Sonar is a tool that uses high-frequency ultrasonic waves for sound navigation and ranging. When this system is used, high-frequency ultrasonic waves are sent out, bouncing off objects and reflecting back to their source. This reflected sound is called an echo. The time taken for each emitted sound to return gives information as to how far away the object is.
From the information given, which of the following would be LEAST LIKELY to use sonar?
A . a bat flying at night looking for food
B . a submerged submarine looking for enemy ships
C . a dolphin navigating underwater
D . a fishing ship looking for schools of fish
E . a honeybee collecting pollen
Answer: E
