Which of the following indicates that a horse is receptive to something new during its first experience?

Licking or chewing is a common behavior that indicates a horse is processing new information or experiences. When a horse is exposed to something unfamiliar, this behavior often suggests curiosity and a willingness to engage with the new stimulus. It is a sign that the horse is calming down and integrating the experience, as licking and chewing can reflect the horse's approach to situational assessment and emotional regulation.

In contrast, behaviors like running away typically indicate fear or a strong aversion to a stimulus, suggesting the horse is feeling threatened rather than receptive. Paying attention to surroundings often indicates awareness but does not necessarily show a positive reception to new experiences—it could simply reflect vigilance. Yawning can be a sign of stress or boredom rather than engagement, as it can indicate a horse’s effort to relieve anxiety.

Overall, licking or chewing reflects a more positive response, suggesting that the horse is receptive and open to the new experience, making it the correct choice in this context.
