Writing Homework Help

I’m working on a writing multi-part question and need an explanation to help me understand better.

1 How might the diversity of governmental units and their respective ranges of authority impinge on your ability to implement and/or evaluate a program?

2 What was the significance of cases like U.S. v Lopez and Reno v Condon for intergovernmental relations? In what ways do they illustrate the evolution of IGR and in what ways do they illustrate the limits to evolution?

3 In Printz v U.S. the Supreme Court held that the federal government could not require state government executive officials to regulate private persons according to federal standards. What does this mean and why is it significant?
