Answer:
The correct answer choices to fill in the blanks here, would be: President; Senate. Thus, the completed sentence would be: "President appoints new Cabinet members; Senate confirms them."
Explanation:
The reason for this being the correct answer is that, in fact, in American law, especially when it comes to certain appointments done by the President, these have to be confirmed by the U.S Senate. This is established under the Appointments Clause of the U.S Constitution, where it is stated that for certain appointments, known as Presidential Appointment needing Senate confirmation, or PAS, the President needs not just the consent, but also the advice from the Senate, in order for the appointment to be ratified.
