Final answer:
Jane Addams nominating Teddy Roosevelt in 1912 symbolized the Progressive Party's recognition of women's roles in politics and the enduring Progressive ideals like direct democracy and regulatory reforms.
Step-by-step explanation:
When Jane Addams placed Teddy Roosevelt's name in nomination for the presidency in 1912, it symbolized the new role of women within the Progressive Party, and the continued influence of Progressive ideals in American politics. The Progressive Party, also known as the Bull Moose Party, embodied a more activist approach to government, directly challenging the traditional two-party system. Roosevelt's campaign focused on themes of direct democracy, business regulation, and expanded federal power, indicating a strong public demand for progressive change regardless of the presidential election's outcome with Woodrow Wilson ultimately winning.
