Final answer:

Step-by-step explanation:
Role of Minor Parties in Political Systems
Minor parties play a significant role in political systems, serving as critics of the parties in power. By voicing objections and proposing alternative policies, they function as a check on the ruling party's power. Although third parties, or minor parties, often do not win elections, they are pivotal in bringing attention to specific issues, influencing the major parties' platforms, and acting as a safety valve for voter discontent with the traditional two-party system. A remarkable example of their impact is the 'spoiler' role, where their presence in an election can change the outcome by drawing votes from one of the major parties. Additionally, third parties contribute to democracy by encouraging candidate recruitment, enhancing the diversity of choices available to voters, and keeping the electoral process dynamic and responsive to public interests.
