Analyze the quote by Mortiz Vegh, a Holocaust survivor: "When we got off the cattle truck, they ordered, ‘Men right; women left’ ... I went with my father. My little sister, Esther, she went with my mother. Esther was only eleven. She was holding my mother’s hand. When they made a selection of the women, Esther clung to my mother. My mother wouldn’t give her up... They went straight to the gas chamber."

Which fact about the Nazi death camps does Moritz Vegh's account support?
