Question

read the excerpt from \what to the slave is the fourth of july?\
when the dogs in your streets, when the fowls of the air, when the cattle on your hills, when the fish of the sea, and the reptiles that crawl, shall be unable to distinguish the slave from a brute, then will i argue with you that the slave is a man!
what effect does the repetition of the word when have?
o the repetition gives the excerpt a philosophical quality.
o the repetition distracts readers from douglasss original point.
o the repetition clarifies the time in which the speech was delivered
o the repetition reinforces douglasss incredulity at the oppositions attitudes.

Explanation:

Douglass uses "when" repeatedly to show a series of absurd conditions (animals can't tell slave from brute). This emphasizes his disbelief (incredulity) at those who oppose his view (that slave is a man). It's not about philosophical quality (no deep - thought concepts), not a distraction (focuses on his argument), and no time - clarifying (no date - related info).

Answer:

The repetition reinforces Douglass’s incredulity at the opposition’s attitudes.
