- Read the poem below and answer the questions that follow.(Solved)
Read the poem below and answer the questions that follow.
Make me a grave whate’er you will,
In a lowly plain, or a lofty hill,
Make it among earth’s humblest graves’
But not in a land where men are slaves.
I could not rest if around my grave
I heard the steps of a trembling slave,
His shadow above my silent tomb
Would make it a place of fearful gloom.
I could not rest if I heard the tread
Of a gang to the shambles led.
And the mother’s shriek of wild despair
Rise like a curse on the trembling air.
