Question

mexican farm workers in the united states faced many hardships in the 1960s, including
broken treaties with the united states.
good pay and discrimination.
lack of protection for their lands.
being denied their full rights as us citizens.

Explanation:

Migrant farm workers in the U.S. in the 1960s were often low-wage laborers, facing systemic pay inequities and discrimination based on their immigrant status, race, or ethnicity. The other options do not apply: broken treaties relate to Indigenous groups, land protection was not their core issue, and most were not U.S. citizens to be denied citizen rights.

Answer:

poor pay and discrimination.
