The United States acquired which of the following territories as the result of the peace treaty ending the Spanish-American War?

The correct answer is that the United States acquired Puerto Rico, Guam, and the Philippines as a result of the peace treaty ending the Spanish-American War, specifically the Treaty of Paris signed in 1898. This treaty marked a significant shift in U.S. foreign policy and emerged following the conflict that began in 1898 over the issue of Cuban independence from Spain.

Through the Treaty of Paris, Spain relinquished its control over these territories, which had strategic importance for the United States. Puerto Rico and Guam were directly acquired, representing a foothold for the U.S. in the Caribbean and the Pacific. The Philippines was also ceded to the U.S. for a payment of $20 million, reflecting America's intent to expand its influence and presence in Asia.

The other territories mentioned in the other choices do not correctly align with the outcomes of the Spanish-American War. Hawaii was annexed by the U.S. prior to the war, making it irrelevant in the context of this particular treaty, while Cuba gained its independence rather than being acquired. Choosing the right combination of territories reflects a clear understanding of the historical events surrounding the Spanish-American War and the resulting changes in U.S. territorial claims.
