The People's Party platform, also known as the Populist Party, included several proposals during the late 19th century. Let's go through each option provided in the question:
1. Government ownership of railroads: This proposal was included in the People's Party platform. The Populists advocated for government control of transportation, including railroads, to ensure fair pricing and regulation.
2. The free and unlimited coinage of silver at a 16 to 1 ratio: This proposal was included in the People's Party platform. The Populists supported the unlimited coinage of silver to expand the money supply and increase the amount of currency in circulation.
3. A graduated income tax: This proposal was included in the People's Party platform. The Populists pushed for a progressive income tax where higher earners would pay a larger percentage of their income in taxes.
4. Women's suffrage: This proposal was NOT included in the People's Party platform. While the Populists were focused on economic reforms and addressing issues related to farmers and laborers, they did not specifically advocate for women's suffrage in their platform.
