Read the excerpt from "Lessons of Dr. Martin Luther King, Jr."During my first fast in 1968, Dr. King reminded me that our struggle was his struggle too. He sent me a telegram which said, "Our separate struggles are really one. A struggle for freedom, for dignity, and for humanity." . . .Dr. King challenged us to work for a greater humanity. I only hope that we are worthy of his challenge.Based on the details in this passage, which theme best represents the ideas presented in Chavez’s speech?
