Question

4/21 choose three items that contributed to the civil war; lincoln abolishing slavery when he was elected kansas nebraska allowing for popular sovereignty dred scotts decision that slaves were property, not people uncle toms cabin exposing the truths behind union attacks on southern forts

Explanation:

To determine the three items contributing to the Civil War:

1. Kansas - Nebraska Act: Introduced popular sovereignty over slavery in new territories, escalating sectional tensions.
2. Dred Scott Decision: Ruled slaves were property, not citizens, and Congress couldn’t ban slavery in territories, worsening North - South divisions.
3. Uncle Tom’s Cabin: Exposed the harsh realities of slavery, galvanizing anti - slavery sentiment in the North and angering the South.

“Lincoln abolishing slavery when elected” is incorrect (he aimed to restrict its spread initially, and emancipation came during the war). “Union attacks on Southern forts” happened after the war started (Fort Sumter was a Confederate attack on a Union fort, or Union response came later), so it’s not a cause.

Answer:

Kansas Nebraska Act allowing for popular sovereignty, Dred Scott’s decision that slaves were property, not people, Uncle Tom’s Cabin exposing the truths behind slavery
