Wordsworth is using a positive tone
Answer:
show the sentence or should we give and example to you ?
The poem uses dialect to convey the tone and mood. It also uses refrain, "ain't been no crystal stair" as emphasis. It adds imagery to the reader, "splinters" "tacks" "boards torn up" "places with no carpet" and "bare" which rhymes with stair. After "and places with no carpet on the floor-"
"bare"
The "-" adds a pause, adds emphasis to the exasperation and gives the reader time to take a breath.
"I'se a been a-climbin on" shows strength in the face of hardship. It contributes to the author's purpose by conveying the tone and mood of a working class, black person facing struggles of poverty and misfortune.
I would think it's one of the last two. It is a news article which means it would be important to verify facts and information so that it would be considered trustworthy and you could do this through evidence.
Hope that helps :)
