Final answer:
The subject of this question is English because the question is asking for the truthfulness or falsehood of a statement. The passage provided does not provide enough context to determine the specific topic being discussed.
Step-by-step explanation:
The question seems to be asking whether Cora became proficient at picking out the weak from a crowd with her evil eye, which is a bit unclear without context. However, from the provided excerpts, we can develop a response that revolves around the themes of sight, perception, and judgement which recur in the narratives. The characters appear to possess or struggle with the ability to see beneath surfaces or to influence others through vision or appearance.
For instance, Jane Withersteen's experiences of betrayal and her attempts at placating Lassiter suggest that Jane had to learn to see past her initial perceptions and use 'womanly allurement' to influence him. Deborah's sense of hopelessness is juxtaposed with her gaze upon the 'bright, unattainable calm' of the hills, indicating a longing for something beyond her grasp, and also demonstrating sight as a metaphor for insight or understanding. Meanwhile, the story of a character developing a sense of what he might become reflects an internal vision—seeing a version of oneself that aspires to positive change.
These examples show the profound effects of sight, both literal and metaphorical, on perception and action. They display how characters both see and are seen, how they perceive themselves and others, and how they are influenced by that perception.
