Passage: In 1980 the band released Animal Magnetism, again with a provocative cover this time showing a girl kneeling and a Doberman Pinscher sitting in front of a man. Animal Magnetism contained classics such as "The Zoo" and "Make It Real". Soon after the album's release, Meine began experiencing throat problems. He required surgery on his vocal cords and doubts were raised about whether he would ever sing again.

Question: What part of the body did Meine  require surgery?
vocal cords
