Answer: The following two lines depict the setting of the passage in the best possible way.
It is a great Dead Place—greater than any Dead Place we know.
Everywhere there are the ruins of the high towers of the gods.
Explanation: The given passage describes the circumstances after a highly catastrophic event. The line ' It is a great Dead Place—greater than any Dead Place we know' conveys the fact that the land is devoid of any human presence. At the same time, the line ' Everywhere there are the ruins of the high towers of the gods' describes that the narrator is surrounded by ruins of mighty architectural structures.
Thus, both the sentences appropriately convey the circumstances of complete disintegration of human civilization in the post-apocalyptic world.
