Compare prehistory with history in terms of span of time

The main difference between history and prehistory is the existence of records; history is the recorded events of the past whereas Prehistory is the time before writing was introduced. Therefore, it is clear that prehistory, as the name suggests, is the time period before history.

Have a nice day ;)

hello!

according to the passage the most suitable options are two. the first one is "by leading the aef to victory in several key battles" like the battle of saint- mihiel and the battle of cantigny mentioned in the passage you copied here. the second one is "by the aef and allied forces defeat germany" since the passage says that his army destroy the german resistance in the meuse- argonne offensive. and also, "by insisting that the aef operate as an independent force".

hope this
