길이도 짧고 컨텐츠도 없는 걸로 봐서는 RL 기출일 것 같습니다
음성은 여기인데 잘 안 들리고 이해가 안가서 찾아봤는데

(놀자, 낯선 사람이 접근할 때, 음식 보호용)
음식 보호용에서만 물러서고 나머지 2종류에서는 bone 가져감
이 실험은, 개는 다른 타입의 으르렁거림을 구별할 수 있다는 걸 알려줌
첫번째 예에서 another dog plays for snallz 는 못 알아듣겠네요
growls (으르렁거림)

Researchers recorded an "alone bark", a stranger growl where a dog was growling at the approach of a stranger, and a "food growl" where a dog was growling to protect its food.
The researchers played these different growls to a dog who was approaching a plate of juicy food. The dogs were more hesitant to approach if they heard the food growl rather than the stranger growl or the alone barks.
The experiment shows that dogs could clearly distinguish between different types of growls, and react to them accordingly.
