Step-by-step explanation:
The use of devices such as similes, metaphors and personification are usually employed by authors because doing so can add depth of meaning to their writing. When an author presents his or her writing to the reader, the presence of these literary devices can make the reader more interested in the text. It can also make the process of reading the text more dynamic, and add a layer of complexity to the text.
