Q1. Why is Ukraine listed as the second-largest country in Europe? France is. (Or alternately, Denmark is.)
It's an ambiguous statement, and depends on whether you include non-European territories or not, and whether you include disputed territories or not. The totality of France (which includes
French Guiana) is larger than Ukraine, but the European part of France (
Metropolitan France) is smaller than Ukraine. Although Denmark is in Europe, Greenland is in North America.
