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?
