I’m my story, which correctly describes a cause-and-effect relationship in this excerpt?

Cause: People had to walk across a bridge to catch the bus.

Effect: Mr. Nixon protested to the bus company.

Explanation:

According to a different source, this is the excerpt that comes with this question:

Another time he went to see about extending the route of the Day Street bus. Black people in a little community on the other side of the Day Street Bridge had to walk across the bridge, about half a mile, to get to the bus. Mr. Nixon went down to the bus company to protest. He was always going down to the bus company to protest; sometimes he went by himself, sometimes he took someone with him. He himself did not ride the buses—he had his own car; but he was acting on behalf of the community. The bus company told him that as long as the people were willing to walk the half mile and then pay to ride the rest of the way downtown, they had no need to extend the bus line.

This is the statement that describes the cause-and-effect relationship that is presented in this text. In this excerpt, we learn about the actions of Mr. Nixon. We learn that people had to walk across a bridge in order to be able to catch the bus. This was the cause, as it was the reason why Mr. Nixon decided to protest. Therefore, the fact that Mr. Nixon protested to the bus company is the effect.
