The correct answer is a subject and a verb~
Answer: The king believed that his son had drowned.
Explanation:
We have learned previously through Prospero and the familiar spirit that is, Ariel’s conversation, that it was Ariel who caused the tempest which struck the ship transporting Alonso, Gonzalo, Sebastian, Ferdinand, Antonio, Stephano, and Trinculo, by making sure that they got safely to the island but that they were divided into small groups.
On another part of the island, Sebastian, Antonio, Alonso, Gonzalo, and other lords were giving thanks for their safety but were worrier about the fate of Ferdinand.
Alonso ended up in a group that had Gonzalo, Sebastian, Antonio, and they were afraid that Ferdinand may have been drowned. This made Alonso regrets marrying his daughter which was the reason they made the sea journey.
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.
