Hi! :)
Answer: A. They destroyed the South’s morale and captured its capital, forcing the South to surrender.
There were no specific routes, however, Sherman and Grant had targets and if they would be able to bring down their targets, it would be easier for them to take over.
They had destroyed many cities in the South so that they won’t be able to wage war because of the damages they had done in those cities.
B - Some communities closed their schools rather than to integrate.
While some in the the south did not want to integrate their schools, some communities refused (but not most) and they figured out plans to delay integration, transfer students to different schools and close others.
B: settle the US from the Atlantic to the Pacific Ocean
