Step-by-step explanation:
In the story 'Night' by Elie Wiesel, Elie observed the prayer service in the camp by describing the scene: 'It was dim and dark and the pillars went high up, and there were people praying, and it smelt of incense, and there were some wonderful big buildings.' Elie's observation suggests that despite the harsh conditions and bleak environment of the concentration camp, there was still a semblance of normalcy and religious practice.
