What event? The pandemic or from the past?
I'd say the correct answer is A. Uncle Tom's Cabin was most popular in the North.
B is definitely not correct because the book is about anti-slavery, and there were many slave owners in the South and they hated the book with a burning passion; thus C is also incorrect because the South almost banned the book; D is incorrect as the book was hugely popular in the North, having become an instant bestseller (took the second place after the Bible).
Peaceful protest, Complaining to the US Supreme Court, and showing how they were just normal people by helping the country advance in technology, (Katherine Goble, etc)
They had to deal with segregation,
Discrimination in the workplace, limited jobs due to rascism,
and terrible education.
B.C.E. comes before C.E.
Hope this helps!
