Read the excerpt from chapter 7 of Night. We received no food. We lived on snow; it took the place of bread. The days resembled the nights, and the nights left in our souls the dregs of their darkness. The train rolled slowly, often halted for a few hours, and continued. It never stopped snowing. We remained lying on the floor for days and nights, one on top of the other, never uttering a word. We were nothing but frozen bodies. Our eyes closed, we merely waited for the next stop, to unload our dead. How do the underlined words and phrases affect the tone of the excerpt? Select two options.
