Answer:
How such enormous monuments
were moved across the land is a mystery, and
when asked to reveal the secret the chief will
say only, with a wry smile. "They walk"
Explanation:
Personification is a literary device in which an inanimate object is given human attributes.
The writer is filled with a sense of wonder how the inhabitants of the island were able to move the huge and obviously heavy 30-feet high stone statues. When he inquired of the chief how the stones got there, the Chief replied that the monuments walked there.
The stone statues are inanimate objects and so cannot walk. Saying that the stones walked which would even heighten the writer's astonishment, assigns them a human attribute.
Thus, the sentence best uses personification to show the writer's sense of wonder.
