What was one outcome of the Spanish-American War?

The outcome of the Spanish-American War in 1898 significantly reshaped U.S. territorial holdings, leading to the correct choice. The war resulted in the United States gaining several key territories in both the Pacific and the Caribbean. Specifically, the U.S. acquired Puerto Rico and Guam from Spain, which expanded American control in the Caribbean. Additionally, the Treaty of Paris, which concluded the war, led to the U.S. purchasing the Philippines from Spain, further extending American influence in the Pacific region.

This acquisition of territory marked a pivotal point in U.S. imperialism as it demonstrated the nation's emerging role as a global power, impacting future foreign policy and military strategy. The outcome of the war set the stage for the U.S. to assert its dominance in international affairs during the 20th century.
