Explanation:

The question is about how the acquisition of Guam in 1898 benefited the US in the early 20th - century. Demonstrating naval superiority in the Caribbean Sea is not related to the acquisition of Guam. Proving to other nations that the US would enforce the Open - Door Policy is also not directly related to the acquisition of Guam. Securing US presence in the Pacific Ocean is relevant as Guam is a Pacific island and its acquisition strengthened US presence in the Pacific. Showing other nations the advantages of Dollar Diplomacy is not related to the acquisition of Guam.

Answer:

By securing US presence in the Pacific Ocean
