Final answer:
Lena heard the rasping of tin on bars, suggesting someone was occupied with an object, while Kismine heard voices mentioning her father's slaves. The Nightingale, on the other hand, heard night sounds from her position in the holm-oak tree.
Step-by-step explanation:
Lena, a character from one of the literary excerpts, heard the rasping of tin on bars, as someone named Hugh was at his old amusement again.
This situation could signify either an escape attempt or a habitual activity that brought little comfort to Lena, as indicated by her shivering. In contrast, the character Kismine heard something different; she was standing near the window in an angora kimono and, upon John's entrance, whispered about hearing “them.”
This suggests she heard voices, specifically mentioning her father's slaves. Lastly, the Nightingale, from a different narrative, heard the night sounds as she looked out through the leaves of the holm-oak tree, driven by curiosity or concern. The various scenes depict characters who are attentive to their surroundings, highlighting the importance of auditory elements in literature to convey tension, curiosity, or the general atmosphere.
