Question

Why was the United States willing to pay more per mile for the Gadsden Purchase than for the Mexican Cession?
A-The land may have been small, but it completed the state of Arizona.
B-The United States wanted to prevent clashes along the southern border.
C-The Gadsden Purchase gave the United States land to build a railroad.
D-The United States paid more money to make amends with Mexico.

Answer 1

Mexicans wanted money to "reimburse" what the Native Americans had taken from them during the war. The U.S also wanted land to build a railroad. To compromise, the U.S and Mexico both agreed to the Gadsden purchase.
