"Which Country Lies Closest to Capital?" — Insufficient Context

The question cannot be answered because the source text does not specify which capital or which country is being referenced. "Capital" could mean:

• A national capital (e.g., London, Paris, Washington)
• A state/provincial capital
• A historical capital
• A corporate/institutional headquarters

To answer, please provide the specific capital or context (e.g., "Which country lies closest to the capital of Mongolia?").
