Answer: America sought to impose itself as a world power.
Explanation:
The reason for joining the united states is the effort to impose itself as a world power after decades of isolation. In that direction, they acted to exploit the revolution in Cuba that the population sought to achieve because of Spanish dominance. So the cause was the Cuban Revolution, and the real reasons are the effort to make the country stand out on the international front as a vital force.
Many riots and internal problems weakened the Spanish. In such circumstances, America wanted territorial expansion. The end of the conflict brought Cuba independence, but Cuba was under US jurisdiction. The Philippines, Guam and Puerto Rico have become parts of the United States.
The Texas democratic party passed rules to ensure continued discrimination.
Isolated
Isolated means far away from everyone or everything else. The hermit who lives on a remote island is isolated from the rest of the world, with nothing but coconuts and fish to keep him company.
The word isolated comes from the Latin word insula, which means island. You don't have to be on a remote island to feel isolated, though. Even people who live in big cities can feel a sense of isolation if they don't have many friends and spend a lot of time alone. In addition to remote or set apart, isolated can mean a single event, or incident. The high school students assured their principal that the cafeteria food fight was an isolated incident, promising that it would never, ever happen again.
