D. Personification is your answer
You need to be able to write the myth in your own words. Libraries are a more modern idea that was not around in the Greek times.
If you would like to go in that direction anyway, why not rewrite the story of Athena and Arachnid but instead of weaving tapestries, have them write stories using thread to each write a book on cloth, much like the old-fashioned samplers. The "books" would hang on the wall in olympus and tell their stories, like a sampler. This inspired mortals to write stories for themselves and use murals, and papyrus to write upon and share their books, becoming the first library.
A tip i can give you is to use a topis that you are strong about. Forexample, if you strongly believe that state tests should not be administered you should use that. But ypou need evidence to back this claim up. If you dont, then the essay wont be per<span>suasive</span> it will only be an opinion that people wont believe.
