The precedents that George Washington set during his presidency include:
- He chose well known leaders to run his executive departments and serve as his advisors.
- He chose to not run for a third term.
The other options listed are not accurate in the context of precedents set by Washington:
- The judicial system of nine justices was established through the Judiciary Act of 1789, which Washington signed, but it was not solely his precedent.
- There was no specific "Tax and Tariff cabinet position" established by Washington; instead, he had a Secretary of the Treasury who managed financial matters, including taxes and tariffs.
So, the correct selections are the second and fourth options.
