The poem below is by the American poet Carl Sandburg. He refers in the poem to five battlefields where many died (Austerlitz, Waterloo, Gettysburg, Ypres, and Verdun).
Grass
Pile the bodies high at Austerlitz and Waterloo.
Shovel them under and let me work—
I am the grass; I cover all.
And pile them high at Gettysburg
And pile them high at Ypres and Verdun.
Shovel them under and let me work.
Two years, ten years, and passengers ask the conductor:
What place is this?
Where are we now?
I am the grass.
Let me work.
The poet implies that?
a. time passes too slowly.
b. wars scar the land forever.
c. even bloody battlefields can be cleansed by time and nature.
