SAT Subject US History Practice Question 683: Answer and Explanation
To which sections would the Wilmot Proviso have applied in the map above?
A. L and M
B. M and N
C. L and N
D. O and N
E. P and O
Correct Answer: C
L and N are correct because they describe the Mexican Cession. The Wilmot Proviso (1846) stated that "there shall be no slavery or involuntary servitude in any territory from Mexico." The so-called Mexican Cession was won in the Mexican War; it included California and the whole Southwest and Mountain West, excluding the Oregon Territory. The United States paid Mexico $15 as part of the Treaty of Guadalupe Hidalgo (1848). The other choices include territory from the Louisiana Purchase (O), the Oregon Territory (M), or the Eastern states (P); none of these were part of the Mexican Cession.
