Step-by-step explanation:
Based on the passage from Federalist Paper #10 written by James Madison in 1787, Madison would support expanding the sphere or the size of the nation in modern political society. According to Madison, a larger and more diverse nation would make it less likely for a majority to have a common motive to invade the rights of other citizens. By including a greater variety of parties and interests, Madison believed that factions or special interests would be balanced and no single group would dominate the government.
