Some political thinkers hope to devise a form of government in which every citizen' s rights are respected. But such a form of government is impossible. For any government must be defined and controlled by laws that determine its powers and limits; and it is inevitable that some individuals will learn how to interpret these laws to gain a greater share of political power than others have. Which one of the following is an assumption required by the argument? ["In any form of government, if anybody gains a greater share of political power than others have, then somebody's rights will be violated.", "A government can ensure that every citizen's rights are respected by keeping the citizens ignorant of the laws.", 'In any form of government that leads to unequal distribution of political power, the rights of the majority of people will be violated.', 'People who have more political power than others have tend to use it to acquire an even greater share of political power.']
