The correct answer is: "she had Aryan documents from her father".
Dorothea Schlösser was a half-Jewish woman, who managed to survive as a singer in Nazi Germany. Nazis usually claimed that half-breeds were even worse than Jews because they were a contamination of the Aryan Race. She was really lucky because she managed to live an ordinary life using her father's Aryan documents, while other half-breeds were directly sent to Auschwitz.
