What kind of effect could an all-American AEF have on its enemies?

a) the AEF could serve as a propaganda tool for the Soviets

b) the AEF could bolster Allied morale and intimidate the Central Powers

c) the AEF could serve as a distraction for the Central Powers while France took Normandy

d) the AEF could train the other Allied soldiers how to fight

An all-American Expeditionary Force which was organized in WWI was perhaps considered as less challenging to fight than say a British force at least when they initially went into battle until they gained experience as they did not appear to have as much fighting experience as say the British or French who I believe entered the war earlier

so the answer would be C.
