Which option describes a warning sound according to the material?

• A. Low frequency, noisy growls
• B. Yelps
• C. Barks
• D. Purrs

Answer: (A)

Warning vocalizations are typically low-pitched and convey a boundary or threat before escalation. The description low frequency, noisy growls fits this purpose—it's a sound that tells others to back off and signals potential danger without immediate aggression. Yelps are high-pitched distress calls, indicating pain or fear rather than a warning. Barks can signal alert or agitation but aren’t specifically the warning boundary signal described here. Purrs usually express calm or contentment and don't communicate a warning. So, the low frequency, noisy growl best matches a warning sound.
