Answer:
The earth "can" is the answer
During the Nazi regime, there were several different factors that allowed for the persecution and extermination of minority groups. This includes:
Political factors
The rise in power of Adolph Hitler was the most significant political factor that allowed for the persecution of Jews and other minority groups. His feelings about these groups were expressed in the book he wrote (Mein Kempf) and his speeches to the German people. Since he had absolute control over the government and military, he could have individuals he didn't like killed at any time.
Social factors
A series of written and spoken propaganda convinced German citizens that the root of their economic problems were the Jewish people. These posters and speeches were spread so often that people started to believe them. This allowed for the extermination and persecution of individuals in Germany, as average citizens saw nothing wrong with getting rid of these people who were causing the problems.
Traded Goods. Goods which were traded within Greece between different city-states included cereals, wine, olives, figs, pulses, eels, cheese, honey, meat (especially from sheep and goats), tools (e.g.: knives), perfumes, and fine pottery, especially Attic and Corinthian wares.
Fortunately, many Navajos still speak their language. During World War II, about 420 Navajos served as Code Talkers—the most from any Native group. The Navajo homeland: Four sacred mountains covering 27,000 square miles of the four corners area of Utah, New Mexico, and Arizona define the Navajo homeland, “Dinétah.”
