"[but someone still was yelling out and stumbling
and floundering like a man in fire or
[dim, through the misty pines and thick green light]
[as under a green sea, i saw him drowning.]

[in all my dreams, before my sight,
he plunges at me, guttering, choking, drowning.]

[if in smothering dreams you too could pace]
behind the wagon that we flung him in,
and watch the white eyes writhing in his face,"

the options are the sentences in the brackets.
