• Hint:
  • Consider the possibility of an unseen force or phenomenon.
• Answer:
  • The crop damage was caused by strong winds at night. The camera’s motion sensors were not sensitive enough to detect the wind, and the damage occurred so quickly that it was not captured on film. To protect his crops, the farmer installed windbreaks around the field.

10.3.4 Problem

In a remote village nestled amidst towering mountains, a strange phenomenon occurred. Every night, a faint but persistent humming sound filled the air, keeping the villagers awake and on edge. The sound seemed to emanate from the surrounding mountains, but no one could pinpoint its source. Some villagers believed it was a supernatural occurrence, while others feared it was a sign of an impending disaster. What was the true cause of the mysterious humming sound, and how could the villagers find peace and quiet?

• Hint:
  • Think about the geological characteristics of the area.
• Answer:
  • The humming sound was caused by the vibrations of a nearby underground river. As water flowed through the narrow passages of the river, it created a resonant frequency that was amplified by the surrounding rock formations. To mitigate the sound, the villagers constructed a series of small dams and channels to redirect the water flow and reduce the vibrations.

10.3.5 Problem
