Answer: D
Step-by-step explanation:
During World War I, many minorities traveled abroad, where they were treated as equals to their white counterparts. This experience gave them a new perspective on the discrimination and inequality they faced back home in the United States. Many African American soldiers, for example, returned home with a heightened sense of pride and determination to fight for their rights and against the racism they had experienced. This shift in perspective was a major change for minorities after traveling abroad during World War I.
