Answer:
The phrase "the edge of the sea concerned / with itself" most strongly suggests:
A) The sea continues to break on the shore despite Icarus's drowning.
Explanation:
"Landscape with the Fall of Icarus", by William Carlos Williams, is a poem that describes a painting by Pieter Brueghel. The painting depicts the mythological character Icarus falling from the sky into the ocean as his wax wings are melted by the sun. The poem and the painting convey the same idea that the world goes on without consideration for the suffering of a being. Not one person, one thing, was disturbed by Icarus's fall. As the lines say, "the edge of the sea concerned / with itself", meaning the ocean itself is not disturbed. Icarus has just fallen inside it, but the sea continues to break on the shore as if nothing has happened, as if no one had died.
I like the manga's "angels of death" and "demon slayer" (you probably already know demon slayer if you like manga/anime). angels of death is a good manga, though it has a lot of blood in the anime. Also, it might get a bit boring.
The two words Bradbury uses repeatedly in this scene are "The beetle". The repetition adds to the suspense of the scene. Each time "the beetle" is repeated the reader can feel the car getting closer and closer. Because the sentences are very short and similarly structured, they speed up the pace of the scene just like the car is picking up speed.
