Why did nixon believe that his idea might succeed in bringing about change?
(his idea on what to do after rosa parks was arrested.)

NAACP Chapter President E.D. Nixon believed that due to the nature of her arrest, Rosa Parks was the right person who could arouse the anger of the Black community to spur them into action. Someone they can  rally to as a symbol of the fight against segregation.  He began to meet with Martin Luther King, Jr.  to organize a boycott the city. This resulted in a victory against the bus segregation system and was upheld by the Supreme Court.

According to Mark Twain, "standards" are the lasting ideas people have, whereas "fashions" are just temporary trends or beliefs that change across the years.

As an example of "standards," Twain cites Shakespeare because, for centuries, his pieces have been adopted and recreated by people worldwide.

As an example of "fashions," Twain considers the different styles of music, writing, and technology being the latter the most changing with the passing of time.
