With the development of China's economy, the entry of private cars into families is no longer a distant dream for the Chinese. However, with the increasing number of private cars, the already severe traffic tension will be exacerbated. Therefore, China's transportation problems will ultimately limit the development of private cars. Which of the following, if true, would best refute the above view? ['Develop transportation first, and then the car industry.', 'The increase in private cars is not the main cause of increased traffic tensions.', "As cars enter the home, it will inevitably lead to the development of China's transportation. There is always a car first and then a road.", 'In China with a large population and underdeveloped transportation, it is impractical to develop a private car.']
