Explanation:

The Monroe Doctrine was significant as it declared that the Americas were no - longer open to European colonization and intervention, establishing the U.S. as a regional power in the Western Hemisphere. Marshall court decisions, such as McCulloch v. Maryland, strengthened the national government by asserting its power over states in areas like taxation and the creation of a national bank, thus expanding federal authority.

Answer:

The significance of the Monroe Doctrine was to assert U.S. influence in the Americas and limit European intervention. Marshall court decisions increased national government power through landmark cases that expanded federal authority over states.
