Which is an effect of the Mexican-American War? 1.added Florida and Texas to the United States
2.added New Mexico and California to the United States
3.the US lost New York
4.the US took over Canada

I believe the answer would be 2.added New Mexico and California to the United States

Explanation:

The Treaty of Guadalupe-Hidalgo settled the war and gave the USA disputed texan territory, California and New Mexico

the big stick policy was to still look powerful, and be nice at the same time. the big stick policy was also to countries who were at war, find peace with eachother.

the dollar diplomacy was to expand american business and get it to latin america, for that would be good for the economy.
