1 I know what the caged bird feels, alas! When the sun is bright on the upland slopes; When the wind stirs soft through the springing grass, And the river flows like a stream of glass; When the first bird sings and the first bud opens, And the faint perfume from its chalice steals-- I know what the caged bird feels! What two things are compared in a simile in the first stanza of this poem? A) a bird and the sun B) a bird and a river C) perfume and springing grass D) the river and a stream of glass
