Final answer:
This article discusses dual federalism, cooperative federalism, categorical grants, and block grants in the United States.
Step-by-step explanation:
Dual federalism, cooperative federalism, categorical grants, and block grants are all types of federalism and forms of intergovernmental relationships in the United States.
Dual federalism is a style of federalism where the states and national government exercise exclusive authority in distinctly delineated spheres of jurisdiction, creating a layer-cake view of federalism. Cooperative federalism, on the other hand, is a style of federalism where both levels of government coordinate their actions to solve national problems, leading to the blending of layers like a marble cake.
Categorical grants and block grants are two types of federal grants given by the national government to lower government levels to subsidize the cost of implementing policy programs. Categorical grants come with specific conditions and guidelines on how the money should be used, while block grants provide more flexibility for state and local authorities to decide how to use the funds.
