1. D. Using military and leadership to take control of an area. Imperialism is the act of where a larger government will try to take control over smaller ones to essentially grow theirs, even if it leads to war.
2. D. North Atlantic Treaty Organization. Also called NATO, this joined the United States along with European countries, they all agreed that if one of them got attacked, the rest would join and help defend one another.
3. C. Peace Corps. The Peace Corps, which was established March 1, 1961, was made to fulfill world peace and help people around the world.
4. B. Intervention. This was called the Zimmerman Note, where Germans told Mexico, that if they attacked the United States, Germany would help them retake their lost territories. This obviously angered Americans. This essentially brought the United States into the Great War, or in this case, intervening.
