Which canal's construction dramatically altered U.S. military and commercial power?

• A. Panama Canal
• B. Suez Canal
• C. Erie Canal
• D. Kiel Canal

Answer: (A)

The main idea being tested is how a canal can reshape a nation’s ability to move its military forces and control global trade by shortening sea routes between oceans. The Panama Canal does this most dramatically: it links the Atlantic and Pacific, letting the U.S. Navy move ships quickly between coasts and project power across the globe without the long detour around South America. That rapid mobility strengthened the United States’ military reach and vulnerability to crises anywhere along the world’s sea lanes, while also boosting international commerce by cutting transit times and costs. The Suez Canal shifted global trade patterns and the Erie Canal boosted domestic commerce, but neither changed the United States’ military mobility and strategic reach to the same extent. The Kiel Canal is a German waterway with little relevance to U.S. power.
