Final answer:
The party with more than 50% of the legislators is the majority party, and the one with less than 50% is the minority party. The majority party enjoys significant legislative power and control, while the minority party provides crucial opposition and alternative policy perspectives.
Step-by-step explanation:
The party to which more than 50% of the elected legislators belong is known as the majority party; the party to which less than 50% of the legislators belong is known as the minority party.
In many political systems, the majority party holds significant power, including the ability to set legislative agendas, control committee memberships, and exert influence over the policymaking process. This is because the majority party controls more than half the seats in the legislative chamber, enabling it to pass legislation more easily and enact preferred policies into law. The minority party, while holding fewer seats, plays an essential role in presenting alternative viewpoints and challenging the majority party's propositions during legislative debates.
