Final answer:
Frances experiences fear and unease while in the parlor due to its gloomy atmosphere and the mysterious sounds and discoveries she encounters, such as the hidden door.
Step-by-step explanation:
Being in the parlor induces fear and unease in Frances. The text describes how Frances sneezed and rubbed the dust from her watering eyes, signalling discomfort. Additionally, Frances is alone in the gloomy parlor, a setting that is often associated with ghost stories that she enjoys sharing with the other house girls. Her reassurance that it is just a mouse when she hears a rustling, and her gasp when her sleeve brushes the sheeted piano, reflect a heightened state of nervousness and apprehension. The hidden door discovery further adds to the suspense and her sense of unease. Therefore, the correct answer to how being in the parlor affects Frances is B. It induces fear and unease in her.
