Final answer:
The student's inquiry about leftovers from a sandwich line is a thematic element tied to the representation of resources in literature; works like Susan Glaspell's 'Trifles' and Frank Norris' 'McTeague' symbolically utilize such remnants to depict societal views and conditions.
Step-by-step explanation:
The student's question about what happens to leftover breads from a sandwich line at the close is indirectly exploring a thematic element found within English literature and texts. It is not directly related to food management practices but could be a reference to the way resources and food are depicted in literature.
In Susan Glaspell's play 'Trifles,' for example, Mrs. Peters discovers bread set aside, which symbolizes the mundane and undervalued domestic work done by women during that era. Meanwhile, describing the setting in Frank Norris' 'McTeague,' the text paints a vivid image of the town with desolate landscapes, such as the mud bank left bare by the tide, and urban industrialization represented by the gas-works and iron foundry.
Both instances from literature address how leftovers or remnants can play a role in thematically representing aspects of life and society within a story.
