Task: Question Answering
Input (English): Passage: French painter Michel Marnet meets American singer Terry McKay aboard a liner crossing the Atlantic Ocean. They are both already engaged, he to heiress Lois Clarke, she to Kenneth Bradley. They begin to flirt and to dine together on the ship, but his notoriety and popularity on the ship make them conscious that others are watching. Eventually, they decide that they should dine separately and not associate with each other. At a stop at Madeira, they visit Michel's grandmother Janou, who approves of Terry and wants Michel to settle down.
As the ship is ready to disembark at New York City, the two make an appointment to meet six months later on top of the Empire State Building. Michel chooses six months because that is the amount of time he needs to decide whether he can start making enough money to support a relationship with Terry.  When the rendezvous date arrives, they both head to the Empire State Building.  However, Terry is struck by a car right as she arrives, and is told that she may not be able to walk, though that will not be known for certain for six months. Not wanting to be a burden to Michel, she does not contact him, preferring to let him think the worst. Meanwhile, Terry recovers at an orphanage teaching the children how to sing.
Six months go by, and during Terry's first outing since the accident, the two couples meet by accident at the theater, though Terry manages to conceal her condition. Michel then visits her at her apartment and finally learns the truth. He assures her that they will be together no matter what the diagnosis will be. 
Question: What is the last name of the person engaged to Lois Clarke?
Output (English): Marnet.
