The correct answer to this open question is the following.
The short paragraph that explains the central idea of the article is the following.
Cesar Chavez was one of the most important leaders of the farmer labor rights movement in the South of the United States. As the text refers, in 1962 he dropped a decent job that gave him enough money to live to fund the National Farm Workers Association. Without the intention of becoming a prominent labor rights leader, Cesar Chavez liked to fight for what is right. His idea was to create a strong Union so farmers could demand what was right. Decent pay for their labor. To work a fair number of hours and under healthy conditions. However, the endeavor was not an easy one. As the text says, Chavez soon realized that the fight against labor injustice would require patience, endurance, and enthusiasm to fight discrimination, and poverty.
