Read this excerpt from We’ve Got a Job. No one would have blamed Mr. and Mrs. Hendricks if they had decided to keep quiet about civil rights following the bombing of their friend's home. But Audrey's parents weren't intimidated. The very next day, her father and about fifteen other blacks sat down in the front section of a bus, where only whites were permitted. When the driver demanded they move to the back, Audrey's father politely refused, saying "We [are] comfortable where we are sitting." As a result, Mr. Hendricks was arrested and spent six nights in jail. When he was released, he volunteered to guard the Shuttlesworths’ home.

Why do Mr. Hendricks and others sit in a section of the bus where they are not permitted?

to figure out who is responsible for the previous night’s violence
to show they will keep fighting even though their friend’s home was destroyed
to rally other people in the area to join their fight against segregation laws
to experience the comfort and convenience of the front of the bus
