Amajor result of the spanish-american war
(1898) was that the united states
(1) adopted a policy of isolationism
(2) assumed a more prominent role in world
affairs
(3) gave up control of territories outside the
western hemisphere
(4) increased foreign aid to european allies

The correct answer is 2) Assumed a more prominent role in the world.

The Spanish-American War resulted in America becoming more involved in annexing territories in the Western Hemisphere. For example, the Spanish-American War ended with the Treaty of Paris. This Treaty resulted in the US gaining Puerto Rico, Guam, and the Philippines. Shortly after this, the US would go on to annex Hawaii and continue their expansion. This era of expansion is known as the Age of American Imperialism.
