Step-by-step explanation:
Visual elements can enhance a text by providing additional clarity or by emphasizing an important idea. The answer is A) Clarity, emphasizing. In the field of arts, emphasis is used to draw attention to certain aspects of a piece, creating a focal point. This is achieved using various methods such as contrast in color, or through the strategic placement and isolation of elements in relation to the rest of the composition. For instance, a strongly contrasting color, like gold against dark purple, will make the gold elements stand out. Similarly, when looking at visual information within texts, the use of images can significantly affect how a message is received and understood, providing depth and context beyond the literal meaning of the words. Images can also contribute to the rhetorical effectiveness by fulfilling certain functions, such as setting the tone or mood, or by guiding the viewer's interpretation through symbolic color use.
