Final answer:
Without a specific reference to Flora and her reaction to a figure across the lake in the provided texts, a precise answer cannot be given, as the extracts discuss various characters' intimate moments with nature and encounters with beauty.
Step-by-step explanation:
The query regarding Flora's reaction to the figure across the lake suggests a need for interpretation of a literary text. Based on the provided extracts, it is not entirely clear which figure on the other side of the lake is being referred to. Nevertheless, the understanding of a character's reaction, such as Flora, would require analyzing the context, description, and actions presented in the text revolving around the encounter with the figure. The extracts appeal to senses, describe intimate encounters with nature, and contemplation of beauty, all of which could be relevant depending on which text Flora's encounter comes from. However, without direct reference to Flora and specific circumstances of her sighting the figure, a precise explanation of Flora's reaction cannot be confidently provided.
