- It gave the United States territory known as the Mexican Cession: This is true. The Mexican-American War resulted in the Treaty of Guadalupe Hidalgo, where Mexico ceded a significant amount of territory to the United States, known as the Mexican Cession.
- It enabled the United States to annex Texas: This is also true. The Texas Revolution, which preceded the Mexican-American War, resulted in the independence of Texas from Mexico. The Mexican-American War allowed the United States to officially annex Texas and add it as a state.
- It gained the respect of European nations for America’s military power: This statement is not directly related to the Mexican-American War. While the United States did gain some recognition for its military capabilities during the conflict, it was mainly seen as a regional conflict between Mexico and the United States.
- It increased unity among Americans by giving them a common enemy: This statement is partially true. The Mexican-American War did rally some Americans around a common cause and enemy, but it also generated significant controversy and opposition within the United States, particularly regarding the issue of slavery's expansion into the newly acquired territories.
