Answer:
The sentence which describes the difference between the two poems is:
C. Auden mentions a ploughman and a ship as witnesses to icarus’s fall, while Williams only mentions a farmer
Explanation:
Both poems are based on a painting that portrays the fall from the sky of the mythological character Icarus. According to the myth, Icarus made wax wings so that he could fly. However, having flown too close to the sun, his wings melted and he fell.
<u>According to Auden's poem, a ploughman and a ship were witnesses to such a tragedy. No one, however, did anything to help poor Icarus:</u>
<em>[...] the </em><em>ploughman</em><em> may
</em>
<em>Have heard the splash, the forsaken cry,
</em>
<em>But for him it was not an important failure; the sun shone
</em>
<em>As it had to on the white legs disappearing into the green
</em>
<em>Water, and the expensive delicate </em><em>ship</em><em> that must have seen
</em>
<em>Something amazing, a boy falling out of the sky,
</em>
<em>Had somewhere to get to and sailed calmly on.</em>
<u>Williams, on the other hand, only mentions a farmer (who is in fact the same ploughman). He does not mention the ship:</u>
<em>a </em><em>farmer</em><em> was ploughing</em>
<em>his field</em>
<em>the whole pageantry</em>
<em>of the year was
</em>
<em>awake tingling
</em>
<em>with itself
</em>
