The precedents that George Washington set during his presidency among the options you provided are:
- He chose well-known leaders to run his executive departments and serve as his advisors.
- He chose to not run for a third term.
While Washington did play a significant role in the establishment of the judicial system, the specific structure of nine justices has evolved over time and cannot be directly attributed to him. Additionally, the establishment of a Tax and Tariff cabinet position is not a specific precedent set by Washington, though he did address taxation and tariffs during his presidency. Therefore, the other two options are the correct precedents.
