Nebraska, Kansas, Utah, New Mexico were territories open to slavery at this time
The correct answer to this open question is the following.
In each of the mentioned events, Dr. Martin Luther King, Jr. demonstrated his commitment to nonviolent demonstrations despite the local police's different aggressions.
The Montgomery bus boycott started on December 5, 1955, and ended on December 20, 1956. The March on Washington for Jobs and Freedom Alabama protests occurred on August 28, 1963, and approximately 250,000 participated in this historic demonstration.
Dr. King, Rosa Parks, and all the civil rights leaders who participated in both demonstrations resisted the police and other people's aggressions and maintained their commitment to never act violently. Indeed, it was the "trademark" of Dr. King's style.
I heard they could and couldn't. But to be on the safe side, I would pick false.
True! Hope this helped :)
