Answer 1

One advantage the federal system of government has over a confederal system is that it allows for a stronger central authority to maintain national unity and address issues that affect the entire country, while still granting states the power to govern locally. One advantage the federal system of government has over a unitary system is that it promotes greater political participation and representation by allowing individual states to enact and enforce laws that reflect their unique needs and values.
