Final answer:
The U.S. Supreme Court exercises its original jurisdiction in cases involving states, ambassadors, and public ministers.
Step-by-step explanation:
The U.S. Supreme Court exercises its original jurisdiction in cases between two or more states, cases affecting ambassadors, other public ministers and consuls, and cases in which a state is a party.
For example, if two states are involved in a dispute over water rights, the U.S. Supreme Court can hear the case directly rather than waiting for it to go through lower courts. Additionally, cases involving foreign ambassadors or cases where a state is suing another state can also be heard by the Supreme Court under its original jurisdiction.
Therefore, the types of cases that can lead to the U.S. Supreme Court exercising its original jurisdiction are cases between two or more states, cases affecting ambassadors and other public ministers, and cases in which a state is a party.
