Write a paragraph describing what the Progressive Era (America) was? And how does it relate to the book The Jungle?

The Progressive Era, spanning from the 1890s to the 1920s, was a period in American history characterized by a surge of social activism and political reform aimed at addressing the problems caused by industrialization, urbanization, and corruption in government. Reformers sought to improve working conditions, expand suffrage, curb corporate power, and promote social justice. Upton Sinclair's novel "The Jungle," published in 1906, plays a significant role in this era by exposing the harsh realities of immigrant life in the meatpacking industry and the unsanitary conditions of food production in Chicago. The vivid depiction of exploitation and health hazards in "The Jungle" galvanized public opinion, leading to widespread calls for reforms in food safety regulations and labor laws, ultimately contributing to the establishment of the Pure Food and Drug Act and the Meat Inspection Act in 1906. Thus, the themes of social advocacy and reform in The Jungle exemplify the broader goals of the Progressive Era.
