【单选题】

Unlike theirAmerican orEuropean counterparts, car salesmen in Japan work hard to get a buyer. Instead of wandering around showrooms waiting for customers to drop by, many Japanese car salesmen still go out to get them. They walk on the streets selling cars door-to-door. New customers are hunted with a vengeance and existing ones entertained with fruit and cakes on their birthdays.But life is getting tough—and not just because new-car sales are falling.

With more Japanese women (who often control the household budget) going out to work, the salesmen increasingly find nobody at home when they call. That means another visit in the evening or at the weekenD、Then they face an extra problem: more people, especially the young, prefer to choose a new car from a showroom where they can compare different models.
Even as late as the mid-1980s some 90% of new cars were sold door-to-door. In some rural areas most new cars are still sold this way.But in the big cities more than half the new cars are now sold from showrooms.
Although investing in showrooms is expensive because of the high cost of Japanese land, dealers have little choice.
A、labor shortage and higher expectations among Japan’s workforce are making it difficult to recruit door-to-door salesmen. Most of a Japanese car salesman’s working day is spent doing favors for customers, like arranging insurance or picking up vehicles for servicing, rather than actually selling.
Japan’s door-step car salesmen are not about to vanish. The personal service they provide is so deep-rooted in Japan that they are likely to operate alongside the new showrooms. The two systems complement each other. What increasingly happens is that the showroom attracts the interest of a potential buyer, giving the footsore salesmen a firm lead to follow up with a home visit.
The one reason why dealers’ life is getting tough is that ______.
A、new car sales are falling
B、Japan is in recession
C、car prices are increasing fast
D、high inflation has dented the customers’ purchasing power
