The post World War scenario was highlighted by the fall of some colonial powers and the rise/peaking of some others. A redistribution of colonies and territories took place following the Treaty of Versailles. Germany was the biggest loser, while Britain and France gained the most new territories
African Americans in the South often help Union forces by serving as spies and scouts. African Americans did all they could to help the Union army. This was especially true after the Emancipation Proclamation, as Lincoln attempted to free slaves from the control of Confederate states. This was one of the many reasons why African Americans in the South helped Union forces. These citizens often acted ignorant or didn't appear to be paying attention when Southerners discussed their next military moves. African Americans would then relay this information to the Union commanders, giving them a strategic advantage.
Due to the fact that the first and third don't make sense, I think the answer should be the second.
Hope this Helps! :)
