Final answer:
During the Theodore Roosevelt, Taft, and Wilson administrations, the US witnessed significant political, economic, and social changes through the rise of progressivism, passage of important legislation, and introduction of progressive reforms.
Step-by-step explanation:
- Political Change: One important political change was the rise of progressivism. Roosevelt, Taft, and Wilson all embraced progressive ideals, which focused on curbing the power of big business, promoting social reforms, and increasing government intervention in the economy.
- Economic Change: The US experienced economic changes, such as the passage of important legislation like the Clayton Antitrust Act and the Federal Reserve Act. These laws aimed to regulate monopolistic practices and stabilize the banking system, respectively.
- Social Change: Social change was evident during this era with the introduction of progressive reforms. For example, the 19th Amendment was ratified, granting women the right to vote. Additionally, the Pure Food and Drug Act was passed, leading to greater consumer protection.
These changes were significant because they marked a departure from the laissez-faire policies of the Gilded Age and ushered in an era of increased government involvement and reforms to address social and economic inequality.
