Task: Question Generation
Input (English): Passage: Princess Anne plans to run away with Freddie Granton, the commoner secretary of her father, King Eric VIII, once her domineering mother, Queen Martha, has left for a vacation in America. Anne is therefore aghast when the Marquis of Birten brings news that he has negotiated her political marriage to Prince William of Grec, a man she has never even met. Dismissing Anne's vehement protests, the Queen is delighted, a feeling not shared by Anne's loving but ineffectual father.
Meanwhile, the Premier and General Northrup warn that a revolution is brewing. He wishes to execute large numbers of political prisoners, but cannot without the King's signature. The Queen wholeheartedly approves of these stern measures. The King promises to attend to it, but after Northrup and the Queen leave, he orders his secretary to misplace the death warrants. Led by Laker, the rebels rise up after Northrup gets Parliament to grant him dictatorial powers. Anne seizes the opportunity to try to flee with Granton, with her father's approval. However, when she believes that the King is in real danger, she refuses to leave him.
Doctor Fellman, a moderate rebel leader, comes to see the King to demand his abdication, but agrees to stop the fighting in favor of negotiation. Then Northrup insists he is in charge now and laughs in derision when the King claims the people are stronger than Northrup's army and navy. Next to arrive is Prince William. Despite his admission that he dislikes Anne, he is prepared to do his duty and go through with the wedding. Then Fellman and Laker show up. The King surprises Northrup by dismissing him from his service and putting Fellman in charge, ordering him to set up general elections as soon as possible.
Output (English): What is the title of the person who is to be married to Prince William of Grec?
