what was the last state added to the united states?
○ hawaii
○ puerto rico
○ oklahoma
○ alaska

Explanation:

To determine the last state added to the US, we recall: Alaska was added in 1959 (January), and Hawaii was added later in 1959 (August). Puerto Rico is a territory, not a state. Oklahoma became a state in 1907. So Hawaii is the last state added.

Answer:

A. Hawaii
