The precedents that George Washington set during his presidency are:
b. he chose well-known leaders to run his executive departments and serve as his advisors
d. he chose not to run for a third term
Options a and c are not correct as specific precedents set by Washington. While he did help establish a judicial system, the specific structure of nine justices was later solidified by Congress. Additionally, there was no dedicated "tax and tariff cabinet position"; rather, matters of taxation typically fell under the Department of the Treasury, which Washington established but did not create a separate position for just tax and tariff issues.
