Answer:
Dreary
Step-by-step explanation:
The mood refers to the predominant emotion or feeling in a story, that is created through the choice of words, phrases, and tone used to describe and narrate. The repetition of the word "fog" in the passage symbolizes many things, all of them with a negative and dark connotation: Confusion, obscurity, loss, isolation, mystery or blurring between reality and unreality. This constant and calm repetition of the word "fog" in the writing, evokes in the reader a dull, dreary, and lifeless feeling.
