<span>#1) Which pair of lines from the passage contains a change in intonation?
Answer: After carefully reading the passage from “Mother to Son” by Langston Hughes I came to the conclusion that the pair of lines from this passage that contains a change in intonations is the following: But all the time / I’se been a-climbin’ on. This intonations can help us distinguish the meaning. It is all focused on the pitch and stress going up and down.
