one effect of the immigration act of 1965 on latin americans was that it\ndiscouraged illegal immigration…

Brief Explanations:

The Immigration Act of 1965 (also known as the Hart - Celler Act) ended the national - origins quota system that had favored European immigration. It established a new system that prioritized family reunification and skilled labor. For Latin Americans, this act made it easier for them to enter the United States because the previous quota system had severely restricted immigration from non - European countries, including many in Latin America. The option "discouraged illegal immigration from Latin America" is incorrect as the act's main focus was on legal immigration pathways and it didn't directly target illegal immigration in a way that would discourage it. "Encouraged many unskilled workers to immigrate" is wrong because the act emphasized family reunification and skilled labor, not unskilled workers. "Limited the number of unskilled workers from Latin America" is also incorrect as the act opened up more legal immigration opportunities rather than limiting unskilled workers (and its focus was not on limiting unskilled workers from Latin America specifically).

Answer:

B. made it easier for them to enter the United States.
