I have a question about the answer to one of the "write the phrase you read" sentences in level 5, session 15. The English is "He spoke with her lawyer's(f) receptionist(f) (for) twenty minutes yesterday". The German translation is "Er hat gestern zwanzig Minuten mit der Sekretarin seiner Anwaltin gesprochen". Shouldn't it say ihrer Anwaltin? The English is "her lawyer's", not "his lawyer's".
