization) The automobile is a concentrated expression of modern industrial civilization. To build Wobang-style towns, it is forbidden to use cars within a certain range. Once this is popularized, the use of cars will be greatly reduced, which will objectively affect economic development and run counter to modern industrial civilization to some extent. Therefore, we need to be thoughtful and cautious.

You can grasp one of them for in-depth and thorough analysis, so as to avoid multiple and mixed opinions.
