Question

what industry was most affected by the refrigerated railcar?
○ meatpacking
○ textile
○ farming
○ steel - making

Explanation:

Refrigerated railcars allowed for the transport of perishable goods, especially meat, over long distances without spoilage. The meatpacking industry relies on transporting fresh meat, so it was most affected. Textile, farming (in the sense of raw crop transport, not as directly perishable - focused as meat), and steel - making industries don't rely on refrigerated transport for their core products as meatpacking does.

Answer:

A. meatpacking
