Step-by-step explanation:
Most delegates to the Philadelphia Convention agreed on the need to increase the power of the central government and decrease the powers of the state governments. The correct answer is B - increase, decrease.
The Constitutional Convention recognized the need for a stronger national framework to address the challenges facing the independent states under the Articles of Confederation. As a result, the U.S. Constitution significantly expanded the powers of the central government while also establishing a federal system that recognized the role of the states, thereby limiting their individual authority.
