Hello !
I think the answer would be...
The last option, "The Nation has to go through significant changes to avoid such tragic wars in the future."

The correct answer is B. Since it's a small town, everyone knows everybody else.
Explanation:
In this specific story, the setting includes details such as "Country field" or "small town" because these details refer to the context and specific location of this story including the geographic and demographic features "The population barely reached 263 people". Moreover, this specific setting affects the story because it affects the characters. Indeed, this specific stetting implies in the town there are few people and they know and support each other. This is explicitly mentioned in "Everybody knew everybody". According to this, the correct answer is B.
