Answer:
how different circumstances have led both Dally and Darry to become who they are.
Step-by-step explanation:
In the novel "The Outisders", both Dally and Darry are the senior most members of the gang. Darry who is the eldest brother of the protagonist, Ponyboy, is physically stronger and more mature than most members of the gang. He often acts as the father figure and the guardian for most of the members of the gang.
Similarly, Dally who is also older than most members of the gang had a rough childhood growing up. It made him into an independent person at very young age. He had all kinds of experiences and many members of the gang seeked guidance from him as well.
The overall point that the author is making with these two characters is how different circumstances have led both Dally and Darry to become who they are. Darry being the oldest in the family without a father and Dally growing up with gangs and having criminal records make them more experienced and smarter than the other members.
