Hello!
Hitler's goal was to establish a New Order based on the absolute hegemony of Nazi Germany on the European continent. Its foreign and domestic policy had the objective of seizing Lebensraum ('vital space') for the Germanic peoples. It promoted the rearmament of Germany, for which Hitler pressed Austria for unification with Germany and this was followed by the intensification of the Sudeten crisis, in the German-speaking area of Czechoslovakia known as Sudetenland; This led to the Munich Agreement of September 1938, which authorized the annexation and immediate military occupation of these districts by Germany. Under these plans it could be said that the Nazi party has acted by attacking and occupying other territories. Hitler believed that Nazi Germany should demonstrate its superiority, which is why it had to fight to establish its hegemonic power in Europe.
I hope this helps!

Senator McCarthy scared the people so much that they almost started accusing each other of being communist supporters. He claimed that anyone could be a communist spy and families even broke apart because some of them who weren't even communists got accused of being communists. Also people would spy on their neighbors and similar things to see whether they were sympathizers of communism.
The man described in the question is Crispus Attucks.
Crispus Attucks was among a huge group of American colonists who were protesting against the passage of the Townshend Acts. These acts put taxes on several important resources such as lead and paper. The colonists protesting this act were face to face with British soldiers who were trying to bring order to the city. This scene turned violent at one point and resulted in the shooting/killing of Crispus Attucks, making him the first death of the American Revolution.
