These pictures each show one direction of a two-lane street, and a stick figure waiting to cross the street. If the figure has normal hearing and walking speed, could he hear the cars coming from that direction well enough to know that it would be clear for him to cross whenever it is quiet and he hears nothing coming?
Select the Yes link if he could hear, or the No link if he could not hear - we'll tell you if you are correct or not.
