List an example of a non-verbal communication strategy.

Using gestures or facial expressions to convey messages is a clear example of a non-verbal communication strategy. This form of communication relies on visual signals rather than spoken or written words to express thoughts, feelings, and intentions. Non-verbal cues can greatly enhance or even modify the meaning of verbal communication, providing context or emphasizing a point.

Gestures, such as waving or pointing, and facial expressions, like smiling or frowning, can communicate a wide array of emotions and reactions effectively. This is particularly valuable in diverse settings, where language barriers may exist, allowing individuals to understand each other through universal signals. Additionally, non-verbal communication can demonstrate empathy and engagement, making conversations more meaningful and responsive.

Other answer choices involve verbal expression (speaking and singing) or written communication (writing notes), which do not fall under the category of non-verbal strategies, as they rely heavily on language or text rather than physical cues or actions.
