Answer:
both proposed to restrict the expansion of slavery into new territories.
Step-by-step explanation:
The Wilmot Proviso was a proposed amendment to a bill in Congress in 1846 that aimed to prohibit slavery in any new territory acquired from Mexico during the Mexican-American War. The Free-Soil movement emerged in response to the Wilmot Proviso and supported the idea that slavery should not be allowed to expand into new territories.
Therefore, both the Wilmot Proviso and the Free-Soil movement proposed to restrict the expansion of slavery into new territories.
