Answer:
Work together to fight against social injustices
Explanation:
Cesar Chavez was a prominent union leader and labor organizer who fought for fair wages and humane working conditions for farmworkers in the US. He founded the National Farm Workers Association, which later became a part of the United Farm Workers, a labor union for farmworkers.
In his speech, he quotes Dr. Martin Luther King Jr., the key figure of the civil rights movement. They were both fighting for human rights, just tackling different issues. In the given passage, Chavez invites people to work together to fight against social injustices. Only if all of us fight together, something will change.
