Final answer:
Madison argues that two features, checks and balances and the rule of law, should be present in a government practicing separation of powers to preserve the people's liberty.
Step-by-step explanation:
James Madison argues that in a government that practices separation of powers, two features should be present in order to preserve the liberty of the people: checks and balances, and the rule of law.
Checks and balances refer to the system of each branch of government having the ability to limit and control the power of the other branches. This ensures that no one branch becomes too powerful and that the government functions in a balanced manner.
The rule of law means that everyone, including government officials, is subject to and must obey the law. This principle helps prevent the abuse of power and ensures fairness and equality for all individuals.
