Final answer:
In "Girl," by Jamaica Kincaid, 3) the girl's dialogue is shown in italics, helping to differentiate her speech from that of the mother's.
Step-by-step explanation:
In the short story "Girl" by Jamaica Kincaid, the reader can discern when the girl is speaking because 3) her dialogue is indicated with italicization.
Unlike other methods such as using quotation marks or parentheses, the story uses italics to signal the girl's words.
This is a stylistic choice that helps to differentiate her voice from the main flow of the mother's lengthy, instructive speech.
It is important for readers to identify these shifts in voice to fully understand the dynamics of the conversation and the characters' relationship.
Dialogue in literature often reveals character and relationships; in "Girl," the brief italicized responses give us insight into the girl's character and her relationship with her mother.
