Answer:
Human Life is not eternal, but nature is
Step-by-step explanation:
The tide rises, the tide falls,
The twilight darkens, the curlew calls;
Along the sea-sands damp and brown
The traveller hastens toward the town,
And the tide rises, the tide falls.
Darkness settles on roofs and walls,
But the sea, the sea in the darkness calls;
The little waves, with their soft, white hands,
Efface the footprints in the sands,
And the tide rises, the tide falls.
The morning breaks; the steeds in their stalls
Stamp and neigh, as the hostler calls;
The day returns, but nevermore
Returns the traveller to the shore,
And the tide rises, the tide falls.
The repetition of the phrase, the tide rises, the tide falls, shows how eternal nature is. The waves with soft, white hands show that nature is not cold and unfeeling, so option D is out.
The effaced footprints and the traveller never returning makes option A wrong.
Option B just doesn't fit, seeing as long lives and death was never really explored in the poem.
So we're left with option C, which makes sense. The traveller never again returns to the shore, but the day returns. This shows how nature is eternal, and people are not.
