Answer:
B. They were often pushed into low-paying jobs with poor working conditions.
Explanation:
After the Treaty of Guadalupe Hidalgo in 1848, which ended the Mexican-American War, nearly 75,000 Mexicans living in the American Southwest received US citizenship. That didn't guarantee that they would have no problems, though. The main problem they faced was that the white settlers forced them out of their land and jobs, sometimes even by force. The government didn't pay attention to the fact they couldn't return to their own land, and whenever such matters reached court, judges and lawyers would have a Mexican American landowner spend every bit of money he had.
Besides that, Mexican Americans were forced to take the worst-paying jobs with the worst conditions, often working almost like salves, cattle herders, and cartmen, or undertaking dangerous mining tasks.
