Answer:
The statement is false. By 1880, the United States did not have refueling stations for naval ships in the Philippines and Hawaii.
Explanation:
During the 1880s, Hawaii and the Philippines were not part of the American territory. Both territories were acquired in 1898, Hawaii through an annexation, and the Philippines as a result of the Spanish-American War. Therefore, at that time the United States could not have naval stations in those territories, as they had no sovereignty over them.
