Please can someone help me. Thank you. How did the United States govern its new-found territories?

The correct answer to this open question is the following.
The United States administered its newfound territories in the following way.
We are talking about the new territories that the United States gained after defeating Spain in the Spanish-American War of 1898. The new territories were Guam, the Philippines, and Puerto Rico. Guam became an incorporated territory for the United States in Micronesia. Puerto Rico became a protectorate of the United States. The Philippines had many conflicts and tried to rebel against the control of the US, and finally became independent. In the case of Cuba, it never was part of the US. It became independent from Spain but always had a heavy influenced by the US until Cuba's Revolution that was led by Fidel Castro.

The correct answer is: it shows that ancient humans hunted the now exinct creatures.
