Why does the author say what they see is an increasingly appalling landscape? (Para. 5)
A.
There's smoke on the horizon, the blaze of battle fading.
B.
We pass by deserted villages, solitary, burned-out houses.
C.
We pass battlefields dense with the garbage of abandoned war equipment, bombed-out railway stations, overturned cars.
D.
It smells of gunpowder, and of burning, decomposing meat after a massacre. Everywhere are the corpses of horses.
