1) It was quite necessary not only for Buck, but also for others struggling to survive in the wild North. If he hadn't killed Spitz it it could have been very dangerous for others because he was very aggressive due to the hunger. Even though he was the leader, blinded by hunger he could do anything to survive, forgetting about the rest of dogs.
2) If he hadn't died he could have get many other innocent lives, like he had done to Curley. This character yielded to the external conflict of the harsh wild conditions, and his instings were much more powerful than his sense of justice so he could have bring harm until he reached his own safety.
The correct answer is D.
In this excerpt from "Goodbye to All That," Didion seeks to explain that the time she spent in New York went by so quickly she did not even notice. She compares her experience with that of a movie, in which several years may pass in just a minute.
She expresses that, looking back, it all feels surreal, like something that she saw on a movie.
You have to consider factors
There are multiple words to describe a character that is never developed by the author. A flat character, for example, is a character that is only defined by one or two traits and nothing else. However, in this case, I think the answer would most likely be a static character, which is a character with little to no development so as not to take away from the story being told.
