the spanish - american war helped the united states become a strong leader in the americas. increase control…

Brief Explanations:

The Spanish - American War (1898) was a conflict between the United States and Spain. After the war, the U.S. gained territories like Puerto Rico, Guam, and the Philippines. This war also enhanced the U.S.'s influence in the Americas. The Monroe Doctrine (1823) had the goal of preventing European colonialism in the Americas. But the Spanish - American War specifically helped the U.S. emerge as a more prominent power in the Americas. It was not mainly about increasing control of South American countries (as the focus was more on Caribbean and Pacific territories from Spain), nor was it about increasing trade with European countries (the war was more about territorial and influence gains in non - European areas related to Spain's colonies), and preventing foreign expansion into the Americas was more of a long - term principle (Monroe Doctrine) rather than the direct result emphasized here. The key outcome relevant to the options was the U.S. becoming a stronger leader in the Americas.

Answer:

The Spanish - American War helped the United States become a strong leader in the Americas.
