Final answer:
The question seems to pertain to a novel where characters Jem and Scout feel guilty about a snowfall event, possibly referenced in 'To Kill a Mockingbird'. Without specific context or text, a definitive answer cannot be provided. This should be classified under English literature study.
Step-by-step explanation:
The student's question references a moment in a novel where characters Jem and Scout feel guilty after snow falls for the first time since 1885. The specific text or context involving Jem and Scout is not provided, however, as these characters are from the novel To Kill a Mockingbird by Harper Lee, it can be inferred that the students might be studying this novel or another with similar characters. In To Kill a Mockingbird, Jem and Scout experience a rare snowfall in their hometown of Maycomb, which is an event that causes various reactions, but the novel does not contain a direct instance where they feel guilty about the snow itself. In the absence of clear text from the novel that relates to the guilt over the snow, a precise answer cannot be given. The references made are regarding the emotional responses of characters to certain situations, which is a common element studied in English literature to understand character development and thematic expression.
