Final answer:
The passages explore emotional and physiological changes signified by a character's pallor, showcasing a literary technique in English literature that reflects characters' internal states through physical descriptors.
Step-by-step explanation:
The excerpts provided allude to characters experiencing a range of emotions, notably concern and transformation, with a recurring focus on the physical signifier of pallor. This thematic emphasis falls within the realm of English literature, specifically the analysis of literature's craft and structure.
In multiple passages, the description of a character's paleness is used to convey a deep emotional or physiological change.
In the first passage, a character's initial joy fades to pallor, indicating a sudden emotional shift. Similarly, the second excerpt discusses a diminishing birthmark, with Aylmer's anticipation of success causing his paleness, while the third passage uses robust health as a counterpoint to express doubt and suspicion.
These excerpts require an understanding of how physical descriptions can reflect emotional states, common in the analysis of characters in English literature.
The use of paleness to signify well-being or distress is a literary technique that is explored in high school English classes, particularly when studying characterization and thematic elements of a work.
