The U.S. Navy defends freedom, preserves economic prosperity, and keeps the ______ open and free.

• A. Seas
• B. Oceans
• C. Rivers
• D. Skies

Answer: (A)

The idea being tested is the Navy’s role in ensuring freedom of navigation across the world’s waters. Keeping the seas open and free refers to safeguarding sea lanes so ships can travel and conduct international trade without undue interference. This is a long-standing phrase and concept—freedom of the seas—central to naval doctrine and global commerce. While oceans is close in meaning, the common expression in this context is “the seas,” making it the natural fit. Rivers are inland waterways and not the global maritime domain the Navy primarily protects, and skies refer to airspace, which isn’t the focus of this statement.
