Question

which constitutional principle was being practiced at the event represented by this ticket? a. popular sovereignty b. separation of powers c. federalism d. checks and balances

Explanation:

The ticket is for the 1868 U.S. Senate impeachment of a president. Impeachment is a process where the legislative branch (Congress) holds the executive branch (president) accountable, which is a core example of the checks and balances principle—each branch of government can limit the power of the others. Popular sovereignty refers to rule by the people, separation of powers is the division of government roles, and federalism is the split of power between national and state governments, none of which match this event.

Answer:

D. checks and balances
