Answer:
Star of Jude patches.
Explanation:
The 'Star of Jude' patches were small, yellow patches of fabric with a star of David as well as the word "Jude" (Jew in german) that Jewish people had to sew into their clothes in order for them to be identified by the public. This allowed for public shaming and discrimination as Jewish people were branded by the small patch. It was a law heavily enforced, even wedding dresses and formal clothes not permitted from it.
The U.S. had to make the American people understand that war was the right answer. They had to convince businesses that they would succeed and not fail during the war. The war itself, still faced opposition, but for the most part Americans supported our military in their efforts. The entry into the war, was one that was not taken lightly.
I think the answer will be D?
