The reference text provided does not correspond to 'The Necklace' so evidence from the actual story text is needed to illustrate Mathilde's beauty being too great for her station in life.
The student has asked for evidence from The Necklace that supports the idea of Mathilde's beauty being greater than her social standing. Unfortunately, the provided reference text does not match with The Necklace by Guy de Maupassant, as the text seems to describe various different artworks and historical figures, rather than the story of Mathilde.
The story of Mathilde is about a woman born into a family of clerks who feels she deserves more out of life and is distressed at her middle-class existence.
To correctly answer the student's question, one would cite the actual text from The Necklace, which describes Mathilde's beauty and charm that are inappropriate for her modest social position, such as how she is described as 'pretty and charming' in a life that she finds so modest and unworthy of her beauty.
