(单选题)

A horse’s ears are special because they can ______.

A.send messages

B.turn to different directions

C.sense temperatures

D.clear out the dust

参考答案：A

参考解析：

细节理解题。根据文章第三段第一句“By watching the ears, you can get clues to what the horse is hearing.”以及最后一句“Though these actions may be natural responses and not deliberate communications, they help you know what the horse is thinking.”可知，马在听到不同的声音以判断情形时会变化耳朵的样子，根据形状可以判断信息，所以可以通过马耳朵形状的变化获取信息，故选A。
