Question

All of the following are results of the Mexican-American War except —

President Polk was hailed as a hero in declaring and decisively winning the Mexican-American War

the U.S. acquired territory that included California and Arizona

the U.S. gained control of Texas

Hispanics who lived in the newly acquired territories received full U.S. citizenship

Answer 1

"Hispanics who lived in the newly acquired territories received full U.S. citizenship" — this is NOT a result. Although the Treaty of Guadalupe Hidalgo nominally extended citizenship to Mexican residents who remained, in practice many lost land, political rights, and faced discrimination and legal disputes, so they did not receive full and equal citizenship.
