Final answer:
Under the Articles of Confederation, Congress had no power to make states enforce laws which led to a lack of unity and cohesion among the states.
Step-by-step explanation:
Under the Articles of Confederation, Congress had no power to make states enforce laws. This was a problem because it meant that the central government was unable to effectively govern the country. Without the power to enforce laws, states could choose to ignore or disobey them, leading to a lack of unity and cohesion among the states. This weakened the overall strength of the nation and hindered its ability to function as a unified entity.
