Final answer:
Clues indicating the setting of 'The Story of an Hour' include the treatment of women's health, the expected behavior of women, and references to health concerns of that era, reflecting the late 1800s societal norms.
Step-by-step explanation:
The story 'The Story of an Hour' by Kate Chopin, written in 1894, reveals its late 19th-century setting through several clues. One aspect is the social and medical attitudes toward women, as evidenced by the 'great care' taken in breaking the news of her husband's death to Mrs. Mallard, highlighting the paternalistic treatment of women's emotional and physical health. Another clue is the restrained behavior expected of women, as noted in the line that language, institutions, and expected demeanor suppress the natural desires and aspirations of women. These elements reflect the historical context of the late 1800s, a time marked by gender norms that were restrictive for women. Additionally, references to elements such as heart trouble as a serious health concern without the modern interventions available today also suggest the historical period. The setting is further emphasized by societal changes from the Industrial Revolution, which had transformed society and the roles individuals played within it.
