Question

how can political instability make genocide more likely?
by causing hardships and famine for the general population
by encouraging those who disagree to live together in a part of the city
by creating an unequal distribution of power between groups
by causing courts to punish members of certain groups

Explanation:

Political instability can lead to power - struggles. When there is an unequal distribution of power between groups, it can create an environment where one group may target another for elimination, increasing the likelihood of genocide. Hardships and famine don't directly link to genocide as strongly as power - imbalance. Encouraging disagreement in a living area is not a typical cause of genocide. Courts punishing certain groups is more a symptom of an already unequal power situation rather than a direct cause of the likelihood of genocide.

Answer:

by creating an unequal distribution of power between groups
