Question

what agency was established to regulate railroad rates across the nation?
○ interstate commerce commission
○ railroad regulatory bureau
○ farm protection bureau
○ national review board

Explanation:

The Interstate Commerce Commission (ICC) was established to regulate railroad rates and other aspects of interstate commerce, including railroads. The other options do not match this purpose: the Railroad Regulatory Bureau is not the correct historical agency, the Farm Protection Bureau is related to agriculture, and the National Review Board is unrelated to railroad regulation.

Answer:

A. Interstate Commerce Commission
