Do four colors really suffice? Suppose this map shows the provinces of a country. peculiarity of this country is that it has one province comprised of two separate pieces the striped regions. Thus when coloring this map, a cartographer must use the same color on these two separate pieces. Is it possible to complete the coloring using only four colors? Does this suggest a need to clarify the Four Color Theorem?

30. Do four colors really suffice? Suppose this map shows the provinces of a country. A
peculiarity of this country is that it has one province comprised of two separate pieces,
the striped regions. Thus when coloring this map, a cartographer must use the same
color on these two separate pieces. Is it possible to complete the coloring using only
four colors? Does this suggest a need to clarify the Four Color Theorem?
