Explanation:

In modern legislative processes, committees play a crucial role. They review, research, and revise proposed legislation. Leadership actions can influence but are not the key means. The budget process is a specific part of legislation, not the overarching key means. A filibuster is a delaying tactic, not an advancing one.
