23. Why did the McDonald brothers change the name of the restaurant and its menu? A. They were not having success. B. Their food was not selling well. C. They saw people wanted cheap and quick food. D. Ray Kroc made this suggestion to them.

The McDonald brothers realized that their original restaurant concept wasn’t maximizing efficiency or customer satisfaction, which led them to reinvent their menu to focus on speed and affordability. They wanted to capture the growing trend of people seeking quick meal options, especially in the post-war America where time was of the essence for many families. Ray Kroc, a milkshake machine salesman, played a pivotal role in their transformation. He saw the potential in their streamlined service and encouraged them to franchise the concept, which led to the widespread popularity of the McDonald's brand we know today. Kroc’s vision and business acumen helped propel McDonald's to global dominance, shaping the fast-food industry forever!
