Final answer:
The Granger Movement focused on regulating railroad rates and grain elevator prices to protect farmers, while the Populist Party continued to advocate for farmers and working-class people through various reforms.
Step-by-step explanation:
The Granger Movement/laws and the Populist Party were connected in their shared goal of advocating for the rights and interests of farmers. The Granger Movement, which emerged in the late 19th century, sought to regulate railroad rates and grain elevator prices in order to protect farmers from monopolistic practices. The movement resulted in the passage of Granger Laws in some states, but these laws were later ruled unconstitutional by the U.S. Supreme Court. The Populist Party, formed in the 1890s, continued the advocacy for farmers and working-class people and called for reforms such as a graduated income tax, direct election of U.S. Senators, and unlimited coinage of silver. While the Granger Movement declined, the ideas and goals it promoted influenced the formation of the Populist Party.
