Answer:
"As each slaty wall of water approached, it shut all else from the view of the men in the boat, and it was not difficult to imagine that this particular wave was the final outburst of the ocean, the last effort of the grim water.”
Step-by-step explanation:
The open boat was an account of survival of shipwreck by a correspondent. It was first published by Stephen Crane in 1897.
It states the experience of Crane a newspaper correspondent that was involved in a shipwreck of the coast of Florida on his way to Cuba.
He and 3 other men navigated their way to shore in a boat.
The excerpt that confirms the theme of the ocean being relentless and indifferent is - "As each slaty wall of water approached, it shut all else from the view of the men in the boat, and it was not difficult to imagine that this particular wave was the final outburst of the ocean, the last effort of the grim water.”
This portrays the way the ocean had control of their boat, and persistence in how it tries to capsize them.
