Explanation:

The Progressive Era was a period of rapid social and political reform in the United States during the early 1900s, that ushered in comprehensive labor laws, a ban on the sale of alcohol, and women’s suffrage. Progressive political leaders, such as President Theodore Roosevelt, also aimed to reduce political corruption and curtail monopolistic business practices, a complete reversal from the late 19th century’s prevalence of political and corporate exploitation. During the Progressive Era, Congress established federal laws regulating the meat-packing, railroad industries, strengthened anti-trust laws, and enacted constitutional amendments, such as the 16th Amendment that established the income tax and the 17th Amendment that allowed for the direct election of senators.
