How does Eisenhower use specific word choice to characterize the Allies and their enemies in this call to arms?

He referred to the Allies as brothers-in-arm and the enemy as German war machine

Explanation: Dwight Eisenhower was the supreme commander of Allied forces in Western Europe during World War II. He led the massive invasion of Nazi-occupied Europe that began on D-Day (June 6, 1944). Just before the invasion, he wrote a call-to-arms note to rally the troops to victory.

He started by referring to the Allied forces as "Soldiers, Sailors and Airmen of the Allied Expeditionary Force", then "brave Allies and brothers-in-arms on other Fronts" as well as "free men of the world marching together in victory". On the other hand, he referred to the enemy as "German war machine" as well as "Nazi tyrants oppressing the people of Europe"

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.  

the correct option is “cultural causes” since art and literature are related to the culture of a place. culture is determined by literature, art, music.

the correct option is “pop culture” since it reflects the likes and ideas of common people whereas the rest of the options do not focus on common people.  

the correct option is “multiple causation” since it refers to the idea that events are caused by multiple reasons, not just a single one.
