In the Senate, a filibuster can be ended by invoking which parliamentary device?

• A. Cloture
• B. Rider
• C. Quorum
• D. Markup

Answer: (A)

Ending a filibuster in the Senate relies on invoking cloture, a parliamentary device that sets a time limit on debate and brings the chamber to a vote. A filibuster blocks a bill by prolonged debate, and cloture is the mechanism that stops the delay by requiring a supermajority to proceed. Once cloture is invoked, debate is constrained and a final vote can occur, typically with about 60 votes needed to adopt the motion in most situations. This rule exists to balance minority rights with the majority’s ability to move legislation.

Riders attach additional provisions to a bill but don’t end a filibuster. Quorum is the minimum number of members required to conduct business, and failing to meet it halts proceedings rather than directly ending a filibuster. Markup is the process of editing a bill in committee, not about concluding debate.
