According to poem of "Desert Places" by Robert Frost please give the response to the following question:1.which stanza is most negative?consider...

I'm not sure what you mean by "consider synonyms," but to me, the most negative stanza in this poem is the last one (although I should say that the whole poem feels quite negative to me).

I say this is the most negative because it seems to express such loneliness and isolation and fear.  He says that what is inside him is much scarier than anything outside -- more frightening than the vacuum of outer space, more frightening than dark fields that make him feel alone.  This is a very bleak idea.
