Take the following as truth: The Loire is the longest river in France ' flowing an impressive 1,010 km (630 miles) from its source in the Vivarais mountains south of Saint-Etienne to its estuary west of Nantes ' but the region of the most interesting chateaux, from Chambord to Angers, covers barely a fifth of that distance.
Then the following statement: "France's longest river is the loire." is true, false, or inconclusive?
