Answer:
1) The novel highlighted the cruelty of slavery.
Step-by-step explanation:
Before this novel, slavery was pretty much an ordinary thing in America, something that not many people questioned. However, after Harriet Beecher Stowe wrote it, depicting how cruel and inhumane the concept of slavery really was, it created turmoils in America, especially between the North and the South.
The North wanted to abolish slavery because of the way poor slaves were treated (especially highlighted in the novel), whereas on the other hand, the South profited too much from slaves to let them go that easily. This was one of the major causes of the Civil War.
