7. What can the reader conclude about Martin Luther King Jr. and his efforts to stop segregation in the United States?

To many millions of American Negroes, the Rev. Dr. Martin Luther King Jr. was the prophet of their crusade for racial equality. He was their voice of anguish, their eloquence in humiliation, their battle cry for human dignity. He forged for them the weapons of nonviolence that withstood and blunted the ferocity of segregation.

And to many millions of American whites, he was one of a group of Negroes who preserved the bridge of communication between races when racial warfare threatened the United States in the nineteen-sixties, as Negroes sought the full emancipation pledged to them a century before by Abraham Lincoln.

To the world Dr. King had the stature that accrued to a winner of the Nobel Peace Prize, a man with access to the White House and the Vatican; a veritable hero in the African states that were just emerging from colonialism.

in ray bradbury's short story "a sound of thunder", mr. eckels's fearfulness leads to drastic consequences for the rest of the world.

in the story, mr. eckels, who is a hunter, hires a time travel company to travel to the age of dinosaurs. although he is excited for the hunting expedition at the beginning, when they reach there and mr. eckels sees the tyrannosaurus, he feels frightened. as he is afraid of the tyrannosaurus, he steps off the path although he has been warned not to do it. by stepping off the path, the entire course of the future is affected: mr. eckart alters the future by stepping on a butterfly, which causes a new man to be elected president in the future. in that way, it is mr. eckart's fearfulness what triggers 'the butterfly effect' and what leads to drastic consequences for the rest of the world.
