what was the result of the Mexican war?

a. The US acquired a small tract of land that is now part of at least seven states.
b. The US acquired a small tract of land that is now in New Mexico.
c. Texas became an independent nation.
d. The Louisiana territory was purchased by the United States from France.

a. The US acquired a small tract of land that is now part of at least seven states.

The correct answer is:

a. The US acquired a small tract of land that is now part of at least seven states.

The result of the Mexican-American War, which occurred from 1846 to 1848, was that the US acquired a significant amount of territory from Mexico. To find the specific answer to your question, let's break down the options:

a. The US acquired a small tract of land that is now part of at least seven states.
This statement is partially correct. However, it is an understatement, as the US acquired much more than just a small tract of land. So, this option is not the correct answer.

b. The US acquired a small tract of land that is now in New Mexico.
This statement is also partially correct. While the US did acquire land that is now part of New Mexico through the Treaty of Guadalupe Hidalgo, it is not the only territory that was gained. Therefore, this option is not the correct answer either.

c. Texas became an independent nation.
This statement is incorrect. Texas had already gained independence from Mexico during the Texas Revolution in 1836, a decade before the Mexican-American War. So, this is not the correct answer.

d. The Louisiana territory was purchased by the United States from France.
This statement is not relevant to the Mexican-American War, as the Louisiana Purchase occurred in 1803 and did not involve Mexico. Therefore, this is not the correct answer.

The correct answer is a. The US acquired a significant amount of land that is now part of at least seven states. Through the Treaty of Guadalupe Hidalgo, which ended the war, Mexico ceded much of its northern territory to the United States. This included what is now California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming, among other areas.
