Well that's easy. Auschwitz was a death camp, and Manzanar was an internment camp. The difference is that Auschwitz was used by the National Socialist German Workers Party (Nazis) as a eugenics machine. Eugenics is the practice of removing certain genes from the gene pool, through sterilization, or murder to create a perfect human race (Aryan). While Manzanar was used to hold 11,000 Japanese Americans during world war two who were seen as public enemies. Both Concentration camps and Internment camps were racially motivated, and both were used for public enemies. Concentration camps were far more violent, and were also politically motivated, used to remove party enemies.
The correct answer is maintain international peace and security.
After world war 2 the countries of the world realized that they had to prevent another such war from ever happening again. They tried to do it even after world war 1 with the league of nations but that project failed as it didn't have the support of various armies from the world such as the US army. The United Nations however got even Americans on board and still exists today.
Industrial expansion and population growth radically changed the face of the nation's cities. Noise, traffic jams, slums, air pollution, and sanitation and health problems became commonplace. Mass transit, in the form of trolleys, cable cars, and subways, was built, and skyscrapers began to dominate city skylines.
