    Wilmot's purpose in proposing this rider was best described as which of the following?

    • A

      Extending the Missouri Compromise line to the Pacific

      Abolishing slavery throughout the existing United States

    • C

    • D

      Annexing Texas as a free state

    Why

    The Proviso targeted only territory taken from Mexico, not existing states. It rejected, rather than extended, the 36°30' line; Texas was already annexed in 1845.

    • C

      An American defeat that forced the U.S. to cede Louisiana, Texas, and the Oregon Country back to Mexico

    • D

      U.S. acquisition of vast territory (California, Nevada, Utah, Arizona, etc.) via the Treaty of Guadalupe Hidalgo
