Read the following scenario and answer the question below. Thousands of young families moved ʺover the hillsʺ and into the San Fernando Valley, a suburb of Los Angeles, after World War II. New neighborhoods were springing up, replacing orange groves and open space; roads and schools quickly sprang into existence, trying to keep pace with the rapid population growth.

On warm afternoons, eyes would sometimes sting and burn. People would stop, close their eyes, and let the cleansing tears refresh irritated eyes. They accepted this as a normal part of life in sunny California. -In the 1950s, Los Angeles became famous for its smog. One part of the problem was _________________
