Which line of this excerpt from "Ozymandias" by Percy Shelley reflects the theme that art alone can last forever?

Explanation:

"Ozymandias" is a poem by Percy Shelley. It talks about the foolish desire of the Eygptian King Ramesses who built  a statue of himself in the bid to immortalize himself.

The statue was broken and the face that was left depicted the king's expressions and emotions. These expressions and emotions will be after his death; even after his death, his expressions has been inscripted on the statue.

Therefore, the line "nothing beside remains round the decay" simply says,  "that art alone can last forever" which gives the insight that even after king dies and his life gone and decayed,  the statue as an art will still live on.

the purpose of the heading in the passage is to identify who is telling the story.

this excerpt is part of the book sugar changed the world (2010) written by marc aronson and marina budhos. as the book has been written by two people, the heading "marc" indicates that this specific excerpt is being narrated by aronson. in the fragment, marc describes his grandfather's story after hearing it from his cousin. however, there are other excerpts where budhos is the one that tells the story of her family.

aronson and budhos, who are husband and wife in real life, decided to write sugar changed the world when they found out how sugar, which had an important role in slavery and economy, changed their ancestors' lives.
