Step-by-step explanation:
The student's question, "What was Mrs. Sommers thinking about on the cable car?", explores the character's thoughts from the short story 'A Pair of Silk Stockings' by Kate Chopin. Unfortunately, the provided excerpts from different literary works do not include a passage from 'A Pair of Silk Stockings,' and thus there is no contextual evidence to accurately answer this specific question.
Mrs. Sommers is known to have reflective and contemplative moments about her personal desires versus her responsibilities, especially after acquiring a small amount of money, which she ultimately decides to spend on herself for a change. It is in these moments on the cable car where she likely ponders her newfound freedom and the pleasures she can afford with her limited funds.
