Dorothea was able to live a relatively normal life, despite her Jewish heritage, is because:
She had Aryan documents from her father.
The answer above is the right choice among the three remaining. The other three choices does not suite the statement or rather does not fit the question so we chose the one above.
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.
