Question

the spanish-american war helped the united states
become a strong leader in the americas.
increase control of south american countries.
increase trade with countries in europe.
prevent foreign expansion into the americas.

Explanation:

The Spanish-American War (1898) resulted in the U.S. acquiring territories like Puerto Rico, Guam, and the Philippines, and asserting dominance in the Caribbean. This established it as a major power and regional leader in the Americas. The other options are incorrect: the U.S. did not gain significant control over South American countries, the war did not focus on increasing European trade, and the Monroe Doctrine (not this war) was centered on preventing foreign expansion in the Americas.

Answer:

become a strong leader in the Americas.
