Final answer:
The political cartoon in question comes from the Progressive Era, which spanned from the late 19th to early 20th centuries, known for advocacy of social justice and political reform.
Step-by-step explanation:
The correct answer to which historical period the political cartoon comes from is A. The Progressive Era. This era is defined as the period from the 1890s to the 1920s in American history and is characterized by a widespread social activism and political reform across the United States. The era primarily addressed issues of social justice and the need for reforms due to rapid industrialization and urbanization. It focused on eliminating problems caused by industrialization, urbanization, immigration, and political corruption.
Political cartoons from this time often commented on issues like temperance, women's suffrage, child labor, and public health, depicting reformers' efforts to change society. The Progressive movement sought regulation of monopolies (trust-busting) and corporations through antitrust laws, as well as improvement in working conditions.
Muckrakers, a term used for progressive journalists, played a significant role during this period by exposing social ills and corporate malfeasance through their writings.
