The correct answer is C) Cities like Chicago prospered because they were railroad hubs.
A result of the rise of the railroad industry was that cities like Chicago prospered because they were railroad hubs.
When the Railroad Act of 1862 allowed for the construction of a transcontinental railroad, it represented good news for business. The government gave this task to the Union Pacific Railroad and the Central Pacific to connect the East of the United States with the West. They worked for seven years to finally connect Sacramento, California with Omaha, Nebraska. The railroads connected in Promontory Utah on May 10, 1869. This allowed larger cities to grow and prosper due to trade and better transportation of goods and people.
