One of the consequences of ethnic rivalries in African nations in recent years have been widespread civil conflict. With colonization, many European powers drew borders which had never previously existed and when de-colonization happened, many rival ethnic groups were mixed together or lived in areas where they had never previously lived together and this caused an uproar of tension. Some tribes were also favored by the European powers, while others were treated poorly and this continued to reinforce tension.
The correct answer is: "railroads".
Railroads flourished during the 19th century and enabled to travel long in-land distances much quicker than before. They were also one of the main factors that triggered the industrial revolution, as quick transportation reduced production costs and brought important efficiency gains for industries, for instance, in coal mining, and contributed to the development of mass production systems.
