Explanation
The Jones Act of 1917 (Jones-Shafroth Act) expanded the rights granted by the Foraker Act to Puerto Ricans. Most importantly, it granted U.S. citizenship to all Puerto Ricans. It also created a more democratic legislative system with an elected senate. The Teller Amendment concerned Cuba, Seward's Folly was Alaska, and Open Door Policy was about China.
