Questions 25 to 29 are based on the following passage. Worldwide, 40 million new passenger cars are built every year. A recent survey estimates that the number of cars will triple over the next 20 years. Most of this growth will take place in China. In comparison, the United States has been completely transformed by cars. Cars did not become necessities for families in the United States until after World War II. Prior to that time, cars were seen mainly as toys for the rich. By the end of the war, however, people were tired of saving their money. They were ready to have some fun. Unlike Europe and Japan, whose industries had been wiped out by World War II, factories in the United States could quickly be changed from production of wartime items to mass production of such luxury items as cars. As cars grew in popularity in the United States, there were also changes in lifestyle. Farmers who were once isolated from society by rural life now took weekend trips into the city. Also, workers in the cities no longer needed to live in inner-city housing in order to keep their jobs at nearby factories. Those who made enough money moved out of the cities and into the suburbs. Now that each family had its own car, going to work from the suburbs became a common practice. Cars not only changed the way people lived, but also changed the way they thought. Traditionally, because young people spent most of their time outside school in and around the home, the strongest role models for teenagers were their parents. However, once they had access to their own cars, teens began spending more time out with friends. Therefore, they became less likely to follow the behavior of their parents and more likely to follow their friends’. One thing producers paid little attention to, however, was safety. It wasn’t until the mid-1960s that consumers began to demand that all car companies include at least a few common safety features in new cars. These new standards eventually led to safety features such as seat belts, air bags, anti-lock brakes, and automatic door locks. 25. Why cars didn’t sell as well in Europe as in the United States?
