In the poem "Do Not Go Gentle Into That Good Night", People are shown dying in the light while the people in the dark know better and stay where they are. It doesn't show anything about parents or families, so A is out. It doesn't really show anything about people being mean to each other, nor nice, so B is out. There are alot of people struggling in the light while the people in the dark stand by and stare, so C could be an option. People were dying in the light, so i don't know if D really works, so its either C or D, but C is the more likely option.
