A more thorough explanation:

Cooperative federalism is a system of government where the federal government and state governments work together to make decisions and carry out policies. In this system, both levels of government have their own powers and responsibilities, but they also share some responsibilities.

For example, the federal government might provide funding for a state program, but the state government would be responsible for implementing and managing the program. Another example is disaster response, where the federal government and state governments work together to provide aid and support to affected areas.

Cooperative federalism is important because it allows for a more efficient and effective government. By working together, the federal government and state governments can pool their resources and expertise to address complex issues and provide better services to citizens.
