Answer and Explanation:
The reports are similar because they show the precarious means of transport with which the Jews arrived at the concentration camps, showing how torturous the trip was and how many could hardly bear to disembark from the wagons. They also report fear, revolt and uncertainty about what would happen to their lives.
The value of these two accounts is immeasurable for humanity, as they are documents that report the tension and torture with which the Jews lived, preventing the holocaust and its histories from being forgotten. That's because holocaust survivors will end up dying over time, but reports like these will last for eternity.
