Final answer:
Some passengers tied Madame Schacter up to silence her screams during their transport in a situation that foreshadowed the fear and desperation of the concentration camps.
Step-by-step explanation:
The passengers on the train took distressing actions to quiet Madame Schacter. Some of the passengers could not bear her screams about fire and smoke, which were a premonition of the horrors to come in the concentration camps. Consequently, rather than offering comfort or medication, they tied her up to silence her screams. This brutal response reflects the extreme conditions and mentality of people under severe stress, struggling to maintain their sanity in a situation over which they had no control.
