Final answer:
The plurality system in the United States does not encourage the formation of minor parties.
Step-by-step explanation:
The statement that the plurality system in the United States encourages the formation of minor parties is False.
The two-party system in the United States, dominated by the Republicans and the Democrats, is primarily a result of electoral rules like plurality voting and the winner-take-all system.
Third parties in the United States often struggle to gain widespread support and have historically been spoilers rather than major players in the political landscape.
