Evaluate the last line of the novel Of Mice And Men: "And Carlson said, 'Now what the hell ya suppose is eatin' them two guys?'" How does this quote prove that the title of this book is appropriate?

Carlson´s words show that he´s incapable of understanding George´s remorse over having just killed his best friend, Lennie. This is a reference to the title of the novel which was taken from Robert Burns' poem "To a Mouse".

Explanation:

In the poem, Burns expresses his remorse over the accidental destruction of a mouse’s home while he was working in a field. A similar remorse George is feeling at the end of the novel.

alone =having no one else present.
