instruction:
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
question:
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.
answer:
What is the title of the person who is to be married to Prince William of Grec?

question:
Passage: For a French composer of the 19th century, opera was seen as the most important type of music. Saint-Saëns's younger contemporary and rival, Massenet, was beginning to gain a reputation as an operatic composer, but Saint-Saëns, with only the short and unsuccessful La princesse jaune staged, had made no mark in that sphere. In February 1877, he finally had a full-length opera staged. His four-act "drame lyricque", Le timbre d'argent ("The Silver Bell"), to Jules Barbier's and Michel Carré's libretto, reminiscent of the Faust legend, had been in rehearsal in 1870, but the outbreak of war halted the production. The work was eventually presented by the Théâtre Lyrique company of Paris; it ran for eighteen performances.The dedicatee of the opera, Albert Libon, died three months after the premiere, leaving Saint-Saëns a large legacy "To free him from the slavery of the organ of the Madeleine and to enable him to devote himself entirely to composition". Saint-Saëns, unaware of the imminent bequest, had resigned his position shortly before his friend died. He was not a conventional Christian, and found religious dogma increasingly irksome; he had become tired of the clerical authorities' interference and musical insensitivity; and he wanted to be free to accept more engagements as a piano soloist in other cities. After this he never played the organ professionally in a church service, and rarely played the instrument at all. He composed a Messe de Requiem in memory of his friend, which was performed at Saint-Sulpice to mark the first anniversary of Libon's death; Charles-Marie Widor played the organ and Saint-Saëns conducted.
In December 1877, Saint-Saëns had a more solid operatic success, with Samson et Dalila, his one opera to gain and keep a place in the international repertoire. Because of its biblical subject, the composer had met many obstacles to its presentation in France, and through Liszt's influence the premiere was given at Weimar in a German translation. Although the work eventually became an international success it was not staged at the Paris Opéra until 1892.Saint-Saëns was a keen traveller. From the 1870s until the end of his life he made 179 trips to 27 countries. His professional engagements took him most often to Germany and England; for holidays, and to avoid Parisian winters which affected his weak chest, he favoured Algiers and various places in Egypt.
answer:

What is the name of the person that composed the four-act "drame lyricque", Le timbre d'argent?
