Answer: The author includes anecdotes about accepting her brother no matter what happens.
Explanation: These anecdotes are the most central elements of the text, because they illustrate how the family "coped" with Russell's problem, denying that he needs psychiatric help, but also accepting him as he is and trying to help him survive even in his harsh circumstances.
Part B.
Answer: "Daddy, who worked in real estate, got Russell odd jobs cleaning houses newly listed on the market, but the work wasn’t steady."
