Question

Vocal signals are used by _____.  
A) wolves
B) mice
C) snakes only
D) lizards only
E) snakes and lizards

Accepted Answer

Wolves are known to use vocal signals for communication, including howling, growling, and barking. While some other species may also use vocalizations, the answer choices of mice, snakes only, and lizards only are too specific, and the answer choice of snakes and lizards is broad and not necessarily accurate.
