Which of these lines contains poetic language that conveys a sense of gentleness?
O And the eyes of those two Indian ponies
Darken with kindness.
She is black and white,
Her mane falls wild on her forehead,
O We step over the barbed wire into the pasture
Where they have been grazing all day, alone.
O At home once more,
They begin munching the young tufts of spring in the darkness.
