Answer:
By causing some of the preexisting ethnic groups to become inferior and be ignored completely.
Explanation:
Culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
This ultimately implies that, culture are acquired and passed from one generation to another to form an ethnic group.
A superimposed boundary can be defined as the boundary imposed on a geographical region or area by a colonizing, conquering or an external power and as a result of this, the preexisting cultural organizations and patterns are completely ignored.
Some examples of a superimposed boundary is the geometric boundary between Uganda and Kenya, Iraq and Saudi Arabia, as well as other boundaries imposed on Africa by the Europeans during the era of colonialism.
<em>Hence, superimposed boundaries can lead to conflicts between pre-existing ethnic groups because it would cause the weaker ethnic groups among the preexisting ethnic groups to become inferior and greatly ignored due to the actions of a conquering or external ethnic group. </em>
