Which word best illustrates the mood of the poem?
nothing gold can stay
by robert frost
nature's first green is gold
her hardest hue to hold
her early leafs a flower
but only so an hour
then leaf subsides to leaf
so eden sank to grief
so dawn goes down to day
nothing gold can stay

impermanence

Explanation:

The excerpt talks about subsiding and how some things can't "stay" for some reason which is depicted in earlier lines.

I'm making a assumption that the poem intends that, nothing gold can stay. like a leaf eventually will die and a tree will wither away and the sun will turn into the moon, basically nothing stays the same, eventually time will go forward and things will change. makes sense?

Explanation:

wordsworth tends to see nature as 'out there'; a presence which surrounds humans, and contributes to human life, but is different from humans. if you look at a typical wordsworth poem (there was a boy, ye knew him well ye rocks) - wordsworth talks about nature as something that needs to be learned about and understood, nature is different from us.  

if you look at a byron poem (the isles of greece is a good one) - byron looks at nature mainly for what it already means to man. wordsworth will look at a landscape and see the mountains, trees, valleys, and rivers as almost spiritual presences - wordsworth wants to get to know nature.  

byron will look at the same landscape and he will want to know who lives there, what are the villages? are there any farms or mines, is there some history?  

wordsworth looks at nature for what it is; byron is forever asking what it means.  

wordsworth thinks that humans are part of nature; byron thinks that nature is part of being human
