Final answer:
1) Her beauty is unmatched by any other woman. The excerpts provided suggest that Daisy Miller's beauty is considered quite remarkable, possibly unmatched, and exceptionally striking, as inferred from the descriptions and reactions of the character Winterbourne and through poetic imagery.
Step-by-step explanation:
Based on the excerpts provided, it seems that Daisy Miller's beauty is acknowledged by the characters in the stories, particularly in the lines where Winterbourne thinks, "No; it's impossible to be prettier than that". This indicates that, at least in the eyes of Winterbourne, Daisy's beauty is quite remarkable and possibly unmatched by other women he has observed.
Furthermore, another excerpt describing a young girl with prettiness visible in the darkness and opening and closing an enormous fan suggests a charming and attractive presence, which compliments the idea of Daisy's distinctive beauty.
Lastly, the poetic lines "Her eyes as stars of Twilight fair; Like Twilight's, too, her dusky hair; But all things else about her drawn From May-time and the cheerful Dawn;" contribute to the portrayal of Daisy as a luminous and alluring figure, enabling us to infer that Daisy's beauty is likely seen as exceptional and certainly more striking than just average when compared to other women.
