Read the excerpt from "Freedom Walkers” by Russell Freedman.

In October 1955, several months after Claudette [Colvin] was convicted, Mary Louise Smith, an eighteen-year-old black girl, was arrested when she refused to move to the back of the bus so a white woman could take her seat. "[The driver] asked me to move three times,” Smith recalled. "And I refused. I told him, ‘I am not going to move out of my seat. I am not going to move anywhere. I got the privilege to sit here like anybody else does.’”

Smith’s case did not create the furor that the Colvin case did, because Smith chose to plead guilty. She was fined five dollars. Once again, Nixon decided that Smith, like Colvin, wasn’t the right person to inspire a battle against bus segregation.

What key detail develops the idea that Smith "wasn’t the right person to inspire a battle against bus segregation”?

She was arrested “several months after Claudette [Colvin] was convicted.”
She was “an eighteen-year-old black girl.”
“Smith chose to plead guilty.”
“She was fined five dollars.”
