Detailed Solution

The above statement is False.
A sound is basically a sequence which can propagate through a compressible medium like water or air, or any solids. As molecules in the solids are very close to each other than any other form of matter, this allows sound waves to travel rapidly, and so during wartime, Red Indians put their ear to the ground to hear the vibrating sound of the enemy’s feet, even from large distance away as the sound travels fastest through the solids and not to check water levels inside the earth.
The correct statement would be red Indians put their ears to the ground to track enemy’s movement.
