Which term means to listen to or give attention to?

The correct term that signifies the action of listening to or giving attention to is "hear." This term specifically implies the physical act of perceiving sound, which is essential in the context of listening. When someone hears, they are actively engaged in receiving auditory information, which is a foundational skill for communication and understanding.

In contrast, the other terms refer to different forms of perception or engagement that do not center exclusively on listening. For example, "watch" pertains to the act of actively looking at something, often involving visual observation rather than auditory attention. "Observe" also denotes the act of watching or noticing something carefully, which again is more visually oriented. Lastly, "perceive" encompasses a broader range of sensory inputs, including sight, sound, taste, touch, and smell, rather than focusing solely on the act of listening.

Understanding each term's specific meaning clarifies why "hear" is the most appropriate choice for describing the act of listening or giving attention to sound.
