Based on the table, the velocity of sound in water is the highest, followed by soil, grass, and then air. Therefore, the boy swimming in the water would be able to hear the rock falling off a cliff one kilometer away the best, as the sound would travel the fastest through water. The other boys would also be able to hear the sound, but their ability to do so would be less efficient compared to the boy in the water.
