Quizplus · Accepted Answer

An auditory signal is typically brief and can work among obstructions at night since sound waves can travel through obstacles such as trees and buildings. Olfactory signals are based on smells and are not effective at night, while visual signals require light, which may not be present during the night. Magnetic signals are not used in communication.
