Final answer:
Congress's first major task after Washington's inauguration was to draft a Bill of Rights to protect individual freedoms, fulfilling Anti-Federalist expectations and supporting the ratification of the Constitution.
Step-by-step explanation:
After George Washington's inauguration as President in 1789, Congress's first major task was to fulfill Anti-Federalist expectations by drafting a Bill of Rights to protect individual liberties from a powerful government. This was in response to fears that the national government might intrude on civil liberties. These amendments were essential for obtaining the necessary support from Anti-Federalists to ratify the Constitution and were reflective of a compromise to balance the need for a strong central government with the protection of individual rights.
