Most white Southerners reacted to defeat and emancipation with dismay. Many families had suffered the loss of loved ones and the destruction of property. Some thought of leaving the South altogether, or retreated into nostalgia for the Old South and the Lost Cause of the Confederacy and they were not very happy.
The freedom of jobs? im terribly sorry :(
A - Because they are a direct link to the events in history
Primary sources are sources that came from that time of history from the same location, time period, and era. For instance, journals from World War II from a French Military leader. These are direct links to that time in history and are the most accurate sources that are presented.
B is incorrect as even without these sources there are other methods to know about history such as secondary sources.
C is incorrect as primary sources are not the only way - again, secondary sources are a thing.
D is incorrect as secondary sources are reliable and can be trusted, but they just aren't as important and well, direct as primary sources.
Hope this helps!
C. especially the North since they had the most resources, and more people they thought the South would easily lose.
B: settle the US from the Atlantic to the Pacific Ocean
