Answer :
Answer:
National borders made along the ethnic lines are much more stable, produce less conflict and hence are preferable.
Explanation:
Ethnicity pervades religion and slight variances in language but usually defines a culture. people of one ethnicity generally identify with one another through similarity of culture, customs and a sense of shared history. this helps in the creation of a homogeneous society with less conflict and more nationalism.
Countries not divided according to ethnicity like the arbitrarily carved out nations of Africa have often found themselves in civil wars due to divided loyalties and internal conflicts.
