The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The United States should go to war because its political and economic interests in the Island of Cuba were threatened by teh Spaniards.
At the end of the 1800s, the United States had developed interesting trade relations and cooperation with Cuba. However, the presence of the Spaniards represented a major risk to US interests in the region and that is why they supported the independence of Cuba and had to fight in the Spanish-American War of 1898.
In the end, the United States won the war and became the most powerful nation in the world, having surpassed Great Britain. With the victory, the United States gained control of three countries that had been controlled by the Spanish government: Puerto Rico, Guam, and the Phillippines.
