Question

a result of the kansas-nebraska act of 1854 was
the implementation of the
fugitive slave act.
the elimination of popular
sovereignty.
the formation of the
republican party.
the enforcement of the
missouri compromise.

Explanation:

To solve this, we analyze each option:

• The Fugitive Slave Act was part of the Compromise of 1850, not a result of the Kansas - Nebraska Act.
• The Kansas - Nebraska Act actually used popular sovereignty (allowing settlers to decide on slavery), so it didn't eliminate it.
• The Missouri Compromise was repealed by the Kansas - Nebraska Act, not enforced.
• The Kansas - Nebraska Act led to the formation of the Republican Party as opponents of the act (including anti - slavery Whigs, Free - Soilers, etc.) came together.

Answer:

the formation of the Republican Party.
