Question

(answer this in 2 simple sentences please)

Answer 1

The Articles of Confederation established a loose confederation of states with a weak central government, while the Constitution created a stronger federal government with distinct executive, legislative, and judicial branches. Additionally, the Articles required unanimous consent for amendments, whereas the Constitution allows for amendments with a two-thirds majority in Congress and ratification by three-fourths of the states.
