Answer:
The Judiciary Act of 1789 had several key provisions, and among the options you provided, it did the following:
- Established that each state would have at least one federal district court.
This Act also created federal circuit courts and specified the jurisdiction of the federal courts, further defining the federal judicial system in the United States. It did not formalize the Supreme Court as the highest court, as this was already established by the U.S. Constitution, and it did not determine what types of cases are heard in the federal court system, as this is primarily defined by federal law and the Constitution itself.
