Final answer:
The main causes of the Ethiopian famine in the 1980s did not include the war with Somalia, but were due to civil war, long drought, impoverished conditions, and poor government policies.
Step-by-step explanation:
The main causes of famine in Ethiopia in 1984 and 1986 include all of the following except war with Somalia. The famine in Ethiopia was caused by a multitude of issues including civil war, poverty, land tenure crises, and environmental challenges such as a long drought and poor soil quality. However, the war with Somalia directly contributing to the Ethiopian famine of the mid-1980s is not listed as a cause. Instead, Somalia was dealing with its own separate crisis characterized by civil war and famine that peaked around 1990. During the Ethiopian famine, the country was affected by the governmental policies of a one-party Communist state, massive uprisings, coup attempts, and a devastating drought that collectively led to more than a million deaths.
