The three powers that are assigned exclusively to the Senate are:
-
Confirm Presidential appointments - The Senate has the authority to confirm or reject presidential appointments, including Cabinet members, federal judges, and ambassadors.
-
Try cases of the impeachment of federal officials - The Senate is responsible for conducting the trial for federal officials impeached by the House of Representatives.
-
Ratify treaties - The Senate must ratify treaties negotiated by the President before they become legally binding.
So, the correct selections are:
- Confirm Presidential appointments
- Try cases of the impeachment of federal officials
- Ratify treaties
