Final answer:
The provided text best exemplifies the use of imagery, as it vividly describes the conflict between the spiritual and the material aspects of being, allowing readers to engage their senses and imagination.
Step-by-step explanation:
The excerpt you've provided best describes the use of imagery. Imagery in literature is a device used to create a vivid and graphic presentation of a scene that appeals to as many of the reader’s senses as possible. It aids the reader’s imagination to envision the characters and scenes in the literary piece clearly. Other literary devices mentioned, like allegory and metaphor, are present in other forms of writing. An allegory is a narrative with a double meaning: a primary or surface meaning; and a secondary or under-the-surface meaning. A metaphor, on the other hand, is a figure of speech that compares two different things by stating one is the other. The provided text uses descriptive language to paint a picture of the internal conflict between a person's spiritual self and their earthly being, making strong use of sensory details that characterize imagery.
