Final answer:
The language of Mary Shelley's 'Frankenstein' likely produces an eerie and foreboding tone, as it is characterized by a gothic genre with supernatural elements and the use of dark, descriptive language that evokes dread.
Step-by-step explanation:
To determine the tone of an excerpt from Mary Shelley's Frankenstein, one must assess the words, phrases, images, or snippets of dialogue used throughout the text. In this case, considering the gothic genre and elements of Frankenstein, which typically include supernatural occurrences, monsters, and an exploration of the unknown, the language of the excerpt most likely contributes to an eerie and foreboding tone. This tone is consistent with Shelley's use of dark, descriptive language that often evokes feelings of dread or apprehension, emphasizing the presence of mystery and the supernatural. The tone could be indicated by a cool and detached narrative voice, irony, or the use of specific diction that intensifies the reader's interest, causes uneasiness, or provokes fear. For example, words like 'ghastly', 'dreary', or 'ominous' would all contribute to such a tone, setting a mood that is anything but uplifting or joyful.
