Question

which of the following is an example of genocide?○ segregation of ethnic groups○ mass killing of one ethnic group○ poor treatment of one ethnic group○ u.n. forces moving into a country

Explanation:

Genocide is defined as the deliberate and systematic destruction, in whole or in part, of an ethnic, racial, religious, or national group. Mass killing of an ethnic group directly fits this definition, while segregation, poor treatment, and UN forces entering a country do not meet the criteria of systematic group destruction.

Answer:

mass killing of one ethnic group
