Read the excerpt from dr. martin luther king jr.’s "i have a dream" speech.

this is our hope. this is the faith that i go back to the south with. with this faith we will be able to hew out of the mountain of despair a stone of hope. with this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. with this faith we will be able to work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day. this will be the day, this will be the day when all of god's children will be able to sing with new meaning:

my country, 'tis of thee, sweet land of liberty, of thee i sing.
land where my fathers died, land of the pilgrim's pride,
from every mountainside, let freedom ring!

which is the best example of a metaphor?

this is our hope
mountain of despair
pray together
sing with new meaning
