What is the main factor that determined the survival of different winged moth populations?
  1. Their ability to camouflage themselves against their background
  2. Their reproductive rate
  3. Their resistance to pollutants
  4. Their food availability

Solution

The main factor that determined the survival of different winged moth populations is their ability to camouflage themselves against their background. The white:winged moths were able to survive before industrialization because they could hide in the background of the almost white:colored lichen on the trees, while the dark-winged moths were able to survive after industrialization because they could hide in the darker background caused by industrial smoke and soots.
