Final answer:
The question is about American imperialism and progressivism, focusing on the concept of American exceptionalism, the painting 'American Progress' as an illustration of Manifest Destiny, and the expansion pursued by progressive reformers and missionaries.
Step-by-step explanation:
The student's question pertains to American imperialism and progressivism, indicating a historical context. Specifically, it involves an exercise matching descriptions to locations on a map, which illustrates the extent of American imperial ambitions and the progressive era's domestic reforms. One important aspect of American imperialism was its roots in the concept of American exceptionalism, the belief that the U.S. had a unique mission to spread freedom and democracy.
Moreover, the use of John Gast's painting 'American Progress' connects to the idea of Manifest Destiny, which perceived the expansion of the U.S. across North America as a divine right and inevitable process. This concept was also intertwined with technological advancement, cultural development, and economic growth.
Lastly, the missionary efforts post-Civil War exemplify how imperialism was not solely pursued by businesses but also by religious and progressive reformers, who believed in spreading American democratic and Christian principles internationally.
