Concept:Refugees are people who flee their home country because of war, danger, or persecution.
Explanation:Liberia experienced a long period of civil war and severe ethnic conflict.
These conditions caused great suffering and made life unsafe for many Liberian citizens.
As a result, large numbers of Liberians moved to other West African countries, including Ghana, to find safety.
Higher wages in Ghana, loss of markets in Liberia, or food shortage caused by overpopulation are not the primary reasons for a refugee movement.
Such economic factors do not make people abandon their homeland in large numbers.
The main cause of the refugee influx is the widespread suffering and insecurity from ethnic tension and civil war.
Answer:D. great suffering in Liberia from ethnic tension and civil war
