Which of the folllow was a direct economic effect of the Spanish American wat in the United States
Crank

Answer:

The answer is A. The US acquired new overseas territories, leading to increased trade.

Explanation:

Before the SPAM War started, Cuba was attempting to launch a revolution from the Spanish to gain their independence. America saw this and became allies with the chain of islands under Spanish control. However, the US did not want to initiate warfare unless acts of war were put against them, per the "Big Stick Policy" by Teddy Roosevelt. The war was finally initiated when Yellow Journalism, when newspapers exaggerated stories, caused Americans to jump to conclusion that the SS Maine, in Havana Cuba,  was sunk by the Spanish. (It was later discovered that it was an engine explosion on behalf of human error). Anyway, the Cubans got their chance at independence when America decided to join them in battle. After the war was won, Cubans gained  their independence and the US got the rest of the islands (The Phillippines, Guatemala, etc.). This allowed American ships to have naval bases, increase manufacturing and trade, and allow for easier shipping for materials that could be traded in Western continents.
