The Last Question: He Explains his departure as the Movement from one part of his Life to another.
Here are the lines the contain personification:
-<span>The high mountain wind coasted sighing through the pass and whistled on the edges of the big blocks of broken granite. . . .
-</span><span>And behind the flat another mountain rose, desolate with dead rocks and starving little black bushes. . . .
Basically, when we say personification, this is one of the figures of speech which attributes the characteristics of humans to something that is not human.</span>
A story's theme is the central idea or insight about life or human behavior.
Hope this helps! Have a nice day!
