What additional line best matches the tone of the stanza?

"the caged bird"

The first two stanzas contrast two birds. Lines 1 through 7 describe the actions of a bird that is free; it interacts with nature and "dares to claim the sky." The second stanza (lines 8 through 14) tells of a captured bird that must endure clipped wings, tied feet, and bars of rage; yet he still opens his throat and sings. The third and fifth stanzas are identical. Lines 2, 4, and 6 and lines 5 and 7 of these identical stanzas rhyme. The repetition of the third stanza gives some predictability to the poem and allows the reader to participate actively in the unpleasant plight of the caged bird.
