If paid movement runs past the end of its terrain, where does the Scout stop?

Question

Accepted Answer

The Scout stops at the last space of that terrain, and the surplus movement is lost. Food movement, for example, stops at the last river space before the mountains. Each resource's movement is used on its own terrain, and anything left over is lost before the next terrain type.
