Read the excerpt from Warriors Don't Cry. "Then you don't have anything to be concerned about." Mother Lois maneuvered through the unusually heavy traffic. "I don't know where all the cars could have come from," she said. We both craned our necks, curious about all the unfamiliar cars and people.

What idea is emphasized through repetition?

Commuter traffic is a daily inconvenience.
The streets are unusually crowded.
The narrator is looking for her friends.
Mother Lois is not a skilled driver.
