Teacher: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.

In celebrating Christmas at Sandringham, the Queen follows the tradition of her last three predecessors, whereas her great-great-grandmother, Queen Victoria, held her celebrations at Windsor Castle. The taxation arrangements of the monarch meant that no inheritance tax was paid on the Sandringham or Balmoral estates when they passed to the Queen, at a time when it was having a deleterious effect on other country estates. On her accession, the Queen asked her husband, the Duke of Edinburgh, to take on the responsibility for the management of the estate. The Duke has worked to move towards self-sufficiency, generating additional income streams, taking more of the land in hand, and amalgamating many of the smaller tenant farms.In January 1957 the Queen received the resignation of the Prime Minister Anthony Eden at the house. Eden's wife, Clarissa, recorded the event in her diary, "8 January – Anthony has to go through a Cabinet and listening to Harold prosing for half an hour. Then by train to Sandringham. Many photographers. We arrive into the hall where everyone is looking at the television." At the end of that year, the Queen made her first televised Christmas broadcast from Sandringham. In the 1960s, plans were initiated to demolish the house and replace it with a modern residence by David Roberts, an architect who worked mainly at the University of Cambridge. The plans were not taken forward, but modernisation of the interior of the house and the removal of a range of ancillary buildings were carried out by Hugh Casson, who also decorated the Royal Yacht, Britannia. In 1977, for her silver jubilee, the Queen opened the house to the public.Sandringham continues to operate as a sporting estate. The pheasants and partridge are no longer reared for this purpose, and Sandringham is now one of the few wild shoots in England. Along with her equestrian interest in the Sandringham Stud, where she has bred several winning horses, the Queen has developed a successful gun dog breeding programme at Sandringham. Following the tradition of a kennels at Sandringham established by her great grandfather, when Queen Alexandra kept over 100 dogs on the estate, the Queen prefers black labrador retrievers, over the yellow type favoured by her father, and the terriers bred by her earlier predecessors. Since his retirement from official duties in August 2017, the Duke of Edinburgh has spent increasing amounts of time at Wood Farm, a cottage on the Sandringham Estate used by the Duke and the Queen when not hosting guests at the main house. Sandringham is one of the two homes owned by the Queen in her private capacity, rather than as head of state, the other being Balmoral Castle.
