At first they weren't killing the Jews, they would experiment but not kill. but they "collected" so many that they had to get rid of many of them.
The Aborigines found themselves in a situation were they were systematically assimilated into a new culture without being able to do anything. The children where taken away from their parents, and they were raised by people that were of British descent or were educated in British based institutions. That led to the children learning only what their British parents and institutions were teaching them, thus not being able to preserve anything from the Aboriginal culture.
Also, there were forced marriages between the British settlers and the Aboriginal women with the purpose of ethnically wiping out the Aborigines in few generations. That was one of the worst methods that has been used for destroying indigenous people.
The first one is incorrect because both of those happened during the founding and growing of the U.S.
The second one is correct because the U.S. used different form of propaganda to scare people away from communism, which lead to the Red Scare. Also we successfully kept communism from spreading to many countries that were close to falling into that form of government with the method of containment.
The third one is incorrect because the <span>Good Neighbor Policy was toward the Latin Americas, not toward any communist state.
The fourth one is incorrect because we were not isolated in our foreign policy, which is why we entered the Cold War and won against communist Russia.
Hope this helps!
