Elie is describing his family in the exposition. I would say the exposition shows the setting by telling us the customs of the people, as well as Elie's attitude and personality. It also shows where they live.
IM FREE, IM FREE
The rising action of Night is when Elie's family is taken and put in cattle cars to the concentration camps.
The climax is when Elie's father dies. this is where Elie realizing that he has nothing left to live for but he keeps going and forging through. (Elies father does not die in the fire it is just a representation)
The falling action is when Elie is failing liberated form the concentration camps but he can not decide if he can come to write about it and relive the horrors.
The resolution is when Elie can finally wake up in the morning and not see the Ghettos and he sees his father in his reflection.
The theme is when Elie lost his faith in God because of everything he has been through while at the concentration camps. I put a Nazi devil because since they tortured his people they are like the devil which made him lose his faith.
