Step-by-step explanation:
In Lorraine Hansberry's A Raisin in the Sun, Beneatha's tone with her brother fluctuates throughout the play. However, her interactions with him are often frustrated and impatient, underlining the conflicts of their hopes and perspectives. When conversing with her brother, Beneatha can be critical and confrontational, particularly when they dispute over the use of their father’s life insurance money and their differing views on life's aspirations. Her defensive tone becomes more apparent when discussing with George, contrasting her more open and inquisitive tone with Asagai. These interactions reflect her struggle with identity, dreams, and her place within a culture and family in transition.
