单选题Questions 57 to 60 are based on the following passage: 　　In 1939 two brothers, Mac and Dick McDonald started a driven-in restaurant in San Bemardino, California. They carefully chose a busy comer for their location. They had run their own businesses for years, first a theater, then a barbecue restaurant, then another driven-in, but in their new operation, they offered a new, shortened menu: French fries, hamburgers, and sodas. To this minimal selection they added one new concept: quick service, no waiters or waitresses, and no tips. Their hamburgers sold for fifteen cents. Cheese was another four cents. Their French fries and hamburgers had a remarkable uniformity, for the brothers had developed a strict routine for the preparation of their food, and they insisted on their cooks' sticking to that routine. Their new drive-in became incredibly popular, particularly for lunch. People drove up by the hundreds during the busy noontime. The self-service restaurant was so popular that the brothers had allowed ten copies of their restaurant to be opened. They were content with this modest success until they met Ray Kroc. Kroc was a salesman who met the McDonald brothers in 1954, when he was selling milkshake-mixing machines. He quickly saw the unique appeal of the brothers' fast-food restaurants and bought the right to franchise other copies of their restaurants. The agreement struck included the right to duplicate the menu, the equipment, even their red and white buildings with the golden arches. TodayMcDonald's is literally a household name. Its names for its sandwiches have come to mean hamburger in the decades since the day Ray Kroc watched people rush up to order fifteen-cent hamburgers. In 1976, McDonald's had over $1 billion in total sales. Its first twenty-two years is one of the most incredible success stories in modern American business history.
