The correct choice regarding the precedents established by President Washington and Congress when they organized the new government is:
Creating three levels of federal courts and defining their powers.
This was established with the Judiciary Act of 1789, which set up the federal court system. The other options mentioned did not become formal precedents during Washington's presidency or under the organization of the new government. For instance, the two-term limit on the presidency was adopted by custom and not formalized until the 22nd Amendment in 1951, while the power of the Supreme Court to declare laws unconstitutional (judicial review) was established later in the landmark case Marbury v. Madison in 1803.
