It is a positive and unifying day for Americans.
Explanation:
It makes sense because if you actually read the questions you can see which one is not negative. :/
The Black Codes were put in place in south Carolina (as well as other places in the southern states) as a way to make whites continue to feel superior and suppressing the rights of African Americans, while technically not breaking the law, as they were not enslaving the Africans.

The Celts were not an unified state but rather a group of numerous tribes that often didn't even speak the same language. They were found all around Europe and were mostly Warriors who build their societies around kinship. They were good farmers and mostly were common people. They didn't have a strong unified state because they lived day in day out, women would give birth to children and men would work on the land and occasionally fight against invaders. There was no spirit of a great Celtic nation.
The 1930s were a difficult time for most Americans. Faced with colossal economic hardships—unprecedented in American history—many Americans turned inward to focus on the worsening situation at home. The United States became increasingly insensitive to the obliteration of fellow democracies at the hands of brutal fascist leaders like Hitler and Mussolini. The U.S. was determined to stay out of war at all costs—even if its allies were in trouble; Americans believed that they were immune from Europe’s problems as long as they refused to get involved. However, as the “free” countries fell, one by one, to the Nazi war machine, Americans began to realize the folly of their foolish optimism and clamored for increasing involvement in foreign affairs. American foreign policy changed in the years 1930-1941 as Americans realized that fascism would likely conquer all of Europe unless Americans acted quickly. Ultimately, it was fear of the fascist threat to American democracy that triggered the end of American isolationism and inaugurated the era of American interventionism.
