Answer:
The sentence that describes a difference between Auden's Musee des Beaux Arts and Williams' Landscape with the Fall of Icarus is:
C) Auden mentions a ploughman and a ship as witness to Icarus' fall while Williams only mentions a farmer
Step-by-step explanation:
Both poem poems describe the same painting by Pieter Bruegel the Elder. The painting shows the mythological character Icarus falling from the sky into the ocean as his wax wings are melted by the sun. The witnesses to his fall keep on living their lives, indifferent to the tragedy that has befallen Icarus.
While Auden's poem mentions the ploughman and the ship from the painting, Williams' mentions a farmer who "was ploughing". It is the same ploughman from Auden's poem, who keeps on working despite the splash he can hear coming from where Icarus fell. Williams does not mention the ship at all, while Auden says it "Had somewhere to get to and sailed calmly on."
