Final answer:
The question pertains to the English subject and involves analyzing literary devices like imagery and metaphor found within descriptive passages, likely for high school students studying literature.
Step-by-step explanation:
The passages provided all evoke strong imagery and emotion, which is a characteristic element of literary analysis within the English subject, particularly when discussing prose and poetry. These excerpts likely come from literary texts and demonstrate various literary devices such as imagery, metaphor, and personification. Descriptive phrases like "The yellow fog that rubs its back upon the window-panes" and "The dry brown coughing beneath their feet" serve to create a vivid picture in the reader's mind, setting a scene or conveying an atmosphere in a unique and powerful way.
Understanding these elements is important for interpreting literature and writing analytically about it, which are skills typically developed at the high school level. Each excerpt uses descriptive language and metaphor to communicate not just a scene, but the emotion or mood of that scene, which are key aspects of literary study.
