Which invention was most important in revolutionizing the meat industry?

A. air brakes
B. knuckle couplers
C. the Pullman car
D. the refrigerator car

Answer: D. the refrigerator car

The refrigerator car was the most crucial innovation in changing the meat industry. With it, perishable meat products could be transported long distances without spoiling. Before the refrigerator car, salting or canning meat was the only way to keep it from spoiling during transport. The refrigerator car brought fresh meat to a much larger market while lowering costs and waste. It also allowed the development of centralized meatpacking industries and expanded the national meat trade significantly (George S. May and Associates, LLC, Page 18). Ultimately, the answer is D, the refrigerator car.
