EDITORIAL LEARNING AID

Why is this answer correct?

For the “Leben in Deutschland” test, connect “A man is married to two women at the same time.” with the meaning of the question. This is the answer marked as correct in the official key. “A man and a woman are divorced and live together with new partners.” is not part of the solution and points to a different issue. Learn the key term together with the complete correct answer instead of memorising only its letter.
