Respuesta :
After reading the passage I'm coming to the conclusion that the best answer would be the first one; It shows a side of Russell that doesn't make sense to others and suggests he may have other issues in the future. After reading this, it makes us all wonder "what's the deal with this guy?" So, this is the part where it makes no sense to others.
Answer:
The statement that best explains how the author's use of flashback affects the story is "It shows a side of Russell that doesn't make sense to others and suggests he may have other issues in the future."
Explanation:
The excerpt shows that the attitude of Russell is not what most people expected a young buy act like. He shows that he is very independent and that he doesn't follow anyone he has his dreams and his goals, and most of his logics are not understandable for others, then we can see how a disease can affect the behavior of characters.
