Read the excerpt from the poem "Barbara Frietchie.”

I WILL GIVE BRAINLIEST TO WHOEVER IS CORRECT:)

All day long through Frederick street

Sounded the tread of marching feet:

All day long that free flag tost

Over the heads of the rebel host.

Which is most likely the author's purpose in using "all day long” in two successive rhyming couplets?

A: to help readers visualize the flag

B: to foreshadow what will happen next

C: to reflect what happened in the past

D: to emphasize a specific time frame

D: To emphasize a specific time frame.

Explanation:

The poem Barbara Frietchie by John Greenleaf Whittier talks about the bravery and defiance of the old lady Barbara Frietchie amidst the march of the Confederate armies under General Jackson. Her love and respect for her country's flag influenced and touched the general's heart who promised to kill anyone who attacks the old woman.

The repetition of the rhyming couplet "all day long" in the two lines of the poem is to lay emphasis on the specific time frame that the flag remained fluttering in the wind. The flag's time in the wind and the marching of the armies corresponds to each other.  

Thus, the correct answer is option D.
