The United Nations was established so that it could resolve conflicts between nations by imposing sanctions
The correct answer is "B"
The Treaty of Guadalupe Hidalgo ended the Mexican-American War, but there were issues that needed to be resolved for both sides, such as the border limits of the La Mesilla Valley, protection for Mexico from attacks by Indian tribes and the right of transit through the Isthmus of Tehuantepec.
La Venta de La Mesilla (known as Gadsden Purchase in the United States) is a region of 76 845 km² of present-day southern Arizona and southwestern New Mexico that was purchased from Mexico by the United States in a treaty signed by US President Franklin Pierce who signed it on June 24, 1853 and the Mexican ruler Antonio Lopez de Santa Anna who signed it on December 30, 1853 and ratified by the United States Senate on April 25, 1854. The purchase included land south of the Gila River and west of the Rio Grande and was made for the purpose of building a transcontinental railroad along the southern route of the United States. It also solved the pending border problems after the Treaty of Guadalupe-Hidalgo that ended the Mexican-American War.
