Step-by-step explanation:
The author of a text can convey what they want the reader to know through various techniques. Firstly, the author can use figurative language such as metaphors, similes, and descriptive imagery to create a more immersive and vivid experience for the reader. This allows the author to effectively convey their message or theme through the use of powerful and evocative language.
Secondly, the author can demonstrate awareness of the rhetorical situation, including aspects such as the narrator, audience, purpose, context, and culture. By considering these elements, the author can tailor their writing to meet the specific needs and expectations of the intended audience, effectively conveying their intended message or information.
Lastly, the author can employ technical language associated with visual rhetoric.
