HEL There was a tension on North side of USA during Civil war because of slavery because some people on north didn't really like Black people but some people were ok with it. please give me some events that shows tension of this problem

Slavery played the central role during the American Civil War. The primary catalyst forsecession was slavery, especially Southern political leaders' resistance to attempts by Northern antislavery political forces to block the expansion of slavery into the western territories.

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

b. a system of government that provided a model for the united states.
