Base on my research, the African colonies are characterized by the lack of services, non-representative governments, larger police forces and worst is the forced labor. These are the style of the European rule during the so-called "THE AFRICAN COLONIES OF GERMANY AND THE WAR" from the journal article of Adams C. C. (Jun. 1916).

The answers are:
