Characteristic examples were mining and smelting and the woolen industry. The rapid development of these enterprises was stimulated by technical advances, such as the invention of the spinning wheel and the discovery of a new method of making brass, which saved about half of the fuel previously used.

[单项选择]Fast food, a mainstay of American eating for decades, may have reached a plateau in the United States as the maturing baby-boom generation looks for a more varied menu. Fast foxed still represents a $102 billion a year industry, but growth has turned sluggish recently amid tough competition from retail food stores and a more affluent population willing to try new things and spend more, analysts say. Signs of trouble in fast food include price-cutting by industry leaders, including efforts by McDonald’s to attract customers with a 55 cent hamburger, and major players pulling out or selling. O’Pepsico, for example, is selling its fast-food restaurant division that includes Taco Bell, Pizza Hut and KFC.
"It’s becoming harder and harder for these firms to grow," said Jim Brown, a professor of marketing at Virginia Tech University. "I think in the United States fast food has reached a saturation (饱和) point because of the number of competitors and the number of outlets."
Fast-f
A. Customers’ demand and competition with retailers.

C. Competition with retailers and diversity of food.
D. Customers’ demand and the aging of baby-boomer.
