Mexican immigrants was the most minority group affected by massive migration of Midwestern farmer to the Southwest. The first option is correct.
Despite its lengthy presence in the United States, the Mexican American population remains predominantly in the Southwest. The 1990 decennial census revealed that approximately 83% of Mexican people are located in one of five Southwestern states (Arizona, California, Colorado,New Mexico, Texas), a ratio of Mexican immigrants that was almost identical to that of the earlier decade.
Midwestern farmers traveling to Southwest America would be entering into Mexico (before the Mexican-American War), which included present-day Texas stretching to present-day California.
The resulting outcry across the United States led to a number of antiwar demonstrations—it was at one of these demonstrations that the National Guard shot four protesters at Kent State.
