Answer:
Nature obscures the signs of human turmoil.
The sacrifices of war are soon forgotten.
Step-by-step explanation:
Those are the two options above. The first is correct because in the poem when the conductor was chugging the train, the people did not know where the place was anymore after 10 years passed because the grass has overgrown and the landscape has changed.
The second option is correct because at the beginning of the poem he discusses or talks about how the grass will cover up the dead bodies, so people have slowly forgotten about the things that happened in the war because the grass is covering up those bodies.
