Question
In 1958 trash collection programs were established, and backyard incinerators were banned in the hope of reducing smog. However, it was estimated that massive amounts of gasoline were evaporating from storage tanks, fuel pump nozzles, and delivery trucks.

There was still a great deal of smog, now identified as photochemical smog, despite the changes. The major remaining problem was ________.A) indoor pollution from new houses, with new furniture
B) the influx of new manufacturing, with new chemicals
C) too many coal-fired power plants along the coast
D) the large distances travelled daily by solitary commuters
