In a jungle where there is no streets lights or any other artificial source of lights, I notice a black snake crossing the road.
How did I get sight of snake ?
A black dog stands in the middle of an intersection in a town painted black. None of the street lights are working due to a power failure caused by a storm. A car with two broken headlights drives towards the dog but turns in time to avoid hitting him. How could the driver have seen the dog in time?
