Read the excerpt from Dr. Martin Luther King’s “Letter from Birmingham Jail.”

I have earnestly opposed violent tension, but there is a type of constructive, nonviolent tension which is necessary for growth.

How does King support this claim in the rest of his letter?
by providing examples of recent nonviolent sit-ins
by quoting Socrates and establishing historical precedent
by chronicling the history of violent tension throughout the South
by presenting a visual image of a world in which equality reigns
